Class AspectFunction

java.lang.Object
  com.esri.arcgis.datasourcesraster.AspectFunction

All Implemented Interfaces:

IRasterFunction, com.esri.arcgis.interop.RemoteObjRef, IPersist, IPersistStream, IXMLSerialize, IXMLVersionSupport, Externalizable, Serializable

public class AspectFunction
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IRasterFunction, IPersist, IPersistStream, IXMLSerialize, IXMLVersionSupport, Externalizable

The Aspect function.

Description

Calculates the Aspect values for an elevation model. Aspect values identify the downslope direction of the maximum rate of change in value from each cell to its neighbors. Aspect can be thought of as the slope direction. The values of the output raster will be the compass direction of the aspect.
