Hi Lucie, Did you attempt to reproject the tif file using gdalwarp? Try that and then use osgdem with the new reprojected file to see if that works.
I didn't receive your attachment. Please resend to [email protected] and I'll take a look at it. If you can, send me the actual tif and dt1 files... -Shayne -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of lucie lemonnier Sent: Thursday, July 08, 2010 9:45 AM To: [email protected] Subject: Re: [osg-users] [vpb] .tif and .tfw Hi, I also tried with dem and orthoimage downloaded at: http://www.geobase.ca/geobase/en/index.html I get the same problem, the projection doesn't work.
