﻿ Group Parameter Determination
 Group Parameter Determination

The group "Parameter Determination" contains functions to return values of in GeoDLL predefined and user-defined coordination systems, geodetic Reference Systems and ellipsoids.

Characteristics of the function group

 • Determination of the GeoDLL codes equivalent to an EPSG code
 • Parameter, notation and range validity of Coordinate Systems
 • Parameters of Reference Systems and Reference System Transitions
 • Semi-axes and flattening of earth ellipsoids
 • Designation and parameter of Measurement Units
 • Formatted text representation of a Coordinate Reference System
