Processing of Aerial Photos,p to date GIS databases. Aerial photos can be used to extract georeferenced data representing topography, landforms, vegetation cover as well as man-made features. Digital processing of aerial photos in GRASS allows the user to incorporate aerial photos into a GIS database.

Open Source Software and GIS,roblems related to urban and regional planning, environmental protection, or business management, require sophisticated tools and special expertise. Therefore the current GIS technology spans a wide range of applications from viewing maps and images to spatial analysis, modeling and simulations.
