DESCRIPTION OF CD-ROMs

LandView III is a desktop mapping program which allows the user to display EPA-regulated sites and demographic and economic data from the 1990 Census. This information can be layered on the network of U.S. streets, water features, and political and census boundaries. It is particularly useful for addressing environmental justice issues.

COMMON TASKS IN LANDVIEW III

To begin:

1. Insert the CD-ROM
2. Double-click the LandView III icon
3. Click Continue at the LandView III screen
4. Click OK at the MARPLOT screen
5. When both have opened, LandView III will appear on top again. Do not exit LandView - simply click on the MARPLOT screen to get MARPLOT on top.
6. If MARPLOT is drawing a map with lots of detail, press Esc to stop it.

What is the county of interest?

It is useful to show that county on the map as a starting point (even if you are not analyzing the entire county).

1. From the View menu, choose Go to View.
2. Scroll down in the menu and select the appropriate county.
3. Click Go to View.
4. Again, press the Esc key if the map is too detailed.

What do you want to see on the map?

1. Go to the List menu and choose Layer List.
2. Click on the little box under the word Hide to clear all layers.
3. Next to States, click Show
4. Next to Counties, click Show with Names
5. Does the person want to see census tracts, places, various EPA facilities, roads, water, etc? Scroll down in the list and choose to Show, Show with Names, or Range.
   • Show with Names - will show the layer on the map and its name (or, for census tracts and block groups, the number)
   • Show - will show the layer on the map without names
   • Range - will only show the layer on the map when zoomed in to a certain range. This is important for fine detail. For example, if you choose to Show with Names for Roads, the map will be too cluttered to see anything - until you zoom way in. It's better to choose Range for Roads, so that they do not clutter up the map.
6. When all layers have been chosen, click OK.
7. You can return to the Layer List at any time to make adjustments (showing or hiding layers, changing "show" to "range" or vice versa, etc.)
