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.

The software team made the program flexible enough to be used not just for roads and rivers, but almost any kind of spatial data: provincial boundaries, power-station locations, satellite images, and so on. The program was named JUMP (JAVA Unified Mapping Platform), and it has become a popular, free Geographic Information System (GIS).
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.

HP-GL is related to AGL (A Graphics Language), an extension of the BASIC programming language. AGL was implemented on Hewlett-Packard minicomputers to simplify controlling a plotter. AGL commands describe the desired graphics plotting function, which the computer relays as several HP-GL instructions to the plotter.
