The default scenery in the base package uses the vmap0 data at maximum
available resolution.  Curt's official scenery for the rest of the
world does not, yet, but this scenery does:

Note that the vmap0 scenery is nominally 1:1,000,000 resolution, like
the World Aeronautical Charts (WAC's).  In fact, it *is* the WACs, at
least around here -- I bought the Canadian WAC for the area around
Ottawa, and it contains exactly the same polygons and errors as the
vmap0 dataset, right down to a missing city to the west of Ottawa.

At that resolution, you cannot expect every twist and bend of a road
or riverbank to be modelled accurately.  vmap0 does a much better job
of the Great Lakes shorelines than the other dataset we were using,
but it can be a bit off on other stuff -- it's not unusual to find a
road 100m or so off of where it should be (possibly much more outside
North America).


All the best,


David
