Hi Pierre:

I am merging all the impassable roads info provided by the US NGA. I am
almost finished.

I am using only status=impassable + typhoon:damage=yes tags that we have
in the workflow of job 350 of the task manager, plus "source=NGA Damage
assessment report-11/17/2013" as suggested by Bruno Remy, in order not
to have any inconsistency with the rest of jobs.

Cheers,

Rafael.
