Description: This shapefile represents the water's edge breaklines used to control the extent of refracted green laser returns. These lines were also used to classify water within the .las point cloud. Water boundary polygons were developed using an automated algorithm which weights LiDAR-derived slopes, intensities, and return densities to detect the water's edge, and then manually edited as needed. The horizontal datum for this dataset is NAD83 (2011), the vertical datum is NAVD88, Geoid 12B, and the data is projected in UTM Zone 10N. Units are in Meters. Quantum Spatial collected the Lake Tahoe LiDAR data for Spatial Informatics Group between 09/09/18 and 09/16/18.
