Thinking forward to the Isle of Wight workshop, but also relevant elsewhere,
is the issue of coastlines.
Two issues spring to mind.
Firstly is it necessary to have coastline data in OSM?
Secondly if the answer to the first question is yes, then how should the
coastline data get into OSM? It will not always be possible to walk / drive
along a coastline either because the land may be private, or because it may
be inaccessible due to woodland, cliffs etc. It obviously would be possible
to use the Landsat imagery and trace the coastline for an area that was
being mapped, but if the orthorectification of the Landsat imagery is not
accurate then this is not ideal. Also it breaks the idea of having all OSM
data derived from user entered GPS data.
