Off the Map - Official Blog of FortiusOne: The 5th Day of Analytics – Buffer
sur Planet Geospatial - http://planetgs.com
Carrying on with The 12 Analytics of Christmas, let’s take a look at one of the simplest yet most powerful analytics feature – Buffer. In a nutshell, Buffer allows you to set a perimeter around your points, lines or polygons by a specified distance. So if you want to show a ‘noise’ perimeter around a road or display transit stops within 100 m. radius of your store, the buffer comes in handy.

To better illustrate the functionality, let’s create a simple analysis of all Washington DC metro stations with 500m buffer. Here is how it works.
1. Grab metro stations data set from Geocommons.
2. Click on Analyze Data and select Buffer option.
3. In the Buffer menu, specify the distance parameter and you are done!
Here is the beautiful resulting map.

One thing to keep in mind is that buffer areas look skewed because of the map projection – this is why in the example above the buffer areas are displayed as ellipsoids rather than circles.

The fist publicly available version of GeoShield, version 0.2.1, has been released.

What it is? "GeoShield is a project born to offer a centralized way to define security access-control to geo-services. It acts like a proxy, intercepting all the communications between clients and OGC compliant services (WMS, WFS, and in future WPS, SOS). GeoShield is able to manage users and groups, it handles authentication and privileges settings among groups and registered services. It is capable to analyse requests applying the filters set to the user and manipulating the response. It is a server side security software to secure OGC services."

We mentioned it previously in the FOSS4G summary, but it's really the first time people can actually access the code. Another similar open source tool is GeoPrisma.

Linfiniti Geo Blog: Vector rule editor and polygon line styles in QGIS
sur Planet Geospatial - http://planetgs.com

Note: This post discusses features in QGIS Trunk – they will make their way into the future QGIS 1.7.

One of the things I love about QGIS is how people arrive into the developer community and just start pitching in. Its the classic ‘scratch your own itch’ phenomenon at work and I never grow tired of watching it. This week, QGIS got a couple of interesting new features. The first is and implementation of a graphical rule builder for when you are using rule based vector symbology. Rule based symbologies allow you to create classes of features based on arbitrary rules, but up until now you had to write those rules manually. Nathan Woodrow’s recent page implements a query builder that lets you point and click your way to easy rule creation.

Rule editor for vector layers

Another nice new feature was committed by Martin Dobias this week. It allows you to treat the stroke / outline for polygons as a separate entity when rendering. So now you can render a polygon with one or more discrete line styles as seen in the image below. In addition you can render a marker in the polygon centroid. The cartography capabilities in QGIS are really looking good these days and I have seem some beautiful maps that folks have come up with using the new generation symbology.

In QGIS 2.0 we will drop the old symbology implementation – but I get the feeling most won’t miss it very much. The only time I ever use the old symbology implementation is when I am exporting projects to mapserver or mapnik.

got geoint?: Friday’s Food for Thought: The Truth is Stranger Than Fiction
sur Planet Geospatial - http://planetgs.com

Welcome to the critically acclaimed Friday’s Food for Thought post from got geoint? As we mentioned yesterday, the WikiLeaks saga is ripe for a Hollywood blockbuster (Matt Damon as Julian Asange?) and this whole thing makes us realize that the truth is often much stranger than fiction. So, what a perfect theme for today’s FFT post. But before, we dive into this topic, we wanted to let our faithful readers know that we have plenty of got geoint? stickers left over from GEOINT 2010. So, if you are interested in getting more stickers for your car (or perhaps use as stocking stuffers), feel free to email us at info@usgif.org. Happy Friday!

Counting the WikiLeaks Story Lines — Stranger than Fiction
With every new day the WikiLeaks saga seems to reveal another story line. As the expression goes, “you can’t make this stuff up.” In the process, it’s highlighting rapidly changing — and often unstable — elements in Internet-based communication. First let’s take the emerging model of cyber attacks. People no longer just get angry at home or in bars, they attack those they disagree with online. First supporters of WikiLeaks were subjected to Distributed Denial of Service (DDoS) attacks, then companies and organizations deemed against WikiLeaks were targeted. Read the full Work, Wine and Wheels blog post here.

