GeographicLib provides a utility GeoidEval (with source code) to evaluate the geoid height for the EGM84, EGM96, and EGM2008 Earth gravity models. Here is an online version of GeoidEval . The Tracker Component Library from the United States Naval Research Laboratory is a free Matlab library with a number of gravitational synthesis routines.
GOES-18 (designated pre-launch as GOES-T) is the third of the "GOES-R Series", the current generation of weather satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The current and next satellites of the Series ( GOES-16 , GOES-17 , GOES-18, and GOES-19 ) will extend the availability of the Geostationary ...
The geoid is often expressed as a geoid undulation or geoidal height above a given reference ellipsoid, which is a slightly flattened sphere whose equatorial bulge is caused by the planet's rotation. Generally the geoidal height rises where the Earth's material is locally more dense and exerts greater gravitational force than the surrounding areas.
It will use a geoid model accurate to 1 centimeter (0.4") to relate orthometric height to ellipsoidal height measured by GPS, eliminating the need for future leveling projects. This geoid model will be based on airborne and terrestrial gravity measurements collected by NGS's GRAV-D program as well as satellite-based gravity models derived from ...
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.This standard was originally developed in the 1970s to support aircraft radar simulation and prediction.
CONUS, a technical term used by the U.S. Department of Defense, General Services Administration, NOAA/National Weather Service, and others, has been defined both as the continental United States, and as the 48 contiguous states. [16] [17] The District of Columbia is not always specifically mentioned as being part of CONUS. [17]
This list of Conus species is a listing of species in the genus Conus, a genus of sea snails, ... Conus alexisallaryi (Cossignani, 2018) [18] Conus alfi (Thach, 2016)
Lividoconus is a subgenus of sea snails, marine gastropod mollusks in the genus Conus, family Conidae, the cone snails and their allies. [1]In the latest classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Lividoconus has become a subgenus of Conus as Conus (Lividoconus) Wils, 1970 (type species Conus lividus Hwass in Bruguière, 1792 ...
