What Is A Topographic Profile Map

What is a topographic profile map

Topographic maps are based on topographical surveys. A contour line is a type of isoline. It provides a side view of the relief of the terrain along a line drawn between two locations on a topographic map.

Constructing A Topographic Profile

A topographic map is a map that indicates the features of the land s surface such as mountains hills and valleys.

An elevation profile or a topographic profile is a two dimensional cross sectional view of the landscape. A topographic profile is a cross sectional view along a line drawn through a portion of a topographic map. Topographic profiles are used to understand what a topographic map is telling you in a specific area or you can think about it like it is giving you a side view of the landscape along a specific line on the map.

Topographic maps represent the locations of geographical features such as hills and valleys. The great trigonometric survey of india started by the east. Each contour line can be defined as a closed line joining relief points at equal height above sea level.

A topographic profile is a side cross sectional view along a line drawn on a topographical map.

Topographic is the adjective form of the noun topography which refers to the surface features of land.
If you walk along a contour line you will not go uphill or downhill.
In other words if you could slice through a portion of the earth pull away one half and look at it from the side the surface would be a topographic profile.
A very useful exercise for understanding what topographic maps represent is the construction of a topographic profile.

By plotting elevation versus horizontal distance one.

Not only does constructing a topographic profile aid in understanding. In this case a line of equal elevation. Interestingly many geologists are quite visual and like to have visual representations of data.

A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map.

This is in contrast to older cadastral surveys which primarily show property and governmental boundaries the first multi sheet topographic map series of an entire country the carte géométrique de la france was completed in 1789.
Topographic maps use contour lines to show different elevations on a map.
This is typically done with wavy lines that represent the curves and elevation of the land.
Performed at large scales these surveys are called topographical in the old sense of topography showing a variety of elevations and landforms.
