[talk-au] Mapping tracks from Strava heatmap

[forster at ozonline.com.au]

Hi

Am I missing something? I looked at way 952248376 and found a user  
Pieseczek with 2 changesets and 4 new ways over a year old. If there  
was any reference to Strava heat maps then I missed it. Is there any  
indication whether Pieseczek is resident in Australia apart from the  
likely origin of the name?

If the ways are solely based on heatmaps, they should be deleted  
because they can not be ground truthed. But they appear to map ridge  
lines. Were they made from the satellite photos or contours? Ridge  
lines can be ground truthed and belong on OSM.

I agree with Cleary on mapping of illegal trails but that may not be  
relevant in this case.
