  2. Raised-relief map - Wikipedia

    en.wikipedia.org/wiki/Raised-relief_map

    In order to create a raised-relief map using a 3D printer, Digital Elevation Models (DEM) are rendered into a 3D computer model, which can then be sent to a 3D printer. Most consumer-level 3D printers extrude plastic layer by layer to create a 3D object. However, if a map is needed for commercial and professional uses, higher-end printers can ...

  3. Terrain cartography - Wikipedia

    en.wikipedia.org/wiki/Terrain_cartography

    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 ...

  4. Relief map - Wikipedia

    en.wikipedia.org/wiki/Relief_map

    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 texture, which may simulate shadows; Topographic map, a 2D depiction of terrestrial relief, using terrain cartography

  5. Digital elevation model - Wikipedia

    en.wikipedia.org/wiki/Digital_elevation_model

    Creation of relief maps; Rendering of 3D visualizations. 3D flight planning and TERCOM; Creation of physical models (including raised relief maps and 3D printed terrain models) [28] Rectification of aerial photography or satellite imagery; Reduction (terrain correction) of gravity measurements (gravimetry, physical geodesy)

  6. National Elevation Dataset - Wikipedia

    en.wikipedia.org/wiki/National_Elevation_Dataset

    The NED dataset is a compilation of data from a variety of existing high-precision datasets such as LiDAR data (see also National LIDAR Dataset - USA), contour maps, USGS DEM collection, SRTM and other sources which were reorganized and combined into a seamless dataset, designed to cover all the United States territory in its continuity.

  7. Global relief model - Wikipedia

    en.wikipedia.org/wiki/Global_Relief_Model

    A global relief model, sometimes also denoted as global topography model or composite model, combines digital elevation model (DEM) data over land with digital bathymetry model (DBM) data over water-covered areas (oceans, lakes) to describe Earth's relief. A relief model thus shows how Earth's surface would look like in the absence of water or ...

  8. TopoQuest - Wikipedia

    en.wikipedia.org/wiki/TopoQuest

    In addition to matching the Topozone URL's, the website offers free download of GeoTIFFs, which Topozone had only offered for a premium. TopoQuest started adding Canadian 1:50K scale topographic maps in July 2008, and USGS 1:100K and 1:250K scale topographic maps in March 2009.

  9. Terrain - Wikipedia

    en.wikipedia.org/wiki/Terrain

    Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution.
