gvSIG Desktop is a powerful geographic information system (GIS) designed
to offer a free and user-friendly solution to all needs related to geographic
information management. It is characterized as a comprehensive, easy to use solution,
it adapts to the needs of any GIS user. Access to the most common formats, both
vector and raster, both local and remote is possible. It integrates with Open Geospatial Consortium (OGC) standards,
and has a large number of tools to work with geographic information
(visualization, mapping, geoprocessing, networks, etc.). All this features make
gvSIG an ideal tool for users working with the territorial component.
In gvSIG, the first part of the
abbreviation (i.e. gv) stands for Generalitat
Valenciana, the Spanish regional authority that the system was originally
developed for. The latter part, SIG, is the Spanish equivalent for the English GIS.
Some of its main features are:
- Portable: runs on different hardware / Operating System (OS) such as Linux, Windows (32/64 bits) and Mac OS. The programming language is Java.
- Modular: is extensible with new functionality through the development of extensions/plug-ins, allowing a continuous improvement of the software as well as the development of custom solutions.
- Open Source: under the GNU/GPL license, allowing free use, distribution, study and improvement.
- Interoperable with solutions already implemented: it can access data from other proprietary programs, including ArcView, AutoCAD or Microstation without data conversion.
- Multilingual: is available in more than twenty languages (Spanish, English, German, Italian ,...) and allows the addition of new languages easily.
- Standards: Integrating in the same view both local (files, databases) and remote data through OGC standards such as Web Map Server (WMS), Web Feature Server (WFS) etc.
Main types of functionalities
provided by gvSIG are:
- Vector: Access to vector formats, databases, navigation, query, selection, analysis and geoprocessing, graphic editing and alphanumeric symbology, labeling, cartographic layout, data conversion to other formats and projection systems, relationships between tables, statistics, normalization, ...
- Raster and remote sensing: access to raster formats, color tables and gradient, cropping of data and bands, and export layer, pixel processing, color processing, overviews generation, radiometric enhancements, histograms, raster reprojection, georeferencing, automatic vectorization, bands algebra, defining regions of interest, supervised and unsupervised classification, decision trees, fusion of images, mosaics, scatter diagrams, ...
- Spatial Data Infrastructures and standards: access to remote services using OGC standards (WMS, WFS, WFS-T, WCS), access by non-standard services (ArcIMS, ECWP) catalog search service, gazetteer service, access standard file formats, OGC publishing extension, ...
- 3D: 3D view flat, spherical 3D view, support all formats and remote services, elevation layers, vector layers with heights, 3D layers, direct visualization of vector layers or through the rasterization of vector layers, 3D symbols, extrusion vector layers, georeferencing and editing 3D objects, 3D frames, 3D Animation system, selection, information, stereo visualization (anaglyph, horizontal split, etc), full-screen display, geographical search by name (gazeeteer ),...

Sir, your page is so informative. I have attended one lecture of yours in j. u architecture department last December. But due to lack of practise, is about to forget the detailing. Thank god, i have this blog now. Thank you so much sir
