[OSM-talk] New mapping satellite

[Kevin Bullock]

I am submitting an abstract to present WorldView-3 capabilities at SOTM in
Nov. This is the third "WorldView class" satellite and its predecessors
both achieve better than 3.5m CE90 (circular error, 90th percentile), and
have since 2007 and 2009 when they were launched. WorldView-3 is expected
to have similar accuracy. DigitalGlobe uses the entire constellation of 6
satellites to map the world. True there are many "task orders" we fulfill
but the larger mission is to map the world. We can generally do this on an
annual basis.

With our partnership with Mapbox, the OSM community will start seeing this
imagery through the Mapbox satellite layer; this will be of huge value for
mapping new areas and updating OSM.

Here are a couple videos from our launch yesterday:

and my own personal video recorded from Lompoc, CA
