import caaml from snowpack shows wrong snow depth labels
This issue was reported by Frank Techel.
Steps to reproduce the problem:
- download caaml-file from http://snowpack.wd.op/full.html?file=share%2Fsnowpack-imis%2Foutput%2FJAU2.pro (profile view)
- import caaml in niviz.org
Expected result: Visualisation should be as in SnopViz (screenshot 1)
Actual result: The profile is not being recognised as going to ground. As a consequence the labeling of the layering depth shows 0 cm at the top, and negative values below (screenshot 2).
