I' m looking for stuff and advice about GIS (Geographic Information System).
Google can give me stuff, so I' m asking for advice (but stuff too) about integrating GIS with VFP.
Mainly, I' ve the need of extracting information from Esri-shapefiles from two different files and be able to determine the common area (if exists) between the two polygons: one belonging to the first shapefile and one (polygon) to the second, which may or not (or partially) cover the first one.
TIA
