The Many Faces of Google Maps
sur Google Maps Mania

Pareidolia is a psychological phenomenon that leads us to see familiar objects in random patterns. For example, when we look at aerial imagery of the Earth we might think we recognise faces in the topography.

onformative has created a computer program, called GoogleFaces, that scans Google Maps satellite imagery looking for patterns that humans might believe are human faces. GoogleFaces scans through one satellite image after another on Google Maps, sequentially along the latitude and longitude of the globe. After scanning around the world it then switches to the next zoom level and starts all over again.

As it scans each satellite imagery the GoogleFaces face detection algorithm records the latitude and longitude of any 'faces' it finds. The onformative website has a few examples of the faces already found on Google Maps, including the one above, found in the satellite imagery of Russia.

Reusing integrated geospatial and design data across the construction lifecyleBetween the Poles
sur Planet Geospatial - http://planetgs.com
One of the most important things that impressed me at the Geospatial World Forum 2013 (GWF 2013) conference in Rotterdam is the degree to which in the Netherlands that building information modeling (BIM) and geospatial are perceived to be tightly linked. In my previous post I gave an overview of a presentation by Bram Mommers, who works for the large private engineering company ARCADIS, on why integrating geospatial into the construction process is important.

Jaap Bakkers, who is with the Rijkswaterstaat, the national water company in the Netherlands, presented more details about the Concept Library (CB-NL) initiative.

It is supported by the Dutch Council on Building Information (BIR), which is a joint industry and government council created to foster the development of building information modeling (BIM) in the Netherlands. It includes government agencies such as Rijkswaterstaat, private construction contractors, and engineering and architural firms. Government funds it, but most of its expertise is seconded from industry.

Construction processes in the Netherlands

In the Netherlands many government projects are private-public partnerships (P3), where a private sector firm or consortium is responsible for the design-build-finance-maintain phases of the lifecycle and the government as the owner is responsible for operation.

Many AEC firms are adopting BIM because it is cheaper, reduces risk of budget, schedule overruns, and results in fewer change orders. They may be motivated to adopt BIM to increase their margin or because they are required to by the owner, which is often a governmental organization such as the Rijkswaterstaat. Once construction is complete, at commissioning, the owner is handed a large volume of facilities data and as-builts. But this data is often unusable by the owner because it is incompatible or non-interoperable with the owner's asset management, GIS, and other systems. This is the primary objective of the Concept Library (CB-NL), to create standards that enable re-use of design and construction data for operations. This is one example of the data impedance problem, where at every handover, design to construction, construction to operations, data is lost and has to be recreated.

Geospatial in the construction process

Marcel Reuvers, Manager of Geo-standards at Geonovum, gave an overview of some the critical roles that geospatial plays on the construction lifecycle.
- Planning / preparation phase
- Asset management / maintenance
- Managing as-builts
I would add sustainable design which always requires geospatial information about local prevailing weather pattern and the location and orientation of neighbouring structures for right to light, wind, solar heating, natural lighting, solar PV generation potential, and other analysis.

I blogged previously about some fundamental changes to the construction process that will make geospatial central to the construction process. What has been proposed is that a post-construction survey would become the critical source of reliable asset information in the form of a 3D intelligent model which would be maintained in a geospatially-enabled asset database. When a new project is initiated, 80-90% of the necessary information would already available in the database making a complete resurvey, as is the current construction practice, unnecessary. All that is required before design can begin is minimal due diligence to validate the as-builts. The new process also implies that there is a reliable geospatially-enabled asset database that is maintained thoughout the operations and maintenance phase of the lifecycle.

Concept Library (CB-NL)

In the Netherlands there is already a standard decomposition for buildings called COINS. The idea is to build on this to create a general approach for decomposing infrastructure as well as buildings and that it suffiiciently general to include geospatial.

The Concept Library is intended to map different terminology across domains: design, engineering, architecture, construction, asset management, facilities manmagement,and geospatial. For example, it interelates terms like arch bridge, rail bridge, spanning structure, viaduct, and crossing, each of which may be used by a different domain to refer to the same structure. The business benefit is that it would reduce the data impedance problem, where at every handover in the construction lifecycle, designer to contractor or contractor to owner, data is lost and has to be recreated.

The vision is that the Concept Library is an open database based on a standard ontology that is searchable and has an open API so that vendors such as Autodesk, Bentley or ESRI can develop interfaces to it for their products.

CB=NL and geospatial

CB-NL was initially focused on BIM, but is being extended to include geospatial. CB-NL enables designers, contractors, asset managers and GIS staff to share a common dataset. It also makes it possible to automate the process of populating asset and facilities management application and GIS databases for the operations and maintenance phase of the lifecycle.

Concept Library (CB-NL)

A two year project to develop the Concept Library has just been initiated, in January 2013, which is supported by a large number of government and private organizations. It is using the OWL ontology language, which has been endorsed by the W3C. It uses tools and constructs from buildingSmart's Semantic Constructs for inputting and editing semantic content. Real world pilots, for example, a Rijkswaterstaat water services project and the Schipol, Amsterdam, Almere ring road project, will be used to demnstrate the practicality of the approach.

According to Marcel Reuvers, there are a number of standards that relate to the CB-NL project from a number of standards bodies including the OGC, buildingSmart, ISO/TC211, and LandXML. Jaap Bakker said that the project team has been in touch wth the Open Geospatial Consortium (OGC) in additon to the buildingSmart Alliance about the CB-NL project.

