DIVA-GIS is a free computer program for mapping and for analyzing spatial data. It is particularly useful for analyzing the distribution of organisms to elucidate geographic and ecological patterns. It is aimed at persons who cannot afford generic commercial geographic information system (GIS) software, or do not have the time to learn how to use these, and for anyone else who wants a GIS tailor-made to analyze biological distributions. DIVA-GIS supports vector (point, line, polygon) and image and grid data types. DIVA-GIS can help improve data quality by finding the coordinates of localities using gazetteers, and by checking existing coordinates using overlays (spatial queries) of the collection sites and administrative boundary databases. Distribution maps can then be made. Analytical functions in DIVA-GIS include mapping of richness and diversity (including based on molecular marker (DNA) data; mapping the distribution of specific traits; identification of areas with complementary diversity; and analysis of spatial autocorrelation. DIVA-GIS can also extract climate data for all locations on land. Ecological niche modeling can be carried out using the BIOCLIM and DOMAIN algorithms.
