[OSM-talk] IoW coastlines

[David Groom]

I've just walked about 1.5km of coastline in Bembridge, and uploaded the GPS 
tracks to the server.

A comparison with the PGS data confirms what I had already thought, in that 
in general the PGS data is a little to the south of where it should be.

Screenshot from JOSM is now on page
