Bjorn Sandvik: Mapping New Zealand: Clustering DOC Huts with Leaflet
sur Planet OSGeo

In New Zealand, long distance walking or hiking for at least one overnight stay is known as tramping. There is a great network of over 950 huts throughout New Zealand operated by the Department of Conservation (DOC). I’ve just stayed in four of the huts while tramping the Abel Tasman Coast Track, and you need a lifetime to reach them all. It’s much quicker to map them.

DOC huts in the Abel Tasman National Park.

Awaroa Hut

I was fortunate to visit the geospatial unit at the DOC office in Wellington. They have a lot of ineresting conservation projects going on, and it seemed to be a great place to work in New Zealand, especially when you can combine digital work with practical field work.

You can download DOC's geospatial data for free on their data portal. Unfortunately, the datasets are not available as shapefiles, so it might require some wizardry to extract the data from KML. Luckily, the Koordinates guys have done this already, and you can download the shapefile from their website. The version I’m using was updated 10 September 2012.

The dataset contains 967 huts, and adding them all to my Leaflet map will make it too cluttered to be useful. Instead, I wanted to try the great animated marker clustering plugin, created by Dave Leaver here in New Zealand.

I start off by converting the shapefile to GeoJSON with ogr2ogr:

ogr2ogr -t_srs EPSG:4326 -f "GeoJSON" -lco COORDINATE_PRECISION=4 nz-doc-huts.json doc-huts.shp

I could use the GeoJSON directly, but I converted it to a more compact format to save some bandwith:

var data = [
[-43.3767,170.5685,"Scone Hut",1],
[-42.9494,171.7047,"Sudden Valley Biv",0],
[-41.5237,172.5604,"Granity Pass Hut",1],
[-44.9261,168.2144,"Steele Creek Hut",0],
[-44.6221,168.4481,"Earnslaw Hut",0],
[-45.3852,167.6192,"Luxmore Hut",4],
...
];

The last number corresponds to the hut categories:

0. Basic Hut/Bivvy
1. Standard Hut
2. Serviced Hut
3. Serviced-Alpine Hut
4. Great Walk Hut

This is the code you need to create clustered huts with custom markers:

The JavaScript map function, which converts one array into another, is not supported in Internet Explorer 8 and lower. If you need to support prehistoric browsers, use a for-loop instead. The icons I’ve used (which could have been more descriptive) are from Map Icons Collection.

The interactive map looks like this:

I especially like the animated feature of this clustering plugin (try zooming in and out), as it makes it more obvious for the map user what a cluster really is.

G8 leaders sign charter on open data including geospatial and infrastructureBetween the Poles
sur Planet Geospatial - http://planetgs.com
G8 leaders (Canada, France, Germany, Italy, Japan, Russia, United Kingdom, United States, and the European Union) signed a charter on open data. The Open Data Charter sets out 5 strategic principles that all G8 members will act on. G8 members also identified 14 high-value sectors from which they will release data which include geospatial and infrastructure.

Motivation

Technology and increasing volumes of information have created an enormous potential to enable more accountable, efficient, responsive, and effective governments and businesses and to spur economic growth.

"Open data sit at the heart of this global movement." Governments and businesses collect a wide range of data, but mich of this date remains unaccessible.

Open data also increases transparency about what government and business are doing which promotes accountability and good governance.

Government open data is a catalyst for innovation in the private sector, supporting the creation of new markets, businesses, and jobs. Government open data practices are also a model for the private sector encouraging businesses to recognize the value of open data and to adopt open data policies.

Open data principles

The G8 countries aggredd to a sset of principles agree to follow a set of principlesthat are the foundation for access to, and the release and re-use of, data collected by by G8 governments.

Principle 1: Open Data by Default

G8 governments will establish an expectation that all government data be published openly by default, while recognising that there are legitimate reasons why some data cannot be released.

Principle 2: Quality and Quantity

G8 governments will release high-quality open data that are timely, comprehensive, and accurate in their original, unmodified form and at the finest level of granularity available.

Principle 3: Usable by All

G8 governments will release data in open formats wherever possible. In many cases this will include providing data in multiple formats.

Principle 4: Releasing Data for Improved Governance

G8 governments will transparent about their own data collection, standards, and publishing processes, by documenting all of these related processes online. This includes a G8_Metadata_Mapping initiative that is documented on Github which shows the mapping between the metadata on datasets published by G8 Members through their open data portals.

Principle 5: Releasing Data for Innovation

G8 governments will work to increase open data literacy and encourage people, such as developers of applications, by providing data in machine-readable formats.

Key high-value sectors

G8 members identified 14 high-value sectors from which they will release data.
- Crime and Justice - Crime statistics, safety
- Earth observation - Meteorological/weather, agriculture, forestry, fishing, and hunting
- Education- List of schools; performance of schools, digital skills
- Energy and Environment - Pollution levels, energy consumption
- Finance and contracts - Transaction spend, contracts let, call for tender, future tenders, local budget, national budget (planned and spent)
- Geospatial - Topography, postcodes, national maps, local maps
- Global Development - Aid, food security, extractives, land
- Government Accountability and Democracy - Government contact points, election results, legislation and statutes, salaries (pay scales), hospitality/gifts
- Health - Prescription data, performance data
- Science and Research - Genome data, research and educational activity, experiment results
- Statistics - National Statistics, Census, infrastructure, wealth, skills
- Social mobility and welfare - Housing, health insurance and unemployment benefits
- Transport and Infrastructure - Public transport timetables, access points broadband penetration

Bjorn Sandvik: How to minify GeoJSON files?
sur Planet OSGeo
You can't do web mapping these days without knowing your GeoJSON. It's the vector format of choice among popular mapping libraries like Leaflet, D3.js and Polymaps. Size matters on the web, especially if you want to distribute complex geometries, like the world's countries. The challenge is even bigger if you want to target mobile users - or support web browsers with poor vector handling (IE < 9). This blog post will show you how to minify your GeoJSON files before sending them over the wire.

The first thing you should do is to generalize your vectors so they don't contain more detail than you need. In a previous blog post, I was able to remove 90% of the coordinates without loosing to much detail for map scale I wanted to use. This will of course have a great effect on the file size.

Today, I'm going to use country borders from the Natural Earth dataset. These datasets are already generalized for different scales (1:10m, 1:50m, and 1:110 million), so I'll use them as they are. The 1:110m (small scale) and 1:50m (medium scale) shapefiles will cover the needs for the thematic world maps I plan to make:
- 110m-admin-0-countries
- 50m-admin-0-countries
The 110m and 50m country polygons shown in QGIS.

Let's open the datasets in QGIS. If you look at the attribute table you'll see that each dataset contains 63 attributes, which makes them very versatile. For your web maps, you probably need just a few of the attributes, and you should remove the ones you don't need. I'm keeping the country name and the ISO 3166-1 country codes (alpha-2, alpha-3, and numeric), which can be used to link country geometries to statistical data.

Only keep the attributes you need.

Next, we can convert the shapefiles to GeoJSON with ogr2ogr:

ogr2ogr -f "GeoJSON" -lco COORDINATE_PRECISION=1 ne_110m_admin_0_countries.json ne_110m_admin_0_countries.shp

ogr2ogr -f "GeoJSON" -lco COORDINATE_PRECISION=2 ne_50m_admin_0_countries.json ne_50m_admin_0_countries.shp

The important thing is that I'm only keeping one decimal (coordinate precision) for the 110m dataset, and two decimals for the 50m dataset, which is sufficient for my map scales. This will reduce the size of the GeoJSON files by more than half. The size of the 110m GeoJSON is now 207 kB and the 50m version is 1,897 kB. But we can do better.

The files contains a lot of whitespace, which is waste of space. I planned to use Sublime Text to remove the whitespace, but it were not able to handle the 50m GeoJSON file, so I switched to Notepad++. I used these regular expressions:

Find: "([^a-z.]) "
Replace: "$1"
This will remove all whitespace which is not succeeding a letter or a dot, which are present in country names.

Find: "\n,"
Replace: ","
Remove line breaks (keeping some for readability).

Find: "\.0([,\]])"
Replace: "$1"
Remove trailing zeros.

This will reduce the file size of the 110m GeoJSON from 207 to 156 kB, without loosing any data quality. More than 400k of whitespace characters was removed from the 50m GeoJSON file, reducing the file size from 1,897 to 1,481 kB.

If your web server is supporting gzipping on-the-fly, the 110m GeoJSON will end up being 45 kB and the 50m version will be 430 kB. Not bad!

And if this is too much work, you can always download the final GeoJSON files on thematicmapping.org.

NB! Mike Bostock’s TopoJSON would allow us to compress the GeoJSON even more, while preserving topology (shared borders between countries) - but we would need to use a map client supporting the format. Looks promising!

