`osm-river-basins`: Website to show how are rivers in OSM connected
Posted by amapanda ᚛ᚐᚋᚐᚅᚇᚐ᚜ 🏳️🌈 on 21 August 2023 in English.Hi all, I’ve made a website which shows how all the waterways in OSM are topologically connected, or not:
More details are there, or on the backing github project. You can also run the programmes for yourself if you want to tweak it, or just show your region.
This tool can help you find possible tagging mistakes in river topology, like change in a name, or find places where 2 rivers aren’t properly connected up.
Data is updated manually by me when I remember.
What do yous think?
You can follow me on fedi/mastodon @amapanda@en.osm.town for news, or read this on the Discourse OSM Community Forum

Nice work - the colour coding makes it dead easy to pick up the missing links in a waterway.

Cool work! There is a question, what is the proper way to tag rivers going through waterbodies. With name tag or without, with some addidtional tag or without. There are several schols of thougt there… Bwt, Lithuanian basins: https://openmap.lt/baseinai.html And if you look at our river map https://upes.openmap.lt, rivers through waterbodies are symbolised with dashes (because this is river routing map)
