  2. Topographic profile - Wikipedia

    en.wikipedia.org/wiki/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 ]

  3. 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 ...

    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.

  5. Contour line - Wikipedia

    en.wikipedia.org/wiki/Contour_line

    A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. [4] The contour interval of a contour map is the difference in elevation between successive contour lines. [5] The gradient of the function is always perpendicular to the contour ...

Most of time, these upper layers are transport ways (see exchanges maps), Kingdoms' areas or troops and moves (see areas maps & historical maps), or even officials borders from location maps.

  8. Watershed delineation - Wikipedia

    en.wikipedia.org/wiki/Watershed_delineation

    For "manual" watershed delination, one must know how to read and interpret a topographic map, for example to identify ridges, valleys, and the direction of steepest slope. [3] Even in the computer era, manual watershed delineation is still a useful skill, in order to check whether watersheds generated with software are correct. [1]

  9. Category:Topography - Wikipedia

    en.wikipedia.org/wiki/Category:Topography

    This category refers to topography, a general term in geography.Although it can be used to describe the study of place or large-scale phenomena, it is more widely used to describe the general study and graphic representation of landforms, the three-dimensional aspect of the Earth's (or other planets') surface.