Bjorn Sandvik: Showing Zoomify images with Leaflet
sur Planet OSGeo

Today, I'm starting a new blog series written from Foldøy, a tiny island in south west Norway which will be my home for two months. In this first post, I'll show you how to deliver zoomable high-resolution images with Leaflet.

I've brought along 17 kg of mapping and visualization books to keep me occupied:

Fullscreen

Zoom in if you want to see the details! The photo is broken into tiles and then displayed as required. You don't really need Leaflet to create images like this, as Zoomify provides both Flash and HTML5 viewers. I decided to use Leaflet to create an open source alternative, and to learn more about tiling schemes.

This is the JavaScript code needed to show this image:

var map = L.map('photo').setView(new L.LatLng(0,0), 0);

L.tileLayer.zoomify('http://thematicmapping.org/playground/zoomify/books/', {
width: 5472,
height: 3648,
tolerance: 0.8,
attribution: 'Photo: Bjørn Sandvik'
}).addTo(map);

You have to provide the url to the Zoomify image folder and the with and height dimensions of the original image. You can also specify a display tolerance for the inital zoom level. A value lower than 1.0 might center the image and cut of the edges.

Image source: Microsoft Deep Zoom

The Zoomify tile format is similar to popular map tiling schemes, and I'm extending the Leaflet TileLayer class to show the image. The tiling follows a quadtree or pyramid pattern of increasing resolution, doubling the resolution for each zoom level. The tile size is 256 x 256 px and there are 256 tiles in each folder. The filename for each tile is z-x-y.jpg where z is the zoom level and x/y is the grid position starting from the top left corner.

The code is available on GitHub as a Leaflet plugin.

Find Photogenic Locations with Google Maps
sur Google Maps Mania

ShotHotspot is a great resource that helps both professional and amateur photographers find great locations to take photos.

The application uses data from sites like Flickr and Panoramio to analyse the most photogenic areas. ShotHotspot's Google Maps allows users to scout for locations around any location worldwide. It is possible to narrow down the area of search by drawing the area you are interested on the map. It is also possible to zoom in on a location and update the results shown by selecting the 'Search Visible Area'.

You can select any of the hotspots displayed on the map and preview the photo opportunities by viewing photographs of the location taken by other photographers which have been posted to Flickr or Panoramio.

Automating the Windows Map AppMaps Blog

sur Planet Geospatial - http://planetgs.com

Windows allows a Windows Store application to register as the default handler for a certain URI schema. This process is called Protocol Activation and it can be leveraged in the WinRT as well as the WinJS framework.

The Windows Map app is registered for protocol activation and the URI schema is documented here. Through protocol activation you can control the map view, find places or business listings, calculate routes or even map entire collections of points of interest.

In this quick example, we use this capability to display the location where we captured a photo. Rather than starting from the scratch, we build upon the Simple Image Sample from the Windows Dev Center. The first scenario in this application reads and writes properties of an image – including the coordinates (latitude and longitude) where we captured the photo.

There are a few changes that we need to apply to this app in order to launch the Map app and center on this location.

In the application markup language of scenario 1 we do the following:

Replace the boxes for degrees, minutes and seconds as well as the one for the compass orientation with a single text-box in which we will display the latitude and longitude in decimal degrees.
Add a button that will launch the Map app with parameters.

The new XAML will look like this:

TextBlock Grid.Column="0" Grid.Row="6" TextWrapping="Wrap" 
	 Style="{StaticResource BasicTextStyle}" 
	 HorizontalAlignment="Left" VerticalAlignment="Center">Latitude
TextBlock> 
TextBox Grid.Column="1" Grid.Row="6" Margin="0,0,10,10" x:Name="LatTextbox" 
         HorizontalAlignment="Left"  Text="" Width="300" /> 


TextBlock Grid.Column="0" Grid.Row="7" TextWrapping="Wrap" 
	 Style="{StaticResource BasicTextStyle}" 
	 HorizontalAlignment="Left" VerticalAlignment="Center">LongitudeTextBlock> 
TextBox Grid.Column="1" Grid.Row="7" Margin="0,0,10,10" x:Name="LonTextbox" 
         HorizontalAlignment="Left" Text="" Width="300" /> 

Button x:Name="myPhotoLoc" Grid.Column="1" Grid.Row="8" 
        Click="myPhotoLoc_Click" Width="300" Margin="0,0,10,0" >Open MapButton>

Next we look at the code behind and in the function GetImagePropertiesForDisplay. We replace the code that splits the coordinates in degrees, minutes and seconds with the snippet below.

' Do a simple check if GPS data exists. 
   If  (m_imageProperties.Latitude.HasValue) AndAlso  (m_imageProperties.Longitude.HasValue) Then 
     LatText = Math.Round(m_imageProperties.Latitude.Value,  6).ToString
     LatTextbox.Text = LatText
  LonText = Math.Round(m_imageProperties.Longitude.Value,  6).ToString
  LonTextbox.Text = LonText
 End If

We also introduce a new function to handle the click-event on our button and launch the Map app:

Private Async Sub myPhotoLoc_Click(sender As Object, e As RoutedEventArgs)
  ' Create the URI to launch  from a string. 
  Dim uri = New Uri("bingmaps:?collection=name.Photo%20Locations~point." + _
     LatText + "_" + LonText + "_My%20Photo&sty=a")
  ' Launch the URI. 
  Dim success As Boolean = Await Windows.System.Launcher.LaunchUriAsync(uri)
End Sub

And that’s it. You’ll find the complete source code here.

Happy Mapping ☺

[INSPIRE by clouds] Une méthode pour affecter une série au "bon" thème
sur GeoRezo.net - Géoblogs

Une série de billets tentent d'expliquer à quel thème (dominant) affecter telle ou telle série de données.

Suite à des échanges avec un honorable correspondant, par exemple sur l'affectation de séries de données relatives aux mines et carrières, j'ai pensé utile de vous découvrir la méthode infaillible pour trouver à quel thème affecter une série de données lorsqu'on en saisi les métadonnées.

En fait, il y en a deux, mais la première consiste à connaître par cœur les 600 pages. Normalement, ce n'est pas votre cas, on va donc faire autrement.

La méthode demande un clavier, un écran et une connexion internet (au moins au départ).
1/ Récupérer le texte en français du (projet de) règlement sur les spécifications des annexes II et III. C'est ici (. doc, 2,8 Mo).
2/ Rechercher le mot clé lié à votre série de données.
3/ Rechercher encore pour être sûr d'avoir bien balayé tout le texte.
4/ Voir dans quelle partie c'est. Vous avez le thème.

Application sur "mines" :
Les deux premières occurrences sont trouvées dans la définition d'un "talus de déblais" et de "feux de mines". Passons.

Les mines et carrières (description des objets physiques et juridiques) sont dans le thème « ressources minérales ». Voilà.

Il y a bien la notion d' "Industries extractives" dans le thème III-4 "Usage des sols". Comme vous êtes habiles, vous voyez vite que ce ne sont que des attributs de zones dans les documents d'urbanisme.

Facile, non?

Il est possible que vous ne trouviez pas quelques séries dans ce règlement alors qu'elles sont bien dans INSPIRE (les photos obliques de crue...). Cela s'explique par le fait qu'elles sont trop rares pour valoir la peine de normaliser leur structure.
Toutefois, la plupart du temps absence vaudra exclusion du champ. Exemple : les terrains de camping.

Entre passé et projet: le rapport à l’histoire et aux identités politiques dans les atlas modernes
sur Cartes et figures du monde

Entre passé et projet: le rapport à l’histoire et aux identités politiques dans les atlas modernes

Troisièmes Journées d’étude du groupe ACSAM

Ecole Française de Rome

20 et 21 juin 2013

Présentation des thèmes des Journées d’étude :

Le groupe ACSAM (« Les atlas dans les cultures scientifiques et artistiques modernes et contemporaines ») propose deux journées d’étude sur les atlas, envisagés dans la perspective de la représentation du rapport à l’histoire, d’une part, et dans celle de la construction des espaces et des identités politiques, d’autre part.

La première journée sera consacrée à une réflexion collective sur les atlas historiques produits à l’époque moderne et contemporaine. Comme on sait, dès le XVI^e siècle, dans les éditions « révisées » de la Géographie de Ptolémée, la question du rapport au passé a été rencontrée. De même, parallèlement à son Theatrum orbis terrarum, Abraham Ortelius a dessiné des cartes historiques, qui progressivement ont donné naissance à un ouvrage spécifique intitulé Parergon. Ortelius ouvrait ainsi la voie à une série d’atlas explicitement dédiés à la représentation du passé sous diverses formes : histoire religieuse, histoire civile, histoire poétique ou littéraire. Cette histoire n’est pas achevée, loin de là, puisque, aujourd’hui encore, de très nombreux atlas historiques sont publiés.

