Laser Scanning Used to Calibrate SAR Satellites

Researchers from the University of Miami, Florida International University and UNAVCO recently reported that they had used terrestrial laser scanning (TLS) in the Florida Everglades National Park to calibrate remote sensing SAR (Synthetic Aperture Radar) satellites.

TLS measurements were used to construct the vegetation structure and above ground biomass in 4 disparate vegetation communities. These same study sites were then analyzed using the satellite imagery and a comparison made to calibrate the remote sensing procedure. If this procedure can be trusted the SAR satellites can then be used on a regional scale to more cost effectively manage larger regions.
