I think there's more tags that should be removed. Off the top
of my head:

* width (wildly inaccurate and in the wrong units)

* condition (wildly inaccurate and not kept up to date)

* source:* (eg source:maxspeed)

* gnis:* (all of them)

* massgis:* (all of them)

With the last two, I assume it's a bad idea to have a copy of lots
of stuff from a different database that we don't render and is
unlikely to ever get updated. In my mind these are in the same
category as the "source" tags. IE they are source info that were
used to make an edit, and become increasingly out of date as time
goes by and/or people edit the map.

With the first two (width and condition) we should leave them in if
they were entered by a person. Condition is something that changes
way too often to be imported en-mass. This data should only be in
the database when entered by a human, because then it's much more
likely to be kept up to date.

I'm not an authority on this stuff, but I just wanted to make sure
these are being considered. If somebody knows the current state of
the discussion/consensus on this stuff, we should do what they
say!


Are the elevation tags in the right units? I got the impression
that they were accurate enough to be worth keeping, but I don't
recall if the units are correct. If the units are wrong (eg its in
feet but the spec says meters) then the automated edit should fix
it.