Les questions que nous souhaitons aborder lors de cette première journée sont les suivantes :

-                Comment ces atlas et recueils qui représentent l’histoire à l’aide de la cartographie sont-ils conçus et élaborés ? Selon quels principes graphiques et éditoriaux ? Quelle est, en général, la forme adoptée pour les atlas historiques ? En quoi est-elle spécifique, le cas échéant ?

-                Quels sont les contenus de ces atlas ? Quels objets historiques représentent-ils ? Selon quels types de périodisation ? Quels sont les styles iconographiques mis en œuvre dans ces recueils ?

-                Quels sont les acteurs engagés dans la fabrication des atlas historiques ? Quels auteurs ? Quels graveurs ? Quels éditeurs ? Plus généralement : quels réseaux de production et de diffusion ?

-                Enfin, quels sont les discours historiques qui sont véhiculés au sein de ces atlas ? Quelles sont les histoires qui sont racontées ? Autrement dit, quelles sont les modalités de la configuration du temps qui sont mis en œuvre dans les atlas historiques ?

L’objectif de cette première journée est de parvenir à une analyse comparative d’atlas fabriqués à différentes dates (entre le XVII^e et le XXI^e siècle), dans différents centres de production européens et non-européens, et dans différents contextes socio-politiques, afin de poser de façon globale le problème des modalités de la représentation du passé dans les atlas historiques.

La seconde journée de ces rencontres sera dédiée à la présentation d’analyses consacrées au rôle des atlas géographiques dans la fabrication des territoires et des identités politiques. La fonction politique des atlas est bien connue. C’est dans les atlas que les lecteurs modernes ont appris les découpages territoriaux et les hiérarchies politiques, les centres et les périphéries, et qu’ils ont pu suivre la succession des conflits et des revendications identitaires à propos des territoires cartographiés.

Les thèmes qu’on aimerait aborder lors de cette seconde journée sont les suivants :

-                Quelle est la rhétorique politique spécifique mise en œuvre dans les atlas ? Quels sont les objectifs ? Les modèles et les formes ? Les revendications ? Portées par quels groupes d’acteurs ?

-                Que peut-on savoir de la diffusion de ces atlas ? De leur usage ? De leur implication dans les entreprises politiques ? Par exemple lors des litiges frontaliers ?

-                Comment, dans ces atlas, les territoires sur lesquels le contrôle politique est revendiqué sont-ils représentés ? Comment leur « identité », leur « substance », leur « caractère », sont-ils montrés, présentés ? Notamment dans le cas des atlas nationaux ?

-                Est-il possible de saisir une différence dans les opérations graphiques et rhétoriques mises en œuvre dans les atlas dédiés à la représentation de territoires d’échelles différentes : atlas nationaux, impériaux, universels par exemple.

Au total il s’agit, dans cette seconde journée, d’analyser la fonction et la portée politiques des atlas dans la période moderne et contemporaine, de faire apparaître pour ainsi dire leur efficience politique.

François Mazuyer réélu pour deux ans à la présidence du Conseil supérieur de l’Ordre des géomètres-experts
sur DécryptaGéo, l'information géographique

Paris, le 19 juin 2013

François Mazuyer, Président du Conseil supérieur de l’Ordre des géomètres-experts depuis juin 2011, vient d’être réélu à la tête de l’institution ordinale. L’élection a eu lieu au cours de la séance du Conseil supérieur du 18 juin 2013 après le vote de l’ensemble des membres de conseils régionaux de l’Ordre.

.

François Mazuyer a été réélu par l’ensemble des membres du conseil supérieur pour poursuivre les grands projets de la profession dans lesquels il s’était investi lors de son premier mandat (2011-2013). « Depuis 2011, de nombreux projets ambitieux ont été mis en œuvre, comme le lancement du premier Code du géomètre-expert, une large réflexion sur la stratégie de communication de la profession, un congrès sur la copropriété en 2012 à La Rochelle, la réforme du DPLG pour l’accès à la profession ou encore l’intégration des géomètres mahorais au tableau de l’Ordre ». Décidé à guider la profession de géomètre-expert dans l’actuel contexte économique difficile, François Mazuyer considère que tous ces projets ont « constitué autant de manière de moderniser la profession et mettre en évidence son rôle dans son environnement ». Toujours présente sur le terrain international, auquel est particulièrement attaché le président, la profession a travaillé à la fois au niveau européen pour harmoniser les pratiques, en participant activement à la rédaction d’un code de mesurage des surfaces européen, et auprès des pays émergents pour partager son expérience et former des géomètres-experts.

De nouveaux défis pour les deux ans à venir

Le Conseil supérieur de l’Ordre des géomètres-experts, en partie renouvelé, a, de nouveau, accordé sa confiance à François Mazuyer, qui a exprimé ses objectifs pour le mandat qui s’ouvre. Après avoir invité chacun à « intensifier ce qui a été mis en place pour développer au sein des cabinets les activités d’entremise, de gestion et d’évaluation, porteuses d’avenir », il a partagé avec ses confrères et consœurs les projets phares de la période « 2013-2015, avec des ambitions en termes de stratégie d’influence aussi bien au niveau national qu’international » ainsi que « le développement d’une véritable politique de recherche et développement au service de la profession ». Enfin, François Mazuyer a rappelé les enjeux du prochain congrès, en 2014, sur le thème Risque et aménagement, qui permettra à la profession de proposer des approches novatrices de l’aménagement dans des zones particulièrement difficiles et sera l’occasion de dévoiler le projet de « Cadastre Marin ». François Mazuyer, pourra s’appuyer sur un Bureau du Conseil supérieur lui aussi entièrement reconduit dans ses fonctions pour la mise en œuvre de ces projets.

A propos de François Mazuyer

Géomètre-expert DPLG, François Mazuyer est inscrit au tableau de l’Ordre des géomètres-experts depuis 1980. Il exerce la profession depuis plus de 32 ans. Tout d’abord, en exercice individuel et actuellement comme associé de la SARL ARGEO[1] dans les Landes. François Mazuyer est également expert immobilier près la Cour d’Appel de Pau et enseignant formateur. Son souci de l’éthique professionnelle et son sens de la médiation en font un expert judiciaire apprécié et reconnu. Ses qualités de pédagogue sont unanimement saluées et le consacrent comme l’un des maîtres référents de l’enseignement du bornage en France mais aussi dans les pays francophones.

gvSIG Team: gvSIG 2.0: “Crime” symbols library
sur Planet OSGeo

Some weeks ago we published a symbols library oriented to emergency management, both at a urban level and a natural disaster level. As a complement and in order to ease the representation of symbols for those gvSIG users who are related with criminology and delictual analysis, we have created a new symbols library.

In this case we created the line and fill symbols manually and for the marker symbols we used the text font called “CMS. The Crime Mapping Symbology”.

These public domain symbols were designed for the US Justice Department specifically for meeting the needs of the police department about symbology, although due to its thematics, it can be also used for other departments as fire fighters. CMS includes itself two symbol sets called “Computer Aided Dispatch (CAD)” and “Records Management System (RMS)”.

We generated the different selection symbols with GIMP. In this case, as there were some yellow symbols, we decided that the selection symbols were in grayscale. Doing Image/Mode/Grayscale we converted the original symbols to grayscale ones, adding “_sel” to the file name in order that gvSIG can use it automatically.

These symbols are designed to be used at a size of 32 pixels, although we still can view them correctly if we make them smaller. This package is available within the gvSIG addons manager (selecting the URL [downloads.gvsig.org] and searching by “Types/symbols”) or directly downloading the package from here.

Petr Pridal: Bounding Box Tool
sur Planet OSGeo

Marc McGee from the Harvard University Library has written a great steb-by-step guide on how to use the Bounding Box Tool developed and maintained by Klokan Technologies GmbH.

The practical online tool for (not only) map librarians is freely available at the address [boundingbox.klokantech.com] and it allows visual selection of geographic coordinates for direct copy&paste into a library system during cataloguing in various formats such as MARC, DublinCore, CSV or KML.

The article has been published in the recent issue of the »base line« newsletter (Volume 34, Number 3, June 2013, ISSN 1943-6548) in the section »On the cataloging/cataloguing front« edited by Tammy Wong from the Library of Congress.

Base line is an official publication of the American Library Association’s Map and Geospatial Information Round Table (MAGIRT).

The complete text is open access and freely available online at: [www.ala.org]

We are keen to further develop such online tools in future and help with the geospatial search applications in large map catalogues and with community engagement through our Georeferencer and MapRank Search technologies.

It is really a pleasure to see our work appreciated by many map librarians all over the world!

GeoJSON on GitHub: Now What?geoMusings
sur Planet Geospatial - http://planetgs.com
So GitHub announced that you can now automatically view any GeoJSON files that may be in a repository inside an interactive map driven by MapBox technology. This simple enhancement to GitHub is probably one of the most significant developments in the geospatial industry in years. I’ll explain a little later in this post. It’s also important to view this new capability as a great, but limited, first step. I’ll discuss that a little later as well.

