ESRI Resources Under Your Nose

ESRI provides some very useful general GIS datasets with its ArcView 3.2 and ArcGIS 8.2 software which are installed during the general installation process.  As far as I know, all of these data are in geographic coordinates.  Their location will depend on where the person who ran the installer specified the software was to be installed. 

On my machine, the following useful datasets are stored in the directory C:\ESRI\ESRIDATA
