in general, surface is a poor match to the needs of geologists,
as there is rather a bit more to geology than just the surface.

ditto for agricultural usage, surface is just odd and out of place.
some years a field may be corn, others soy beans, still others
something else. farmers do care about soil types, but a typical
modern soil type map is complex and something that doesn't
seem appropriate for openstreetmap.
