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.

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).
