TatukGIS Free Coordinate Calculator is  free application for Windows converts interactively the coordinates of a point between the coordinate systems. Version 2 has the same coordinate system support as the TatukGIS Developer Kernel (v.9) and TatukGIS desktop Editor (v.2) products, which means that nearly 3,000 pre-defined map coordinate are used worldwide (including all U.S. State Planes), with a simple selection from a drop down list. The settings for each of the U.S. State Planes can be found at: http://www.ngs.noaa.gov/PUBS_LIB/ManualNOSNGS5.pdf (refer to pages 63 – 72).

The calculator also provides coordinate projections of 120 supported projections and 350 supported datums. The support reflects EPSG codes and OpenGIS WKT coordinate system definitions. For batch conversion of large amounts of coordinate data (for many points) in a single operation, run the ‘CSConverter’ script in the TatukGIS Editor product. This script is one of many packaged with the Editor product.