Truth is Stranger Than Fiction – Where Did The Expression Come From?
It’s amazing how some expressions can just work their way into our collective vernacular. “Truth is Stranger Than Fiction” is certainly one of these expressions that has just stuck. Why? Well, because reality is often way more odd and interesting than anything that an artist, poet or writer could make up. Speaking of poet, Lord Byron came up with this saying in his 1823 poem called Don Juan. Perhaps the editorial team of got geoint? can come up with a GEOINT-related expression that will stand the test of time? Hmmm…I believe we have a New Year’s challenge to tackle!

Truth is Stranger than Fiction — Real Examples
A man hit by a car in New York in 1977 got up uninjured, but lay back down in front of the car when a bystander told him to pretend he was hurt so he could collect insurance money. The car rolled forward and crushed him to death. In 1983, a Mrs. Carson of Lake Kushaqua, N.Y., was laid out in her coffin, presumed dead of heart disease. As mourners watched, she suddenly sat up. Her daughter dropped dead of fright. A fierce gust of wind blew 45-year-old Vittorio Luise’s car into a river near Naples, Italy, in 1983. He managed to break a window, climb out and swim to shore — where a tree blew over and killed him. Mike Stewart, 31, of Dallas was filming a movie in 1983 on the dangers of low-level bridges when the truck he was standing on passed under a low-level bridge — killing him. Crazy huh? Check out more real-life examples of truth being much stranger than fiction here.

All I Got is a Red Guitar, Three Chords and The Truth – Bono
So, in coming up with a song that discusses the truth, the lyric “All I got is a red guitar, three chords and the truth” from U2′s version of All Along the Watch Tower came to mind. Well, because that pretty much sums up rock n’ roll, which is essentially about expressing the truth. So, with that, we hope you enjoy U2′s cover of this classic Bob Dylan song from Rattle and Hum.

This HTML5 video from Japanese band Soul River integrates with your Twitter and Facebook accounts and with your webcam to create a truly wild and amazing web musical video.

The video was obviously inspired by The Wilderness Downtown's experimental HTML5 video. Like the Wilderness Downtown video Soul River makes use of numerous browser windows and your geographical location.

Using your browser's geolocation detection capabilities the video displays a Google Map of your location. The Soul River singer is then shown walking across the map. There is a lot more amazing stuff in the full video but really you have to watch it yourself.

To watch the video you will need a browser that supports HTML5. Use Chrome if you have it.

British Road Casualties 2008 & 2009

Google Maps built with Fusion Tables can support huge amounts of data and can also now support spatial queries. This Google Map of British Road Casualties is an excellent example of a map using Fusion Tables to great effect.

The map shows the location of nearly 50,000 fatal and serious injuries on British roads for 2008 & 2009. The map also makes great use of queries. It will load the nearest 100 results for any searched location and the map also reloads the nearest markers on the fly as you pan the map around.

As well as these spatial queries it is possible to query the results shown by year of serious injury or fatality.

gvSIG Team: 6as Jornadas Internacionales de gvSIG
sur Planet OSGeo

Me animo a comenzar a contar mis impresiones sobre el evento gvSIG con más solera, complementando a los post de otros compañeros.

Durante los días 1, 2 y 3 de diciembre tuvieron lugar las 6as Jornadas Internacionales de gvSIG. Jornadas que se vieron acompañadas los días previos por una serie de eventos paralelos. Estas jornadas, bajo el lema “Conocer para Transformar”, han tenido un alto contenido técnico -en forma de talleres- y se han organizado con el objetivo principal de seguir creando comunidad. Como comentábamos en la apertura del evento, si queremos cambiar el modelo actual imperante, nuestra principal arma es la organización. Debemos estar organizados a todos los niveles para aprovechar las oportunidades que presenta el software libre, para tener capacidad real de transformación. Frente a la desigual competencia que promueve el software privativo, colaboración y organización.

Entre los eventos paralelos, el día 29 de noviembre pudimos asistir al primer BugSprint, durante el cual se realizó una introducción a las formas de testeo del proyecto gvSIG y se puso en marcha un maratón de caza de errores de la última versión publicada de gvSIG Desktop.

