Contour Line Topography Mapping Surveying Britannica

Contour Line Topography Mapping Surveying Britannica Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. contour line a topographic map with contour lines connecting places that are the same height above sea level. numbers on the lines give the height in feet. (sea level is zero.). Accessed 11 september 2024. contour mapping, the delineation of any property in map form by constructing lines of equal values of that property from available data points. a topographic map, for example, reveals the relief of an area by means of contour lines that represent elevation values; each such line passes through.

Contour Line Topography Mapping Surveying Britannica Topographic map. topographic map, cartographic representation of the earth’s surface at a level of detail or scale intermediate between that of a plan (small area) and a chorographic (large regional) map. within the limits of scale, it shows as accurately as possible the location and shape of both natural and man made features. A land survey measures the horizontal positions and elevations and is used to establish reference marks to guide construction or to indicate property lines. in a topographic survey, altitudes are measured very precisely in order to describe the relief of mountains, valleys, and plains for topographic maps—scale drawings of a part of the earth. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. [3] 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]. Topographic mapping and the usgs. a longstanding goal of the usgs has been to provide complete, large scale topographic map coverage of the united states. the result is a series of more than 54,000 maps that cover in detail the entire area of the 48 contiguous states and hawaii. produced at a scale of 1:24,000 (some metric maps are produced at.

This is a close up of a 1:100,000 scale topographic map (100k topo) of the arizona national scenic trail (az nst) from the kaibab plateau at top to the grand canyon north rim at bottom. the az nst is highlighted in red. this map shows contour lines, hydrography, landform names, land cover, federal lands, roads, and structures.
