What is Geospatial Mapping?
Geospatial mapping differs from traditional maps in that computerized data is provided for the user to create a custom map suited to their particular needs. Some of these data sets allow the user to create a map on the site, others require that the data be downloaded into a separate software program. Geographical Information Systems (GIS) are software products which can be used to manipulate and analyze this data. The resources listed below are suitable for use by the non-expert.
