This tutorial will introduce you to using ArcView to produce custom map background files and then demonstrates how to move and install these files on your Advanced Weather Information Processing System.
All shapefile objects consist of either a point, a line, or a polygon.
For instance, the WSR-88D radar sites are stored as points. Highways are stored as lines, and CWAs are stored as polygons. The actual shape file that holds the data is 252Kb. Once you have the file available on the PC go ahead and start up ArcView. Note, that in the case of the interstate highways, this file already came with the ArcView 3.1 installation and is called roads.shp and can be found in the Esridata-USA directory where your other ArcView files are located.
