3. Any other major issues?
The TerraGear scenery bug with the Great Lakes (and possibly other
large inland lakes?) is pretty serious -- it leaves many midwest U.S.
and central Canadian cities perched on giant cliffs overlooking the
lakes.
This must be an issue with the 'new' Shapefile version of the vmap0
database. Perhaps something did not get categorized properly in the
conversion? I've seen some odd water areas in the v0.9.10 scenery in
place they shouldn't be. I haven't had a chance to look into it
though. But ultimately this will need to get fixed at the data level.
Perhaps the great lakes got categorized as ocean? That would explain
why terragear forced the altitude to zero. Lakes are left in place with
perhaps a bit of leveling and smoothing. Another (less likely?) option
is that the SRTMv2 data for those areas are zero elevation??? Maybe
someone could do some poking around and at least narrow down where the
problem lies. Lakes marked as oceans? or bad srtm data?
