To maximize readability of contour maps, there are several design choices available to the map creator, principally line weight, line color, line type and method of numerical marking. Line weight is simply the darkness or thickness of the line used. This choice is made based upon the least intrusive form of contours that enable the reader to ...
Topographic maps are also commonly called contour maps or topo maps. In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines.
This page provide conventions to produce topographic maps. Topographic maps, displaying an area's relief, de facto explain many other things such as human occupation, cultivated areas, kingdoms borders, exchanges ways, etc. If you create a topographic map, note that these colorimetric values are indicatives.
DOT.MAP - contour, shaded, and dot-distribution maps from gridded data; KWIC - key-word-in-context programs for indexing bibliographic references; POLYVRT - data conversion and analysis of polygonal data; SYMAP - line printer mapping producing conformant (areas), contour, trend surface, and proximal (also known as Voronoi diagram or Thiessan ...
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.

Siegfried map of Bernina Pass (1877) with black, blue and brown contour lines at 30-meter intervals. On maps produced by Swisstopo, the color of the contour lines is used to indicate the type of ground: black for bare rock and scree, blue for ice and underwater contours, and brown for earth-covered ground.

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]
