Hello,

if you select just survey, then all maps consisting of scraps in this and
sub-surveys should be ordered by average altitude. But this may easily
cause that some overlapping is not done correctly. But it is also possible,
there is some bug and it is not done correctly. Are you able to post some
minimalistic sample, where depth sort fails?

The only way how to manually order maps in the output is to create
upper-level maps (in your case probably what you mean by <region>-Hautplan)
consisting of lower level maps in the correct order.

HTH, S.
