[OSM-talk] How to fix wonky coastline?

[Steve Bromwich]

Thanks, David. It looks like the problem might be where I split up the 
coastline into multiple ways, as when I bounce between the viewer and JOSM 
the point where it goes haywire is the node connecting the two ways (eg, 
http://www.openstreetmap.org/index.html?lat=44.61701416474894&lon=-63.50838186135787&zoom=14 
and 
http://www.openstreetmap.org/index.html?lat=44.61710580833693&lon=-63.56550217216712&zoom=15); 
if I make an area to "block off" areas of sea, do you (or anyone else) 
know if that would cause a problem? I think perhaps making an area between 
the bridges and the mouth of the harbour, and then the bridges and the bay 
might do it, but I can't find any obvious guidelines on the wiki.

Cheers, Steve
