[OSM-talk] Mapping IoW (I'm a new person with possible interest in doing something)

If you map an area and the GPS coordinates are time stamped, and you also 
make a POI and called it footpath, surely that should be enough information 
to confirm one went out and gather the information for a footpath.

Of course one cannot take information from a copyright map but they can use 
copyright maps to find the information they need to collect. If they can't 
find the information on the ground then there is a chance that the 
copyrighted map is wrong. I know companies use digital finger printing 
(adding of non-existent features) but companies also make mistakes from time 
to time.

That was all I was suggesting. Of course one must be very careful when it 
comes to collecting information and one must always keep records of sources 
used in case of a complaint.

Kind regards

I agree with Dan: if you're using copyrighted maps to find things to
survey, please collect evidence of the path status, road name, etc.
from the real world too.  If there's no evidence there, don't blindly
copy it from the map no matter how sure you are it's correct  - it
might be an easter egg.  Sad but true.