Companies Near Me is a Google Map of tech companies in the San Francisco Bay Area.

The map includes options to filter the companies displayed on the map by location and by sector. The map is primarily focused on the San Francisco Bay Area but the developers say that they have plans to expand the site to include other tech hubs such as New York, Los Angeles and Boston.

Made in NI is a Google Map of Northern Ireland's start-up's, tech companies and co-working spaces.

Tech maps for individual cities are now being created for many locations around the world. However we don't often see attempts to map entire countries / provinces. Made in NI is a nice attempt to map all of Northern Ireland's burgeoning technology companies.

As well as mapping individual companies, Made in NI also maps wi-fi spots, code clubs and learning spaces.

Welcome To The United States; A Cold War Tourist Map For Soviet VisitorsMostly Maps
sur Planet Geospatial - http://planetgs.com

In the mid 1950s America and Russia were in the middle of the game of oneupmanship, with added nuclear weapons, that was the Cold War. Despite the uneasy detente between the two countries, if you were one of an elite group of Soviet citizens you were actually able to visit the United States. But not all of it. Large swathes of the US were closed to prospective Soviet tourists.

What makes this map interesting is not so much the slice of relatively recent world history that it portrays but more of the questions it poses. What were the criteria that were used to determine where a Cold War era Soviet visitor could and couldn’t go?

You can make some educated guesses. It’s not unreasonable to assume that major ports, coastlines, industrial areas and military and weapons areas were off limits. But that doesn’t cover the full scope of the open and closed areas.

Over at BoingBoing, there’s speculation that this was as much a tit-for-tat set of restrictions as it was a set of restrictions based on what the US Government didn’t want Soviets to see. As Cold War era historian Audra Wolfe, the author of the Slate article on this map, notes

The main premise is ‘strict reciprocity’. X% of Soviet coasts are off-limits, therefore X% of US coasts are off-limits, too.

gvSIG Team: gvSIG 2.0: Scripting, exploit your gvSIG (III): Generate a polygon from a course
sur Planet OSGeo
Some time ago a friend of the project, Gustavo Agüero, published a post on his blog in which he explained how gvSIG generate a polygon from a bearing (or route or course). We found a very interesting exercise and with its help we implemented a script to undertake the same steps in gvSIG 2.0. The result is explained in this post.

We want to clarify that all the merit of this exercise is to Gustavo and the errors are because of our ignorance and for not properly follow his instructions. If you see some error, please, comment it and we will correct it

We start with a bearing or course that presents the data to the following structure LINE, AZIMUT, DISTANCE, being AZIMUT the angle direction in the sense counted clockwise from the geographic north (download rumbo.jpg).

The first thing to do is to save this file to a format that would be able to read from a script, this file we have created is a csv file that we named rumbo.csv (download rumbo.csv).

Once we have our file we have to think what we need to get its content into a shapefile. Obviously we’ll need a shapefile where to save the results and we’ll need to create the features to represent the data for including them on the shapefile. To create these features we’ll need to transform the polar coordinates (azimuth, distance) in rectangular coordinates (X, Y).

Some comments on that: Gustavo in his post recommend to make a representation of the data. This was very helpful to us.

In the script we will create a LINE shapefile and another one for POLYGONS. In the LINE type, we will keep heading data, data from coordinates transformation, and the resulting coordinates. In the POLYGONS shapefile will keep an identifier of the feature and a text field.

We start from a desktop gvSIG 2.0 (in my case I’ve used is build 2060 RC1) with the latest version of the scripting extension installed (currently the number 36).

Once we open the script editor (menu bar Tools / Scripting / Scripting Composer) we create a new script and start to write our script.

The first thing we’re going to do is to create the output layers using the function createShape from the gvsig module. The syntax of this function tells us that you need a data definition for the features, a route that is the place where to store the shapefile we are acreating, the projection of the shapefile, and the type of geometry that will contain. The definition of the data will be created using the function createSchema from the same gvsig module.

