Hi,

I have generated several terrain datasets with osgdem and have
encountered issues with data quality.  I have noticed that the level of
decimation and compression to the airborne DEMs and imagery is a
function of the input tile sizes and the number of LODs.  The smaller
the size of my input data and the more LODs I generate, the better the
output model quality.

Is this expected behavior?  Are there any quality settings I specify for
osgdem?

Thanks,
Andrew
