View Full Version : Geocentric and Geodetic

04-24-2004, 09:27 AM
This is a tired old question, and OT, but I will ask anyway.

Does anybody know of a web site that offers:
1. Geocentric to Geodetic conversion using multiple DATUMS.
2. Source code in something other than FORTRAN for this?

I'd be happy to just find the snippet with the correct constants. I need to account for the difference between Clarke 1866 and WGS 84.

I'm not sure about this, but try vterrain (http://vterrain.org/) or USGS (http://www.usgs.gov/) .

Not sure as well, but you can also try :

http://www.remotesensing.org/gdal/ (rasters)
http://www.remotesensing.org/ogr/ (vectors)

It handles reprojections between different coordinate systems, so it might be able to help you out.
