They are represented on two-dimensional maps as they are seen from the air, or in aerial photography. [1] These features are often digitized from orthorectified aerial photography into data layers that can be used in analysis and cartographic outputs. [2] A planimetric map is one that does not include relief data. [3]
The two straight-line distances from any point on the map to the two control points are correct. 2021 Gott, Goldberg and Vanderbei’s Azimuthal Equidistant J. Richard Gott, Dave Goldberg and Robert J. Vanderbei: Gott, Goldberg and Vanderbei’s double-sided disk map was designed to minimize all six types of map distortions.
The various features shown on the map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. These signs are usually explained in the margin of the map, or on a separately published characteristic sheet. [17] [18] [19] Topographic maps are also commonly called contour maps or ...

A map of Europe using elevation modeling. In its contemporary definition, topographic mapping shows relief. In the United States, USGS topographic maps show relief using contour lines. The USGS calls maps based on topographic surveys, but without contours, "planimetric maps."
There are several kinds of planimeters, but all operate in a similar way. The precise way in which they are constructed varies, with the main types of mechanical planimeter being polar, linear, and Prytz or "hatchet" planimeters.
An intense blast of cold air has taken up shop in the central United States this week with temperatures up to 50 degrees below average and over 200 daily cold records at risk of being broken.
