Global Mapper

Version 4.74 of Global Mapper added advanced blending capabilities to the rendering of raster data. The program can apply a variety of Photoshop® style blends (i.e. Hard Light, Multiple, Screen, Difference, etc.) to loaded elevation and raster data.

In this example, a 30-meter DEM and a grayscale orthophoto were opened in Global Mapper. In the Control Center, the orthophoto was texture mapped to the underlying elevation model using the "Difference" blend option. The DEM was set to the Atlas Shader color scheme. Paint Shop Pro was used to adjust contrast and saturation and to add labels. The map site is located in Wisconsin's Baraboo Bluffs.
