[OSM-talk] Route/flight tag

[Andy Robinson]

There is no justification for GPS traces collected in the air making their
way into OSM. They do not represent any aspect of the physical landscape
that we are mapping (other than once the aircraft has landed). It would be
easy to add a small note on the upload page to confirm to users that GPS
traces from the skies are not wanted and will only confuse and if
appropriate a link away from OSM to a better repository for their traces if
one exists.

Cheers

Andy
