FAMILIARIZED TOOLS FROM ARCGIS

Filling - conditioning of the raster DEM or

filling of sinks in a raster to remove small

imperfections.

Flow direction- a process to create a raster flow

direction from each cell to its steepest "'0#s%',e

#e)(!1'.

Flow accumulation- a process to create a

raster of accumulated flow to each cell

31

25


32/57

Watershed Pour Points: In Arc Catalog we will create a

new empty shape file to store the new pour point.

watershed : In this final step we select the flow direction

grid as the input flow direction raster and the raster

version of the pour point as the input pour point data.

!inally we select an output raster pathname. "he new

watershed raster will #e added to the map.
