This document discusses the application of Geographic Information Systems (GIS) for various purposes:
1) GIS is used for disaster and emergency management like mapping earthquakes, cyclones, landslides, floods, and fires. It allows for relief and rehabilitation efforts to be planned.
2) GIS enables crime mapping and prediction by analyzing patterns of past crimes.
3) Other applications include GIS-based analysis of parking availability, deforestation over time, and generating contour maps and studying topography.
