US Topographic map shows the locations and forms of hills, valleys, streams, and others features as well as many man-made landmarks. They illustrate the shape and elevation of surfaces features by the use of contour lines. A type of map characterized by large-scale detail and quantitative representation of relief features using contour lines.

How is a topographic map made?
U.S. Topographic maps were made using data from primary sources including direct field observations. Those US maps of Topographic were compiled, drawn, and edited clearly by hand. By today’s standard, these traditional methods are very expensive and time-consuming and the USGS has no longer fundings for this to make maps that way.
Topographic map – Characteristics & Purposes
The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the earth’s surface. Elevation contour lines are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which usually means sea level.

Topographic map of USA – Types & Features
There are three types of topographic maps:
1: Karst topography- describes the distinct landscape that is made when underlying rocks dissolve or change shape.
2: Mountain topography- shows landforms such as hills and mountains.
3: Vegetation, elevation, and Glaciers

Importance of topographic map : In agriculture, it determines the method of soil conservation and the flow of water. It helps in minimizing soil erosion by helping scientists in giving information on the landmass. Weather forecasting also gets benefits from it. Military uses this to gather information on the land area. They could plan their strategies with this map. Civil engineers and various government officers use it to perform their activities in an effective manner.