The source code, including comment would be:
```
import gvsig
import geom

def main():

'''
Create a polygon layer with the following data model:
    - 'ID', Integer
    - 'OBSERVACIONES', string
    - 'GEOMETRY', Geometry

Create a line layer with the following data model:
    - "ID", Integer
    - "LINEA", string
    - "GRADOS", long
    - "MINUTOS",long
    - "DISTANCIA", double
    - "RADIAN", double
    - "X", double
    - "Y", double
    - "GEOMETRY", Geometry            
'''

#Set up the projection, it is the same for both layers
CRS="EPSG:32617"

#Create the object that represent the data model for the polygonal shapefile
schema_poligonos = gvsig.createSchema() 

#Insert the filed from the data model
schema_poligonos.append('ID','INTEGER', size=7, default=0) 
schema_poligonos.append('OBSERVACIONES','STRING', size=200, default='Sin modificar') 
schema_poligonos.append('GEOMETRY', 'GEOMETRY')

#Set up the layer path. Remember changing it!!!
ruta='/tmp/rumbo-poligonos.shp'

#Create the shapefile
shape_poligonos = gvsig.createShape(
        schema_poligonos, 
        ruta,
        CRS=CRS,
        geometryType=geom.SURFACE
    )

#Create the line shapefile

#Create the object that represent the data model for the line shapefile
schema_lineas = gvsig.createSchema() 

#Insert the field from the data model
schema_lineas.append('ID','INTEGER', size=7, default=0) 
schema_lineas.append('LINEA','STRING',size=50,default='')
schema_lineas.append('GRADOS','LONG', size=7, default=0) 
schema_lineas.append('MINUTOS','LONG', size=7, default=0)
schema_lineas.append('SEGUNDOS','LONG', size=7, default=0) 
schema_lineas.append('DISTANCIA','DOUBLE', size=20, default=0.0, precision=6) 
schema_lineas.append('RADIAN','DOUBLE', size=20, default=0.0, precision=6) 
schema_lineas.append('X','DOUBLE', size=20, default=0.0, precision=6) 
schema_lineas.append('Y','DOUBLE', size=20, default=0.0, precision=6) 
schema_lineas.append('GEOMETRY', 'GEOMETRY')

#Set up the layer path. Remember changing it!!
ruta='/tmp/rumbo-lineas.shp'

#Create the shapefile
shape_line = gvsig.createShape(
    schema_lineas, 
    ruta,
    CRS=CRS,
    geometryType=geom.MULTILINE
)
```
Ok, we already have our output layers, now we are going to see how to get the data from csv file we created. Python has a module that allows csv csv file handling very comfortable ( python csv ). The source code for reading the csv file would be:
```
import csv
import os.path

#Set up the layer path for the CSV file. Remember changing it!!!
csv_file = '/tmp/rumbo.csv'

#Check that the file exists on the provided path
if not os.path.exists(csv_file):
  print "Error, el archivo no existe"
  return

#Open the file on read only mode
input = open(csv_file,'r')

#Create a reader object from the CSV module
reader = csv.reader(input)

#Read the file
for row in reader:
    #Print the line
    print ', '.join(row)
```
We already know how to create shapefiles and read csv files, the next step would be to create the features, so we must transform the polar coordinates to rectangular and it is at this point that for me things get a little dark so forgive the errors that you can find.
To make the coordinate transformation we’ll convert the decimal angle in radian angle. Gustavo in his post how to generate a polygonal (in Spanish) between the files to download you can find a PDF that provides an explanation of the calculations he made, if anybody has doubts I recommend to read it. I only want to clarify that we ‘ll use the python module python math to use math functions sine and cosine, needed to perform the transformation. In addition, our course uses relative coordinates, so we need a starting point and the code to calculate the new coordinates from the above ones. Our starting point is ( X= 361820.959424, Y = 1107908.627000). The source code would be:
```
"""
Convert decimal degrees, minutes, seconds to radian
"""
import math
#Define the “pi” value
PI = 3.1415926

x_ant = 361820.959424
y_ant = 1107908.627000

#Apply the equation and obtain the angle in radians
angulo = (degrees+(minutes/60.0)+(seconds/3600.0))*PI/180.0

#Convert the polar coordinates into rectangular ones

x_new = radio * math.sin(angulo)
y_new = radio * math.cos(angulo)

#Add relative coordinates values to get the next coordinate
x = x_new + x_ant
y = y_new + y_ant
```
The last piece of our puzzle is to learn how to create the features and their geometries. The layers that we created earlier shape_line and shape_polygons have a method called append that allows us to add the features to the layer. This method accepts a dictionary,
python dict that uses as key fields the ones we defined in the data structure of the layer (defined when we created it). The values are the ones that should have the feature. The geometries will be created using the geometric module geom from the scripting extension, in particular the createGeometry function, that needs the type of geometry to be created and the dimensions of the geometry. The code that we could use is:
```
geometry_multiline = geom.createGeometry(MULTILINE, D2)

values = dict()
values["ID"] = id #Calculated field for the registered number
values["LINEA"] = linea_id #First data of the course
values["GRADOS"] = grados #decimal degrees from the course
values["MINUTOS"] = minutos #decimal minutes from the course
values["SEGUNDOS"] = segundos #decimal seconds from the course
values["DISTANCIA"] = radio #Distance from the course
values["RADIAN"] = angulo #Radian angle calculated
values["X"] = x #X coordinate calculated
values["Y"] = y #Y coordinate calculated

shape_line.append(values)
```
At this point we have seen everything needed to get what we want from our original course, we only need to assemble the puzzle and the final result would be this:

Polygon generated from the course

The final source code can be downloaded from here .

We hope you enjoy that exercise as much as I do.

See you next time!

Mapping Newspaper Text
sur Google Maps Mania

Mapping Texts is a Google Map from Stanford University that plots the language patterns embedded in 232,567 pages of historical Texas newspaper.

The app analyses the language patterns found in Texas newspapers from 1829-2008. Using a timeline slider tool you can select any date range and, using the map, you can select from a number of locations in Texas. The results of each search are then displayed below the map.

The results show the most common words (word counts), named entities (people, places, etc), and highly correlated words (topic models). The results can be viewed in list view or you can view the results as a word cloud.

What did teenagers do before cell phones, video games and the internet?

I know - they made maps.

At least that what Frances Alsop Henshaw was doing in the 1820's. Henshaw's 'Book of Penmanship Executed at the Middlebury Female Academy' contains a number of hand-drawn maps of nineteenth century America.

Neatline.org has used its map timeline tool to create an interactive presentation of Henshaw's beautiful hand-drawn maps. 'Inventing the Map': Frances Henshaw’s Book of Penmanship uses the Google Maps API to overlay Henshaw's nineteenth century maps on today's map of America.

Integrating geospatial into construction: the challengeBetween the Poles
sur Planet Geospatial - http://planetgs.com
I spent most of last week at the Geospatial World Forum 2013 (GWF 2013) in Rotterdam, which was an amazing event, because of its focus on monetizing geospatial value in vertical industries, Industries for which there were symposia at GWF 2013 include construction and infrastructure, electic power and gas, mining and exploration, water as a resource, water distribution management, and agriculture in addition to more traditional sectors such as land management, photogrammetry and the environment.

