Would love to see this for the SF Bay Area - lots of great cycling around here and I'm unsatisfied with using Strava to create routes!
One of the most frustrating things for me with snapping to official paths is not being able to modify it for common workarounds (for instance, going across the Golden Gate bridge, everyone takes a shortcut through a parking lot, but every map routing platform I have used forces me to go the official route and messes up my nav)
And Davis, naturally. ;)
I'm around hill country TX now where there is typically a patchwork of bike lanes segments that start and stop without much attention given to continuity of (sub)urban planning, walkability, safety, or design consideration for non-motorized users.
It feels like the approach OP is taking won’t be able to take this short cut into account.
I too am interested in linking up good bike trails. Mostly for the east bay gravel systems. Today, I save GPX or geojson from routes I find on Strava and import into a map client (CalTopo). It’s a okay solution but my problem is in finding more alternative routes.
Which parking lot? I ride the bridge a ton from the Presidio to travel up to Marin!
It's the parking lot near Lincoln Blvd and Merchant Rd. If you come from Chrissy field, you wouldn't cut thru it, but my route is Arguello -> Washington -> Lincoln then through the parking lot onto the path by the battery onto the bridge
