Hi Folks
I'm new to mapping, and looking at the newbie list archives I could not
see anything that addressed my question, so here I jump into the mainstream.
I recently spent some time on a small island in the Mediterranean. As
the area was not well covered in Openstreetmap, I took GPS traces

So what's going on here? Are the coastline traces somehow displaced,
and if so, how can this be corrected ?
Coastline traces are often inaccurate, and often displaced. The best
option is to adjust them manually. At least in JOSM I can

And remember the coastline should show the mid-tide level.
No, it should show the high-tide level. Most coastline data in OSM is based on
PGS data, which shows the high-tide level.

It's a good job you pointed that out, I've always been led to

it was mid-tide level and am going to do some tweaking of some
coastlines soon. I'm sure there's either a wiki page or a list

suggesting it should be mid-tide somewhere.
We should really have both a high tide and a

There are large parts of tropical coastlines where the coast is marked
as the outside edge of mangrove swamps. These are covered with water
most of the time, and adjacent to the sea, so are below the high
tide line, but are considered to be part of the land. You can't take
a boat through them,
Hi All
Thanks for the replies, I re-examined my tracks, existing roads and the
Yahoo layer - if only we had an extra zoom level or two it would be more
obvious ...
The island in question is Menorca.
The road that I travelled every day, due to a one way traffic system, is
along the edge of an
