From Kent's Imperative:

We continue to be impressed with the uses for commercial overhead imagery which the private sector now increasingly relies upon in an astounding array of situations. While none of these applications are new from the perspective of an intelligence community which has been employing national technical means to similar ends for decades, their independent re-discovery in the outside world, and operationalization in support of crisis situations, remains fascinating from the perspective of intelligence studies scholarship.

The most recent example comes from the conflict in Chad - which provides an excellent and evolving unclassified teaching case to explore the issues involved in small wars and destabilizing countries, particularly for the unique kinds of intelligence support required in noncombatant evacuation operations and other stability and support missions. UNOSAT has recently released a series of products derived from commercial satellite data which attempt to estimate the scale of urban evacuation of the capital of N´Djamena.
