Class STTopography
Extends STTransformRaster
Allow for the creation of slope, aspect, hillshade, and other topographic raster
layers from a DEM.
For information on how to create a hillshade see:

Static Functions
STRaster Aspect(STRaster TheInput,double ZFactor) Exception
Creates an raster from the input DEM raster
Parameters:
TheInputRaster - The DEM to use as the starting raster
ZFactor - The cells size of the final raster in the horizonal
STRaster AspectEastWest(STRaster TheInput,double ZFactor) Exception
Creates an aspect raster from a DEM where each pixel represents
how much a pixel's slope faces north vs. south.
Parameters:
TheInputRaster - The DEM to use as the starting raster
ZFactor - The cells size of the final raster in the horizonal
STRaster Hillshade(STRaster TheInputRaster,double Elevation,
double Direction,double ZFactor,STColorRamp TheColorRamp)
Exception
Creates a colorized or grayscale hillshade from a DEM. This
function works by creating a grayscale hillshade and then
multiplying it by a colorized raster to create a hillshade in
a single function.
Parameters:
TheInputRaster - The DEM to use as the starting raster
Elevation - The elevation of the sun above the horizon given as
STRaster Slope(STRaster TheInput,double ZFactor) Exception
Creates a slope raster from the input DEM raster
Parameters:
TheInputRaster - The DEM to use as the starting raster
ZFactor - Factor to expand the hillshade vertically. This also
