Use Strava heat maps with caution as they are a record of where people have ridden but doesn’t reflect the correct permissions of a way. regards,Sebastian On 27 Feb 2023, at 9:09 am, Adam Horan wrote:According to https://wiki.openstreetmap.org/wiki/Strava and

I'm another big user of Strava for tracing... so thought I'd chime in with my approach. These days, not so simple to get access to the good heatmap direct in editors, since they restricted the higher zoom levels to when you're logged in. So since that change, when I'm in a rambling mood (which is

Hi Adam That was my take on why the 'heat' is no longer there. The fires of 2019-20 burnt that area fairly badly. The scrub in places is now very tough going, but would have been easier in say mid-to-late 2020. cheers Tom Canyoning? try http://ozultimate.com/canyoning Bushwalking? try

My understanding of the Strava heatmap is that it only shows the last year's worth of tracking. The changeset in question was from July 2021, which was around 18 months after the fires that swept through the area. The scrub would probably have been negotiable then, but less so in recent

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

This page https://support.strava.com/hc/en-us/articles/216918877-Strava-Metro-and-the-Global-Heatmap says that "The Global Heatmap shows 'heat' made by aggregated, public activities *over the last year.*" So it's possible there were routes showing when the original mapper mapped this but they've

Hi, Having a look at the Strava heat map, I can't see any activity at all. Select labels and hybrid to see the OSM layer, https://www.strava.com/heatmap#17.00/150.12413/-33.87746/hot/all https://www.strava.com/heatmap#15.99/150.14939/-33.91318/hot/all Nor can I see any sort of trail using the

My view is also that Strava heatmaps are insufficient on their own to prove a track. They do show that a reasonable number of people have passed along a particular route in recent times. They don't prove a path or track, and they give no indication of permissions. However I did look for details

I am not familiar with the use of heatmaps for mapping but, if it involves adding non-officlal trails, then I consider it potentially dangerous and not suitable for OSM. I have a strong view that mappers and publishers of maps have a public safety responsibility. There should be nothing
