A topographic map shows. Topographic maps a topographic map is similar to a physical map in that it shows different physical landscape features. The map includes symbols that represent such fea tures as streets buildings streams and vegetation. Topographic maps a topographic map is a type of map that shows heights that you can measure. The more populated areas of alaska.

A traditional topographic map will have all the same elements as a non topographical map such as. A contour lineis a type of isoline. A topographic map shows more than contours.

Contour lines are the primary and most important feature on a topo map. Geological survey topographic maps usu ally represent elevations and landforms the shapes into which the earth s surface is sculp tured by natural forces by contour lines. Puerto rico for example maps at 1 20 000 or 1 30 000 because the country originally mapped at a metric scale. You ll find most of the united states mapped at the 1 24 000 scale with only a few exceptions.

For usgs topographic maps 1 24 000 is the scale most often used. Topographic maps use contour lines to show different elevations on a map. Traditional definitions require a topographic map to show both natural and man made features. A topographic survey is typically based upon systematic observation and published as a map series made up of two or more map sheets that combine to form the whole map.

Think of contour lines as imaginary horizontal planes sliced through the terrain surface. Topographic mapsrepresent the locations of geographical features such as hills and valleys. Older maps published before 2006 show additional features such as trails buildings towns mountain elevations and survey control points. Unlike physical maps though this type of map uses contour lines instead of colors to show changes in the landscape.

They show the shape of the terrain including its hills slopes and depressions by tracing a constant line of elevation on the map that corresponds with the landscape in the real world. Maps based on metric units use a scale of 1 25 000 where one centimeter equals 0 25 kilometers. Usgs topographic maps also show many other kinds of geographic features including roads railroads rivers streams lakes boundaries place or feature names mountains and much more. In this case a line of equal elevation.

These symbols are con stantly refi ned to better relate to the features they represent improve the appearance or readability of the map or reduce production cost. They show elevation using contour lines. Characteristics of topographic maps include.
