I don't really know enough about the NJ Landuse import to have an
opinion, but three comments:
if there is landuse=scrub, that's fundamentally confused. The
definition of scrub is not really the issue - OSM should reference and
adopt the accepted definition in the related professional fields. But
scrub is landcover (physical geography), not landuse (human
geography). If it's natural=scrub and this is a combined
landcover/landuse dataset, that's something else.
Reading the natural=scrub page, I don't find the presence of some
20-ft trees inconsistent with the definition. If it's mostly trees to
the point that the forest floor has reduced vegetation, then it's
crossed over into forest. But if there are a few trees and mostly
bushes, it's still scrub. It might be nice to add references to tags
that are the boundary of scrub to that page, with a clue as to how to
draw the line.
Is there a newer dataset available, and/or a way for people to start
with the old data and do things right (process, reviewed by towns)?
If so, that argues more for the removal/start over.
It's interesting that you say there are so many errors. The MassGIS
data has been very good in terms of quality, to the point where that's
not been a real issue, just how to handle it.
