(I made WaterwayMap.org) The data is 100% OpenStreetMap, and updated daily. Something missing on WWM.org means something missing on OSM. You can fix that yourself!

> What's interesting and somewhat amusing is that this map has determined that the section of the Soar that joins with the Trent just north of Loughborough is apparently unnavigable

The boat views only use the OpenStreetMap `boat` tag. If a section of river is missing from WWM.org, then it's likely the tag is missing from the OSM waterway. You can fix that!

(I made WaterwayMap.org) There isn't a legend, because all waterways are treated the same.

(I made WaterwayMap.org) Yeah, it's been very useful to make OSM data better.

> some streams are disconnected by other waterbodies where they should not be, as there seems to be little consensus on how to connect waterways through lakes and other waterbodies

Yeah, the OSM community is still discussing this: https://community.openstreetmap.org/t/should-river-lines-be-...

(I made WaterwayMap.org) The data is 100% from OpenStreetMap. I only have to deal with 1 dataset. I suspect people have imported data from Massachusetts into OSM, hence why you see the edge. You can edit OSM to connect things up yourself.

(I made WaterwayMap.org) The data is 100% OpenStreetMap. It's possible many rivers are missing the `boat` tag (which that uses). If you add the missing tag, then it'll appear on WWM.org tomorrow!

> For bigger rivers that I'm familiar with I was not able to make sense of that number. […] Maybe it's the total length of that waterway and all connected waterways?

Correct.

> “The "Navigable by canoe" filter seems to filter out everything”

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!

Nope, it's 100% OpenStreetMap data.

“Who mapped these?” All the data is from OpenStreetMap!

Lovely! I'm Irish, we don't have it as much. But I'd love to do a canal boat holiday. Doddleing along the canals, stopping in a lovely english country pub... oh I can dream.

I made WaterwayMap.org, and one of the view is for anything OpenStreetMap considers “boatable”: <https://waterwaymap.org/#tiles=planet-waterway-boatable> I know nothing about this topic, so if there's anything missing, I'm willing to add it.

Hello! I'm the creator of WaterwayMap.org.

The code is here: <https://github.com/amandasaurus/waterwaymap.org/> if you want to file a bug report or feature request. The main code to calculate the network is `osm-lump-ways`: <https://github.com/amandasaurus/osm-lump-ways>

Pretty sure Google doesn't use OSM

(I'm the creator). There's a few views which will bring in _named_ streams, the `waterway` & `name` tag views. I tried to calculate it with any waterway tag, which would include unnamed streams, but my computer ran out of memory. Maybe later.

(I'm the creator of this) Yes lots of rivers are missing those sort of connections through lakesᵉᵗᶜ, but that's not unique to USA. Please keep mapping to fix up things.

Hi! I'm the creator of this tool! I'm open to more feedback, and suggestions. Even related views.

Lots of people discovering OSM through this, which is great. This sort of tool is new, so we're all just fixing up lots of little tagging & topology mistakes which were hard to spot.

I'm the creator of this. Yes, it's precomputed on a computer, but it only takes ~30 mins to calculate each view. Most of that time is file I/O (which I really need to refactor)

There are 435,057,783 building=yes, and 1 building=oui.

The OSM community has standardized.
