METHODS:

Processing Procedures - HF016:

Description: HF0160:USGS DEM was converted to lattice. Data processes were done for the entire Willamette Basin. Sinks were filled, flow direction grid was created, and flow accumulation grid was created and clipped to Andrews Experimental Forest boundary. Metadata was created in 2005. GRID functions used: sink, flowdirection, flowaccumulation. Data was projected from NAD27 to NAD83 to meet US Forest Service requirements.
