OK, say I go wandering some recreational trails with my GPS. Some of them are
well-marked, at the trailheads and along the way. Others are not so well-marked, but
are nonetheless official trails with names, etc. For the latter, info is available
in published maps and local government-produced GIS data.
How do we obtain the trail names and other data? Why is copying the name of the
trail from the physical sign different than copying the name from a map depiction?
>From the GIS shapefile?
Same question applies if I trace the trails using public domain aerial imagery
(I'm fortunate to live in a coverage area for USGS Urban orthophotos).
