Mission

Active sensor-based SAR and LiDAR technology, introduced in the late 90s, has received wide acceptance in airborne surveying as a leading tool for obtaining high-quality surface data in an unprecedentedly short turnaround time. The adoption of the new technology was fairly smooth and quick, primarily due to the high-level of automation of the data processing. LiDAR systems nowadays do range measurement with an increasing number of points per surface, count multiple returns per single shot, deliver reflectance values of the illuminated surface and capture the full waveform of the backscattered laser light. The role and capabilities of Interferometric SAR (InSAR or IFSAR) continue to expand, particularly with respect to wide area DEM creation. Areas of significant technical interest and application include Polarimetric InSAR and Differential InSAR with respect to quite different but important applications. Fusion of high resolution SAR images with optical is again of interest as new techniques are applied. The mission of this working group is to address data processing and interpretation issues to strengthen the role of active remote sensing systems in mapping and monitoring applications. Additionally, the integration of active remote sensing data with other imaging systems is promoted. The objectives of this working group are detailed in the Terms of Reference.
