The revised AGI online GIS dictionary is a major enhancement of the original version developed during 1996 by the University of Edinburgh's Department of Geography.

Although the full range of functions are only available to AGI members, its facilities go well beyond those that were available in the original version.

The dictionary includes definitions for 980 terms compiled from a variety of sources which either relate directly to GIS or which GIS users may come across in the course of their work. The dictionary is also supplemented by 52 diagrams.
