NATO summit in Strasbourg/France

[zki.dlr.de] On April 4 2009, the leaders of the 26 NATO
countries met in Kehl and Strasbourg. Extensive security measures were
being implemented in both cities.

In the course of the ARGOS project, satellite images of both cities on
that day were taken to provide examples for the possibilities and
limitations of satellitebased analyses of large-scale events.
