Airborne Laser Scanning for calibration and validation of inshore satellite altimetry: A proof of concept
2017
Remote Sensing of Environment
Preserved Fulltext
Here, we show a proof of concept by comparing airborne LIDAR heights over Lake Balaton, Hungary with near-concurrent Envisat and Jason-2 altimeter heights and water level gauge data. ...
Results show standard deviation of heights is in the order of millimeters for LIDAR and 40-50cm for altimetry and bias with respect to gauge heights is 5cm for LIDAR compared to 40cm for altimetry. ...
Acknowledgments Airborne LIDAR data used for this study was collected in the framework of the EUFAR project under contract number 2271, by the NERC Airborne Research and Survey Facility. ...
