  2. Topographic map - Wikipedia

    en.wikipedia.org/wiki/Topographic_map

    A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. 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 ...

    en.wikipedia.org/wiki/Glossary_of_geography_terms...

    This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...

  4. Topography - Wikipedia

    en.wikipedia.org/wiki/Topography

    Digital Elevation Models, for example, have often been created not from new remote sensing data but from existing paper topographic maps. Many government and private publishers use the artwork (especially the contour lines) from existing topographic map sheets as the basis for their own specialized or updated topographic maps. [9] Topographic ...

  5. Topographic profile - Wikipedia

    en.wikipedia.org/wiki/Topographic_profile

    Example of topographic profile. A topographic profile or topographic cut or elevation profile is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level. [1]

  6. Draw (terrain) - Wikipedia

    en.wikipedia.org/wiki/Draw_(terrain)

    Example on a topographical map, and how it would look in the real world. Typical draw, Little Carpathians. A draw, sometimes known as a re-entrant in orienteering, is a terrain feature formed by two parallel ridges or spurs with low ground in between them. The area of low ground itself is the draw, and it is defined by the spurs surrounding it.

  7. Terrain cartography - Wikipedia

    en.wikipedia.org/wiki/Terrain_cartography

    USGS topographic map of Stowe, Vermont with contour lines at 20-foot intervals. 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.

  8. 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/.../Conventions/Topographic_maps

    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 ...
