gvSIG Association - i3Geo. Connecting liberties

The headline of this press release would be able to be that i3Geo becomes an official product of the gvSIG project, but the true importance of this passing is that i3Geo and gvSIG join their forces, a summation of efforts based on similar ways to understand opens source as something that goes beyond technical questions. With this agreement there's an approach to collaborate in a model level. We expect to grow in the technical, economic and organizational parts through the collaboration between projects that bet on open source as fundamental base for technological independence, that understand the software as a means and not as an end. At the free geomatics area, i3Geo is without doubt the reference of technology with Latin American origin. i3Geo was created by the Environment Ministry (MMA) in Brazil, in the context of the implementation of the National Information System about Environment (SINIMA). Its license was changed to GPL in, and it became a part of the Brazilian Public Software Portal (PSPB).

i3Geo, that means "Geoprocessing Tools Integrated Interface for Internet", was born with the objective to create a software that allowed the dissemination of geographical data and gave more advanced options to the final user. The software has evolved, adding new functionalities; among others, the software allows the user to access to the attribute table of the layers, load data, connect to OGC services, change legend by default, interact with other data (Wikipedia, Confluence, Metar, etc.), vector editing, geoprocessing... Furthermore, i3Geo offers direct access services like downloads, WMS, WFS, KML and KMZ, making the implementation of SDIs easy.

These circumstances took to the integration of i3Geo with gvSIG in two ways too. Firstly with a plugin that allows to the same catalog to be shown in gvSIG to include the layers in the project, that is to say that the same organization of the data is shown in the interactive layout in the website and in a gvSIG project. Secondly, a PHP class that allows the projects to be read by i3Geo, working as a desktop application to create maps that will be published in the website.

In this agreement, Edmar Moretti, main developer of i3Geo, becomes part of the gvSIG Professional Structure. In short, the integration between the i3Geo and gvSIG communities will bring growth opportunities for both of them. Growth of the free technical offer that the gvSIG project hosts, growth as community and in the community. Communities that grow in an inclusive way, with affinity to a values and a job oriented to connect liberties, solutions and efforts.

Our strength is the growth and the peer organization: i3Geo and gvSIG.

gvSIG Community Edition Technology Preview

An early preview of the upcoming gvSIG Community Edition 1.0 is available for testing.

[Editor's note: let me paste below the "press release" that was submitted and approved on this very topic]

gvSIG Community Edition TECHNOLOGY PREVIEW available for testing

An early preview of the upcoming gvSIG Community Edition 1.0 is available for download here.
It is not intended for use in a production environment. We expect that there are still missing features in this release. In particular, the following features are NOT YET included:

  • updated 32/64 bit binaries (raster drivers)
  • GRASS and SAGA GIS binaries (via SEXTANTE)
  • third-party extensions (e.g. OpenCAD, NavTable)
  • the new extensions manager tool

We have included a SEXTANTE snapshot from 08/28/2011. Functionalities of GRASS GIS and SAGA can be added to the SEXTANTE Toolbox following the instructions of this document. You will see all the available raster- and vector tools from SEXTANTE, SAGA, GRASS GIS and gvSIG CE which all together are currently 760 algorithms.
A continuously updated release announcement, detailing the progress on new features and bug fixes can be found here.
This is a zero-install distribution. Simply unpack it somewhere on your hard disk and start it:

  • Linux: start bin/gvSIG.sh
  • Windows: start bin/gvSIG.bat
  • Mac OS X: double-click the App folder

Please report your findings to our users mailing list.

Here's the recent geonews that we haven't mentioned yet, in batch mode.

On the open source front:

  • You can now animate your maps with the GeoServer WMS Animator Tool
  • Here I found out about oculu-Z, an open source, open data platform for collaborative Computer Vision technology
  • Want to know where OpenStreetMap is heading? Read this entry on the OpenStreetMap Foundation Board. Related to OSM, TripAdvisor now uses OpenStreetMap
  • DM shared the first of a series of articles on open source geospatial software in the classroom, called Open Source Desktop GIS: Let’s Get Started
  • APB mentions the Ushahidi2ArcGIS prototype, which imports Ushahidi data into ArcGIS
  • I could only smile when I learned about the PostGIS Day, a day after 'GIS Day'
  • gvSIG shares 60 new case studies

In the everything-else category:

  • APB reports about an estimation of Esri's worldwide market share at 40.7% in 2010
  • MapQuest wants to make certain we know that they don't have preset limits on their free Map API transactions
  • DM shares an article named Effective Offshore GIS Data Management Services
  • SS informs us that Trimble launched custom printed maps with MyTopo, for the U.S. and Canada

GGL Geoprocessing language available in gvSIG


As results of the Google Summer of Code at the gvSIG project, the gvSIG plug-in for GGL has been released [1].

GGL is a specific programming language for geoprocessing where typical constructions of the more known programming languages (loops, conditionals, etc.) and specific constructions for geoprocessing to execute topological operations, filters, transformation of geometries, etc. adding help at the same time that the user write the scripts.

The released plug-in allows to reference the data sources of the project open currently in gvSIG Desktop from the GGL scripts, making the geoprocessing of the data loaded in gvSIG possible. Anyway, the plug-in allows to visualize return results in gvSIG Desktop loading the same ones at the active view.

Apart from the plug-in, several tutorials and reference documents [2] have been published to understand the logical language.

Likewise, some mailing lists [3] have been created to solve any problem or doubt when the system is used.

The advantadges of using a geoprocessing specific language are:

  • The mencioned geoprocessing specific constructions: geometries in WKT, coordenates processing, typical operators of the relational algebra that add the same capacities than the spatial SQL to the language, etc.
  • Help for creating scripts: Validations at the same time that the user writes, verification of the existence of the data sources and accesed data structures, autocompletion with the fields of the accessed files, etc.
  • Pre-selection of technologies: GGL offers a series of functions to the user, that use the best internal technology currently: parsers, data access API, etc. That technology is pre-selected by the language developers, and it's a less responsability for the user, who only has to specify the operation and not how to execute it.
  • Possibility to repeat geoprocesses, share them, give support, etc.
