Topographic Map With Contour Lines

Topographic maps do not show every contour line rather they choose sample of the lines. Current generation topographic maps are created from digital gis databases and are branded us topo. Contour lines show elevation and the shape of the terrain.

What Are Contour Lines How To Read A Topographical Map 101

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.

Topographic map with contour lines. Topographic maps use a combination of colors shading and contour lines to represent changes in elevation and terrain shape. In modern mapping a topographic map or topographic chart is a type of map characterized by large scale detail and quantitative representation of relief usually using contour lines connecting points of equal elevation but historically using a variety of methods. When you have a closed contour like the one below this means there is a hill mountain or depression. For a quick definition a contour line joins points of equal and constant values.

Essentially topographic maps represent the three dimensional landscape of earth within the two dimensional space of a map. The main characteristic of such maps is the representation of the three dimensional terrain or relief of the surface of the earth by the use of contour lines. For example contours on an elevation have constant heights that are the same on each line. Topographic maps topo maps and contour lines topographic maps provide a detailed represention of the natural and man made features of the earth s surface.

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. For example every 20 50 200 metres depending on the scale of the map. Contour lines are the primary and most important feature on a topo map.

Are these contour lines mountains or depressions. Think of contour lines as imaginary horizontal planes sliced through the terrain surface. This is called the contour interval of the map. A word of warning.

Co ntour li nes are the greatest distinguishing feature of a topographic map. Topographic maps these are general use maps at medium scales that present elevation contour lines hydrography geographic place names and a variety of cultural features. A map with contour lines on it is called a topographic map.
