Using remote sensing software can yield highly accurate maps of the urban and Wild-Land interface. The picture below uses hyper-spectral satallite imagery to differentiate between materials on earths surface and groups them together according to your application.

This Map was made using aerial and satellite photography. The images were analyzed using ENVI; a remote sensing software,which produced the resulting data of urban growth over the past 5 decades.
GIS software is a powerful tool to map out fuel loads. This map was later used to compute fire hazard maps for the Santa Barbara County Fire Department.
