Database of Geographic Information: Aspect 30_utm

This dataset has been created to meet the needs of the research community of Arizona State University. Aspect can be thought of as the slope direction. It identifies the down-slope direction of the maximum rate of change in value (elevation) from each DEM cell to its neighbor cells. The values of the output grid are the compass direction of the aspect. The data is derived from the 30 meter Digital Elevation Model created for Central Arizona - Phoenix LTER (dem30_utm).