I spent most of my time in Construction and Infrastructure sessions. There were many absolutely fascinating pesentation on the applicaton of geospatial technology in this sector. Among the most far-reaching in terms of potential impacts were three or four talks that explicitly addressed the challenge of finding a practical way to integrate geospatial into construction processes.

Value of geospatial information

To put this in context, there is a strong drive in the Netherlands to integrate geospatial information into govenrment organizations. Geonovum is leading the charge in this area. By way of motivation there is a very interesting cost-benefit analysis in the context of the European INSPIRE initiaive by Ecorys and Grontmij in November 2009. The scope of study was the cost and benefits of the collection, maintenance and dissimilation of geographic information, but just within governmental organizations in the Netherlands. The study did not attempt to estimate the value of geospatial information to society as a whole. It concluded that over 15 years, the total net benefit to government organizations in the Netherlands would be € 34 million (Ralf Duinmeijer, Joulz ICT private communication).

Cost of poor interoperability

To put this in the context of interoperability and what poor interoperability costs the economy and individual firms, in 2004 in a remarkable study the U.S. National Institute of Standards and Technology (NIST) attempted to identify and estimate the efficiency losses in the U.S. capital facilities industry resulting from inadequate interoperability. The NIST study focussed on interoperability problems attributed to the highly fragmented nature of the industry, the industry’s continued paperbased business practices, a lack of standardization, and inconsistent technology adoption among stakeholders. It concluded that inadequate interoperability cost the U.S. capital facilities industry $15.8 billion in annually in 2002, but qualified the conclusion by saying that this is likely a conservative figure because there were additional significant inefficiency and lost opportunity costs associated with interoperability problems that were beyond the scope of NIST analysis.
At GWF 2013 it was reported that Rijkswaterstaat, responsible for public works and water management as part of the Dutch Ministry of Infrastructure, has estimated that poor interoperability costs it € 800 million per year.

Barriers to integrating BIM and geospatial

Bram Mommers, who is with ARCADIS Netherlands, set the stage by looking at what the barriers are that are hindering the integration of geospatial into the constrcution process. (ARCADIS is a large international company that provides consultancy, design, engineering and management services in the fields of infrastructure, water, environment and buildings.)

Traditionally the challenge has been that civil engineering on one hand and geospatial on the other have been different cultures. The way Carl Steinitz put is that they work at different scales. Geospatial scientists deal with the universal, engineers with the very specific.

Bram gave some examples of these parallel worlds. Geospatial folks make maps, engineers and architects make drawings. Engineers and architects use CAD or BIM design tools. Geospatial folks use GIS. The geospatial standard for buildings and infrastructure is CityGML. The AEC standard for BIM models is Industry Foundation Classes (IFC).

ARCADIS has been involved in projects that integrated geospatial into the desing process. On the HOV Nijmegen project it was found that integrating geospatial and engineering design in a single database resulted in a single copy of each data element and multiple use. It simplified communication and increased the quality of the final design. It also enabled automated analysis of the consequences of design choices with the result that the planning cycle was shorter. Bram mentioned several other projects that benefitted from the integration of geospatial with the construction process.

Based on their experience with these projects, Bram and his colleagues concluded that there are three main barriers to the integration of civll engineering and geospatial.
- Semantics - for example, different terms used for the me things by geospatial analysts and civil engineers and designers
- Different topology - examples, (1) geospatial uses point, lines, and polygons; CAD/BIM uses splines, nurbs, and other parametric curves and treats polygons in a different way from geospatial topology; (2) features with location vs objects with location as an attribute
- Data formats - for example, geospatial data is stored in shape files, GML, and CityCML; CAD/BIM uses DWG, DGN, RVT files, and IFC
Mapping semantics

To address the first issue of semantics, a Dutch initiative called Concept Library (CB-NL) sponsored by the Dutch Council on Building Information (BIR), a joint government and industry initiative, has been created with the objective of developed an open, on-line system to map between the terminologies used in different domains. The goal is a single integrated model for construction (buildings and infrastructure) that would allow design, construction, maintenance and operations to share the same data. The concept library would be extended to include geospatial. The overall goal as Bram stated it is
- Ontology for the build environment - multiple sets of domain terminologies mapped on to it
- One language
- Combines geospatial and construction
The impacts of this appproach that Bram sees are
- Store once, use multiple times - avoid redundant data
- Integrated information management - based on data custodians
- Geolocation as a property of an object - in additon to features
Bram listed a number of organizations in the private construction sector that are supporting this initiative.

EPA Region 7′s GIS VIPBig Blue Thread
sur Planet Geospatial - http://planetgs.com

By Shawn Henderson

After several attempts at college, including the part-time approach, I decided in the mid 2000’s to start taking full-time classes and finish up my degree. I knew that I wanted computers to be my major, because I love technology, but I also had a strong affinity for geo-sciences. Not knowing much about geographic information systems (GIS) at the time, it seemed to be the perfect mix of geography, geology, and computers and therefore tailored specifically to my interests. I thought GIS was just going to be about map making, but I had a lot to learn. I was in the first pure GIS class that my alma mater, Park University offered. At the time there was no dedicated computer lab, and the text book was less than helpful, but it was interesting. I remember that in the computer lab on the main floor of the science building there were only five computers with ArcGIS licenses; we had to fight other students who were working on reports in MS Word to get access to the software we needed. Park’s Professor David Fox did the best with what resources were at his disposal, and he made the class really interesting and enjoyable. I developed a good relationship with Dave. One afternoon I was frustrated and fed up with the turn-over of professors in the Computer Science program back then, so I asked him if he would be my unofficial advisor. He agreed. From then on, we were good.

