[talk-au] Mapping tracks from Strava heatmap

[Michael Collinson]

I use Strava heatmaps only as a "referential" source, i.e. seeing 
potentially missing or badly misaligned paths and then taking a walk 
that way. In addition to other comments about using them directly, I'd 
also wonder whether Strava copyright allows it but have not explicitly 
analysed.

In Sweden, I have found them a great referential source, but then we 
have "all man's right" and off-path walking is not generally an issue so 
there are many useful informal paths.
