The AGISRS list informs us of new species distribution grids data available. From the announcement: "NASA's Socioeconomic Data and Applications Center (SEDAC), based at CIESIN, has gridded nearly 12,000 species distribution maps which were originally in vector format (ESRI shapefile). The original data were developed by a consortium of conservation organizations including NatureServe, IUCN, Conservation International, and World Wildlife Fund-USA. To make these data more useful for modeling and for integration with socioeconomic and other data, SEDAC converted the entire collection of shapefiles to raster format. This newly released Web site provides a search facility for quickly locating and downloading 1-kilometer (30 arc-second) resolution grids of selected species maps in GeoTIFF format. Data are available for global amphibian distributions, and for birds and mammals in the Americas. The Web site provides access to individual species distribution grids, along with family grids that show the density and distribution of species within a given family."
