Gridded Species Distribution, Version 1: Global Amphibians Presence Grids
Entry ID: CIESIN_SEDAC_SPECIES_AMP_PRES

[ Update this Record ]

Summary
Abstract: The Global Amphibians Presence Grids of the Gridded Species Distribution, Version 1 is a reclassified version of the original grids of amphibian species distribution maps. The data include 1- kilometer presence/absence grids for individual species available in Geographic Coordinate System (GCS). The input vector layers were produced by a consortium led by NatureServe. The gridding and grid processing are done by the Columbia University Center for International Earth Science Information Network (CIESIN).

The data in Band Interleaved by Line (BIL) format are available from the NASA Socioeconomic Data and Applications Center (SEDAC).

Purpose: To provide a gridded version of existing vector maps of amphibian species distribution in which each grid cell is recoded to 1 (for present) or 0 (for not present) for use in modeling efforts.
