Using gvSIG to compute light pollution from night satellite images

Light pollution (introduced by humans, directly or indirectly, from artificial light into the environment) is a major issue worldwide, particularly in urban areas. It increases the sky glow and prevents us from observing a dark starry sky. There is also a direct relationship between light pollution and electric consumption.

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.
