There are a wide range of spatial software available some are free and some are quite expensive. Most have their strengths and weaknesses. This is by no means a comprehensive list:

Proprietary Software

ESRI (ArcMap, ArcGIS, ArcGIS Server) probably the most widely used GIS on the market in the public health sector



Idrisi is primarily a raster based and powerful GIS that can be used with remote sensing and climate modelling

Free Software and Tools

QGIS (Quantum GIS) perhaps the most widely used and robust of the opensource GIS software

SatScan is a widely used space time clustering application that has been widely used in public health

CrimeStat primarily used for crime and law enforcement but has some very good tools for space and time analysis and spatial statistics


Putting public health on the map
