Map Layers On CD

If you are using the RiverGuid on CD-ROM, rather than on the OHTMC web site, you do not have to download RiverGuide GIS Map Layer files.  They are already located on the CD-ROM here:

[CD drive]:\GIS\Layers\

When you open up the RiverGuide GIS Project inside ArcExplorer, the Map Layers will aready be pre-loaded into the Project.

If you choose to copy the Map Layers files to your hard disk, you will need to tell ArcExplorer where to find them by using the Add Themes (Layers) button and indicating the correct folder.

(Contact Old Harford Town Maritime Center to obtain a RiverGuide CD-ROM.)
