Hello Lucie, When looking at your log I see that the tiff texture is reprojected...
started DataSet::createDestination(3) reprojecting to file temporaryfile_013c07_0100_deme.tif reprojecting to file temporaryfile_S4_06032_5215_20061018_m20_1_utm20.tif Time for after_reproject 8.389910 as recommended by Shayne, you should re-project your data, first it will save you some processing time and secondly it will allow you to detect projection problems more easily... To avoid aliasing artifacts when accessing data, you can also use gdaladdo to store the mip maps in the .tiff, like explained here : http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/osgdem (but it won't fix your projection trouble) Otherwise I believe there was some problems with GDAL 1.5 at least with some release ; particularly the 1.5.0 was buggy... If using known to work data, you still got strange result, try to update gdal lib... I've downloaded and tested on my machine (Debian 64bits - osg 2.9.7) your Boston terrain and it looks normal... but the files are probably not reprojected... You could also try to look at your data in a GIS tool like Quantum GIS http://www.qgis.org/ Just to see if everything is looking good ? Pierre.
