Satellite Earth observation is becoming more and more an efficient tool for monitoring all kinds of resources of Earth. Remotely sensed data are now a reliable basis for decision-making in many areas of society. We experience increasing resolutions both spatially and spectrally. Constellations of small satellites are capable to provide good daily coverage of the Earth's surface and allow to increase the temporal resolution. The progress resulting from satellite Earth observation allows to expand the application fields but also brings to light new problems to be discussed in a broader public debate. This Conference deals with two important and topical aspects of satellite Earth observation:> treaty monitoring and law enforcement through satellite Earth observation,> privacy conflicts from high resolution imagery. It brings together experts from the remote sensing and in the legal fields. It i.a. aims at decision-makers in the field of treaty monitoring and international law enforcement (foreign and environment ministries, international organizations). This provides the unique opportunity to discuss the different implications stemming from the technology developments and applications as well as from legal and regulatory perspectives. The focus of the discussions at this Conference is to optimise the regulatory framework for satellite Earth observation thus supporting the full implementation of its potentials.
