Thanks! Sorta kinda... But also different.

The main idea was to solve the gap of how many trail systems have colored loops, or signed/colored loops made up of multiple "trails", and Trailforks (et al) has no concept of that. So the situation a user finds themselves in is being at a trail, with Trailforks up, wanting to follow the "Orange" loop (for example), and Trailforks doesn't show that.

Hopefully the "Orange" loop is documented as a route, but this stuff often gets missed, and is still awkward since the image of the map still doesn't match the signs.

So my goal was to show the map close to what's physically there, use OSM data as much as possible, and filling in gaps for what OSM doesn't capture, rendering it all into a static map that also happens to work offline. For some specific examples, compare these two systems and their print, Trailforks, and trailmaps.app maps:

RAMBA: [1], [2], [3] Shelden Trails: [4], [5], [6]

There is the same kind of gap when compared to RideWithGPS, Strava, Gaia, etc.

And also, I'm a volunteer with our local trails non-profit. I want anyone and everyone to be able to find maps so they can enjoy the trails. A /lot/ of trail clubs are starting to replace maps with a link to Trailforks, which I believe does riders a disservice because it both requires an app and account and (if a user is trying to view a map out of their home area on a phone) payment. It's literally locking the basic info about a trail -- the map -- behind a semi-paywall. By making a system like this for our local trails I've helped completely avoid that mess. And so I made the map generator open as well so other techy folks can do the same or build on this.

This generated-static-map system does have the downside of being single-person-ish manually managed, and the maps do NOT update automatically. But I also see this as a feature, just like the print maps and in-person signage they are designed to complement.

I've prattled on a little more about the what-why-etc over here on my personal blog if you're interested: https://nuxx.net/blog/2026/06/25/trailmaps-app-map-generator...

Your 'app' could have been a webpage (so I fixed it for you)
