ChromaDepth

TNTmips has many ways of presenting 3D geo data, including support for several hardware devices. Of these, ChromaDepth images are perhaps the most vivid and easy to create. 3D data is encoded into the image hues, with blues assigned to elements farthest into the image and red for those closest to the viewer. A simple pair of glasses make the third dimension visible. The glasses can be ordered from ChromaTek for a reasonable price.

How do you make these images with TNTmips?

First you need a DEM and a grayscale image corresponding to the same geographic area. (You may need to resample the rasters to the same row/column size).
Color map your DEM (in the TNT Display process) using the standard chromadepth color pallete.
Use Process/Raster/Combine/Color Convert to split the DEM into 3 bands, using the RGB option to allow for easier adjustments using contrast enhancements.
Finally, use the RGBI display option with I being the grayscale image.

View the results with a pair of ChromaTek's, ChromoDepth 3D glasses.
