Updated Tahoe Data Products

Sep 14, 2011

A revised set of data products for the Lake Tahoe Basin lidar dataset are now available via OpenTopography. This updated release addresses specific issues related to lake level elevation in the hyro-enforced bare earth surface model. Specifically, the data vendor, Watershed Sciences, reprocessed the hydro-enforced surface so that "all lakes were lowered to the lowest identified shoreline elevation to ensure a constant elevation equal to the shoreline elevation.
