[OSM-talk] [HOT] Fw: Disaster Preparedness Project

[Joseph Reeves]

OT, I know, but I would love to see the same thing available as Kindle
friendly pdf (or native ebook format) download. I recently drove
around France for a weekend wishing that my atlas was Open, offline
and on my ebook reader.

Cheers, Joseph
