Terrain Features On A Topographic Map

Landform refers to the shape of the land and is a function of elevation and relief that is the representation as depicted by the mapmaker of the shapes of hills valleys streams or terrain features on the earths surface. The topographic map is a two-dimensional representation of the Earths three-dimensional landscape. Heres a quick and dirty illustration. The defining feature of a two-dimensional topographical map is its contour lines.

Similar maps at varying scales were produced during the same time period for Alaska Hawaii and US Territories.

Terrain Features On A Topographic Map. Contour lines are also a common way for showing differences in elevation and terrain although color can play a major part as well. A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads railways power transmission lines contours elevations rivers lakes and geographical names. A hill peak knoll or mountain is an area of high ground.

An easy way to imagine a contour line is. One reason for this classification system is basically due to the sheer size of the terrain features because the major terrain features are on a larger scale than the minor or supplementary ones are. Traditional definitions require a topographic map to show both natural and artificial features.

So imagine this as a hill that from the bottom left of the diagram proceeding up gains elevation. 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. Both elevation and relief allow users to recognise landforms.

A contour line is a line joining points of equal elevation on a surface. You must be able to recognize all the terrain features to locate a point on the ground or to navigate from one point to another. Major terrain features include hills saddles gullies ridges and depressions and they each have characteristic contour lines that make it easy to pick them out in the landscape.
