Would it be possible to introduce a time filter to heatmaps so that trails that fall out of favour fade out?
I live in an area surrounded by forests and use the heatmap facility extensively to find new routes to run / cycle off the main fire trails. However, due to forestry work over recent months and years and the inaccessibility of some routes due to tree growth, this has become an increasingly unreliable way to plan a run - routes that were popular can now no-longer be navigated.
I would propose at least a 12-month rolling filter (a bit like the rolling 90-days for local legend) to ensure that all seasons are captured.
