DTED

Index DTED

DTED (or Digital Terrain Elevation Data) is a standard of digital datasets which consists of a matrix of terrain elevation values, i.e., a Digital Elevation Model. [1]

Aircraft

An aircraft is a machine that is able to fly by gaining support from the air.

Digital data

Digital data, in information theory and information systems, is the discrete, discontinuous representation of information or works.

Digital elevation model

A digital elevation model (DEM) is a 3D CG representation of a terrain's surface – commonly of a planet (e.g. Earth), moon, or asteroid – created from a terrain's elevation data.

EGM96

EGM96 (Earth Gravitational Model 1996) is a geopotential model of the Earth consisting of spherical harmonic coefficients complete to degree and order 360.

Endianness

Endianness refers to the sequential order in which bytes are arranged into larger numerical values when stored in memory or when transmitted over digital links.

Geoid

The geoid is the shape that the surface of the oceans would take under the influence of Earth's gravity and rotation alone, in the absence of other influences such as winds and tides.

Line of sight (gaming)

Line of sight, sometimes written line-of-sight or abbreviated to LoS, is the visibility (that is, who can see what) on the playing field in wargames and some role-playing games (RPGs).

National Geospatial-Intelligence Agency

The National Geospatial-Intelligence Agency (NGA) is both a combat support agency under the United States Department of Defense and an intelligence agency of the United States Intelligence Community, with the primary mission of collecting, analyzing, and distributing geospatial intelligence (GEOINT) in support of national security.

Radar

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects.

Reference ellipsoid

In geodesy, a reference ellipsoid is a mathematically defined surface that approximates the geoid, the truer figure of the Earth, or other planetary body.

Scientific modelling

Scientific modelling is a scientific activity, the aim of which is to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate by referencing it to existing and usually commonly accepted knowledge.

Scientific visualization

Scientific visualization (also spelled scientific visualisation) is an interdisciplinary branch of science.

Signed number representations

In computing, signed number representations are required to encode negative numbers in binary number systems.

Simulation

Simulation is the imitation of the operation of a real-world process or system.

World Geodetic System

The World Geodetic System (WGS) is a standard for use in cartography, geodesy, and satellite navigation including GPS.
