If you have any questions regarding installing Arcview, ESRI can be contacted for technical assistance. The calls are free. Using 2 students per computer may help in walking the lesson. Using the pictures for overheads may also help. If you are running off a server you may want to install PTME to the server hard disk, which will allow the systems to run faster.
Students can draw the necessary data from the server hard disk.
The directory where they will be working from will change from the one listed in the lesson. Each county when listed will include some state data. The county data can be identified by the theme name that has the county name in front of it. When the state data is selected it will reflect all the state data, not just that data in only your county. Arcview is a complicated program that is complex in nature but can be run at a basic level.
