Open Source Community GIS Software
Alvaro Anguix writes "In the past, we always said that gvSIG has the purpose of cover every needs regarding the use of the geographic information by the integration of free technologies. Following this roadmap, we can see gvSIG as a platform for the full-manage of the geographic information. Thus, every user can install the set of tools desired. One of the working areas is related with the raster GIS and teledetection. It is inspired by this way-to-do and approaches the vector GIS to the raster GIS. Now, we release the pilot of the company which won the public tender to develope the raster extension of gvSIG that allows to open new image file formats, apply color palettes to a DTM, the generation of histograms, to cut raster layers and define some new rendering filters. We'd like also report the next release of the new module for the manage of CRSs (Coordinate Reference Systems), that features the possibility of CRS's databases (complete EPSG, IAU2000, and others), transformations of 3 and 7 parameters and transformations based upon a grid, and in general to get a maximum precision in CRS reprojections Both extensions can be found in the http://www.gvsig.gva.es/index.php?id=1566&L=0. They are designed as regular extensions that can be plugged in to any of the gvSIG 1.0 stable versions (gvSIG 1.0.x) Regards Alvaro Anguix IVER TI SA www.gvsig.com www.iver.es" Alvaro previously informed Slashgeo readers about gvSIG.

gvSIG 1.0-stable Released [+]
Alvaro Anguix writes "gvSIG, the Open Source (GNU/GPL license) Geographic Information System developed by the Generalitat Valenciana reaches its version 1.0. With this release, gvSIG presents itself as an integrated GIS + SDI (Spatial Data Infrastructure) client, able to combine data from different local and remote sources (web services) and at the same time include advanced editing, geoprocessing, scripting language support and georeferencing among other features. All the details about this release, as well as the source code and the binary files, can be found in the project web site www.gvsig.gva.es. The project is currently funded by the European Union (FEDER funds), which guarantees its continued evolution. Among other pending tasks, a road map of future gvSIG development will be published soon. gvSIG counts with a large user and developer community registered in the mailing lists, true engines of the project. Through these lists, technical and other support is provided, and they serve as the glue that keeps together the community by practicing the open source philosophy of sharing our knowledge. We encourage you to suscribe to these lists and to communicate through them all your questions, criticism and suggestions, which make possible that the project stays healthy and growing."
Technology: gvSIG Now Connects to Oracle Spatial [+]
Alvaro Anguix writes "geoBD extension that allows access to spatial databases, modifying the old interface to access them is available in gvSIG. It also provides the Oracle Spatial connector to the spatial database connector already existing (PostGIS, MySQL, and HSQLDB) allowing the user to access to a any table from either Oracle Spatial or Oracle Locater (since Oracle 9i) containing a geometry column of type SDO GEOMETRY.

It is available in the Extensions (http://www.gvsig.gva.es/index.php?id=1652&L=2 <http://www.gvsig.gva.es/index.php?id=1652&L=2>) option from the Downloads section of the web page. Advice: To install this extension you must have correctly installed gvSIG 1.0.2 version.

Technology: Sextante Analysis Suite for gvSIG Released [+]
The Geowanking list informs us Sextante, an analysis suite for the open source gvSIG GIS, has been released as open source as well. The new, in Spanish only for the moment, is here and the previous story about gvSIG here. From the press release: "The aim of this suite is to add advanced spatial data analysis capabilities to gvSIG (http://www.gvsig.gva.es), for both raster and vector data. The suite comprises 161 extensions, including modules dealing with geostatistics, geomorphometry, hydrology or point pattern analysis, among others, along with basic raster and vector data handling utilities. [...] Both the website and the software are only available in spanish, but english versions are on its way." See related stories below for gvSIG announcements.
Technology: gvSIG 1.1 Released [+]
The open source GIS gvSIG 1.1 has been recently announced. All Points Blog explains the buzz around gvSIG: "- The team includes two rather large main contractors and a host of smaller ones. There are also volunteers. That's about 40 developers, with total staff (including management) at about 70-80. - The current funding includes E12 million that runs from 2007 until 2013. - There are 1000 subscribers on the project list, and the project has been downloaded 70,000 times. - The plan for success included the idea of starting small, proving the result worked and growing the project from there. The guiding principle is "we have to share knowledge" and the group is anxious to show the success of this new model for collaboration." See below for previous gvSIG coverage.
gvSIG Update Version 1.1.1 and 3D Pilot Extension [+]
Alvaro Anguix writes "gvSIG 1.1.1, a partial update of gvSIG 1.1, is now available for download in which some problems detected by our users have been fixed, so it is possible to working normally with the application. As usual, it can be downloaded from the Download section of the web page. The problems fixed in this distribution can be checked from the Release Notes Section and to install the partial update you must have gvSIG 1.1 correctly installed. On the other hand, the pilot application awarded the development contract for the 3D Extension by the Regional Ministry of Infrastructure and Transport is available too. It allows the creation of 3D Views, XYZ-projected as well as spherical (planetary), where local and remote data sources can be loaded as layers, and displayed using most of the options available in 2D like transparency, labeling, legends, etc. It's available in the Extensions section of the web page and to install this extension you must have correctly installed gvSIG 1.1.1 version." I copied below several previous stories on the open source GIS gvSIG.
