Remarks
geoDataset |
an input Raster, RasterDataset, RasterBand, or RasterDescriptor representing a continuous surface |
profile |
a Boolean that if True will create an output profile Raster The profile Raster shows the rate of change of slope for each cell. This is the curvature of the surface in the direction of slope. |
plan |
The plan Raster shows the curvature of the surface perpendicular to the slope direction, referred to as the planform curvature. |
[zFactor] |
The number of ground x, y Units in one surface ZUnit The geoDataset ZUnits are multiplied by the specified zFactor to adjust the output Raster ZUnits to another unit of measure. If no zFactor is specified the value of the zFactor is 1. Higher z values will result in a more exaggerated relief (surface) and thus in a more extreme shading. |
- The method returns a reference to a Raster object.