While it’s cool to click on a link and just see a map, it doesn’t take long to wonder about how you can use this capability beyond viewing data in GitHub. What follows are three ways to capitalize on GeoJSON in GitHub. Not all are directly related to the new mapping capability, and two have been possible for a long time. That said, the GitHub announcement may draw interest from users who have not previously considered either GitHub or GeoJSON, so I hope these approaches will be useful.
- Embed the GitHub map.
If you click on a GeoJSON file and view the new map in GitHub, a quick view of the page source will show that this map is embedded in an IFRAME object. This approach can be used to embed the GitHub map in any page. It’s a great way to quickly publish a data set while also providing access to download the raw data.

Viewer requires iframe.
- Stream the data into your own web map.
This is not a new capability; if you’ve had GeoJSON in a repo, you’ve always been able to do this. That said, if you’re checking out GitHub or GeoJSON for the first time as a result of the new mapping capability, this is something you may want to try. I have had a page up for a while showing the county-by-bounty breakdown of Maryland’s marriage equality question from the 2012 election that uses this approach to load the data into a Leaflet map from GitHub and style it. (Incidentally, the tiles in the map are also hosted on GitHub.)
- Stream the data into your desktop.
A third option is to stream the GeoJSON data directly into desktop GIS software such as QGIS for further analysis. In QGIS, simply need to add a vector, specifying “Protocol” and entering the URL to your GitHub-hosted GeoJSON file. Make sure you use the “raw” URL that looks something like this: [https:] .

After a few seconds (or more depending on the file size), it should load into QGIS like this:

Additionally, the GDAL/OGR plug-in for ArcGIS by AmigoCloud provides a way to get GeoJSON into ArcMap, though you may need to download the data first.

UPDATE: Dane Springmeyer pointed out that TileMill supports remote URLs as well.

@geomusingsblog @billdollins - very cool, had no idea QGIS supported remote urls. TileMill does also: [t.co]
— Dane Springmeyer (@springmeyer) June 19, 2013

Those are three (or so) quick ways to capitalize on GeoJSON data in GitHub now. So what next?

I stated earlier that I think the GitHub announcement was one of the most significant developments in years. I think it is best explained by feoMike in his recent post. As he points out, GitHub has made it easy to communicate spatial information in a way that is fully consistent with the web. Now that simple mapping is available to a large community of developers, it will be interesting to see where they take it. feoMike offered up a few early examples in his post. It’s worth a read.

The GitHub move is great for GeoJSON as a format. I’ve said in the past that the search for the next shapefile ends with GeoJSON. If the web is this generation’s dominant computing platform (it is), then GeoJSON provides a simple, elegant solution for geographic data transport in a manner that the shapefile did for the desktop. Support by GitHub is one more example of the community voting with its code as to what it prefers.

I also said it was a great first step, but limited. The mapping capability is understandably basic, though the documentation shows how you can customize styling somewhat. There is also a point at which the data seems to become too big to render (in either the map or in raw form). Bill Morris has identified this limit to be in the ballpark of 4.5MB, which can be easy to hit with GeoJSON.

@byrne_tweets @BenBalter @ericg @ajturner +1 for a solid number on max renderable filesize. 4.5MB is pushing it: [https:]]
— Bill Morris (@vtcraghead) June 18, 2013

So this means that enterprises won’t be dumping terabytes of vectors to GeoJSON and loading them into GitHub. That’s a good thing in my book. It is, however, an acceptable solution for small data sets and quick turn-around data sharing. As with all things, you have to go in with the right set of expectations.

The thing I’m probably least worried about is how this affects Esri. Without any specific inside knowledge of Esri’s plans, I suspect some form of official support for GeoJSON isn’t far off. There are too many people inside Esri who get GeoJSON for it not to happen. If anything, the GitHub announcement may provide a bit of a push by providing a potentially rich source of data sets to consume. The real question is what form the support will take. In any event, Esri provides enough APIs to enable us to develop our own support for GeoJSON if we need it.

The addition of GeoJSON mapping to GitHub is a very small change in the scheme of that platform, but such small changes can sometimes lead to big shifts. It has been possible for a long time to use GitHub to host geospatial data for applications. The main benefit of this latest change, in my opinion, is its potential to get people thinking about the platform in a different way. With such a visible (and visual) change on a platform targeted at developers, I hope that it will motivate that community to begin experimenting with how far it can be pushed. If a hosted platform with an already-baked-in workflow for change management and version control begins to be viewed as a viable home for spatial data, it has the potential to change how the geospatial community thinks about how it does business.

Increased urbanization is creating megaregionsBetween the Poles
sur Planet Geospatial - http://planetgs.com
I've blogged about the Delhi Mumbai Industrial Corridor, (DMIC) a huge US$ 90 billion project 1,483 km in length linking Delhi and Mumbai. The objective of the DMIC is to create a base for economic development by providing access to the best state-of-the-art infrastructure. This project includes nine large Industrial zones of about 200-250 km²., a high speed freight line, three ports, six airports and a 4000 MW power plant. An influence region of 150 km on either side of the freight line comprises the DMIC. It strikes me that what is being created is a megaregion, a concept that is getting a lot of attention in the United States,

A megaregion is a new scale of geography that blurs the traditional boudaries between metropolitan regions, like what the DMIIC is doing with respect to Mumbai, Delhi and other smaller cities. These population centers include Interlocking economic systems, shared natural resources and ecosystems, and common transportation systems. Population growth and increasing urbanization are the driving forces behind megaregions.

America2050 has defined 11 megaregions in the United States. Megaregions are defined by relationships that define a common interest.. According to Amerca2500 the five major categories of relationships that define megaregions are:
- Environmental systems and topography
- Infrastructure systems
- Economic linkages
- Settlement patterns and land use
- Shared culture and history
Most of a country's rapid population growth and economic expansion is expected to occur in these megaregions.

These aggregations are so large that they need to be modeled and managed as smart cities. For example, the Delhi Mumbai Industrial Corridor (DMIC) is intended to be comprised of seven smart cities. According to URENIO these smart cities are compact, vertical developments. They use digital technology to create smart grids for better management of civic infrastructure. They have an efficient public transportation system. They recycle sewage water for industrial use. Green spaces, cycle tracks and easy accessibility to goods, services and activities are designed to foster a sense of community.. They have underground utility corridors for parking, sewage disposal and communication lines. Public transport is available within a 10-minute walk from home or office.

How To Load Spatial Data From SQLite In A Windows Store AppMaps Blog

sur Planet Geospatial - http://planetgs.com

Sometimes it can be helpful to hold geospatial data locally and to distribute it with the application. In this example, we will use SQLite to store geospatial information and visualize it as a layer in the Bing Maps Control for Windows Store Apps.

SQLite is a software library that implements a self-contained, server-less, zero-configuration, transactional SQL database engine.

Preparing the Data

For this example we will be using trails which we retrieved from the King County GIS Data Portal. This data is available in Esri Shapefile format with coordinates in the North American Datum 1983 (NAD83) system. I converted them into a SQLite database with coordinates described as latitudes and longitudes with decimal degrees in the World Geodetic System 1984 (GS84) using the ogr2ogr command-line tool from Geospatial Data Abstraction Library (GDAL). The command for this conversion is:

ogr2ogr.exe -f sqlite -lco FORMAT=WKT "D:\Downloads\GeoData\King County\trail_SHP\trail.db" 
"D:\Downloads\GeoData\King County\trail_SHP\trail.shp" -t_srs EPSG:4326

Prerequisites

Since we are developing a Windows Store App, we need access to a Windows 8 machine as well as Visual Studio 2012. A free version of Visual Studio Express 2012 for Windows 8 is available here.

For this project we require the “Bing Maps SDK for Windows Store Apps” as well as “SQLite for Windows Runtime” you can install both from Visual Studio 2012 by selecting “Extensions and Updates” from the menu “Tools” and searching for the respective SDKs in the online gallery.

We will also require a Bing Maps Key. If you don’t have one yet, you can follow the instructions to get a free trial or basic key.

Preparing the Project

Let’s start by creating a new project using the blank Visual C# template for Windows Store Apps.

Next we add references to the Bing Maps SDK, the Visual C++ Runtime and SQLite.

The Bing Maps SDK requires that we compile separately for each processor architecture. So we need to open the “Configuration Manager” and change the platform from “Any CPU” to a specific one – here “x64”.

We also require the “sqlite-net” library and we can add this from NuGet by opening the menu “Tools” → “Library Package Manager” → “Manage NuGet Packages for Solution” and searching for “sqlite-net”.

