Final Report

Workshop Overview:

The objective of this study is to imagine remote sensing systems and processing techniques that will produce observations (Optical, SAR, or Lidar) with optimal spatial and temporal coverage, ground resolution and registration accuracy to measure deformation and surface changes that are relevant to investigate the internal and external dynamics of Earth and potentially other planets. We will evaluate the technical challenges and explore possible solutions to achieve these goals both at the level of the sensor and of the data processing. Indeed, our experience using data from existing systems shows that simple modifications of currently used technologies could lead to major improvement of the registration quality, for example with appropriate distribution of the CCDs in the focal plane of an optical system. Exploitation of new spaceborne digital hardware capabilities is also driving innovation in radar designs, redefining what is possible for future missions in terms of coverage and accuracy.

As a result, there is a broad range of ways this study will impact future missions. We could come up with specifications for dedicated systems and better way of integrating and exploiting a wide range of data from future Earth Observing missions.
