Fortunately this should be fixed in the most part by this weekend. I've 
filled in several thousand kilometers of coastline in northern Canada in 
the past couple days, and have a couple hundred kilometers of gaps left 
to fill that are the biggest problems on the mainland, likely these will 
be done tonight and uploaded tomorrow. Some of the larger islands exist 
in part, and gaps in data such as those I've been correcting using the 
lakewalker plugin with a small modification to use the Landsat IR3 
instead of IR1 imagery.

If anyone else wants to help cleaning up parts that have small gaps or 
backwards ways, especially around Alaska and BC, it would be much 
appreciated.