Finally we add the SQLite database trail.db to the folder “Assets” of the project, set the property “Build Action” to “Content” and “Copy to Output Directory” to “Copy if Newer”.

Adding the Application Markup

Now that our project is prepared, we open the MainPage.xaml add the namespace for the Bing Maps control and define the user interface. In the user interface, we load Bing Maps centered to a location in King County at zoom-level 13 and specify that we want to display the aerial imagery.

   		   Grid.Row="2"/>

Page>

Adding the Code-Behind

In the code-file MainPage.xaml.cs we define a class that describes the SQLite table.

public class trail 
{
    public string OGC_FID { get; set; }
    public string WKT_GEOMETRY { get; set; }
    public string kc_fac_fid {  get;  set; }
    public string trail_name {  get;  set; }
    public string trail_type {  get;  set; }
    public string surf_type {  get;  set; }
    public string sitefacfid {  get;  set; }
    public string sitename {  get;  set; }
    public string sitetype {  get;  set; }
    public string owner {  get;  set; }
    public string ownertype {  get;  set; }
    public string manager {  get;  set; }
    public string managertype {  get;  set; }
    public string maintd_by {  get;  set; }
    public string mainttype {  get;  set; }
    public string shape_len {  get;  set; }
 }

For the class that will actually read the data and display it on the map, we import three libraries:

using Bing.Maps;
using Windows.Storage;
using Windows.UI.Popups;

The class that reads the trail-database copies it first in the local application directory. It creates a MapShapeLayer, reads through the table-records and adds the records for the trails to the layer before it adds the entire layer to the map.

One point to call out here is that the data is stored as Well Known Text (WKT) in SQLite. The WKT has the coordinates in the order Longitude and then Latitude while Bing Maps expects them in the order Latitude and then Longitude. So we have to swap the order of the coordinates.

public async void GetTrails()
{
   var uri = new Uri("ms-appx:///Assets/trail.db"); 
   var file = await StorageFile.GetFileFromApplicationUriAsync(uri);
   var destinationFolder = ApplicationData.Current.LocalFolder;//local appdata dir 
   try 
   {
   await  file.CopyAsync(destinationFolder); //copied application local folder}} 
   }
   catch { }
   
   var dbpath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "trail.db");
   var db = new SQLite.SQLiteConnection(dbpath);
   var trails = db.Tabletrail>();
   MapShapeLayer  shapeLayer = newMapShapeLayer();
   int numLocs = 0;
   int numTrails = 0;
   foreach (trail thisTrail in trails)
   {
   var wkt =  thisTrail.WKT_GEOMETRY.Replace("LINESTRING  (" , "").Replace(")", "");
   string[] wktArray = wkt.Split(',');
   LocationCollection bmPolylineLocs = new LocationCollection();
   for (var i = 0; i  var loc = wktArray[i];
   var locArray = loc.Split(' ');
   bmPolylineLocs.Add(new Location(Convert.ToDouble(locArray[1]), 
   Convert.ToDouble(locArray[0])));
   numLocs  = numLocs + 1;
   }
   MapPolyline bmPolyline = new MapPolyline();
   bmPolyline.Locations = bmPolylineLocs;
   bmPolyline.Color = Windows.UI.Colors.Red;
   bmPolyline.Width = 5;
   shapeLayer.Shapes.Add(bmPolyline);
   numTrails  = numTrails + 1;
  }
  myMap.ShapeLayers.Add(shapeLayer);
  var myMsg = new MessageDialog("Loaded " + numTrails.ToString() + 
   " with " + numLocs.ToString() + 
   " locations" );
   await myMsg.ShowAsync(); 
}

Finally we add a call to this new class right after we initialize the app.

public MainPage()
{
  this.InitializeComponent();
  GetTrails();
}

And that’s it. Below you see a screenshot of the trails in King County on top of Bing Maps.

Happy Coding! ☺

Slashgeo (FOSS Articles): Exclusive Q&A with OpenGeo
sur Planet OSGeo

Recently OpenGeo announced that they’ve taken on funding and spun out from their not-for-profit parent organization, OpenPlans. OpenGeo is major player offering mature open source geospatial solutions based on solid software such as PostGIS, GeoServer, OpenLayers and much more, including their open source all-in-one OpenGeo Suite. Here's our exclusive Q&A with OpenGeo.

Slashgeo: What were the real-life limitations of the not-for-profit model that OpenGeo wants to get rid?

OpenGeo: To pursue our mission of growing open source geospatial software communities we truly need be independent. While we are very supportive of the OpenPlans’ (our incubator parent non-profit) mission, our ability to set our own course and be responsive to the needs of our customers and communities was limited until this spin-off. There were additional, more mundane limitations, such as an inability to directly compete as a “small business” (non profits are not businesses), and the difficulty in raising capital as a not-for-profit.

Slashgeo: Does this change allow OpenGeo to become even better competitors to other commercial and open source geospatial solutions providers?

OpenGeo: It allows us to better execute our “Spatial IT” initiatives, so “yes.” We will be hiring more staff to enhance the user experience of our software, increase documentation and build additional capabilities. We believe all aspects of our work will benefit from our independence and increased funding.

Slashgeo: Do you foresee any impact on the diversity of the solutions you're offering? Do you plan to build capacity and expertise for other currently popular open source services that OpenGeo doesn't currently offer?

OpenGeo: That is something we are looking at very seriously. Many of our customers have asked us to develop capabilities that go well beyond the web mapping and related services we’re known for now – stay tuned!

Slashgeo: Will there be any impact on your relation with the Open Geospatial Consortium and your support for modern and efficient geospatial standards?

OpenGeo: Our greater independence and funding will enable us to be even more effective in working with the OGC. Our founder, Chris Holmes, was recently named to the OGC Board. We’re also founding members of LocationTech, with several other key OGC players, which is helping broaden adoption of location aware technologies that leverage geospatial standards.

Slashgeo: Any long term plans associated to this change that you'd like to share with our readers?

OpenGeo: Our goal remains the same: to build the highest quality software for location and mapping, available to all. This important step gives us a stronger base of resources to support the open source communities we work with. We remain committed to open source principles and look forward to continuing our develop the best geospatial tools while supporting the open source communities and our customers alike.

Mapping New York's Citi Bike Scheme
sur Google Maps Mania

My guess is that the most mapped data in the world over the last couple of months has been from New York's new Citi Bike scheme. Here's a little round-up of some of the maps created so far.

Let's start with the official Citi Bike Stations map. The Citi Bike Google Map shows the location of all the city's bike stations. If you select a station's map marker you can find out how many bikes are currently available and how many docking stations are free.

That's about it for this map, although the map does show planned bike stations, using yellow map markers. So you can at least see if a station is likely to open anywhere near you in the near future.

The CASA Global Bike Share Map is one of the better bike share maps. The map (using OpenStreetMap map tiles) allows users to mouse-over bike stations and view how many bikes and empty docking spaces are available. The markers are also color-coded to show at a glance which stations are more empty and which are more full.

The Global Bike Share Map includes an interesting feature that allows the user to animate through the last few days of activity at each bike station. It is fascinating to watch the bike station activity pick-up and die down through rush hour periods and through the night.

The Global Bike Share Map has the added bonus that you can view the same visualisations for many other city bike sharing schemes around the world.

The WNYC Bike Share Map doesn't do anything amazing. You can click on each station's marker and view how many bikes and how many empty docks are available. However I have to include it here because it uses the Google Maps API new map style - so it does look beautifully clean and fresh.

The Atlantic Wire has a near real-time Google Map that updates with the latest activity at all the city's bike stations. A few times a minute, the map checks the Citibike database and drops a marker on the map where there has been some activity.

Messages are also added below the map that report which stations have just seen a bike returned or borrowed.

If you want to join the biking crowd then you should check out this map of routes and tips to cycling in New York.

The New York Times' Your Biking Wisdom in Ten Words is a handy reader's guide to biking in the Big Apple. The map includes readers' tips on good and bad biking locations and a number of popular cycling routes, care of Strava users.

If all these Citi Bike maps have got you inspired you should get along to the City Bike Civic Hack Night on Wednesday June 26th. You should also check-out Citi Bike Stats, which has a lot of interesting graphs and charts using data from the Citi Bike scheme. There are no maps but there is a lot of lovely data.

Government Aid on Google Maps
sur Google Maps Mania

The Development Tracker provides detailed information on international development projects funded by the UK Government. The site includes a section entitled the 'Top 5 places we work'. This section includes Google Maps of five countries alongside details about the UK aid given to each country.

Interestingly each of the Google Maps includes a nice little reminder that maps are always political. The Development Tracker has felt the need to add a disclaimer to all of the Google Maps that reads, "Country borders do not necessarily reflect the UK Government's official position".

The Development Tracker also contains a prototype version of an API (application programming interface) enabling developers to retrieve the data in JSON format. There are also plans to open source the code for the Development Tracker, so that anyone can freely re-use or even contribute to the code.

