Re: [Ecrit] Comments for draft-sun-ecrit-unsafe-areas-00

Hi,

I also read the draft, and like Hannes, my first thought was about a
separate service URN for this propose.

One additional comment:
When the unsafe-Information is included to the Mapping Information of
a particular PSAP, there could be a problem when a PSAP is responsible
for a large area. Assuming a police PSAP is responsible for a whole
federal state, there may be hundreds of unsafe areas inside - and most
of them will be far away from my current location. So it could be more
interesting to query for all unsafe-areas within a radius of 5 km,
regardless of the service boundary of a particular PSAP.

cheers
