GIS UNM CE547 Spring 2006

Assignment 4

In the first frame, we import an interchange file of a Digital Elevation Model of the Albuquerque area. Using the arcgis "flowdirection", "flowaccumulation", and "streamlink" GRID functions, we construct a stream network. The elevation is keyed in false color.

In the second frame, we have zoomed in on a region of the East Mountains. Using the "zonalmax", "con", and "watershed" functions, we dispay unique watersheds overlain with previously calculated stream network.
