Actually, speaking of coastlines, have a look here:


I've verified the route of the coast road with my own GPS, and it's
accurate. Any ideas on an approach to cleaning up the coastline?

Also, I have traced some rail lines from overhead imagery, but it seems
the imagery is slightly off. I'll hold off tracing any more until I can
get a GPS fix, or else an accurate sense of how much and in what
direction the imagery is off. Unfortunately the Yahoo imagery isn't very
detailed in Mayo...
