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

Jean-Guilhem,
It sounds like there could be a lot of demand for the ability to generate
these map booklets.
*Thomas* - are there any updates on this effort from the MapOSMatic side of
things?
 I am working with a group of designers on the disaster prepardness project
so we can definitely contribute design resources.
