gvSIG is a Geographic Information System (GIS), that is, a desktop application designed for capturing, storing, handling, analyzing and deploying any kind of referenced geographic information in order to solve complex management and planning problems. gvSIG is known for having a user-friendly interface, being able to access the most common formats, both vector and raster ones. It features a wide range of tools for working with geographic-like information (query tools, layout creation, geoprocessing, networks, etc.), which turns gvSIG into the ideal tool for users working in the land realm.
To run gvSIG on the Live DVD, click on the gvSIG icon on the desktop.
gvSIG can load lots of local data (raster and vector formats) as well as any OGC service (WxS) and other propietary formats like ArcIMS or Oracle databases. Open gvSIG, create a view, set up your working projection (view properties) and start adding geodata with the View->Add layer dialog.
You can load several shapefiles and images from /usr/local/share/openjump-data or /usr/local/share/qgis-data as well as any other sample data loaded or OGC service configured on the disc.
There is a sample project at /home/user/gvSIG/sample-project.gvp folder. You can load it with gvSIG and see some sample styled data as well as a sample map.
You can look for help at user documentation on gvSIG English Manual (PDF). Note that this manual refers to 1.1.2 version as 1.9rc1 doesn't have at this time a published manual of new features. Visit the gvSIG community website at http://gvsig.org for more updated manuals and docs.
