DIVA-GIS is a free computer program for mapping and geographic data analysis (a geographic information system (
GIS). With DIVA-GIS you can make maps of the world, or of a very small area, using, for example, state boundaries, rivers, a satellite image, and the locations of sites where an animal species was observed. We also provide
free spatial data for the whole world that you can use in DIVA-GIS or other programs.
DIVA-GIS is particularly useful for mapping and analyzing biodiversity data, such as the distribution of species, or other 'point-distributions'. It reads and write standard data formats such as ESRI shapefiles, so interoperability is not a problem. DIVA-GIS runs on Windows and (with minor effort) on Mac OSX (
see instructions).
You can use the program to analyze data, for example by making grid (raster) maps of the distribution of biological diversity, to find areas that have high, low, or complementary levels of diversity. And you can also map and query climate data. You can predict species distributions using the BIOCLIM or DOMAIN models.

The datasets contained in this website are part of the International Centre for Tropical Agriculture (CIAT) and The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). CIAT is an agricultural research institution, focused on scientific solutions to hunger in the tropics. CIAT believe eco-efficient agriculture—developing sustainable methods of food production—is the best way to eradicate hunger and improve livelihoods in the region. CIAT is a leading not-for-profit organization and we have been helping smallholders grow more food and earn more money for 40 years.
