There's a large chunk of bad coastline around The Philippines that's been there since some shapefile update in the recent past... It can be seen here... http://www.openstreetmap.org/?lat=15.481&lon=120.274&zoom=9&layers=B000FTFT The coastline is all OK now (there were a couple of problems at one point) and the view at the coastline checker ( http://tile.openstreetmap.nl/coastlines.html?lat=15.481&lon=120.274&zoom=9) and a local mapnik render I've done using the coastline checker output both show the coastline correctly... A trac ticket was raised about this problem a couple of days ago now, but, I'd have expected an update of the shapefiles to have corrected this... It looks like it's only corrected the problem above zoom level 10 though suggesting that only the processed_p shapefiles have been updated... So... some questions... Is there a problem with the world boundaries shapefiles being used? Were they generated from the processed_p shapefiles at some point? Are the world boundaries files used on tile different to the ones packaged here http://tile.openstreetmap.org/world_boundaries-spherical.tgz? What would be involved in regenerating them? Once regenerated, could new ones be made available somewhere? Thanks, d