Derrière le portail de la géomatique largement reconnu et utilisé par la communauté des géomaticiens francophones fonctionne une association loi 1901. Association pour laquelle l’équipe de quelques trente bénévoles, qui la compose et font vivre le portail, relance cette année un appel aux dons.

En effet, si les dépenses annuelles de l’association avoisinent 2 500 euros, dont l’essentiel est consacré à l’hébergement, les recettes peinent à équilibrer ce budget pourtant très limité.

L’essentiel des recettes est constitué des cotisations des membres comme l’indique le compte-rendu de la dernière assemblée générale.

C’est pourquoi l’association relance un appel aux dons. Celui qui avait eu lieu il y a un peu plus de quatre ans, avait permis de financer le nouvel hébergement rendu nécessaire par le succès de ce portail. Les dons reçus alors ont donc permis de gérer le portail et l’association au cours de ces dernières années.

Le petit coup de pouce que peuvent apporter les acteurs de la géomatique permettra de poursuivre les efforts entrepris : financer le serveur et la vie de l’association. Car GeoRezo représente une activité importante au service de la géomatique : 22 forums, plus de 200 000 messages, en moyenne 80 messages par jour, 7 blogs, 13 300 annonces job, 3 105 CV en base, des partenariats avec les associations et les médias du secteur, la présence à plusieurs événements éditeurs chaque année, et toute une communauté qui échange sur les forums, qui nourrit les pages wiki, qui consulte les offres d’emploi … L’espace de référence qui apporte chaque jour des informations et des ressources aux acteurs de la géomatique.

Rappelons que l’association est reconnue d’intérêt général. Vos dons ouvrent donc droit à déduction fiscale.

gvSIG Team: gvSIG 2.0: Biblioteca de símbolos “OCHA-Humanitarian”
sur Planet OSGeo

Comentabamos en un anterior post el uso cada vez más frecuente de gvSIG en el ámbito de la protección civil y la gestión de emergencias. A raíz de la publicación de la Biblioteca de símbolos “Emergency”, recibimos información por dos sitios distintos sobre la existencia de un juego de símbolos que sería muy interesante incorporar en gvSIG.

Se trata del conjunto de símbolos creado por la Oficina de Naciones Unidas para Coordinación de Asuntos Humanitarios (OCHA) para fines humanitarios, con el objetivo de ayudar a los trabajadores y voluntarios a presentar e interpretar la información sobre las emergencias y las crisis de forma rápida y sencilla.

Cuando ocurre un desastre, es vital que todos los diferentes organismos humanitarios y los trabajadores pueden obtener información precisa sobre las necesidades de las personas afectadas y las localizaciones y recursos disponibles para ayudarlos. Este conjunto de símbolos es, en cierto modo, el estándar de la simbología de emergencias.

Como comentaba nos llegó la información por dos vías distintas, una de ellas, un organismo de protección civil que nos comentaba que había tenido que pagar para poder incorporar esos símbolos en un SIG privativo de cuyo nombre no quiero acordarme. Y, por supuesto, comentamos lo importante y útil que sería disponer de estos símbolos en gvSIG. Dicho y hecho.

Hemos generado la biblioteca, incluyendo los símbolos con marco blanco y marco de color, y generando varias subcarpetas, primero por los colores utilizados habitualmente (blanco, azul, verde y rojo) y segundo por la temática. En definitiva, hemos mejorado lo que ese organismo tuvo que pagar por tener este conjunto de iconos disponibles en un SIG privativo, donde parece que (también en estos casos) el dinero está por encima de todo.

Son cientos de símbolos que gracias a las nuevas herramientas que trae gvSIG 2.0, hemos incorporado en unos pocos minutos en nuestro gvSIG.

Hemos complementado la biblioteca, como es habitual, con una serie de símbolos lineales y poligonales que pueden ser de utilidad para representar la gravedad de un determinado fenómeno e inspirados en distintos mapas realizados por organizaciones humanitarias.

Este paquete lo tenéis disponible desde el administrador de complementos (seleccionando la URL [downloads.gvsig.org] y buscando por “Tipos/symbols”) o directamente descargándoos el paquete desde aquí.

Esperamos que esta nueva biblioteca sea de utilidad y que, realmente, no sea necesario utilizarla en muchas ocasiones.

Day of CaringBig Blue Thread
sur Planet Geospatial - http://planetgs.com

Each year EPA Region 7 staff come together to make a valuable impact in the community. This special day is known as “Day of Caring.” This year marked the 19^th annual Day of Caring which took place on Saturday, June 1, 2013. Our volunteer team consisted of 17 people including staff, spouses and kids.

(Back Row, left-to-right): Toni Castro, Bob Wilson, Chris Lubbe, Dan Garvey, Jan Simpson, Fatimou Ndiaye, Marcus Rivas, LaTonya Sanders

(Front Row, left-to-right): Mary Peterson, Wendy Lubbe, Colleen Wilson, Shanice Castro, Steve Herndon, Kerry Herndon

Not Pictured: Karen Garvey, Jim Stevens, Paige Stevens

Special volunteers were the Lubbe twins, Caroline and Rose (pictured on front row)

Coordinated by the Heart of America United Way and the Heartland Combined Federal Campaign, Day of Caring is a community-wide service event that connects volunteers with nonprofit organizations to address social needs through special projects or events in the Kansas City metropolitan area.

EPA Region 7 has supported and participated in Day of Caring since the very beginning. Each year, our staff look forward to spending a day together outside of the office, in the community, cleaning, painting, gardening, and helping with other projects at nonprofit organizations. At the end of the day, it always feels great giving of ourselves to these organizations that make huge impacts in the communities that we live in and serve.

The EPA Region 7 team volunteered for Catholic Charities of Northeast Kansas at their Central Avenue facility in Kansas City, Kansas. On the surface, we knew of some of the services and programs that Catholic Charities provided. But, we learned so much more about the organization and their impact in the community, helping families and individuals in need, and their extensive programs to help refugees. The EPA Region 7 volunteer team worked on five projects.

Bagging Canned Goods for Distribution

Catholic Charities has several programs where they distribute donated food to homebound individuals. Volunteers bagged canned goods for distribution.

Restocking the Food Pantry

Catholic Charities has a food pantry where families and individuals in need can “shop” for grocery and personal items. Volunteers restocked the shelves in the food pantry with donated items.

Organizing the Clothing Closet

Catholic Charities has a clothing closet where families and individuals in need can “shop” for clothing, shoes and other items. Volunteers helped to sort and hang up clothes and organize the closet.

Beautification of the Garden

The Catholic Charities Central Avenue location has a beautiful garden and picnic area. Volunteers helped to weed, clean up and plant flowers and shrubbery.

Grounds Cleanup

Volunteers helped to clean up around the parking area by weeding and raking leaves and debris.

Événement géomatique en octobre 2013
sur Blogue de la géomatique du MSP

En octobre 2013, deux événements géomatique auront lieu à Montréal.

1) Le Défi GéoHack de Montréal se veut un événement ponctuel qui aura lieu le 2 octobre 2013 à Montréal. Il est dérivé des « hackathons », offrira la possibilité à des «Donneurs d’ouvrages» en géomatique d’élaborer des défis réels pour des développeurs. Différents thèmes pourront être envisagés: Santé et sécurité publique, culture, transport, environnement, etc. Le hackathon se tenant un jour de semaine (mercredi le 2 octobre en marge du Colloque Géomatique 2013) une bourse financée par les « Donneurs d’ouvrages » et les commanditaires, sera remise à tous les développeurs sélectionnés. De plus, plusieurs prix récompensant les meilleures réalisations seront remises par un jury. Ce projet a été retenu par l’Assemblée plénière de la Table de concertation sur l’ouverture des données (TCDO) de la ville de Montréal, le 5 juin 2013, comme une des cibles pour mobiliser les citoyens et les employés municipaux à l’ouverture de données.

Walking Routes with Suggested Pit Stops
sur Google Maps Mania

StreetScout is a handy application for finding places to stop along a walking route.

You tell StreetScout what you're looking for and where you're going, and it'll give you advice about where to stop on the way. Simply add a starting point and a destination and StreetScout will display the best walking route on a Google Map.

If you fancy a coffee or maybe something to eat, or even a new pair of jeans then you just need to tell StreetScout what you are looking for. Places to stop along your route are also added to the map. Click on any of the suggested stops on the route and you can even view how far off your route the location is.

Infoboxes for Native Windows Store AppsMaps Blog

sur Planet Geospatial - http://planetgs.com

Recently there has been a number of requests for information on how to create infoboxes using the Bing Maps Native control. Many developers who have used our JavaScript controls are used to an infobox control being available out of the box and are a bit surprised that there isn’t one in the Native control. This wasn’t an oversight, but really not needed. With the Native control, we have the ability to overlay user controls directly on top of the map and tie them to a location on the map. This means that rather than being restricted to having to use an infobox control that looks and feels the way we think it should, you have the ability to create an infobox that looks and feels how you want.

