Lidar measurement of snow depth: a review
Laser altimetry (lidar) is a remote-sensing technology that holds tremendous promise for mapping snow depth in snow hydrology and avalanche applications. Recently lidar has seen a dramatic widening of applications in the natural sciences, resulting in technological improvements and an increase in the availability of both airborne and ground-based sensors. Modern sensors allow mapping of vegetat...
متن کاملLidar Measurement of Snow Depth: Accuracy and Error Sources
Airborne laser altimetry (lidar) is a remote sensing technology that holds tremendous promise for mapping snow depth in snow hydrology and avalanche applications. In recent years lidar has seen a dramatic widening of applications in the natural sciences, resulting in technological improvements and an increase in the availability of sensors. Modern sensors allow recording of multiple pulse retur...
متن کاملPolarization lidar for shallow water depth measurement.
A bathymetric, polarization lidar system transmitting at 532 nm and using a single photomultiplier tube is employed for applications of shallow water depth measurement. The technique exploits polarization attributes of the probed water body to isolate surface and floor returns, enabling constant fraction detection schemes to determine depth. The minimum resolvable water depth is no longer dicta...

متن کاملIndependent Evaluation of the SNODAS Snow Depth Product Using Regional Scale Lidar-Derived Measurements
Repeated Light Detection and Ranging (LiDAR) surveys are quickly becoming the de facto method for measuring spatial variability of montane snowpacks at high resolution. This study examines the potential of a 750 km LiDAR-derived dataset of snow depths, collected during the 2007 northern Colorado Cold Lands Processes Experi5 ment (CLPX-2), as a validation source for an operational hydrologic sno...
