Hi there, my name is Tyler. I’m an armchair mapper based in the Greater St. Louis region of the US state of Missouri who tends to focus on Missouri highways. I even contributed a fair bit to the wiki article on that topic. 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.

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. numbered route, or an Interstate route, I would love to take a look at it! Coherence 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. 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 one hundred large topology errors (e.g. missing concurrencies or incorrect routing through towns) and fewer than four hundred small topology errors with SSRs, and that’s manually doable. Geometry errors are not as important as topology errors to me, but I fix what I can.

My grade of Missouri state routes as mapped: B (there are scattered missing concurrencies even among numbered routes, but supplemental route relations are coming along nicely)

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