In this blog post we will take a look at how to create a simple infobox control. To optimize this application, we will use a common method of having one Infobox control which we will reuse and update rather than creating an infobox for each pushpin we create. This will drastically reduce the number of objects your application will need to render and keep track of. This same approach is recommended when using the JavaScript control as well. If using JavaScript, take a look at this blog post.

Creating the View

To start off, create a Blank Windows Store project in Visual Studio called BingMaps_Native_Infobox and add a reference to the Bing Maps SDK. If you are not familiar with how to do this, take a look at the Getting started with Bing Maps Windows Store Apps (Native) blog post.

Once your project is created, open up the MainPage.xaml file and add a reference to the Bing Maps SDK and add a map to the main Grid. Inside of the map, we will add two MapLayers and give the first layer a name of DataLayer. We will use this layer to add our pushpins to. We will put the infobox in the second layer and this will ensure that the infobox always appears above the data layer. For the infobox itself, we will use a Grid control and add some Textboxes for Title and Description information. We will also add a close button to the infobox. Putting this together, your XAML should look like this:

Page

    x:Class="BingMaps_Infoboxes_Native.MainPage"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                m:MapLayer Name="DataLayer"/>



                

                m:MapLayer>

                    Grid x:Name="Infobox" Visibility="Collapsed" Margin="0,-115,-15,0">

                                Button Content="X" Tapped="CloseInfobox_Tapped" HorizontalAlignment="Right" VerticalAlignment="Top"/>

                m:MapLayer>

            m:Map.Children>

        m:Map>

    Grid>

Page>

Adding the Application Logic

If you try running the application now, an error will be thrown as we haven’t defined the CloseInfobox_Tapped event handler. To fix this, open the MainPage.xaml.cs file and add the following event handler:

private void CloseInfobox_Tapped(object sender, Windows.UI.Xaml.Input.TappedRoutedEventArgs e)

{

    Infobox.Visibility = Visibility.Collapsed;

}

Next, we need to add some pushpins to the map. To do this, we will create a reusable function that takes in a Location, title, description and a reference to a MapLayer to add the pushpin to. When we create the pushpin we will store the title and description inside the Tag property of the pushpin. We will then add a Tapped event which we will use to open our infobox. Finally, we will add the pushpin to the layer. Add the following code to your application:

public void AddPushpin(Location latlong, string title, string description, MapLayer layer)

{

    Pushpin p = new Pushpin()

    {

        Tag = new Metadata()

        {

            Title = title,

            Description = description

        }

    };



    MapLayer.SetPosition(p, latlong);



    p.Tapped += PinTapped;



    layer.Children.Add(p);

}



public class Metadata

{

    public string Title { get; set; }

    public string Description { get; set; }

}

Now we will create the PinTapped event handler. When the user taps the pushpin, we will take the metadata we stored in the pushpin and bind it to the Infobox. We will then make the infobox visibility and then use the MapLayer to set the position of the infobox.

private void PinTapped(object sender, Windows.UI.Xaml.Input.TappedRoutedEventArgs e)

{

    Pushpin p = sender as Pushpin;

    Metadata m = (Metadata)p.Tag;



    //Ensure there is content to be displayed before modifying the infobox control

    if (!String.IsNullOrEmpty(m.Title) || !String.IsNullOrEmpty(m.Description))

    {

        Infobox.DataContext = m;



        Infobox.Visibility = Visibility.Visible;



        MapLayer.SetPosition(Infobox, MapLayer.GetPosition(p));

    }

    else

    {

        Infobox.Visibility = Visibility.Collapsed;

    }

}

We now have all the code we need to create pushpins that open up an Infobox when tapped. All we need to do now is create some pushpins. To do this, update the constructor to look like this:

public MainPage()

{

    this.InitializeComponent();



    AddPushpin(new Location(47.6035, -122.3294), "Seattle", "Seattle is in the state of Washington. ", DataLayer);



    AddPushpin(new Location(51.5063, -0.1271), "London", "London is the capital city of England and the United Kingdom, and the largest city in the United Kingdom.", DataLayer);

}

If you run the application, you will see two pushpins on the map. If you tap on one, the Infobox will appear with the relevant information for that pushpin and look something like this:

You can take this a step further and create a custom UserControl that has a lot more advanced features. In the end you simply just need to add it to a MapLayer and set its position.

Landsat 8 imagery of Elbe river floodingBetween the Poles
sur Planet Geospatial - http://planetgs.com

There's a very interesting comparison from the NASA Earth Obervatory of Landat 8 imagery showing flooding on the Elbe in Germany.

Image 1 is a natural-color, pan-sharpened image of the Elbe River near Wittenberg, Germany, obtained by Landsat 8 on May 6, 2013. Image 2 is from June 7, 2013, which shows flooding of the Elbe.

If you look closely at Image 1 you can make out a jagged pattern along the river which is often a symptom of a processing error. A recent blog post from the NASA Earth Obveratory explains that in this case this is not a processing artifact, but real structures along the river which they were able to verify by looking at among other things high resolution imagery on Google Earth.

North American BIM adoption reached 71% in 2012Between the Poles
sur Planet Geospatial - http://planetgs.com
Over the past five years the processes and technologies of building information modeling (BIM) have been transforming the construction industry. First architects and to a lesser extent engineers, and now increasingly contractors are adopting BIM to reduce risk and increase margins. There are signs that owners are also realizing benefits from BIM and that operations and maintenance which are responsible for about 80% of a building's lifetime cost may be the part of the lifecycle of a building where BIM provides the largest benefits. Typical applications where BIM has been applied include automating clash detection, quantity takeoff. and change propagation; reducing data redundancy; improving collaboration among design teams; construction scheduling; automating bill of materials and job costing; and using 3D visualization to involve non-technical stakeholders in the design process.

BIM and Geospatial

Several years ago, in an award winning paper at a conference organised by Britain’s Association for Geographic Information (AGI), Ann Kemp, then head of GIS at Atkins Global, the design and engineering firm, asked the question ‘BIM isn’t geospatial -- or is it?’ and then argued that integration of geospatial and BIM was essential to address the challenges of the 21st century. Kemp wasn’t the first one to speak on this. The need to integrate geospatial and BIM has been gaining traction for some time now and government mandated energy efficiency for buildings is a major driver of BIM/geospatial convergence.

BIM in the construction industry

McGraw-Hill Construction has conducted a survey of the use of BIM processes and technologies in the construction industry in 2007, 2009 and 2012. The most recent report called "The Business Value of BIM in North America: 2012" involved an online survey that was completed by 582 respondents from North America in August to September, 2012. The companies invited to participate came from McGraw-Hill Construction's own databases as well as from industry associations including AGC, AIA, ASA, ASCE, CMAA, COAA, DBIA, NIBS, SMACNA & SMPS.

Workng Definition of BIM

In the survey the working defintion of “BIM” that was "broadly the creation and use of digital models and related collaborative processes between companies to leverage the value of the models." The definition was intended to differentiate BIM from CAD. It also was intended to be inclusive, to include users not just model authors. Respondents were classified as BIM users or non-users. By non-users was meant "not engaging with BIM at all”. BIM users included a broad range of users including model authors and users who used models for analysis or simulation, but did not author them.

Repondents' companies were classified into five categories, architects (building and interior), engineers (structural, mechanical, and others), contractors (general and trade), owners, and others. Of the 582 respondents, the company breakdown was
- 7 % owners
- 39% contractors - broad array of contractors
- 21% engineers - mostly structural and mechanical
- 33% architects - mostly building architects
Key trends in BIM in the construction industry

Adoption

Overall Adoption of BIM has increased from 17% in 2007 to 71% in 2012, representing 45% growth over the last 3 years. In 2012 adoption by all categories of company increased, but contractors in particular saw increased adoption (74%) exceeding that of architects (70%).

Expertise level and experience

The percentage of very heavy users increased from 27% in 2009 to 39% in 2012, and is projected to increase to 58% by 2014. The percentage of very heavy users is forecasted to double over the next 5 years. The percentage of highly experienced users (5 or more years) more than doubled from 2009 to 2012.

Perceived Return on investment (ROI)

Most repondents reported a positive return on investment in BIM with owners, contractors and archtects reporting the highest proportion of positive ROI.
- Owners 67%
- Contractors 74%
- Engineers 37%
- Architects 65%
A significant proportion of contractors (7%) and architects (8%) report an ROI of over 100%.

