If you go to the Board of Geographic Names site
(http://geonames.usgs.gov/), it indicates that all elevations are from
the National Elevation Dataset. (Which is probably what Garmin uses as
well.) NED doesn't really have the spatial resolution to resolve
features as small as the exact tops of
Hi everyone,
I completed the GNIS node import yesterday. Please see the wiki page [1] for
more details.
As several of you have messaged me and posted on this list, there are some
problems with this data. Let me try to explain my thought process:
