Reviews:

Most GIS titles focus on the geography end, so it's refreshing to see an analysis which focuses equally on business applications of GIS results and strategies, coming with the authority of a member of the American Society of Photogrammetry and Remote Sensing, American Geophysical Union, and the New York City Chapter of Geographic Information Systems and Mapping Operations.
