Open Source Geonews: OSGeo about 20,000 Strong Now, FOSS4G Wrap-Ups, GrassrootsMapping, and much more

Here's the recent open source geospatial news in batch mode, which includes everything about FOSS4G on the geoblogs that we haven't mentioned yet.

On the FOSS4G Conference front:

  • Interesting numbers, "By there are now 19,471 unique subscribers to OSGeo, more than 400 mailing lists, and more than 15 million lines of code, with 740 contributors, and 269 that have contributed for more than 12 months."
  • Slashgeo editor Nicolas summarized Brian Timoney's excellent talk at FOSS4G, and if you want to hear it yourself, here is that 14-minutes impassioned talk on the state of the geospatial industry, Brian demonstrate how much better we could do
  • Here's the slides of Paul Ramsey's keynote
  • Here's Jody Garnett's updated slides on the WPS Shootout
  • Here's the entry to read about Open Source and Open Data at the U.K. Ordnance Survey
  • If you haven't read too much about it already, here's an entry on the case study of the U.S. FCC National Broadband Map based on open source geospatial software
  • Here's the what's coming to PostGIS 2.0 slides [pdf]
  • I heard comments that 30-minutes talks at FOSS4G was too short for the presenters to dive into their subjects, would you agree? If you're interested in what could be improved see this recap of FOSS4G by OSGeo's president
  • Here's Directions Mag complete wrap up of the conference

In other news:

  • I was surprised to read that Tyler Mitchell won't be the OSGeo Executive Director anymore
  • GWT-OpenLayers version 0.6 has been released, that's the wrapper library for using OpenLayers in Google Web Toolkit applications
  • MapFish is now an official OSGeo project
  • This entry reminds us of the comprehensive list of web mapping toolkits (there's too much of them!)
  • SS mentioned GrassrootsMapping, which is a crowdsourcing aerial image project with goals similar to OpenAerialMap

GeoGit - Git for Geospatial

You probably know what Git is, the modern distributed revision control system, replacing CVS and Subversion for many projects. Spatially Adjusted made me aware of the GeoGit approach.

Here's what the documentation written a month ago says: "Following on the core Versioning WFS work, in OpenGeo started experimenting with a new way to handle versioning, drawing on git, a distributed versioning system built for Linux and widely used. There are two different paths taken, both of which warrant further investigation:

  • Using git and github directly, storing data as geojson in files
  • Drawing inspiration from git core code and adapting the structures to work with geospatial information


The code for the core repository can be found at  . This code backs both a GeoSynchronization Service module (a spec by the OGC to synchronize data) and the versioning constructs of WFS2. The plan is to eventually get both in to the standard distributions of GeoServer.


For the geogit implementation we instead code things to be optimized for the fact that a typical geospatial representation doesn't have much nesting - it's just a bunch of features. The index is orthogonal, doesn't need to be part of the tree structure. But the problem we had when we tried to use straight git with lots of leafs is that it wouldn't really work. It doesn't scale to a single directory with millions of files."

GeoMondrian SOLAP Server 1.0 Released

We mentioned it over two years ago and now it reaches a major milestone, the open source SOLAP server GeoMondrian 1.0 has been released.

What is GeoMondrian? "GeoMondrian is an open source Spatial OnLine Analytical Processing (Spatial OLAP or SOLAP) server, a spatially-enabled version of Pentaho Analysis Services (aka. Mondrian). As far as we know, it is the first implementation of such a server and it is open source! [...] GeoMondrian provides then a consistent integration of spatial objects into the OLAP data cube structure, instead of fetching them from an external spatial DBMS, web service or a GIS file. To summarize, GeoMondrian brings to the Mondrian OLAP server what PostGIS brings to the PostgreSQL DBMS, i.e. a consistent and powerful storage and querying for geospatial data!"

OpenTreeMap: Open Source Software for Collaborative Geography-Enabled Urban Tree Inventory

Via Datalibre, I learned about OpenTreeMap, an open source software for collaborative, geography-enabled urban tree inventory.

From the main site: "Urban street trees have myriad proven benefits for communities including providing shade, improving air quality, assisting with stormwater runoff, raising property values, decreasing utility bills, and enhancing the look and feel of communities. While tree inventories provide municipalities with vital data to consult when managing the urban forest, creating a complete inventory is a time consuming and resource intensive process.  OpenTreeMap provides an easy-to-use public inventorying platform that enables individuals, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population. OpenTreeMap can be used in a single municipality or cover a broader geographic region with many communities.

Main Features:
  • Search for trees by species, location, or advanced filters such as diameter, date planted, or tree characteristics (flowering, native, etc.)
  • Add trees individually or load tree datasets to the system
  • Edit and add information about existing tree records including species name, location, height, plot size and type, conditions, actions needed, funding sources, data owner
  • Upload tree photos
  • Export tree lists as KML or CSV files
  • Automatically calculate ecosystem benefits (greenhouse gas, water, energy,  air quality) based on a tree’s species and diameter
  • Monitor user accounts, comments, and system edits
  • Get optional integrated tree key to assist in identifying tree species"

Geocoded trees have been mentioned a few times in the past, including Google Earth 6's native support of 3D treesusing lidar to identify urban trees, or even embedding RFID tags in trees.

MapQuery 0.1 Released

Via the OSGeo-Discuss list I learned about the release of the open source library MapQuery 0.1. Here's the official mapquery website.

What is MapQuery? "MapQuery is a pure javascript based library which builds upon OpenLayers, jQuery and jQuery UI to provide an easy to use webmapping library. It is meant for jQuery application developers who want to build Rich Internet Applications (RIAs) with maps. Currently it provides a few basic widgets to create functionality around a map and an easy API to write your own widgets."

Here's more on its goals: "MapQuery formally extends OpenLayers, it is similar in concept as GeoExt, but uses jQuery instead of Ext. The idea is to create a jQuery-style webmapping library which wraps around OpenLayers and extends it with functionality like layer managers, datagrids (NYI), legends etc. We try to make it easy to create a webmap-application with OpenLayers, without having to know all that OpenLayers has to offer.

We aim at jQuery developers more than on people who are already well-versed in OpenLayers. As such we will provide a few simple functions which (we think) will be enough for 90% of the use-cases. The other 10% is not actively pursued, though one could directly access OpenLayers and do some of the advanced stuff we're not providing."

Open Source ETL Tools: GeoKettle 2.0 and Spatial Data Integrator 4.2.0 Released

Last week was announced GeoKettle 2.0, an open source spatial ETL (extract transform and load) tool. 

From the announcement: "GeoKettle, as its name suggests, is based on the widely used and robust generic ETL tool Kettle (aka Pentaho Data Integration or PDI) made « geo-capable » by integrating and leveraging the power of geospatial libraries such as of JTS, GeoTools, OGR, deegree and of course, brand new Spatialytics code." Here's the details of what's new for version 2.0. We mentioned quite a few times GeoKettle the past three years.

There's another open source spatial ETL tool out there that we haven't mentioned for a while, it's Talend's Spatial Data Integrator, with its version 4.2.0 released earlier this month. 

From their main page: "Spatial module for Talend Open Studio (aka. Spatial Data Integrator or SDI) is an ETL with geospatial capabilities. Likewise regular TOS components, there are basically three sorts of Geo components: input, output and transform components. Input and output components read features from and write feature to datastores, respectively. Transform components read features from their input flows, possibly transform those features, and write features to their output flows. The term transform is to be taken loosely here as it represents any sort of operation."
