Hi, Andrew:
I can start tomorrow early in the morning (it's now midnight in the
Philippines and I am going to sleep).
Could you produce that osm file with the residential polygons (only
those that have names of course)? Better if you split them in three
files, one for each country, so it's easier to process them. I am in a
tiny island using 3G, so I could run out of data easily. The files,
you can upload them to dropbox or something similar. With luck, I
could maybe have the result file during the morning, but never promise
anything.
About the pgp, I guess I have to update my system...
Cheers,
Rafael.
