Lucie, If you're on a flat earth, you shouldn't be using the convertLatLongHeightToXYZ method. This is only used for mapping spheroid coordinates to geocentric (origin is at the center of the spheroid) coordinates. Because you were referencing this method, it was assumed that you were using this type of mapping.
If you want to get X,Y from a Lat,Long pair, you need to use some other projection or mapping. You could use a Plate Carree projection or something similar http://en.wikipedia.org/wiki/Equirectangular_projection. May I also suggest that you use something like GeoTrans or GDAL to assist you in what you need to do. -Shayne -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of lucie lemonnier Sent: Friday, October 01, 2010 3:06 AM To: [email protected] Subject: Re: [osg-users] convertLatLongHeightToXYZ Hi, In fact, my model is not spheroid, it is a flat terrain. That's why I need simply the position. Thank you!
