Also, to add to that, osgdem relies heavily on GDAL to ingest raster data. GDAL has several tricks for combining multiple files or directories and referencing them as one dataset. For example:
https://gdal.org/gdal_vrttut.html I don't recall ever using that technique with VPB, but in theory it could be helpful.
