There is this: http://wiki.openstreetmap.org/index.php/Proposed_features/Surface_Mining
But I don't think it covers the "bog" as a whole. Perhaps a big
polygon natural=lowland_bog and within that, areas of
landuse=surface_mining with resource=peat ? This brown area, visible
on landsat would represent the current mined area, open to the air.
I think peat is the same as turf, used in domestic fires?
