Hi all. Could (or should) some local OSM people/editors do something with these lakes: Winnipeg, Superior, Erie, Ontario, Lakes/Coastline slightly South-West from Montreal, Ladoga and Onega. Namely, these huge lakes are repeated and fully, or partly overlap the corresponding holes (water/sea areas) in the Planet-land. Consequently, there are many, many errors in the related maps. Besides, this situation generates a huge redundancy in vector mappings. To illustrate the issue look at the permalink:
from today's Slippymap. If you now separately display the latest OSM lakes (natural=water/water=lake) dataset and the coastline dataset you will find hundreds of details disappearing from lakes and/or from coastline dataset. Finally, note that a simple retagging/moving these data from lakes to coastline (or the contrary) never helps.

Sorry, please ask somewhere else - that is not a "question" relevant to this help site. See There are even local forums and mailing lists.

By the way: aside from a very confusing street layout (I first thought I would see tile borders) and apparently partial mapping of streets and forests I see nothing special there ...
