GeoTools 10.0 Released

Another software that was released at FOSS4G 2013 a week ago was the open source Java library GeoTools 10.0.

From the announcement: "Summary of the new features for the GeoTools 10.x series:

  • Structured grid coverage readers allow raster data sources that publish composite data products to expose individual rasters (ie granules) for processing, while still providing a seamless experience for rendering. The mosaic and NetCDF modules are the first ones to implement these new interfaces.
  • Efficient support for multiple coverages in GridCoverageReader provides ad-hoc access to raster formats that publish more that one data product. A image mosaic made of NetCDF granules and single file NetCDF sources are the first implementors of these new capabilities
  • new implementation of Shapefile DataStore (based on ContentDataStore superclass). This upgrade should be seamless for all users using DataStoreFactoryFinder. If you explicitly made use of the ShapefileDataStore or IndexedShapefileDataStore class please check the upgrade instructions.
  • The transform module graduated to supported status, providing a seamless way to rename, retype and hide SimpleFeatureSource attributes, as well as creating new ones based on OGC Expression
  • Additional OGC modules for the WCS 2.0 and WCS 2.0 EO models as well as adding XML parsers and encoders

The 10.x series has a number of research and development activities that may be of interest:

  • NetCDF has been updated to take advantage of the new coverage API introduced above
  • GeoPackage: a sample implementation of the geopackage spec that is currently being developed by the OGC"

pgRouting 2.0 Released

It's been a crazy week for me and I essentially failed to aggregate geonews - expect me to catch up in the coming days.

The open source routing engine pgRouting version 2.0 has been released, and this a major new release. We mentioned it a few times since 2010.

A reminder of what pgRouting is, from the official website:

pgRouting extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality.

Advantages of the database routing approach are:

  • Data and attributes can be modified by many clients, like Quantum GIS and uDig through JDBC, ODBC, or directly using Pl/pgSQL. The clients can either be PCs or mobile devices.
  • Data changes can be reflected instantaneously through the routing engine. There is no need for precalculation.
  • The “cost” parameter can be dynamically calculated through SQL and its value can come from multiple fields or tables.

And here's a list of features including what's new for version 2.0:

  • All Pairs Shortest Path, Johnson’s Algorithm **NEW**
  • All Pairs Shortest Path, Floyd-Warshall Algorithm **NEW**
  • Shortest Path A*
  •  Bi-directional Dijkstra Shortest Path **NEW**
  • Bi-directional A* Shortest Path **NEW**
  • Shortest Path Dijkstra
  • Driving Distance
  • K-Shortest Path, Multiple Alternative Paths **NEW**
  • K-Dijkstra, One to Many Shortest Path **NEW**
  • Traveling Sales Person **NEW Implementation**
  • Turn Restriction Shortest Path (TRSP) **NEW**
  • New functions for creating routing topology
  • New functions for analyzing a graph for problems


GeoServer 2.4 Released

Another significant release done at FOSS4G 2013 is the open source GeoServer 2.4. Along with MapServer, GeoServer is a popular server to disseminate geospatial data in WMS, and other standards of the same family.

Since I failed to find a nice list of what's new specifically for version 2.4, I feed you with a reminder of what GeoServer is according to their front page: "GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. [...] GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web."

QGIS 2.0 Released

This is major news. The popular open source desktop GIS formerly known as Quantum GIS, now simply QGIS, has released its version 2.0 at FOSS4G 2013. This release reduces the gap with some of the mature commercial desktop GIS available. There's also QGIS 2.0 for Android in the works.