One afternoon I had enough of my computer programming class and decided to go for a stroll to clear my mind. I had been working on a user interface class but, the buttons and layout were not lining up. I wanted to throw the computer across the room. I walked over by the library and found an advertisement for an EPA summer intern program. At this point I had applied for a dozen internships and I chuckled to myself that I had absolutely no chance, but I also figured that I had nothing to lose. It just so happened that I had a certification in MS Access, and a group at EPA was looking for an intern to develop a tracking database in Access. I applied, the stars aligned, and I was accepted for the internship.

I quickly finished the tracking database, and I was able to detail into the Region’s GIS group and onto our Aqua Team with fellow colleagues like Roberta Vogel-Leutung and Laura Webb. I transitioned into the Student Career Employment Program and was offered a full time position with the Agency after I graduated. Sometime after that, my supervisor and I were brainstorming about GIS and we wondered if we could leverage my knowledge of Park’s program (which requires an internship) to offer their students a more robust GIS experience at EPA. I approached Dave Fox with the idea, and he thought it was a fantastic approach. Thus was born our GIS VIP (VOLUNTARY INTERNSHIP with PARK). From there our program has blossomed with more than 15 students working on EPA GIS projects.

Map completed by Park Intern

The experience of working with these students has been amazing! There has been a variety of unique personalities come through the door. I have had students that were worried and timid at the beginning, but by the end they were confidant and ready to save the world with GIS. I’ve also had students come through to find out how much database/computer work is involved and realize that the real world experience of GIS isn’t something they want to head towards as a career goal. In the end, not all the projects end up like we planned, but the experience the students and EPA staff get from these projects is invaluable. Students have had the opportunity to work with EPA staff which provides them with professional experience and contacts. In return the Agency gets a fresh look on things with young enthusiastic students and volunteer assistance on projects of substance.

Besides our work with Park, the Agency has several other voluntary opportunities. Currently EPA Region 7’s Office of Public Affairs, is seeking a volunteer intern to work on social media coordination who is motivated, hard-working, and interested in helping the EPA protect human health and the environment. You can find out all the details here. Additionally our Superfund program is seeking two volunteer interns to work on separate projects found here and here. These are great opportunities to build skills and your resume. Heck my old boss Jeffery Robichaud, also a fellow blogger, did his own volunteer internship with EPA in Philadelphia 20 years ago.

Shawn Henderson is an Environmental Protection Specialist with the Environmental Assessment and Monitoring Branch of the Environmental Services Division. He is a part of the Aqua Team, and conducts water quality sampling around the Region’s four states. He has a Computer Science degree from Park University and helped to develop the Region’s KCWaterBug app and kcwaters.org.

Simone Giannecchini: Fun with MapStore: Italian UNESCO Sites as OpenData
sur Planet OSGeo

Dear All,
there days the Italian UNESCO Sites of interests have been released as OpenData via this portal (NOTICE; we were not involved :)).

The data can be downloaded, there are WMS and WFS end endpoints available (using GeoServer), and there is a small webgis based on OpenLayers (which could actually be improved a litlle bit ;) ).
Well, OpenData + Open Services, this is really nice so I thought I could share a map I created with the cloud version of MapStore the same data with proper querying capabilities and so on.

So there you go, here below you can find a pretty simple map that just shows our UNESCO items, you can embed it in your site with the following HTML code:

<iframe height="400" src="http://mapstore.geo-solutions.it/mapcomposer/viewer?locale=en&bbox=-1851508.8592676,4102979.8193213,4351508.8592676,7429519.2898291&mapId=356" style="border: none;" width="500"></iframe>

Next steps would be customizing the info boxes and probaly adding more markers (get some info here) but I guess for the moment this is enough from us :). Ah yeah, I would probably also make good use of the buffer WMS parameter of configuration to make sure symbologies don't get cut in tiled development, here is some additional infomation.

Visit our online demo or download the MapStore binary, read the Quick Start guide and start to create and share your own maps. If you need more info, please check to the complete documentation wiki.

[Le blog SIG & URBA] Changement de forme des prescriptions nationales
sur GeoRezo.net - Géoblogs

Le cnig a adopté le 15 Avril dernier une nouvelle version des prescriptions nationales de numérisation des documents d'urbanisme.Du point de vue technique cette version n'est pas très différente de le mise à jour de l'année dernière que nous avons déjà expliquée sur ce blog.

Par contre cette version est très différente dans sa présentation. Exit le "cahier des charges" et voilà un document de synthèse des différents éléments contenus dans les prescriptions nationales.

Explications
Jusque là les prescriptions se présentaient sous forme d'un cahier des charges ou "CCTP" qui permettait avec quelques adaptations locales de lancer une consultation d'entreprise. Il était accompagné de documents techniques annexes décrivant plus précisément les données à produire; ainsi qu'un document d'introduction permettant d'expliciter la démarche et le contenu des prescriptions.

Au fil du temps cet emboitement de documents devenait effectivement compliqué à utiliser. Notamment quand on réalise une numérisation en interne et que l'on souhaite plus facilement accéder aux descriptions techniques hors règles de passation des marchés.

