| Description | It is usual to describe geographical points in terms of their polar coordinates (latitude, longitude and altitude) referenced to a "datum ellipsoid", which is used to approximate the Earth's geoid. The latitude, longitude and altitude of a given physical point vary depending on which datum ellipsoid is in use. Unfortunately, a number of ellipsoids are in everyday use, and so it is often necessary to transform geographical coordinates between different datum ellipsoids. . Two different datum ellipsoids may differ in the locations of their centers, or in their shape; and there may be an angle between their equatorial planes or the meridians relative to which longitude is measured. The Helmert Transform, which this module implements, is a linear transformation of coordinates between pairs of datum ellipsoids in the limit of small angles of deviation between them. |