Internal benefits of BIM

The most important internal benefits of adopting BIM reported by the respondents were
- Reduced errors and omissions in documents
- Marketing new business to new clients
- Maintaining repeat business with past clients
- Reducing rework
- Offering new services
- Reducing cycle time of specific workflows
- Reducing overall project duration
- Increased profits
- Reduced construction cost
- Fewer claims/litigation
- Recruting and retention of staff
In 2012 the largest increases over 2009 were Increased profits, maintaining clients, reducing project duration and fewer claims.

BIM for operations and maintenance

A small but significant percentage of owners are using models for building system operation analysis, maintenance scheduling, asset and space management.

Related to this, about 60% of contractors report medium to high demand from owners for as-built record models.

La cartographie des surfaces de vente
sur geomarketing.ca

On utilise souvent la géolocalisation pour établir la provenance de la clientèle. En couplant ces informations à des bases de données externes, elles permettent d’en connaître davantage sur le profil des consommateurs. Saviez-vous que vous pouvez aussi utiliser la géolocalisation intérieure afin d’optimiser votre marchandisage?

À l’aide de différentes techniques de captation de l’information (code barre, RFID, video, etc.), vous serez en mesure de produire la cartographie des déplacements des clients en magasin. Vous serez ainsi en mesure de déterminer quels sont les endroits les plus et les moins fréquentés de votre surface de vente.

En fonction des zones produites (zone « chaude » vs zone « froide ») vous pourrez adapter la configuration de votre magasin en plaçant les produits les plus rentables ou les plus en demande aux endroits stratégiques pour favoriser des ventes accrues. Au contraire, vous aurez tout avantage à placer les produits spécifiques et/ou nécessaires dans les zones les moins spontanément fréquentées (généralement dans le fond du commerce – pensez au lait à l’épicerie!) mais qui vont naturellement générer des ventes.

gvSIG Team: gvSIG 2.0: Thematic Maps II
sur Planet OSGeo

At this new post of the “Thematic maps” series we will see how to generate a package for sharing a thematic map with other users.

In the previous post we had generated our first thematic map, that will have been saved by default in home/usuario/gvSIG/plugins/org.gvsig.educa.thematicmap.app.viewer/thematicMaps.

At this way, in any gvSIG project we can see a “Thematic map” that has been created already. We only have to press “New” on the “Thematic Map” document from the “Project Manager”. This will open a window with a list of all the thematic maps available. It will allow us to access to the thematic maps from any gvSIG project, but not for sharing the thematic maps wirh other users. To share the thematic map we will have to generate a package.

Firstly we must know that when a thematic map package is generated we are going to get an install file from the add-ons manager of any gvSIG 2.0. What does this package contain? It contains the cartography (the files), the legends, the labelling, the maximum and minimum scale of viewing of each layer, the background colour…, it contains the complete thematic map ready to be shared.

The process is as easy as selecting the option in the corresponding menu: Thematic Map/Generate package.

A window will be opened, where we will have to indicate the folder where the package will be saved (the name will be created automatically). In our case, it has generated a package called ThematicMap-World_Countries-1-BN1.gvspkg.

Ready to be sent.

If you want to test it, this package and some other ones are available at the outreach website, in a section the objective of which is to be a catalogue with maps that are interesting for the users of this gvSIG extension and gvSIG Educa: [outreach.gvsig.org]

By the way, if you want to contribute to feed this section, you only have to follow these instructions: [outreach.gvsig.org]

If you are the recipient of a Thematic map package and you are interested in the inverse process, converting the Thematic Map in a View (for changing its legend, edit it…) you only have to select the menu option: Thematic Map/Export to View

It will ask us for a file where the files will be saved (important: it must be empty), and it automatically will create the view equivalent to that thematic map.

That’s all for today… At the next post of this series we will see how to generate a package from a group of packages, that means, how to share groups of thematic maps in an only file.

Cumulative smart grid revenue 2013 to 2020 projected to reach $461 billionBetween the Poles
sur Planet Geospatial - http://planetgs.com

I blogged recently about a report from Memoori, a UK research firm, called “The Smart Grid Business 2012 to 2017”, which analyzes global smart grid-related sales. Its research has identified some interesting trends in the current smart grid market. In the last 3 years Memoori estimates that the world smart grid-related sales has more than doubled from $16.2 billion in 2010 to $36.5 in 2012. 40% of this is smart meters

A recent report from Navigant Research says that the global smart grid technologies market amounted to more than $33 billion in revenue in 2012. Navigant is projecting that the market for smart grid technologies will reach $73 billion in annual revenue by the end of 2020. The cumulative total for 2013 to 2020 is projected to reach totaling $461 billion.

The report identified five segments: transmission upgrades, substation automation, distribution automation, smart grid information and operations technology and smart metering. According to Navigant the most capital-intensive segment is transmission, which is estimated to contribute nearly $250 billion in revenue from 2013 to 2020, more than half the cumulative total for the smart grid technology market.

According to a report by Innovation Observatory 80 % of the worldwide investment in electricity smart grids by 2030 will be made by 10 countries. Over the next five years, it is projected that the United States will dominate global capital expenditure, but China is projected to pass the U.S. in 2016. For the entire period through 2030, the top spending countires will be China (US$99 billion by 2030), United States (US$60 billion by 2030), India, France, Germany, Brazil, Spain, United Kingdom, Japan and Korea.

SourcePole: FOSSGIS 2013: Performance optimised wms services with QGIS server
sur Planet OSGeo

Performance is usually a top priority for a WMS service. A recent talk at the FOSSGIS (held by Sourcepole) shows what a WMS administrator can do to optimise QGIS server performance. Finally, the performance of QGIS server is compared with UMN mapserver in two production scenarios.

Slides from FOSSGIS 2013 in Rapperswil (in german).

Welcome OpenCage Data as new #geomob sponsor#geomob London
sur Planet Geospatial - http://planetgs.com

Fellow geomobsters,

I’m delighted to announce our new sponsor OpenCage Data.

OpenCage helps organisations make use of OpenStreetMap data by providing a simple and affordable data extraction service. In their own words “OpenStreetMap data when you want it, in the format you want it”. If you want to avoid the yak-shaving involved in ongoing data extraction give OpenCage a try.

This week we’ll be posting the lineup for our next event which will be on 11th of July at 18:30 at Google’s Old Street Campus. Please register on the event page on Lanyrd so we can get a sense of the numbers. We look forward to seeing everyone there, the post-talk geobeers will be on OpenCage Data and our other sponsor knowwhere consulting.

Exploring the Data Behind Maps
sur Google Maps Mania

The UK's Liberal Democrats Party has created a Google Map that purportedly shows how the political party has created 1 million private sector jobs whilst it has been the minority partner in the UK's coalition government.

What's happening in your area? shows locations presumably where the Liberal Democrats believe jobs have been created. The map is obviously contentious. I've been trying to dig around employment rate statistics and the most optimistic statistic I can find suggests that the employment rate in the UK has grown by about half a million during the present government. However even if the employment rate has risen by 1 million the implication of the map is that all these jobs are the direct result of the Liberal Democrats' 'job creation' schemes.

OUseful.Info has been digging around a little in the data behind the map. His post Critiquing Data Stories: Working LibDems Job Creation Data Map with OpenRefine is a very interesting account of how to access the data behind the map and how OpenRefine can then be used to start exploring the data. In a second post, Do Road Improvements Really Create Jobs, he then explores a little deeper into some of the claims made by the map.

SourcePole: FOSSGIS 2013: Qualitätssicherung von Geodaten auf der Basis von Web Processing Services (WPS)
sur Planet OSGeo

Bevor neue Daten in eine Geodaten-Infrastruktur überführt werden, müssen sie Qualitätssicherungs-Verfahren durchlaufen. Diese Prozesse können sowohl generisch, als auch speziell für ein bestimmtes Datum konfektioniert sein. Um Sicher zu stellen, dass diese Prozesse langlebig und verfügbar sind, bietet es sich an OGC-Konforme Services zu diesem Zweck zu nutzen. Deshalb werden im Vortrag die Vor- und Nachteile OGC-Konformer Web Processing Services (WPS) als Basis der Qualitätssicherung von Geodaten diskutiert.

La carte du monde de la production cinématographique
sur Une carte du monde.

En France, notre production cinématographique est forte. Cela vient de notre histoire, bien entendu, mais aussi des subventions du CNC. Chaque place de cinéma achetée (pour un film français ou étranger) finance une partie des productions nationales.

Nous connaissons évidemment les productions américaines, et voyons de temps en temps sur nos écrans quelques films japonais (horreur), espagnols (angoisse) ou anglais (comédie), mais saviez-vous que le plus grand producteur de films au monde était l’Inde ?

Saviez vous que le Nigéria en produisait presqu’autant que le continent américain entier? A la différence près que la production nigériane présente 20 millions de $ alors que celle des Etats-Unis dépasse les 10 millards de $.

Connaissiez vous l’importance de la production russe et sud-coréenne ?
