A cry of frustration:

I do bimonthly runs of the worldwide coastlines (http://metro.teczno.com/#coastline), and Canada seems to be a recurring source of problems. What the heck is going on up there? I consistently see new imports of what seems to be Canvec data screwing up coastlines and making for some deeply broken renders:


Most of that junk in the Atlantic Ocean is newly introduced within the last few weeks, and is making it difficult to get out a clean coastline suitable for rendering. It shows up in the main OSM mapnik tiles in Hudson Bay, too:


I've been trying to fix problems as I encounter them and I've managed to fix invalid coastilnes around Baltimore, Houston, Tampa and the dreaded Montréal area in an effort to generate a usable map of North America, but this Canvec stuff is absolutely killing me.
