Radar-lidar article published

My coauthors Amy Frazier (Arizona State University), Son Nghiem and Gregory Neumann (NASA JPL, Caltech), Yun Zhao (University of Illinois at Springfield) and I published an article entitled "Satellite scatterometer estimation of urban built-up volume: validation with airborne lidar data" in the International Journal of Applied Earth Observation and Geoinformation. This is an especially exciting contribution to the land use/land cover (LULC) remote sensing literature because it confirms that satellite-based radar data (from QuikSCAT in this case) strongly correlate with airborne lidar-derived calculations of built-up volume across a variety of urban environments. This is a breakthrough correlation that supports use of spaceborne radar data (which are much more readily available compared to other datasets; i.e. lidar, etc.) to evaluate 3D LULC change globally. Given that most analyses are conducted in two-dimensions using remotely sensed imagery, this provides a new approach for a more comprehensive assessment. The work was also recently presented as a poster at the AGU Fall Meeting in Washington, DC.
