The IUCN Red List of Threatened Species uses spatial data for the mapping of species. The spatial data is created in shapefiles and compiles of a standardise format of attributes. Each shapefile must contain taxonomic information, and contain information on the distribution status, sources and other details (see Oct 2012 metadata document). Below are some of IUCN Red List Tools, basedata and example polygon shapefiles:
The following documents and tools are available to help users to find their way around species mapping of Red List assessments:
IUCN Toolbox and Instructions (14 MB) - Includes the IUCN Red List ToolBox for ArcMap and instructions for the tools.
Basedata (geodatabase ArcMap 10.1 version, 500MB)
