[OSM-talk] Coastlines

[Steve Chilton]

Data quality looks quite reasonable on this sample. I have made SVG
(saved as PNG) of the mainland bit of the example below.
See:
http://wiki.openstreetmap.org/index.php/WikiProject_Isle_of_Man#Assistan
ce
There are two roads that go in the sea (1 in Port Erin and 1 in Port St
Mary) but local gps work and editing could cure that. On balance I would
say "better in than out" (ie if upload has worked for whole of island
then repeat in stages for other areas). Is projection an issue over
larger areas?
NB: renderer (osmarender2) doesn't recognise all of linework as some is
still in class= rather than highway= format.
Maybe worthwhile to also check in a more (data) populated area. Has
Douglas been mapped in detail? Maybe I'll have a look at that when I
have time.

Cheers

Isle of Man coastline from PGS is complete (uploaded to OSM) and might
be 
useful as a test area for evaluating both the data-source and the upload

tool.
