Convert Binary Species Range Maps into Continuous Surfaces Based on Distance to Range Edge

Contains functions to convert binary (presence-absence) expert species range maps (like those found in a field guide) into continuous surfaces based on distance to range edge. These maps can then be used in species distribution models such as Maximum Entropy (Phillips 2008 ) using additional information (such as point occurrence data) to refine the expert map.
