Blue Marble has compiled an extensive database of coordinate system parameters (coordinate systems, datums, ellipsoids, units) over the last six years through the compilation of information from many sources (mostly governments, oil companies, and exploration firms) and the contributions of thousands of customers in over 60 countries. The database is available for free from our website at: http://www.bluemarblegeo.com/products.asp?ID=downloads. It's a simple text file (called geocalc.dat) in a simple self-explanatory format. It's used within all of our products but feel free to look it over. You can also download a free evaluation copy of the Geographic Calculator to view the parameters as it has designers that offer a handy interface. Good luck, Jeff C.
