Using tripod mounted LiDAR, imagery scans of targeted areas of snow covered terrain were collected at various intervals during Winter 2008 both at the main study site of the Central Sierra Snow Laboratory and at a State of California snow course on Donner Summit, California. LiDAR's high measurement accuracy in both range and position facilitates the generation of very detailed three-dimensional data sets that were then analyzed for snow volume over the targeted area. Repeated scans of targeted areas were used to calculate changes in snow depth and volume. Snow depth values as measured by the LiDAR scanner correlated well (R2 = 0.96) with coincident hand measured values.
