RTK Ground Check Points for 2016 King County/Puget Sound Lidar Consortium Lidar Project

RTK ground check points are used to assess the vertical accuracy of the LiDAR data. Data was processed in reference to NAD83 (CORS96), however the horizontal datum for this dataset is defined as NAD83 (HARN) as the difference is generally small and allows for greater ease of use with data in different datums. The vertical datum is NAVD88, Geoid 03, and the data is projected in Washington State Plane North. Units are in US Survey Feet. Quantum Spatial collected the Lidar data from 02/24/16 through 5/25/2017.
