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).
Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. [1] [2] It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Game Technology Group at Sun Microsystems. Since 2010, it has been an independent open-source project under a BSD license.
An ordnance datum (OD) is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps. A spot height may be expressed as above ordnance datum (AOD). Usually mean sea level (MSL) at a particular place is used for the datum.

NASA WorldWind SDK Tutorial: This Tutorial was developed by the Institute for Geoinformatics from the University of Münster, Germany. It contains tutorials from setting up an Eclipse environment with the WorldWind API to building polygons from Linked Open Data geographic datasets. It contains important tips from beginners to advanced developers.
In 2002, as a project for the British Columbia Ministry of Sustainable Resource Management, Vivid Solutions Inc. created a software program to do automated matching of roads and rivers from different digital maps into an integrated single geospatial data set. The software team made the program flexible enough to be used not just for roads and ...
In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. [2] A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart. Definitions
Forward texture mapping iterates through each texel on the texture, and decides where to place it on the screen. Inverse texture mapping instead iterates through pixels on the screen, and decides what texel to use for each. Inverse texture mapping is the method which has become standard in modern hardware.
