Primary species range map data to create the diversity maps on BiodiversityMapping.org are from the IUCN (mammals, amphibians, and cone snails) and BirdLife International and NatureServe (birds). Range maps for mammals, amphibians, and cone snails can be found at,
http://www.iucnredlist.org/technical-documents/spatial-data
Range maps for birds can be requested at,

Species richness for the maps on the BiodiversityMapping website was calculated with ArcGIS 10.1 and ArcGIS 10.2 using equal area grids (Eckert IV). In all cases, extinct species were removed, as were non-native distributions of extant species. Polygons listed with the attribute Vagrant were also removed. In cases where a species range was split into multiple subspecies, these were merged to create a range map for the full species.
Richness was calculated using a 10×10km grid. For each grid cell, any species that overlapped any part of the cell counted as a presence of that species.
Maps of amphibian diversity include the total species richness, major taxonomic Orders (Anura, Caudata, Gymnophiona), threatened species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps from the IUCN, July 2013 update.
Maps of mammal diversity include the total species richness, major taxonomic Orders (Cetartiodactyla, Carnivora, Primates, Eulipotyphla, Chiroptera, Rodentia), marsupials, threatened species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps from the IUCN, July 2013 update.
Maps of bird diversity include the total species richness (using breeding, non-breeding, and combined ranges), major taxonomic groups (non-Passeriformes, Passeriformes, Tyranni, Passeri), parrots, hummingbirds, threatened species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps for all the world's birds in BirdLife International and NatureServe (2013).
Maps of cone snail diversity include the total species richness, threatened species, data deficient species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps from the IUCN, July 2013 update.
Versions of many of the maps on this site originally appeared in the scientific article, "Global patterns of terrestrial vertebrate diversity and conservation" (PDF), published in the Proceedings of the National Academy of Sciences in 2013.
