ESA Data Access Policy Draws Mixed Reviews

摘要

Europe's emerging policy of offering free and open access to almost all data from the European Space Agency (ESA) and European Union Sentinel Earth observation satellites won praise from U.S. government officials and from prospective users of the satellites' diverse data sets.rnOwners of satellite systems that were all or partly funded by the private sector, and whose business models are based on imagery sales, have other ideas.rnFor these companies, the new policy, disclosed by ESA and European Commission officials during the Living Planet Symposium held June 28 to July 2 in Bergen, Norway, poses threats as well as opportunities.
