Similar for running or biking, there are certain limits that could help in dropping noisy points.\n\nThe difficulty would be that if you would get on a bus for example, and then continue, it should only drop the bus points, and afterwards the points are again close enough to each-other, so it can continue.\n"},"comment":{"url":"https://api.github.com/repos/mendhak/gpslogger/issues/comments/262445389","html_url":"https://github.com/mendhak/gpslogger/issues/328#issuecomment-262445389","issue_url":"https://api.github.com/repos/mendhak/gpslogger/issues/328","id":262445389,"user":{"login":"dbareis","id":295230,"avatar_url":"https://avatars.githubusercontent.com/u/295230?v=3","gravatar_id":"","url":"https://api.github.com/users/dbareis","html_url":"https://github.com/dbareis","followers_url":"https://api.github.com/users/dbareis/followers","following_url":"https://api.github.com/users/dbareis/following{/other_user}","gists_url":"https://api.github.com/users/dbareis/gists{/gist_id}","starred_url":"https://api.github.com/users/dbareis/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dbareis/subscriptions","organizations_url":"https://api.github.com/users/dbareis/orgs","repos_url":"https://api.github.com/users/dbareis/repos","events_url":"https://api.github.com/users/dbareis/events{/privacy}","received_events_url":"https://api.github.com/users/dbareis/received_events","type":"User","site_admin":false},"created_at":"2016-11-23T06:59:31Z","updated_at":"2016-11-23T06:59:31Z","body":"Why not do as I suggested and look if the user effectively backtracked\n(look at points either side to determine if the point being examined \"makes\nsense\", no need to look only at speed.\n\nOn Sun, 20 Nov 2016 at 20:56 mendhak <notifications@github.com> wrote:\n\n> Made an attempt now - although not going as far as asking the user for a\n> maximum distance/time as that may open up a whole avenue of extra\n> overheads.
