Geodesy

GNU Gama is a package for adjustment of geodetic free networks (acronym Gama is formed from words geodesy and mapping). GNU Gama is written in C and currently supports only adjustment in a local carthesian coordinate system; adjustment in global coordinate system is part of new development...

A collection of geodetic functions that solve a variety of problems in geodesy. Supports a wide range of common and user-defined reference ellipsoids. Most functions are vectorized. Functions include:Angle Conversions deg2rad - Degrees to radians dms2deg - Degrees,minutes,seconds to degrees... Platforms: Matlab

It performs transformations of geodetic coordinates from one ellipsoid to another using 7 datum parameters. It is also called Helmert 7 parameters transformation or datum transformation (in geodesy and cartography). Platforms: Matlab

This function uses the Vincenty direct algorithm to solve the "forward geodesic problem," which is the problem of computing the endpoint of a geodesic (shortest-distance) path on the ellipsoidal earth, given the start point, a path length, and a starting azimuth. This process is also called... Platforms: Matlab

A set of functions to calculate coordinate transformations between different reference ellipsoids and different projections, including tools on:- transformation from cartesian to geographic coordinates and back- transformation from geographic coordinates to transverse mercator mapping or lambert... Platforms: Matlab

NGRAV computes the normal gravity value (in m/sec^2 unit) of a point with the geodetic latitude defined in GRS80 ellipsoid,which is the more up-to-date and internationally adopted reference ellipsoid.The normal gravity value is used for the computation of the gravity anomaly which removes the...

In 1975, Vincenty published a rapidly converging algorithm for computing the distance between points on an ellipsoidal earth. The algorithm is precise to within a few millimeters. Since then, his algorithm has since seen significant implementation in geodesy and engineering. After adjusting the... Platforms: Matlab
