what is a topographic map??

Question

i need to know!

Answer 1

A map that represents the elevation of the earth.

Answer 2

A map is a representation of the Earth, or part of it. The distinctive characteristic of a topographic map is that the shape of the Earth's surface is shown by contour lines. Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface, such as mean sea level. Contours make it possible to measure the height of mountains, depths of the ocean bottom, and steepness of slopes.

A topographic map shows more than contours. The map includes symbols that represent such features as streets, buildings, streams, and vegetation. These symbols are constantly refined to better relate to the features they represent, improve the appearance or readability of the map, or reduce production cost.

Consequently, within the same series, maps may have slightly different symbols for the same feature. Examples of symbols that have changed include built-up areas, roads, intermittent drainage, and some lettering styles. On one type of large-scale topographic map, called provisional, some symbols and lettering are handdrawn.

Answer 3

A map that shows the various altitudes of the mapped area, usually by drawing lines that are at equal altitude so they look like loops around a hill. A map could be molded to show height but it would be awkward to carry (and fold). Allows a person to gauge the difficulty of walking through the area or an engineer to figure the best line for a road, etc.

Answer 4

A topographic map not only maps things like where lakes and cities are but shows the altitude of things. A hill may have a bunch of circles (with a legend that marks the height with numbers ) or colors that differentite the altitude. It just tells you how high things are.
