3.5.2.1 Inserting an Alternative Network Topology Map
With CTC you can install a custom map for the network view. The map needs to be in either a JPEG
or GIF file format and stored on an accessible local or network drive. Approximate longitudes and
latitudes for the edge coordinates of the map are required — this information is included on U.S.G.S.
topographical maps, and you can obtain the longitude and latitude for cities and Zip Codes from the
U.S. Census Bureau U.S. Gazetteer website (http://www.census.gov/cgi-bin/gazetteer). CTC uses
the edge coordinates of the custom map to determine the relative positions of the ONS node icons
on the map graphic. Edge coordinates only need to be precise enough to place ONS node icons in
approximate positions on the map graphic.
Procedure: Set Up an Alternative Network Map
Step 1 From the menu bar in network view, choose Edit > Preferences or click the Preferences
tool in the toolbar.
The Preference dialog box appears (Figure 3-8) with the four tabs listed in Table 3-5.