Le nouveau document
Le nouveau document se présente comme un seul document par document d'urbanisme : PLU et POS, et cartes communales. Les annexes sont de ce fait moins nombreuses puisqu'intégrées dans le document explicatif.

Cette nouvelle présentation coïncide avec la volonté gouvernementale de construire un géoportail de l'urbanisme avec l'objectif affiché de 80 % des documents d’urbanisme numérisés accessibles à l’horizon 2017. Il s'agit là de la deuxième mesure affichée dans le plan d'investissement pour le logement annoncé par le Président le 21 Mars.

Ces mesures contribueraient à une indéniable relance et à une probable accélération du mouvement actuel de numérisation et de mise en ligne des documents d'urbanisme.

When faced with incidents of that size, a utility is forced to look at all of its resources in preparation, including those it doesn’t typically utilize under normal conditions. Danny Petrecca, director of Product Management Enterprise GIS at Schneider Electric, explains how a typical implementation for an enterprise-wide GIS system can be used to better prepare utilities for disasters.

gvSIG Team: gvSIG 2.0: Biblioteca de símbolos “Forestry”
sur Planet OSGeo

Uno de los ámbitos habituales de uso de los SIG es el forestal. Orientada a esos casos de uso hemos realizado una nueva biblioteca de símbolos. Y como es habitual disponible desde el “Administrador d e complementos”.

Veamos como hemos realizado esta biblioteca, de modo que sirva como un nuevo ejemplo a los usuarios para crearse las suyas propias.

Para los símbolos puntuales (marcadores) hemos partido de dos fuentes distintas:

- Por un lado la colección de símbolos utilizada por el NPS (U.S. National Park Service). Una excelente colección de símbolos de dominio público.

- Por otro lado hemos utilizado la fuente Trees & Shrubs realizada por Jim Mossman, también de dominio público.

Para añadir los símbolos de NPS, hemos seguido lo indicado en este post. Para facilitar la identificación de símbolos, hemos utilizado una herramienta de renombrado masivo de archivos, ya que el nombre que gvSIG da a cada símbolo es el nombre del fichero; en nuestro caso hemos utilizado pyRenamer. Mediante Inkscape hemos generado los distintos símbolos de selección (coloreando de amarillo cada símbolo y añadiendo la terminación “_sel” al nombre del fichero).

Todo preparado para utilizar el importador de símbolos de gvSIG. Importamos los símbolos a “Forestry/NPS”. De forma automática se crea la nueva biblioteca con el conjunto de símbolos puntuales importados.

A partir de lo indicado en este otro post generamos los distintos ficheros SVG que representan un conjunto de árboles y arbustos. Utilizamos el importador de símbolos, almacenándolos en Forestry/Trees & Shrubs.

Además de símbolos puntuales, queríamos que esta biblioteca contuviera un conjunto de símbolos de líneas y de relleno habituales en los mapas forestales.

Hemos generado tanto símbolos lineales:Como símbolos de relleno:

Ya sólo nos queda crear el paquete tal y como explicamos en este p ost.

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

Taking Tilemill 2 for a SpinGeoSprocket Community Jive
sur Planet Geospatial - http://planetgs.com

When I took my first GIS class, I was told that 5% of my time would be spent making maps, while 90% of it would be spent corralling data into usable format and 5% would be spent beating an unresponsive plotter with a cardboard tube. This balance has definitely changed as interoperability has gone from prayer to practice, but I've continued to be frustrated by the time I feel gets lost to a missing shapefile extension or a falsely-defined projection.

For all the fun afforded us by Mapbox's original Tilemill map design platform, it's always been sort of a GIS-y hassle to wrangle data into it. Mind you this is slight, glancing criticism - it's NOTHING compared to getting your geodata to work in Illustrator or any actual GIS platform. But I always found myself wishing I could spend less time racking my brain for where I put that awesome building footprint layer, or trying in vain to find the right ORDER BY syntax for a PostGIS datasource.

Perhaps you've heard, but Mapbox sort of solved my whiny problems. Tilemill 2 is in unsupported alpha, but it's already fulfilling my dream of data-agnostic cartography. The basic idea is that the world - as derived from OpenStreetmap - is some pretty centralizable basedata, so why not just tap the source and style it however you like? Instead of pulling extracts or copies or subsets, Tilemill 2 just gives you the whole damn world, all 330GB-and-counting of it, via super-fast vector tiles (great explanation here). You get to style those tiles with the CartoCSS language, and at that point they're ready for your audience.

It is A LOT of fun to have the world at your fingertips:

For the moment there's no export or serving option, and it'll be interesting to see what Mapbox does with this tool in its already-robust custom mapping lineup. It's also worth noting that planet.osm is not ALL TEH DATAZ - we'll always need a way to use local or personal geodata. But this is a great leap for an already-impressive platform.

It's liberating to be able to focus on cartography with the building blocks already in place.

Props to Gretchen Peterson for some great color ideas as I fiddle with this.

Not the New Google Maps
sur Google Maps Mania
Because of the design changes in the new Google Maps, v4 of the Maps API must be in the pipeline. I expect however that the release is some way off.

Inspired by the new index card effect in Google Maps I decided to have a little Sunday hack to see if I could create something similar. Here's the result, Not the New Google Maps.

First off to add the new look map base layer it is a simple process to add
```
google.maps.visualRefresh
```
to the javascript for the map.

