  2. Heightmap - Wikipedia

    en.wikipedia.org/wiki/Heightmap

    This technique is especially useful where height varies slightly over a large area. Using only grey values, because the heights must be mapped to only 256 values, the rendered terrain appears flat, with "steps" in certain places. Height map of planet earth at 2km per pixel, including oceanic bathymetry information, normalized as 8-bit grayscale

  3. Roblox - Wikipedia

    en.wikipedia.org/wiki/ROBLOX

    Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [45] Roblox operates annual Easter egg hunts [51] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...

  4. Diamond-square algorithm - Wikipedia

    en.wikipedia.org/wiki/Diamond-square_algorithm

    Each random value is multiplied by a scale constant, which decreases with each iteration by a factor of 2 −h, where h is a value between 0.0 and 1.0 (lower values produce rougher terrain). [ 2 ] During the square steps, points located on the edges of the array will have only three adjacent values set, rather than four.

  5. DTED - Wikipedia

    en.wikipedia.org/wiki/DTED

    DTED supports many applications, including line-of-sight analyses, terrain profiling, 3-D terrain visualization, mission planning/rehearsal, and modeling and simulation. DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications ...

  6. Elevation - Wikipedia

    en.wikipedia.org/wiki/Elevation

    A topographical map is the main type of map used to depict elevation, often through contour lines. In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain ...

    en.wikipedia.org/wiki/Wikipedia:WikiProject_Maps/...

    Topographic maps, displaying an area's relief, de facto explain many other things such as human occupation, cultivated areas, kingdoms borders, exchanges ways, etc. If you create a topographic map, note that these colorimetric values are indicatives.

  8. Cities XL - Wikipedia

    en.wikipedia.org/wiki/Cities_XL

    The terrain is composed of height maps, textures and a normal map. Instead of creating new tools, Monte Cristo relies on existing third-party tools like EarthSculptor , World Machine and GeoControl to generate unique realistic terrain before importing it into their terrain-editing software.

  9. 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 ...
