ignore about what Spaghetti Cat reported. Its basically outright incorrect!!!! Now onto your question... in the start, you said that you need to not locate any information on the information superhighway. try doing a glance for on "geodesy" or "WGS84 conversion". or you may basically get any kind of geodesy texts available (yet they are severe priced). yet another poster said CORPSCON. This application works fantastic. yet in case you wanted to do your man or woman application, you're going to ought to appreciate coordinate platforms and a thanks to remodel between them. back, i recommend a geodesy textbook to study this. In a nutshell... i will anticipate that your connection with Cartesian Coordinates is an section planar coordinate equipment, and under no circumstances an ECEF (earth-established earth-mounted) coordinate equipment. In a nutshell, GPS works in an ECEF cartesian coordinate equipment. Your community cartsian coordinate equipment is indirectly concerning to this. First, you would ought to remodel the ECEF position to geographical coordinates (selection, longitude, correct) in to WGS84 (the reference ellipsoid for GPS). then you extremely'd ought to remodel those coordinates to even if reference ellipsoid is used for the community cartesian coordinate equipment you're utilizing. finally, you'll then remodel from that ellipsoidal equipment to the community equipment you're utilizing.
