Hey, I finally found the diary thing here! Maybe I'll start using this instead of tracking progress on my user wiki page...

After a few weeks' absence, I'm back, and working on large-scale stuff (lakes provincial highways) instead of urban street mapping. Back in June, I wrote a little tool to trace lakes from Landsat data which does a great job, and tonight I used data it generated to correct morwen's coastline import of Lake Manitoba and my earlier hand-tracing of Lake Winnipeg. It was way, way better than my hand trace, and mostly-but-not-always better than the coastline import, so I'm pretty pleased. I'll have to try to get svn access so I can get this tool in there for other people to play with.
