Summary[edit]

Description
English: Today for #tbt we find a USGS topographer running a level line in the Alabama Hills near Mt. Whitney, California. The picture was taken in 1984.

Leveling is a surveying operation in which heights of objects and points are determined relative to a specified datum.

In order for USGS maps to be an accurate representation of the real world, cartographers must know the position (latitude, longitude and height) of a selection of features that can be found on the map.
