repository or emergency open data

If it's true that some datasets in the emergency management/humanitarian
domains  are becoming available
then  could it be good practice to start an index of sorts?

if there is enough materials, and/or ideas,
and someone wants to lead
then
an opportunity see the call

I can support but not lead
