I'm not sure if GT has an implementation for this or not. However, you don't need to write it. The SEDRIS project has a "Spatial Reference Model" (SRM) with transformations not typically included in GIS packages, including ECEF. The main problem is that the SEDRIS SRM is not identical with the CRS model in 19111. At times in the past, I've explored what it would take to bring the SEDRIS SRM "under the wing" of 19111, so if you're interested I could give you a briefing.
Oh yeah, the SEDRIS SRM is ISO/IEC 14026. And it's freely available. Last I checked, the jar was about 500k. http://standards.sedris.org/license_stds.php?product=standards&filename=18026.zip Bryce [EMAIL PROTECTED] wrote on 03/12/2007 12:21:42 PM: > Is there existing code in GeoTools that performs conversion of > coordinates in Latitude/Longitude/Ellipsoid Height to Earth-Centered > Earth-Fixed coordinates?
