Hi,

I have a High resolution digital elevation model which I would like to 
integrate into a larger low resolution Dataset.

Unfortunately my Hi-Res inlay has no rectangular shape, so all uncovered ereas 
are (or at least appeare as) black.

If I compile my dataset, the black area of my HiRes inlay override the valid 
values of the LoRes Global DEM. This causes the area around my HiRes Inlay to 
be flat. Outside of this flat area the dem contains the valid LowRes Values.

Is it possible to configure VPB or modify my HiRes Inlay only to use the inlay 
if it contains at that location valid data?

Thank you for your help!

Cheers,
Torben
