Thematic mapping from sensor formations

Based on the expectation that remote sensing in the future is likely to be served by large swarms or formations of smaller, simpler platforms and sensors than at present, it is suggested that thematic mapping under that scenario is most likely to be based on decision level fusion methods. Individual platforms are likely to include a degree of on-board processing or intelligence to permit both neighbourhood and global decision making. That will provide redundancy against platform failure and the ability to reconfigure imaging strategies adaptively. Candidate fusion techniques are reviewed.