Initially I decided to replace information windows with a slide-down index card. It was simple enough to create a div element for the index card and use jQuery to create a slide-down and slide-up effect for the card. Then it was just a matter of using
```
document.getElementById('divName').innerHTML
```
and a call to open the card index, inside the marker's event listener.

After achieving that however I decided to remove the example marker from the finished map.

One of the really impressive new features in the new Google Maps is the reverse geo-coding that happens when you click on the map. When the user clicks on a location on the map a card opens showing the location's address and a small thumbnail of the Street View available.

So I decided to use my index card design to achieve something similar. When you click on the map I geo-code the location and add a little static Street View to the slide-down index card. If I get the time it should be a simple enough process to add a function so that when the user clicks on the static Street View the map is replaced with the full interactive Street View.

A tale of two citiesANDREW ZOLNAI BLOG
sur Planet Geospatial - http://planetgs.com
Last I posted on vector online GIS, and that appears to be gaining traction. Mapbox offers through TileMill and OpenStreetMaps editing. These are new an emerging technologies that are exciting, and it contrasts with Esri who offers a slew of tools on the desktop and in arcgis.com. WMS is for example still immature on giscloud.com (though it is OGC compliant now), as are the symbology and labels. They do not offer model builder like Esri or Qgis (thru Sextante). But they do offer a service to process GIS functions online and allow to load data direct from web source, avoiding costly down- & up-loads. Here I compare how I used a 180K vector dataset from NOAA NGDC described previously.

This is very much a work in progress, stay tuned for Arcgis Online for example. Also Google Fusion Tables I used elsewhere are not appropriate in this context. And of course there are many many more platforms bird-dogged for example by the blog roll below to the right. Here is, however, what GSHHG maps looks like in giscloud.com and ArcGIS for Home Use that offer modest barriers to entry:
1. giscloud.com online

Nathan Woodrow: On being an open source contributor
sur Planet OSGeo

Joining an open source project has been one of the best things I did for my career. To better myself in the process of improving QGIS. To grow as a GIS professional. To learn to be part of team and respect each others ideas even if don't agree. To be open to ideas that others have spent a lot of time on. To not just be single tool pusher and learn a wider range of toolkits. To work with people who you have never seen in person, or even talked to.

How did it feel to join an open source project? Scary but awesome I would say. Scary in that that everyone would read my code - my very amateur code. Scary in that I had never really joined an open source project before and wasn't sure what everyone would think of my work, or my ideas.
Scary because there are so many people better at this than me and they might think I'm crap.

However all of this fear is outweighed by the awesome feeling of knowing that people benefit from the work you, and the rest of the team, put in. Sometimes even the small things can make a huge difference to what people can do with your software - and yes I did use "your software" on purpose. Contributing to open source means you, personally, are part of the software. Being a contributor, for me at least, gives you a deeper relationship with the project. The kind of relationship that sees you staying up at night when the rest of the family is in bed trying out a new idea, fixing some annoying bug, or writing a blog post about being an open source contributor. All for free! - well mostly. Some call it obsession I prefer passion.

It's not pretty roses all the time. Passion can lead to burnout. Trying to be involved in most of the major parts of the project can result in stretching yourself thin. A project that never sleeps makes this even harder. The wave of ideas can sometimes be a distraction from just getting stuff done. Rejection of your work can be hard to handle the first time, you just have to remember it's never personal. Most of these are just personal demons that need to be managed but they do sneak up if you enjoy what you do. Having a family - and an xbox - helps to ground you and make sure you don't spend all your free time on the computer hacking away.

Like I said, and despite personal demons, joining an open source project has been one of the best things I did. There is an emotional kick working on something and seeing it used by other people. I didn't expect my expression based labeling addition would get such good remarks but it did and that helped push me further into becoming a QGIS contributor.

The Google Maps of the Week
sur Google Maps Mania

What with Google I/O and the launch of the new look Google Maps, it has been a reasonably quiet week for reviews of new Google Maps apps. At Google Maps Mania our attention has been drawn away by the live streams from I/O and playing with the new look Google Maps.

However, some great maps did get featured this week.

One map that grabbed my attention this week was from Rough Guide. One feature of the Rough Guide site that I really like is how you can drill down from general reviews of countries, to reviews of individual towns and cities and then search for great individual locations to visit within those towns and cities.

As you navigate the Rough Guide website look out for the 'view map' option that allows you to view Rough Guide recommended locations on a map. The drop-down menu above the map allows you to select individual countries and cities.

If you select a country or city from the menu then a general introduction to your chosen destination is given beneath the map and all the Rough Guide recommended places to visit are displayed on the map.

Another interesting map that came to our attention this week was España en llamas (Spain in Flames), a Google Map displaying ten years of data about the location of forest fires in Spain. The map includes data on 1,508 fires, 699,560 hectares burned, 24 deaths and 191 injuries.

If you click on the 'Explora los incendios' link above the map you can filter the data displayed on the map. The filter controls allow the user to filter the results displayed on the map by cause of fire, fires that caused deaths, by location and by the size of the fire.

A time-line tool beneath the map also allows the user to explore each of the filtered results by year. One neat feature of this map is the use of relatively sized map markers to show the size of each individual fire.

The Hand Drawn Maps of the Week
sur Google Maps Mania

This week saw the 70th anniversary of the World War II Dambuster raids. On 16–17 May 1943 an attack on German dams, carried out by Royal Air Force No. 617 Squadron, subsequently known as the "Dambusters", used a specially developed "bouncing bomb" invented and developed by Barnes Wallis.

