In order to generate the maps in CrimeBase, we use
Geographic Information Systems (GIS)
data provided by the City of Philadelphia. If you would like to combine data you have
exported from NBase with GIS data, you may use the shapefiles provided below. The
ESRI shapefiles format can be read using a broad range of GIS software.
Additional GIS data for the City of Philadelphia is available at
the Commonwealth of Pennsylvania's spatial data clearinghouse.
