Thanks, did not know that. But since both products were originally 2
bytes ints, the mix can also be scaled to 2 bytes without loss of
original precision.
EUDEM is an "hybrid product based on SRTM and ASTER GDEM data fused by
a weighted averaging approach"

but the ASTER grids have lower real resolution than the SRTM (despite
being distributed as 1 arc sec grids) and the later are originally
int16 , so scaling to 2 bytes ints should be OK.
