UNOSAT is part of a group of specialized players including DLR of Germany, the Asian Institute of Technology in Bangkok, and others. The group is working under the coordination of the Japanese authorities and JAXA to bring to value the data generated by the Space Charter and provide Japanese authorities with actionable information. In addition, thanks to a specific arrangement between UNOSAT, the French Space Agency CNES and the firm ASTRIUM GEO-Information Services, UNOSAT has released to OpenStreetMap a set of images which volunteers around the world can now use to produce information hopefully useful to rescuers on the ground in the affected areas. Licensing limitations on commercial imagery make it difficult to share publicly some satellite imagery for the use by crowd sourcing circles, UNOSAT has been working to ease these restrictions while respecting copy right and legal clauses, hoping that a trend will emerge soon to give more breath to valuable initiatives made possible by today's information technology and internet resources.
