DIVA-GIS is a free computer program for mapping and analysing spatial data. It is particularly useful for analysing the distribution of organisms to elucidate geographic and ecological patterns. It is aimed at those who cannot afford generic commercial geographic information system (GIS) software, or do not have the time to learn how to use these often complicated programs, and for anyone else who wants a GIS tailormade to analyse biological distributions. DIVA-GIS supports vector (point, line, polygon), image and grid data types.
The site also contains downloadable GIS data sets.
