Height above mean sea level. Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and ...

The National Geodetic Vertical Datum of 1929 is the official name since 1973 [1] of the vertical datum established for vertical control surveying in the United States of America by the General Adjustment of 1929. Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the United States Coast and Geodetic Survey [2 ...
Elevation. The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term elevation is mainly used when referring to points on the Earth's ...
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial ...
Driskill Mountain. Driskill Mountain (also referred to as Mount Driskill) is the highest natural summit in Louisiana, with an elevation of 535 feet (163 m) above sea level. [3] It lies about 5.3 miles (8.5 km) southeast of Bryceland, in Bienville Parish. A large pile of rocks marks the high point.
