Is this coastcheck process a documented workflow?

Are these available for download somewhere or would I need to extract them
from a planetfile?

[OSM-dev] processed_p.tar.bz2 inverted?

2012-02-22 Thread Sven Geggus
Hello,

this is probably more of a GIS Question than an OSM one.

For a nice combination of hillshade and water I would like to invert
the processed_p.shp file from http://tile.openstreetmap.org/processed_p.tar.bz2

This should prevent rendering of hillshaded water on the edges as
water can be rendered above hillshades this way.

Unfortunately this does not seem to be as easy as it sounds.

I tried to import it into postgis and using ST_Difference but it
looks like processed_p.shp is somewhat broken.

Any other hint ob how this could be done?

processed_p is closed shapes on a 100 mercator km x 100 mercator km grid, not 
one continuous area. There is also some overlap to prevent antialiasing issues.

You might be able to generate an inverted one by inverting the coastline_*.shp 
files before passing them to the rest of the coastcheck process to generate 
processed_p.
