Use this Google Mapplet to show the local coordinates for any point on Google Maps. Supported projection types include Cassini-Soldner, Mercator, Oblique Mercator and Transverse Mercator projections types on user selectable geodetic datums. The datum transformation between the WGS84 datum used by Google Maps and the local projection datum is done using the Standard Molodensky transformation. Parameters for the datums and ellipsoids are taken from the University of Colorado. The available default projection parameters are limited but it is possible to define new projection parameters and to save them into the local browser cache for reuse.
