In computer graphics, relief mapping is a texture mapping technique first introduced in 2000 [1] used to render the surface details of three-dimensional objects accurately and efficiently. [2] It can produce accurate depictions of self-occlusion, self-shadowing, and parallax. [3] It is a form of short-distance ray tracing done in a pixel shader.
Export the maps 5. Export the first shaded relief map in PNG format: File-> Export raster map-> PNG. In the r.out.png module window, select the file Shadows_315. In the field Name for new PNG file:, replace <rasterfilename> with Shadows_315, then click on the Run button. The file is saved by default in the C:\GRASS directory. 6.

To proceed with this tutorial you need GDAL and ImageMagick, if you want to add rivers and lakes you need also some Natural Earth files. This tutorial is written to be used on Posix systems (Linux, BSD, Mac OS X, Windows Cygwin), but with minor changes of command line commands it can be used under Windows itself.
Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography , and as such its portrayal presents a central problem in cartographic design , and more recently geographic ...
