- To provide a gridded version of existing vector maps of amphibian species distribution at 1- kilometer that preserves the original coding (1=Extant, 2= Possibly present, 3=Probably extinct, 4=Extinct, 5=Extirpated purposely, 6=Occurs on indicated island chain, and 7=Subfossil/fossil).
- The Global Amphibians Original Grids of the Gridded Species Distribution, Version 1 are converted 1- kilometer grid cell data available in the Geographic Coordinate System (GCS). The input vector data were created by a consortium led by Natureserve. The grids are produced by the Columbia University Center for International Earth Science Information Network (CIESIN).
