I've retraced significant chunks of the coastline around Hood's Canal
and the Olympic Peninsula from higher-resolution imagery and occasional
local knowledge (inlets, flats, rocks, spits). I'm all in favor of
importing higher quality coastline, since PGS is fairly coarse, but I
hope that it is done in a way that doesn't destroy other work that's
been done.
