Case studies

The Directorate General of Transport needed a GIS application to display all bus routes passing through Valencian Community (Spain). It had to include all bus stops which those bus routes have and the companies which manage them.

The night pictures taken from the International Space Station (ISS) and other NASA missions as DMSP can be used to compute light emission from ground based locations. We need a complete GIS toolkit to study correlations among the satellite images and light sources. So we can get information about individual buildings or geographical areas.
We need also a tool which can use standard OGC services to access Geographic information and Layers from other SDI (Spatial Data Infrastructure), as IDEE. The connection to spatial databases, as PostGIS, would be the last requirement.

The regional government of Andalusia (Junta de Andalucía) used gvSIG as its GIS desktop tool and their technicians used gvSIG to access dozens of geographical layers. The usual way to load layers on gvSIG had some difficulties because the sources are multiple and discovering them is not always easy.
