This Knowledge Base article is an excerpt from one of our tutorial files. The files referenced in the article, as well as the full tutorial document, are available in our Tutorial Installer.  
  1. File | Open <Terrain>\Import\roads_a.terx.

Figure 1: roads_a.terx Before the Projection is Defined.

Notice that the Status window displays coordinates (Easting and Northing) but Latitude and Longitude are undefined (figure above).

roads_a.terx does not have any coordinate information attached to it but it is known to be in UTM Zone 11 NAD 83 coordinates. If we setup the coordinate system in Terrain, the file will be geo-referenced.

  1. Define the UTM projection: Setup | Module Setup Button | Projection tab.

  2. Change the Projection settings to those shown in the figure below. Press OK.

Figure ‑: Projection Settings

Notice that the Status window now displays Latitude and Longitude.
