A raised-relief map, terrain model or embossed map is a three-dimensional representation, usually of terrain, materialized as a physical artifact. When representing terrain, the vertical dimension is usually exaggerated by a factor between five and ten; this facilitates the visual recognition of terrain features.
An illustration of the resolution bumping technique of shaded relief, Bitterroot Mountains and Salmon River, Montana/Idaho. Left: 200 m resolution shaded relief, middle: shaded relief after 7000 m smoothing filter, right: 65%/35% mix. The original image looks uniformly rugged, while the one on the right emphasizes the larger mountains and canyons.
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.
Shaded relief map of the United States, showing 10 geological provinces. The richly textured landscape of the United States is a product of the dueling forces of plate tectonics, weathering and erosion. Over the 4.5 billion-year history of the Earth, tectonic upheavals and colliding plates have raised great mountain ranges while the forces of ...

Several methods have been developed for visualizing elevation and the shape of the Earth's surface. Some techniques date back hundreds or thousands of years and are difficult to replicate digitally, such hill profiles and hachures; others, such as shaded relief and contour lines, are much easier to produce in GIS than using manual tools. Some ...
Relief map or mapping may refer to: Raised-relief map, a 3D physical representation of terrain; Relief mapping (computer graphics), the 3D digital rendering of ...
A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) (from Scale (map)) Image 32 Universalis Cosmographia , the Waldseemüller wall map dated 1507, depicts the Americas, Africa, Europe, Asia, and the Pacific Ocean separating Asia from ...
