What is the difference between this three methods of transformation?
I am now setting parameters for Philippines Reference System of 1992 in GeoCalc of GeoComp Systems.
Although I'm sure that my parameters are correct, I can get a fine result that is corresponding with our government conversion results.
One thing that catches my attention is the transformation method:
In one of my office mate geocalc that runs on 32 bit, I saw a "MOLODENSKY method"
Then in our Government Website "transformation parameters are applied to "GEOCENTRIC CARTESIAN COORDINATES".
Then on the Geocalc software I'm using, I cannot change the only one transformation method that is "Bursa-Wolfe".
Hope you can help me understand the difference between this three. And can you site some website wherein I can somehow connect them.
Thanks in advance
