[talk-au] Mapping tracks from Strava heatmap

[Adam Horan]

According to https://wiki.openstreetmap.org/wiki/Strava and
https://wiki.openstreetmap.org/wiki/Permissions/Strava there is permission
to trace from the Strava heatmap.

(Which is fair enough given the extensive use they make of OSM maps for
display and routing)
