Flow accumulation grid generated from 10 meter DEM, Andrews Experimental Forest. This grid is useful for determining the area of land that drains to a point. The user selects a point on the grid, and the value of that point represents the area (in 100 square meters) that drain to the point. This grid can also be used for generating watershed boundaries and stream networks.

FSL Metadata
cell value is the calculated number of 10x10 meter cells that drain to the cell location. This is useful in determining the landscape area that drains to each point in the grid.

value represents the amount of area that flows to the pixel (multipy by 100 square meters).
generated from 10 meter DEM
generated from 10 meter DEM
USGS DEM was converted to lattice. 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
