III. b. Organize Data Layers
             Estimated time:
             2 minutes
A major advantage of using ArcMap to delineate a watershed is the use of multiple layers to determine the flow direction of surface water runoff. We need to turn some layers off and reorder them to get a better view of the topography.
In this exercise, you will:
  • Isolate desired data layers.
  • Organize the data layers.

    1. Turn off all layers except “Contours”, “Pour Point”, “Rivers and Streams”, “Water Bodies”, “Delineate Watershed”, “DEM”

    2. Place them in that order from top to bottom
