HI Vijeesh, Not sure about that one, I have always generated a full earth. If you do an osgdem --help you will see some options -gb and -ge could be the ones you need? If the initial image resoulution is low then I suspect that is the problem. Although it could be worth making sure you run gdal_translate on the image and gdaladdo, see if that helps? Also the amount of levels will determine the amount of LOD to generate, have a look at the -l option.
Let us know how it goes, I am still learning osgdem!

That image was georeferenced. So when i removed -xx and --yy as you told, I got the terrain. But my next question is my imagery file is only covering a small area and the elevation data is 3 arc sec srtm hgt file for 1degx1deg . So I'm getting the terrain with imagery on some portion and the rest is white. How to limit the terrain so it covers only the area referenced in the image file. Also the quality of the texture is very poor compared to the original tiff file. Is it because of the image resolution is low?. Thank you!
