ICESat Full-Waveform Altimetry Compared to Airborne Laser Scanning Altimetry Over The Netherlands
Since 2003, the full-waveform laser altimetry system onboard NASA's Ice, Cloud and land Elevation Satellite (ICESat) has acquired a worldwide elevation database. ICESat data are widely applied for change detection of ice sheet mass balance, forest structure estimation, and digital terrain model...