Parte del conjunto de errores detectado fue corregido en el CodeSprint del día siguiente, que juntó durante un día a cerca de una treintena de desarrolladores del proyecto, de 18 organizaciones distintas. Los participantes y resultados del mismo los podéis consultar en la web que se creo para organizar dicha actividad. Parte del trabajo realizado durante el CodeSprint lo veremos reflejado en gvSIG Desktop v.1.11

En esta sexta edición hemos contado con la participación de más de medio millar de asistentes, de un total de 18 países.

A través de media docena de talleres aprendimos más sobre Sextante, gvSIG 3D, gvSIG Mobile, a desarrollar sobre gvSIG 2.0, a diseñar formularios para Navtable y a publicar información siguiendo los estándares OGC.

Cerca de 40 ponencias nos han mostrado la expansión y diversidad de usos de la tecnología gvSIG: gestión forestal, saneamiento, gestión municipal, transporte, emergencias, pesca, arqueología, educación… Hemos presencia ponencias de proyectos en Alemania, Argentina, Brasil, Bolivia, España, Francia, Honduras, Italia y Venezuela.

Más allá de las ponencias técnicas, fue muy interesante la participación de Antonio Rodríguez de IGN y Martín García de la CIT, donde se hizo un repaso a la legislación española y como esta apuesta claramente por la utilización de software libre (sobre esto deberíamos escribir un post un día de estos).

En definitiva, y como comentó más de un asistente, unas jornadas hechas por y para la Comunidad. Una jornadas que demuestran nuevamente que hemos llegado a un punto en que gvSIG es un proyecto sólido, extendido por todo el planeta y que, como desde un principio, sigue fiel a los valores que le han hecho llegar aquí: colaboración, trabajo y humildad. Un proyecto que trabaja bajo la premisa de compartir el conocimiento. Conocimiento que sirva para transformar.

Jackie Ng: My MapGuide Wishlist
sur Planet OSGeo
I made one for FDO, so here's one for MapGuide...
1. A desktop-based variant of the Geospatial Platform API
Despite web applications being touted as the best thing since sliced bread. I believe there is still a sizable market and demand for a Desktop-based MapGuide product without the full-blown feature set of AutoCAD Map3D.
Autodesk used to have a product like this. It was called Envision (before that, it was called OnSite Desktop) and it worked with MapGuide 6.x (or possibly older) SDF files. There hasn't been anything similar from Autodesk since.
That's not to say we can't do it ourselves. It is conceptually possible to take MapGuide in directions that do not involve the Server and Web Tier, but the amount of implementation (or re-implementation) work required is just too much. There are huge swaths of useful utility code that is currently stuck in the Server and WebTier code-bases that should really be inside some sort of reusable utility library.
Not to mention that there are several Server-only modules that have no real server dependencies. There is utility outside of a MapGuide Server / Web Tier in having standalone MgDrawingService, MgRenderingService, MgKmlService and GwsQueryEngine modules. For most convenience, it would be nice to have them merged into the base platform libraries (MgPlatformBase.dll).
Such a current development requires working with the full MapGuide source tree, not exactly the smallest thing out there to have to download/checkout.
That way, the only real implementation effort would be:
- MgFeatureService (can simply be a straight wrapper around FDO).
- MgResourceService (can simply be a pre-defined directory with a SQLite-backed database to store metadata and resource dependencies).
- MgMapBase (can simply reuse MapGuide implementation)
- MgLayerBase (can simply reuse MapGuide implementation)
- MgSelectionBase (can simply reuse MapGuide implementation)
2. A HTML5/Flash/Silverlight vector viewer with offline support
A rich HTML5/Flash/Silverlight viewer has the primary benefits.
- Reduced server load and better performance. The viewer would only need to perform queries for features. Everything else is done client-side.
- Richer user experience due to everything being done client-side
- Client side features are actual geometries, as we a not requesting a rendered image everytime we pan/zoom/refresh/etc. So we can do things like client-side selection, object snapping, etc.
I emphasize offline support (which HTML5 and Silverlight can do, not sure about Flash) because if the previous item is too much effort, an offline-capable web map viewer is the next best thing.
The old MapGuide 6.5 ActiveX viewer could do this through "fat" MWF files (filled with static layers). I just wish there was something similar with current MapGuide technology.
3. A scalable Fusion Legend widget
Fusion has had many teething problems since its introduction several releases ago, but nowadays it is mostly functional and usable, except for the Legend widget. Given a moderately large map, the legend widget just breaks down.
It also doesn't help that fusion is the default previewing mechanism in MapGuide Studio so you can expect previews on large themes to timeout consistently (that's what you get for embedding Internet Explorer!). I've had to advise clients from using Fusion simply because I knew it couldn't handle the large maps that they have, which is a shame because it perfectly satisfied all their other requirements!
4. A way to preserve tile sets.
Ever change something innocuous like the title of your Map Definition and MapGuide suddenly takes off and nukes your tile set from orbit? Yes, it's very annoying because it isn't exactly fast to produce these tile sets!
I think the best solution is to have a tile set defined as a separate resource, any Layer Definitions (and by extension, Feature Sources) that are used as part of this tile set resource are locked from editing. My current thinking is that a tile set definition (if you will) would have the following information:
- Path to where the generated tiles will be stored. Can be %MG_DATA_FILE_PATH% for managed, or an external path or alias. Come to think of it, %MG_DATA_FILE_PATH% is probably a bad idea as packaging will take an eternity.
- The Layer Definitions participating in this tile set.
- The Coordinate System (to re-project any non-matching layers)
- The scales applicable for this tile set.
MapGuide already knows the dependency chain of any resource, so it can stop any edits made to dependent layers and feature sources of a given tile set. The tiled layer component of the Map Definition would be deprecated in favour of references to tile sets (or probably be a new resource type so as not to break the additive qualities of previous schema revisions)
This way once a tile set is defined, it is not possible to trash the generated tiles unless you say so as layer and feature source changes/updates/deletions will be denied by MapGuide due to its knowledge of dependent resources.
5. Feature Write capabilities for the mapagent
Failing that, merge GeoREST into MapGuide, you'll get pretty much the same result.
6. A DWG FDO provider
I understood in the past why it was not possible. But the release of AutoCAD for Mac has proven that Autodesk finally have multi-platform DWG access technology. So get to it! It will definitely add extra value to a licence of MapGuide Enterprise

