This provides a method to calculate the roughness length by measuring the friction velocity and the mean wind velocity (at known elevation) in a given, relatively flat location (under neutral conditions) using an anemometer. [4] Of note is that, in this simplified form, the log wind profile is identical in form to the dimensional law of the wall.
In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height.

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 historic measurement periods.
Elevations Credit Union is a not-for-profit credit union with over $3 billion in assets and more than 170,000 members. [1] [2] The credit union serves Adams, Arapahoe, Boulder, Broomfield, Clear Creek, Delta, Denver, Douglas, Eagle, El Paso, Gilpin, Grand, Jefferson, Larimer, Mesa, Park, Summit and Weld counties.
The acronym TVDSS is commonly used in the oil industry to represent TVD minus the elevation above mean sea level of the depth reference point of the well. The depth reference point is the kelly bushing in the United States and a few other nations, but is the drill floor in most places.
The summit, at 5,075 feet (1,547 m) in elevation, is the highest point within the city limits. [5] The summit's elevation makes Los Angeles the city with the largest difference between high and low points among the 50 most populous cities in the US.
Homestake Pass is a mountain pass in the Rocky Mountains of Montana in the United States.It sits on the Continental Divide on the border between Jefferson County and Silver Bow County, six miles south-southeast of Butte in Beaverhead-Deerlodge National Forest at an elevation of 6,329 feet (1,929 m).
However it is possible to split the altitudinal gradient into five main zones used by ecologists under varying names. In some cases these level follow each other with the decrease in elevation, which is called vegetation inversion.