Here's the full list of what's new and changed - it's just too long to copy it all, so here's some of it:

User interface:

  • Feature: Side tabs, collapsable groups
  • Feature: Soft notifications
  • Feature: Drag and drop form builder

Data providers:

  • Feature: Oracle Spatial support
  • Feature: Web Coverage Service (WCS) provider added
  • Feature: Raster 2% cumulative cut by default
  • Feature: WMTS Support


  • Feature: Data defined properties
  • Feature: Support for transparency in colour definitions
  • Feature: Color Control for Raster Layers

Map composer:

  • Feature: Multipage support
  • Feature: Layer blending
  • Feature: Multicolumn composer legend


  • Feature: Expression based label properties

There's a lot more to it. Head to the full list to learn more and see numerous screenshots.

U.S. Synthetic Population Viewer Released

I thought this RTI-developed web-based synthetic population viewer would be of interest to some of you.  It allows users to explore the amazing diversity of human household population distributions in the United States. The viewer enables the user to see synthetic households by income, race, size, and age. These synthetic populations form the agents for many ABMs, but aside from that key purpose, they also provide a rich basis to explore the demographics of the United States as illustrated in the viewer.  Over 112,000,000 households are at your fingertips.

Most interesting to look at are large cities—NY, Chicago, LA, DC, etc.  Be sure to try it in ‘Quad View’ and with a Black background!

Do a Map, the fastest way to create and share a map

Do a Map is an easy internet service to create a map and share it with your friends or customers, include it on a website or blog or publish it on the main social networks (Facebook, Twitter, ...).

The main property of this service is how quickly  you can create a map: no account, no registration, no verification emails.  Just accessing to Do a Map, the user can draw and share maps on most popular social networks in less than a minute.

For example, the restaurant position where you are going to meet your friends, or the place where you are going to meet with a client.

Do a map has a simple editor to draw polygons, routes or add markers to the map. As easy as draw on a blackboard, we can draw elements, remove them and create them again, to make simple maps with some makers or completed ones adding polygons and routes.

Once created, you just have to save the map and you get a map link to share it or use it like you want: add a map to your own web or blog, share it on Facebook or Twitter, send the map link by mail or whatsapp… 

In summary, Do a map is an excellent solution to create quickly (and in an anonymous way) maps on internet.


Slashgeo is Media Partner of 'Geomatics 2013' in Montreal, October 3-4

I'm happy to announce Slashgeo will be a proud media partner of the 'Geomatics 2013' event in Montreal, to take place on October 3 and 4. We've been a media partner of the 'Geomatics 2011' event and I have personally missed it only once since year 2000 (I missed it because I was at the FOSS4G conference!).

The recurring Geomatique 20XY event in Montreal is the conference to attend in the Quebec province. It attracts about 700 participants. While most of the presentations are done in French, mostly everybody attending speaks English (Montreal is in North America after all ;-). From their main page: "Geomatics 2013 is:

  • The most important event in Quebec’s geomatics industry, gathering close to 700 participants;
  • Dynamic speakers who will present their accomplishments and discoveries in the field of geomatics;
  • A vast commercial exhibition featuring over 40 exhibitors including key actors in the fields of equipment,
  • software and services;
  • A showcase of new technologies;
  • Two conference lunches featuring prestigious speakers;
  • And a networking event that is always highly awaited!"

I'll be on-site myself, and will give a presentation related to my real day job, the official worldwide weather and radar layers available in WMS and KML for free.

OpenGeo Relaunches as Boundless

OpenGeo is one of the few major open source geospatial companies out there and we mention them frequently. Today OpenGeo announced that their future is not just open, it's boundless, OpenGeo is rebranding and will now be known as Boundless.

From the announcement: "With the momentum behind our company and shifts happening within the industry, we realized that we needed a new identity to better reflect where we’re headed. We also recognized that there are potential conflicts with other companies using the OpenGeo name, driving a desire for us to build a larger, more encompassing brand for our vision and products. [...] While we’ll be developing new solutions and taking on new challenges, we’re not leaving our current products behind. In fact, we’re expanding them. Our new name marks our push into new technologies, including geospatial web services monitoring with Mapmeter, desktop software with QGIS, our growing capabilities in cloud and mobile platforms, and our expanded work in data editing workflows."
