The Hong Kong GPS Network and Reference Stations. The quantity by which a geodetic length is multiplied to obtain the corresponding grid length is termed a scale factor. The limitations in the width of the projection or grid permits a control of deviations of grid lengths from geodetic lengths., In other words, the geodetic length of a line, on the ellipsoid, multiplied by the appropriate scale factor will give you the grid length of that line on the map. And the grid length multiplied by the inverse of that same scale factor would bring you back to the geodetic length again..

For example, networks of GPS measurements are processed in X,Y,Z Cartesian coordinates but locations of network stations are usually transformed to geodetic coordinates (latitude, longitude and height) related to the reference ellipsoid. And may be transformed to E,N grid coordinates on a map projection. If the precisions of coordinates are known in one system, then precisions in the A geodetic reference framework forms the spatial foundation for the creation of any Land-Information System (LIS). Consisting of monumented points whose locations have been accurately determined with respect to a mathematical framework, this system permits the spatial referencing of all land data to identifiable positions on the Earth’s surface.
