Well Landsat's resolution is low so any coastline traced using Landsat
(like almost all of the coastline corrections 3 years ago) will have a low
average distance between nodes marking it as low to average quality. So
while the offset may be a problem, I think the low node density can be
already us
Interesting. Thanks for sharing Eugene.
I think the common issue for the Philippines is the third case in the
first image ("coastline with detailed but inaccurate approximation").
When we started the coastline correction 3 years ago, there was very
little hi-res imagery. For my part, I did most
Hi guys,
Here's a nice analysis done by Christoph Hormann in automated assessment of
the quality of OSM's coastline data:

If you don't want to read the whole article, here's the TL;DR version:
Coastlines where there are a few nodes per kilometer
