DIVA-GIS: Geographic Information System for Biodiversity Research
Entry ID: DIVA_GIS
Abstract: DIVA-GIS can be used to analyze the distribution of organisms to elucidate and ecological patterns. It is aimed at scientists who cannot afford generic geographic information system (GIS) software, or do not have the time to use these, and for anyone else who wants a GIS tailor-made to analyze biological distributions. DIVA-GIS can help improve data quality by finding the coordinates localities ... using gazetteers, and by checking existing coordinates using overlays queries) of the collection sites and administrative boundary databases. Distribution maps can then be made. Analytical functions in DIVA-GIS include mapping and diversity (including based on molecular marker (DNA) data; mapping distribution of specific traits; identification of areas with complementary and analysis of spatial autocorrelation. DIVA-GIS can also extract climate locations on land. Ecological niche modeling can be carried out using the DOMAIN algorithms (with predictions for current and future climates).

Quality DIVA-GIS is a relatively new program and not all parts have been tested
completely. This means that you should never blindly believe the results of
your analysis. Instead, you should always test if DIVA-GIS works well, for
example by manually calculating the expected results for a small number of grid
cells. Or by first doing the calculations with a simple sample data set for
which you know the results.
