You can add as many types of map layers as you need. CWMS 3.3.0 can transform coordinates "on-the-fly" as long as a map layer's coordinate system is properly defined. You can add map layers to any of the modules from the Maps menu. When you add a map layer to the watershed, the CWMS software reads the coordinates of points, lines, and polygons on the map layer and resets the geographic extents of your watershed to the smallest rectangle that will contain all objects in the map layer. 

To add map layers:

  1. From the CWMS CAVI main window, under the Maps menu click Map Layers. The Map Layers editor will open.
    Map Layers Editor
  2. From the Layers menu, click Add Maps. The Select Map to Add browser will open.
    Select Map to Add Browser
  3. Select the desired map layer format from the Files of type dropdown list. Select the filename and click Open. The Select Map to Add browser will close. The selected map layer will display in the map window and will display under the Map Layers tree.

When enabled, the Create Copy checkbox (default) on the Select Map to Add browser will copy the selected map layer to the active watershed's directory structure under the maps folder.
