I made wanderer - a self-hosted trail and GPS track database
Over the last two months, I developed wanderer. It is a self-hosted alternative to sites like alltrails.com or in other words a self-hosted trail database. It started out more as a small hobby project to teach myself some new technologies but in the end, I decided to develop it into a fully-fledged application.
Core Features:
Manage your trails
Extensive map integration and visualization
Share trails with other people and explore theirs
Advanced filter and search functionality
Create custom lists to organize your trails further
Would be nice with activity pub support for sharing planned and recorded trails. Cone to think of it. Does it make that distinction? Planned vs recorded? How about a planning, route finding mode?
I'm not sure if I understand your question correctly. Do you mean creating a trail from scratch on the map without recording it before? That is indeed on my roadmap.
Unless Pocketbase adds support for ActivityPub, you are probably better off just adding a share to Mastodon, Pixelfed etc. button in the frontend and let an external software handle this.
