In October 2014, OpenTopography released lidar point cloud data and limited raster layers (bare earth, highest hit, intensity) for Sonoma County, CA. This week, new raster layers were added to the Sonoma County raster data in the OpenTopography portal. All raster layers now include: bare earth, hydro-flattened bare earth, highest hit, canopy density, and vegetation height as well as intensity layers for all returns, and vegetation.