The BBC has put together an interactive map that retraces the mission. The interactive uses a hand-drawn map from the official June 1943 British Air Ministry report on the Dambusters raid. The map shows the routes taken by the planes, the location of the planes that crashed and the location of the German dams.

The MapBox Blog has this week been showing off the power of their MapBox Streets with vector tiles.

Using vector tiles ensures the speed and scalability of MapBox maps. It also allows for some amazing styling of the map tiles. Using MapBox anyone can make "a totally custom branded map, of the entire globe, that is lighting fast on every device."

The blog post includes a number of beautiful examples of styled maps. I think my favourite is the hand-drawn map style (shown in the screenshot above).

En bref cette semaine...

sur Geo By The Cloud

Comme chaque semaine, vous trouverez ci-dessous une liste évidement subjective et incomplète des news du monde de la cartographie et du geospatial:

		J'annonçais la semaine dernière l'arrivée d'une nouvelle version majeur de l'application Google Maps. De manière synchronisée, Google a annoncé cette semaine la disponibilité de ces évolutions (en mode expérimental aujourd'hui, sortie en final prévue pour aout prochain) dans l'API Google Maps V3. Avec une simple ligne de code, vous pouvez bénéficier dès maintenant de ces évolutions (Basemap, look-and-feel des controles, nouveaux markers par défaut ....pour l'essentiel). Plus d'infos dans le Geo Developers Blog de Google.
		A l'occasion de la conférence mondiale Google I/O, différentes annonces ont été faites autour d'Android avec notamment, en terme de géolocalisation, l'arrivée de 3 nouvelles APIs: Fused Location Provider. Il s'agit d'un nouveau mode de localisation censé être plus précis, et tirant parti du réseau cellulaire, du WiFi et du GPS. La principale annonce, très applaudie dans la salle, concerne la consommation électrique, puisque Google affirme que cette API permet une géolocalisation tirant moins de 1% de la batterie par heure. Geofencing. Cette API va permettre aux développeurs de mettre sur pied jusqu'à 100 points sur une carte, qui permettront, lors d'événements, d'activer des fonctionnalités ou d'aider à la localisation rapidement lorsque l'appareil et son utilisateur entrent dans un rayon proche de ces points. Activity Recognition. Il s'agit cette fois d'une API de reconnaissance du mode de déplacement utilisé en temps réel par l'utilisateur. Qu'il soit à vélo, à pied ou en voiture, le téléphone pourra le savoir, et les développeurs pourront programmer des fonctionnalités se basant sur ce renseignement. Plus d'infos dans cet article.
		Esri annonce deux nouvelles versions de produit cette semaine: une version 3.5 de l'API ArcGIS for JavaScript proposant peu d'évolutions fonctionnelles mais des évolutions syntaxiques avec l'implémentation du class.on() pour gérer les événement associées aux principales classe de l'API Web. une mise à jour d'ArcGIS for Windows Phone améliorant l'expérience utilisateur en particulier sur les appareils
		Les produits AutoCAD Map 3D 2014, AutoCAD Civil 3D 2014, Autodesk InfraWorks 2014 et Autodesk Infrastructure Map Server 2014 sont maintenant disponibles en français. Plus d'infos sur le blog de Gwenael.
		Le site de diffusion sur le Web de vidéos YouTube vient d'annoncer la disponibilité d'une nouvelle fonctionnalité YouTube Trends Maps. Celle-ci permet de visualiser les vidéos les plus populaire selon différents critères: sexe, age et zone géographique. Cette présentation cartographique de la fréquentation du plus grand site de diffusion de vidéos en ligne aura sans nul doute du succès. Je parie que nous aurons rapidement des analyses "géo-socio-comportementales" émergées de ces nouveaux types de rapports. Regrettons tout de même que ceux-ci ne soient disponibles
		Mapbox détaille les caractéristiques de son infrastructure de Cloud et propose une cartographie de ces serveurs.
		Les spécification des annexes II et III de la Directive INSPIRE sont-elles officielles. Le point sur la question dans le blog de Marc Leobet.
		A noter cette semaines dans la presse en ligne deux articles illustrant les révolutions en cours dans le domaine du géospatial. Le premier dans le Monde.fr évoquant les nouveaux challenge en termes de constitution des bases de données par l'IGN et sur la cartographie collaborative avec l'exemple d'OSM. Le second article dans LesEchos.fr traitant des nouvelles applications cartographiques mettant en oeuvre des sources de données innovantes comme les réseaux soxiaux, la 3D ou encore les données de localisation des téléphones mobiles.
		Enfin, pour se détendre, GeoGuessr un jeu en ligne basé sur Google Street View qui consiste tout simplement à trouver la localisation géographique d'un lieu choisi n'importe où dans le monde. Plus vous serez près de la véritable localisation, plus votre score sera important. Bonne chance !

Et pour finir en sourire, comme chaque semaine, une scène insolide de la vie quotidienne capturée par Google Street View (en Estonie):

Jackie Ng: MapGuide tidibts: The resource dependency chain
sur Planet OSGeo

You probably know in MapGuide that there is a whole different bunch of type of resources available at your disposal, when authoring up your data, maps and applications.

You probably also know that if you move, rename or delete a resource you may be affecting and/or breaking other resources that depend on it.

How about the big picture? Well here's one I've prepared earlier.

As you can see, with the exception of the Load Procedure, Application Definition and Web Layout, every other resource type has a dependency on another resource type.

Consider what you may be potentially breaking when you move, rename or delete a given resource.
