Prof. Qiming Zhou Usage of GIS software The estimated regular GIS users (sites) in 2005. If Internet GIS users were included, the total usage of GIS software rose to about 10 million, excluding users of GIS products such as maps, charts and reports.

Prof. Qiming Zhou Summary GIS software is a fundamental and critical part of any operational GIS. Today there are many types of GIS software product to choose from. There are also a number of ways to configure implementations. The development of GIS software has now a very rapid rate. GIS Software GIS Software
