[OSM-talk] How to improve coastline fixing?

[Frederik Ramm]

Hi,

   I see that we're beginning to get real nice coastlines. Significant
work has been done for Denmark, the Netherlands, Germany, France and
portions of the UK. (Of course most of the coastline was already there
from imports, but now people seem to start taking an interest.)

I have done a bit of work in the Scottish Isles and I must say it is
quite tedious. 

First I look at the zoomed-out slippy map and find places that don't
look right. Zooming in, I see that some have been fixed at level 12
and are just missing lowzoom; others are still defective at level 12.
I fire up JOSM and load an area (using my recntly mentioned JOSM
version where I can enter tile numbers to designate the bounding box),
sometimes only to find that the area has been fixed and just needs
re-rendering on level 12. Other times it hasn't been fixed and I can
repair it. 

(And this doesn't even mention cases where bugs stem from the ocean
tile index file.)

How are other coastline workers doing it, and how could we improve the
process?

I have been thinking about some sort of "double plugin", for Firefox
and JOSM, where I could right-click on the slippy map to load an area 
into JOSM. Or maybe do more work on the slippymap plugin for JOSM, 
so that a proper slippymap background becomes possible in JOSM? 
(Currently, only level-12 tiles can be loaded, and they have to be 
loaded individually, and JOSM gets very slow very quickly if you 
load many.)

Other ideas?

Bye
Frederik
