A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system.
A map symbol or cartographic symbol is a graphical device used to visually represent a real-world feature on a map, working in the same fashion as other forms of symbols. Map symbols may include point markers, lines, regions, continuous fields, or text; these can be designed visually in their shape, size, color, pattern, and other graphic ...
Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. [1] In the United States, topography often means specifically relief, even though the USGS topographic maps record ...
NATO Joint Military Symbology is the NATO standard for military map symbols. Originally published in 1986 as Allied Procedural Publication 6 (APP-6), NATO Military Symbols for Land Based Systems, the standard has evolved over the years and is currently in its fifth version (APP-6D). The symbols are designed to enhance NATO 's joint ...
An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the coordinates provided. (In some cases, squares adjacent to a Grid Zone Junction (GZJ) are clipped, so polygon is a better ...
The National Topographic System or NTS is the system used by Natural Resources Canada for providing general purpose topographic maps of the country. NTS maps are available in a variety of scales, the standard being 1:50,000 and 1:250,000 scales. [1] The maps provide details on landforms and terrain, lakes and rivers, forested areas ...
In the future, a good way to follow should be to start a methodical project, based on the German Location map initiative, working continent after continent and country after country, to provide a complete set of SVG topographic maps, respecting these topographic conventions. To learn. Several tutorials are now available, on wiki-en, wiki-fr ...
A " quadrangle " is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand " quad " is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". A quadrangle is defined by north and south ...