The Map Guy(de): My MapGuide Wishlist
sur Planet Geospatial - http://planetgs.com
I made one for FDO, so here's one for MapGuide...
1. A desktop-based variant of the Geospatial Platform API
Despite web applications being touted as the best thing since sliced bread. I believe there is still a sizable market and demand for a Desktop-based MapGuide product without the full-blown feature set of AutoCAD Map3D.
Autodesk used to have a product like this. It was called Envision (before that, it was called OnSite Desktop) and it worked with MapGuide 6.x (or possibly older) SDF files. There hasn't been anything similar from Autodesk since.
That's not to say we can't do it ourselves. It is conceptually possible to take MapGuide in directions that do not involve the Server and Web Tier, but the amount of implementation (or re-implementation) work required is just too much. There are huge swaths of useful utility code that is currently stuck in the Server and WebTier code-bases that should really be inside some sort of reusable utility library.
Not to mention that there are several Server-only modules that have no real server dependencies. There is utility outside of a MapGuide Server / Web Tier in having standalone MgDrawingService, MgRenderingService, MgKmlService and GwsQueryEngine modules. For most convenience, it would be nice to have them merged into the base platform libraries (MgPlatformBase.dll).
Such a current development requires working with the full MapGuide source tree, not exactly the smallest thing out there to have to download/checkout.
That way, the only real implementation effort would be:
- MgFeatureService (can simply be a straight wrapper around FDO).
- MgResourceService (can simply be a pre-defined directory with a SQLite-backed database to store metadata and resource dependencies).
- MgMapBase (can simply reuse MapGuide implementation)
- MgLayerBase (can simply reuse MapGuide implementation)
- MgSelectionBase (can simply reuse MapGuide implementation)

