Oh I did awhile back, I usually clear caches when bouncing my profile over to the old laptop I take on the boat. That was from when I first mentioned it.

I do not know where CRT got their data set from. We did not use CRT map data to populate canalplan because it was not available when we started. We didn't bulk import any map data from anywhere apart from previous versions of canalplan. We used openly available public mapping data and reference materials to add places and canals. So the Melton Mowbray navigation was added using data from the society website, Wikipedia and old maps. Similarly the Chesapeake & Ohio was added the same way. I did them both, along with the Shrewsbury canal, the Bude canal, the Newport branch. As its possible that some of that positional data is based off openstreetmap we consider the canalplan data sets as potentially a derivative dataset which is why we publish them as required by the openstreetmap derivative licence It's taken over 20 years to get the data to where it is. In our boat blog there are maps from 2007 using data pulled from Canalplan at the time and they are full of straight lines cutting across the canal line. Other data such as railway stations and bus stops are from national rail and NAPTAN data

It was worse than that, it used to say all planning apps were plonkers too

I'm not sure what you mean, the canalplan locations have lat and longs which are controlled by where they are on the map. The only link between a canalplan location and CRT locations is the CRT asset ID which were mapped by using Geospatial functions taking the canalplan coordinates and CRT data and finding the closest location base on great circle distances. We used to plot maps using Google maps until they started charging and we were plotting maps using Google back in 2007. Now we use our own map server with our overlay lying on top of open street map tiles which we regenerate once a week for UK and Ireland and once a month for Europe, Australia and North America You can change the default unit for planning. It defaults to miles and furlongs in the UK, and other units for other countries. If you use the route input screen rather than the wizard you don't need to select any country at all. Because canalplan is a combination of gazetteer and route planner. Yes the UI is clunky, it's something that needs working on but there are just two of us doing the whole thing in our spare time and the backlog of feature requests , plus fixing up 20 year old code, takes up a lot of time.\ - for example moving to headless chrome running on the server to generate PDFs

No, we took CRTs location codes but that is all and mapped those back to canalplan locations using lat and long coordinats and names. Canalplan predates CRTs publicly downloadable datasets by many years. The first set of wireframe maps for Canalplan were developed by me in the very early 1990s on an Atari ST

There are quite a few places in Canalplan which have names which we created because there wasn't anything but we wanted to add in something to break the marker places up. It's interesting to see where these have appeared in other canal based sites. And a very tasty pie it is too https://canalplan.org.uk/waterway/2jmg

You misunderstood, you have data in your data set that came from Canalplan and from nowhere else as I created it in Canalplan. There is a straight line on Melton Mowbray navigation in your app which was exactly the same as the canalplan dataset until I added to it last night. As I said, at least you've now credited canalplan for our dataset. As for contacting us canalplan has an integrated bug tracker where you can make feature requests, report bugs, etc, and also a forum for discussing things to do with the site.

Hardly for "Comparison only". Data for abandoned waterways such as the Newport branch of the Shroppie, the Shrewsbury canal and the Melton Mowbray navigation are pure Canalplan data. I know because I put it all in because they do not exist in CRT data sets. At least you are now crediting where you got the data sets from, even though its pretty much hidden away Also, I think if you've created a derivative dataset from Openstreetmap data then you are expected to make it available for download

So please explain exactly what you meant when you said "Canalplan data pipeline" Oh you mean in this tiny bit of almost hidden hard to read text

Canalplan data pipeline? Excuse me?

I think he has a nut loose

So you just took our Data and used it and didn't think you needed to credit us for it until now, and I don't see anywhere on your site where you actually credit us. In fact it looks like you've taken more than just places, you've taken all the plot points, which are used to draw the canal overlay, as well. But somehow you've managed to miss all the bridges, including swing and lift There are also requirements about data accreditation when using OpenStreet Map and Maplibre, You seem to be ignoring those. @Richard Fairhurst And.... really? I also find it extremely concerning that Wyre Lock claims Lock 15 and Lock 16 are close by but are actually on the Peak Forest when you follow the links. Diglis Locks are not 12.8 km away - they might be in a straight line I'm just going to give up....

That's good to know - were closed last time we went through

The CRT ones or the Boatyard ones?

Or Bobs is a thing. In quilting they have things called Fat Quarters. So maybe these are fat Bobs rather than thin Bobs
