Re: [Talk-ca] Missing harbours and marshes - L Ontario
The marshes aren't actually deleted - they just don't appear on the OSM map. I have verified that the Canvec data that defined the shoreline and the connected marshes still exists. It just doesn't show because the natural=water ways are not currently closed. So once the cleanup work is complete, all should be well.

[Talk-ca] Missing harbours and marshes - L Ontario
I just noticed that several small bodies of water along the north shore of Lake Ontario have disappeared (partially or completely). Some harbours affected are Oshawa, Bowmanville, Newcastle, Port Hope, and Cobourg. Some marshes (e.g. Westside Marsh near Bowmanville) are gone. Some creek/river sections near the shore are gone as well. Can someone clarify what is happening with this?

Re: [Talk-ca] Missing harbours and marshes - L Ontario
You're right, the harbour is there. But not all of it. The large creek to the west and the small creek to the north flow into the harbour and were previously shown correctly on the map. Now they appear to abruptly end before reaching the harbour. Same pattern for the Bowmanville harbour. And I think the same for Newcastle, Port Hope and Cobourg.

Re: [Talk-ca] Missing harbours and marshes - L Ontario
The Cycle Map and Osmarender views in OSM show older views of the affected areas (prior to change).

As the US edge of the Great Lakes are tagged as natural=coastline I believe that all the Great Lakes should be tagged this way. There are a few reasons for this: 1. it makes the lakes consistent as it only leads to confusion if the US side is defined one way and the Canadian side is defined another. Luckily, the renderer has hacks to deal with this sort of thing so it currently works. 2. Large multipolygons can be very difficult to modify. Imagine if there are changes to the coastline (especially when lots of islands) due to updated data and the new multipolygons from canvec don't have the same borders. Nightmare. Lake Huron has already been converted to using the canvec data and only uses coastlines. I am about 2/3 of the way done with converting Lake Erie(*). If no one else is working on Lake Ontario, I will start that when I'm done with Lake Erie. (*) It is very fast as there are few islands. I spend 8 times longer making fixes to the roads uncovered by the validator than I do on the coastline. On the other hand Lake Huron had 1 islands and took over a month. -- James (Jay) Treacy tre...@debian.org ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

Re: [Talk-ca] Missing harbours and marshes - L Ontario
Will you be continuing? I've been on a roll and would be willing to continue into Lake Ontario, but as you've started it is only fair to let you continue if you wish. If you wish to continue, I'll just work on another area. There is a tricky part between Lake Huron and Lake Erie that I've been avoiding. Yes, I will finish the north side of Lake Ontario (the part I have been trying to clean up). ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
