Looks nice but it's probably not really usable for navigation. I checked the Netherlands and Germany. You'd need more details for safely navigating on the water. But it definitely has potential. There are also some other specialized open street map based maps for - rails: https://www.openrailwaymap.org/ - cycling: https://www.opencyclemap.org/ - sea map (competes with this I guess, and is a bit more detailed for navi…

I've been waiting for the day that HN would have something tangentially related to the English and Welsh canal system so I could gush about it. For those that don't know, we have around 2500 miles of (mostly) navigable canals around the UK. They were built during the industrial revolution prior to the invention of trains such that we could transport coal and other goods relatively quickly and without damage (consider…
It’s always baffled me how the regard that the average Englishman holds for itinerant folk is wrapped in a big if statement: if (boat) … # All good else: raise TravellerAlert()

A few years ago, we decided to travel to Wales, mainly to visit the Doctor Who Experience, but also to pay Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch a visit (for the novelty factor). We flew to Stansted and then drove through the English countryside and had a truly magical moment, when we decided to stop for a short rest. In small town we drove onto a parking lot, and then followed the sign to a…
Who mapped these? In New Mexico we have a ton of dry arroyos that maybe have a couple inches of flowing water a few times a year. Zooming in at places I'm familiar with, a surprising number of them are mapped. I know of rez roads[1] nearby that aren't on OSM or any map I know of, but the ditch we used for cross country practice is. Wild! [1] Two-track dirt roads on the Navajo Reservation that are not regularly mainta…

In the USA, this is likely sourced from the National Hydrography Dataset: https://www.usgs.gov/national-hydrography/national-hydrograp...

The "Navigable by canoe" filter seems to filter out everything, which is a bummer, because I've always wondered how far up into the Sierras I could drop a canoe and still be able to paddle back to the bay area.
The data is 100% from OpenStreetMap. That map only looks at things with the `canoe` tag in OSM. There are a lot of waterways in OSM which do not have this tag. If you know of missing data, you can just edit OSM and it'll show up on WWM.org tomorrow!

If you zoom in you see a length in km next to each river. For small ones it looks like it is the total length of that waterway. For bigger rivers that I'm familiar with I was not able to make sense of that number. It is not the length, it's too big for that. Maybe it's the total length of that waterway and all connected waterways? It also does not change when I travel along that waterway. My example is the river Neck…
Correct.

I had a look at central Europe and this map not accurate e.g. motor boar = yes and it only shows w few parts of the same river.
Weird how so many streams end at the Massachusetts state line. Not the dev's fault of course. I've noticed a similar difference of how rock formations are recorded at state line boundaries on USGS maps. Dealing with different datasets from different bureaucracies is an intractable problem.
