Total Magnetic Intensity (TMI) gridded data from geophysical surveys.The most common type of input is a DEM however, you can also use the following: The Topographic Shading Tool accepts any single-band raster as input. You can also write a script to perform topographic shading using one of the following tasks: TopographicShadingUsingHLS, TopographicShadingUsingHSV, or TopographicShadingUsingRGB. The resulting image can be used for visualization and presentation. Then you can save the result to an ENVI-format image with the same spatial resolution as the input DEM. You can preview the resulting image as you adjust settings for the DEM, topographic features, and the level of blending. A common use is to blend a colored DEM with a shaded relief image to produce a hillshade image that emphasizes terrain relief. The result is an image that provides a better visual representation of the shape and texture of topographic features than using the DEM alone.
Examples of topographic features include shaded relief, slope, aspect, and derivatives of slope and aspect.
Use the Topographic Shading Tool to blend a color representation of a digital elevation model (DEM) with a topographic feature.
