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.
Nose cone design – Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.
In 2016, the Indian Air Force allocated 11 acres (4.5 ha) of land for the construction of a new civilian terminal. [8] The new terminal covering an area of 19,000 m 2 (200,000 sq ft) along with aero bridges was constructed at a cost of ₹ 2 billion (US$23 million). [9] Aerial view of the airport. At 10,682 feet, it is the highest airport in India.
The most common and convenient datum which is internationally accepted is mean sea level which is a universal measure and based upon a common base line in the whole world determined by earth's gravitational model (see geoid) that gives the standard to measure elevation of a place above or below mean sea level.
Vertical references in Europe View from Newlyn harbour showing the lighthouse and Newlyn Tidal Observatory to its right, both painted red and white.. An ordnance datum (OD) is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps.
NAVD 88 was established in 1991 by the minimum-constraint adjustment of geodetic leveling observations in Canada, the United States, and Mexico.It held fixed the height of the primary tide gauge benchmark, referenced to the International Great Lakes Datum of 1985 local mean sea level (MSL) height value, at Rimouski, Quebec, Canada.
In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL [1] or HAGL) is a height measured with respect to the underlying ground surface.This is as opposed to height above mean sea level (AMSL or HAMSL), height above ellipsoid (HAE, as reported by a GPS receiver), or height above average terrain (AAT or HAAT, in broadcast engineering).
AMSL is an acronym for "Above Mean Sea Level", the elevation of a location above a standardized sea level. AMSL may also refer to: Alberta Major Soccer League, a Canadian soccer league; Airbus Military Sociedad Limitada, a former aerospace company based in Spain; Aéroport Montréal Saint-Hubert Longueuil, a Canadian airport
