The Geographic Calculator has become the standard tool for coordinate conversion worldwide, and it keeps getting better! Every GIS Professional that has concern with accurate geospatial data should have this product as part of their software toolbox. On a basic level, the Geographic Calculator converts individual coordinates, point databases, and map files from virtually any coordinate system, datum, and map projection, to any other.
You can transform between coordinate systems, calculate the distance and azimuth between coordinates, and calculate a coordinate at a specific distance and azimuth from known starting point. The Geographic Calculator also computes grid convergence, point scale factor, datum shifts, and grid shifts. Of course, the Geographic Calculator is professionally documented and supported.
