[OSM-dev] Simple app for "making contributions" (not to display maps)

not need to stress the inaccuracies of GPS - GPS traces is how this
whole OpenStreetMap started, long before we even had aerial imagery. To
this day some of the older hands in OSM consider using aerial imagery a
not quite sportsmanlike way of adding data a.k.a. "cheating" ;)

Automatically recorded tracks, even without any extra information, can
be useful but of course it always requires someone with local knowledge
to translate a raw GPS track into something that can be added into the
database proper. Your user's contributions would be immensely more
valuable if there was a way for them to at least record the information
whether they're currently on a path or travelling cross-terrain.
(Sometimes this can be guessed from the speed of movement but not always.)
When mapping on my own with GPS I always used the waypoint marker button
on the GPS to mark intersections; this makes it easier to work witht the
data later. However this information will not find its way into the
standard GPS trace background in editors; it is only available when you
work with the track directly.
