ESRI has created an umbrella software program name called ArcGIS 9.2. Under this umbrella are several applications, namely ArcMap and ArcCatalog. However, depending on the license purchased, these applications have different tools. There are three levels of licenses: ArcView, ArcEditor, and ArcInfo. ArcView has the fewest tools and ArcInfo has the total package.
In addition to the different license levels, there are also additional extensions which provide even more functionality and tools.
At RMBL, most of the Barclay computers have ArcView installed, which allows for viewing, but not much geoprocessing. One of the computers in Barclay, GIS Workstation, has ArcInfo with Spatial Analyst, Publisher, and 3D Analyst Extensions. This level license with these extensions allows for a great deal of functionality and geoprocessing.
If you need the tools available with the ArcInfo license, be sure that you are working on the GIS Workstation computer.
If you are already using the GIS Workstation and these tools don't appear, first go to View > Toolbars > Make sure that 3D Analyst, Editor, Publisher, and Spatial Analyst are all checked. If they unavailable to be checked go to Tools > Extensions > Make sure that they are all checked.
If this does not work, please contact the GIS tech, since there may a license or key issue.
