[HOT] imagery date

[Andrew McKenna]

Hi all--

Depending on the nature of the task and mapping project, we may be able to
provide DigitalGlobe imagery for the OSM community through the US
Department of State's MapGive initiative, which provides DG imagery to OSM
projects through the NextView license. This is especially true if the
project has a humanitarian component in NE Nigeria.

Who setup these tasks?

Cheers,
Andrew