Jackie Ng: My FDO wishlist
sur Planet OSGeo
Since it's that time of the year, and Autodesk loves them customer surveys and wishlists...
1. A way to use the FDO API in languages other than C++/.net in a multi-platform manner
FDO is a multi-platform API. I like .net, it is portable too assuming you target a safe and mature subset of the .net framework libraries (which I already do).
Unfortunately, the .net wrapper for FDO is not multi-platform and if you're not careful the .net Garbage Collector who is normally your friend, becomes your worst enemy as it prematurely cleans up your wrapped FDO objects from under your feet and you're greeted with the all-too-common AccessViolationException being thrown at you.
SWIG can wrap C++ code in a multi-platform manner. GDAL does this. MapGuide already does this, why not FDO as well? There's already a Python wrapper generated by SWIG (albeit Windows-only last I checked), so it's not exactly impossible!
I don't mind having to use C++ if I have no other choice. But higher level languages does yield greater productivity. It's how I got FDO Toolbox to become so feature-packed in such a short period of time. The fact our Linux users cannot use FDO Toolbox because of lack of flexible development options (that is not C++) is disappointing.
2. Champion SQLite as the goto flat-file format for FDO
Now I don't mean product support. Because it's already getting love from the latest releases of AutoCAD Map3D and MapGuide Studio. I mean having SQLite become the de-facto flat file format that showcases all of the features supported by FDO.
What do I mean exactly? I mean features you normally find in a RDBMS provider like:
- Association Properties
- Object Properties
- Schema Element Attributes
- etc
3. A FDO provider for MapGuide
Sure, there's no write capability built into the mapagent, but having a read-only FDO provider for MapGuide would greatly improve interoperability between FDO client applications and MapGuide. It would basically be like WFS, but without the impedance mismatch and loss of metadata. As MapGuide is built on FDO, it knows everything about FDO and the capabilities can be parameteric with respect to the underlying Feature Source.
You could possibly even have raster support by just extending existing Rendering Service APIs with required raster functionality (querying, sub-sampling, etc) and exposing this through the mapagent.
4. Consistent Schema Naming Conventions
This is already a well-documented problem, but I'll extend it with a possible solution.
For those providers that hard-code a schema name (because they don't support the concept of a logical schema and just need a name), how about instead we define the default schema name in an external configuration file and these providers can read off of this file instead? This way, not only is it unified, but unified to your preferences.
Having to write implementation-specific code in an abstraction layer like FDO defeats the whole concept!
5. Parametric Capabilities
Capability APIs break down on providers like ODBC and OGR due to their "one size fits all" nature of these providers. It would be nice if ODBC and OGR actually have capability discovery, for these capabilities to be translated to corresponding FDO capabilities, so we don't get a whole bunch of -1 values for FDO capabilities like maximum length of a property.
6. Android/iPhone support
Hey this is a wishlist after all! Smartphones are all the rage these days. No need to port everything. Just the base SDF/SHP/SQLite providers would suffice.

Letters from the SAL: Webinar: Raster Processing in ArcGIS with Map Algebra and the Raster Calculator
sur Planet Geospatial - http://planetgs.com

I will be presenting a webinar on Raster Processing in ArcGIS with Map Algebra and the Raster Calculator December 20th from 2:30PM - 3:30PM EST. The webinar is hosted by the Vermont Center for Geographic Information (VCGI). To register click here. Below is a brief description of the workshop. Hope to see you there.
Map Algebra is the underlying language for Spatial Analyst tools and operators. This workshop will demonstrate simple and effective techniques for processing raster datasets in ArcGIS within the Raster Calculator using Map Algebra expressions. This workshop is designed for ArcGIS users who are familiar with raster data, but don’t have much experience with either Map Algebra or the Raster Calculator. Demonstrations will be done using both ArcGIS 9.3 and ArcGIS 10, and key changes to Map Algebra and the Raster Calculator at version 10 will be covered.

Edmar Moretti: Uso da API do Twitter no i3Geo:clique no mapa e veja os posts
sur Planet OSGeo

A localização espacial de posts do Twitter ainda é pouco explorada, mas aos poucos a API de acesso aos dados vai melhorando e já permite algumas implementações práticas.

No i3Geo, implementei a pesquisa de posts por meio de um clique no mapa. As opções ficam na ferramenta de identificação, ou seja, o usuário clica no mapa e, além das opções de informações sobre as camadas do mapa, pode-se pesquisar o mesmo ponto no Twitter. Utilizei duas funcionalidades da API do Twitter, a primeira busca os posts mais recentes dentro de um raio cujo centro é o ponto clicado. a segunda opção, busca o registro de lugares naquele ponto para que o usuário escolha um, aí então, são mostrados os posts originados nesse lugar.

Essa segunda opção é nova no Twitter, sendo que fiquei sabendo dela apenas hoje.
