What Does Topographic Map Mean

A topographic map can be easy to read once you know the details. Maps come in a variety of scales, covering areas ranging from the entire earth to a city block (or less). A topographic map or topographic sheet, in modern mapping, is a form of the map associated with large detail and quantitative representation of relief, typically employing contour lines (connecting points of equal elevation), but traditionally using a range of techniques.

A topographic map uses symbols to keep the map less crowded, but it's. The topography is represented by contour lines, which are imaginary lines. Topographic maps are detailed, accurate graphic representations of features that appear on the earth's surface.

These lines are generally relative to mean sea level.

For example, individual houses may be shown as small black squares. Geological survey reading topographic maps interpreting the colored lines, areas, and other symbols is the fi rst step in using topographic maps. A map is a diagrammatic representation of the actual features of the earth. The meaning of topographic map is a map intermediate between a general map and a plan on a scale large enough to show roads, plans of towns, and contour lines.
