Hi there, my name is Tyler. I’m an armchair mapper based in the Greater St. Louis region of the US state of Missouri.

Map Interests

I have been doing a lot of manual QA on roads in Missouri. If you have a quality concern for a Missouri state route, U.S. Route, or an Interstate route, I would love to take a look at it! Coherency and consistency of state-maintained routes are very important to me. I’ve especially taken to fixing up our supplemental state route network, as many other maps I’ve seen handle SSRs remarkably poorly outside of populous places (even Google Maps which is unfortunately used everywhere). There are thousands of SSRs, but I am finding and fixing the egregious errors first using Overpass Turbo. Based on my triaging, there are fewer than a hundred large errors and fewer than four hundred small-to-moderate errors with SSR topology, and that’s manually doable in a few months. Geometry errors are not as important as topology errors to me, but I fix what I can.

If I make a mistake or you have a concern with an edit of mine, please reach out to me directly in a discussion thread or a message. I want to maximize the usefulness of the OSM database however I can, so please let me know if an edit I made steps on any toes.

My grade of OSM’s Missouri routes: B- (there are sporadic missing concurrencies even among numbered routes, and SSR relations are missing)

P.S. Did you know there is only one place in the state of Missouri where three supplemental state routes are concurrent? It’s among B, C, and ZZ, underneath U.S. 61 as seen here.
