It would be an interesting problem to see / solve where in this map would a drop travel the most. By just clicking, I got one that travels from Cavour, South Dakota to Gulf of Mexico over a 3523 Kms journey. I am sure there must be something that is longer!
Edit - some of the routes stop at border of Canada - is this due to lack of dataset?
- Sharlin 5y agoThe longest route in this dataset is almost certainly from Northwest Montana to the Gulf of Mexico; see, eg. the beautiful illustration of watersheds in North America at [1]. Example: [2] [1] https://www.visualcapitalist.com/maps-worlds-watersheds/ https://www.visualcapitalist.com/maps-worlds-watersheds/ [2] https://river-runner.samlearner.com/?lng=-113.26136901231438&lat=48.47374874798547 https://river-runner.samlearner.com/?lng=-113.26136901231438...
- carl_dr 5y agoThe source of the Missouri River - Brower's Spring apparently - is probably close to the point where it's longest. I can't find it exactly on this map, but have got up to 5790km, from a point just by Yellowstone Airport. The code is at https://github.com/sdl60660/river-runner/ https://github.com/sdl60660/river-runner/, it would be quite possible to base a solver on that.
- samlearner 5y agoHa I appreciate you sharing the repo, but if someone is interested in finding a longest route, they should probably just go straight to the data source (USGS NHDPlus data/NLDI API)
- TimonKnigge 5y agoYou can click in Northern Montana for longer routes, e.g. Browning, Montana gives about 5587km.
- kcvv 5y agoThis is cool! Did you have some info on this or use some data to find this? I was randomly clicking points on center of US and many were just ending in a nearby lake. I only found a few that ended up in the sea..
