Page 185: Working With Determine Coord System
Working with Determine Coord System 28.1 An Overview of the Program Description • GPS measured points are always stored based on the global geocentric datum known as WGS 1984. Most surveys require coordinates in a local grid system, for example, based on a country’s official mapping datum or an arbitrary grid system used in a particular area such as a construction site.
Page 186 Characteristic Description Principle Transforms coordinates directly from WGS 1984 to local grid and vice versa without knowledge about the local ellipsoid or the map projec- tion. Procedure: 1. The WGS 1984 coordinates are projected onto a temporary Transverse Mercator projection. The central meridian of this projection passes through the centre of gravity of the common control points.
Page 187 Characteristic Description Requirements • The position is known in WGS 1984 and in the local system for at least one point. Three or more points are recommended in order to obtain redundancy. • Additional height information for one point enables the transfor- mation of heights.
Page 188 Characteristic Description • One point: Heights are shifted to fit to the height control point. • Two points: Average height shift between the two height control points. • Three points: Tilted plane through the three height control points to approximate the local heights. •...
Page 189 Requirements to deter- • To determine a transformation it is necessary to have common control points whose mine a transformation positions are known in both WGS 1984 coordinates and local coordinates. • The more points that are common between datums the more accurately the transforma- tion parameters can be calculated.
