A map with contour lines on it is called a topographic map.

What do contour lines represent on a topographic map

. The lines themselves represent elevation and as other posters point out the distance between them shows gradient or the slope of the land. Essentially topographic maps represent the three dimensional landscape of earth within the two dimensional space of a map. Contour lines represent the shape and elevation of the land such as ridges valleys and hills. Co ntour li nes are the greatest distinguishing feature of a topographic map.

Regional maps need only show broad contours and 100 is typical otherwise the density of the image would render them unreadable while site plans for construction proposals may even get down to 1 2 gradients to simplify. Lighter contour lines do not have elevations but can be determined by counting up or down from the nearest index contour line and multiplying by the contour interval. Types of contour lines. Common topographic map symbols.

A topographic map is printed on a flat piece of paper yet it provides a picture of the terrain and manmade features through the use of contour lines colors and symbols. Most maps i use the distance between the contour lines represents 10 meters. Colors and symbols are used to represent other features on the land such as water vegetation roads boundaries urban areas and. Contour lines are wavy circular lines employed on a two dimensional topographic map that depict elevation on the ground.

Contour lines show levels. Contour lines are lines drawn on a map connecting points of equal elevation meaning if you physically followed a contour line elevation would remain constant. How to read a topographic map. A contour map is a map illustrated with contour lines for example a topographic map which thus shows valleys and hills and the steepness or gentleness of slopes.

To communicate the precision of the vertical measurement. The contour interval is stated on every topographic map and is usually. The distance between each contour line is set to represent a certain level of elevation with zero being sea level. The map legend should specify the gradient whether 10 50 etc.

In cartography a contour line often just called a contour joins points of equal elevation height above a given level such as mean sea level. Contour lines show elevation and the shape of the terrain. Topographic maps use a combination of colors shading and contour lines to represent changes in elevation and terrain shape. On most topographic maps index contour lines are generally darker and are marked with their elevations.

On most topographic maps index contour lines are generally darker and are marked with their elevations. Topographic maps use a combination of colors shading and contour lines to represent changes in elevation and terrain shape. Contour lines show elevation and the shape of the terrain.
