Professor Ganapati traces the evolution of the use of Geographic Information Systems (GIS) in government, with a focus on the use of GIS by local government. The current third wave (Geospatial Web 2.0 platforms) has seen a dramatic increase in the use of GIS by citizens, such as obtaining transit and crime information. Professor Ganapati presents several case examples of how GIS is now being used by local governments across the nation.
