Hi Stéphane,

I would concur with Kate that within the OSM DB doesn't seem like the
best place to store it, but rather a place where it can be overlaid
with the OSM DB.

I'd be really interested to see if Sahana would make a good place to
store this data: http://eden.sahanafoundation.org
We don't currently include Hazard data models, but rather just overlay
sources from elsewhere (typically WMS), but we would be very
interested in actually having these within the Sahana database.
I know that the Red Cross are interested in adding this to their
Sahana deployment.

Thoughts on this approach welcomed :)

Best Wishes,
