Welcome to Lemmy! I recently posted about Wanderer also in another self-hosting community: https://slrpnk.net/post/7887187
As someone interested in self-hosting this, I have two questions:
How far is it suitable for say a local hiking association or a small municipal government to use this as a public trail database to promote regional eco-tourism efforts? Where I live the local government has something like that, but it is badly maintained. For that to work it would need to have the ability to easily find trails on an overview map and to allow posting notices about trail closures etc. (ideally even crowd sourced?) Maybe also some way to mark trails as official, if they are designated and sign-posted.
Unrelated: have you thought about allowing the live-tracking via apps like Phonetrack or OSMand? I think that would make it both more convenient for uploading tracks (at least where there is sufficient cell-coverage) and might add an interesting social aspect to it if you can share your live-location with other users.
P.S.: Would be great if you could add it to https://translate.codeberg.org/ for adding additional languages easily.
