I can just now hear, nevertheless, a chorus asserting that the
information is available by other means and therefore does not
belong in OSM. An adit or a cave entrance (that isn't a sinkhole)
pretty much has to go into a hillside, and a waterfall or a dam
flows downhill, so with information about local topography, the
direction can be determined.
In many parts of the world there may not be elevation data with an
open license of suitable resolution to make this determination for an
adit.
It's not true that an adit always enters the hill in slope direction. I
know of many adits entering at an angle. So this approach does not
really help. We decided to use a different symbol for adits without
direction information than for directed adits.
