The elevation of a geographic location is its height above a fixed reference point[citation needed], most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic system, vertical datum). Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.
Less commonly, elevation is measured using the center of the Earth as the reference point. Due to equatorial bulge, there is debate as to which of the summits of Mt. Everest or Chimborazo is at the higher elevation, as the Chimborazo summit is further from the Earth's center while the Mt. Everest summit is higher above mean sea level.
A topographical map is the main type of map used to depict elevation, often through use of contour lines. In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain in GIS.
Jean-Baptiste de Laubier, also known by his artist name Para One, is a French electronic music producer and film director.
Laubier first came to prominence as one of the main producers of French rap group TTC, and was responsible for producing their 2004 signature tune Dans Le Club. With fellow TTC producer Tacteel he made up the now defunct live/improvised electro outfit Fuck-A-Loop (whose only recorded material prior to 2007's nine hour digital album The Early Aughties was a 2006 remix of Ellen Allien's Down). In 2007, he remixed The Prime Time of Your Life by French house duo Daft Punk. In 2008, Para One got his biggest commercial hit by remixing #1-hit song Greatful Days by Japanese popstar Ayumi Hamasaki. This song was released on the album Ayu-mi-x 6: Gold.
He also produced the soundtrack of the film Water Lilies directed by Céline Sciamma in 2007. In 2011, the song "Always" from his and Tacteel's Fair Enough EP was featured in the same director's film Tomboy.
Apart from his musical career, Jean-Baptiste de Laubier also works as a film director. In 2009, he directed the short movie It Was On Earth That I Knew Joy for French brand Sixpack France. The movie was presented on February 20, 2010 at SCION Installation, Los Angeles.
