Service Description: This data set was collected and produced by Towill, Inc. under contract with to the California Department of Water Resources (DWR). Data are considered public domain.
Field Survey Operations
Field Equipment
Ground control for the aerial imagery was supplied through onboard ABGPS systems and tied to numerous CORS stations operating near the study area.
Horizontal and Vertical Control Surveys
Primary Control
Survey Control is based on ABGPS and CORS stations. Please see Survey Report dated January 18, 2019 for information regarding specific CORS stations used for georeferencing the orthophotography.
Horizontal Coordinate Datum
The horizontal datum is the National Geodetic Survey (NGS) Continuous Operating Reference Station (CORS) North American Datum of 1983 (NAD 83) California Coordinate System (CCS83) Epoch 2010.0 (2011 realization), Zone 2, US Survey Feet.
Vertical Datum Elevations established in this survey are North American Vertical Datum of 1988 (NAVD88).
Airborne LiDAR
The airborne LiDAR mission was performed over a two-day period; September 13-14, 2018. The sensor used to collect the data is a Teladyne/Optech Orion 300 and the laser was set to emit 8 points per square meter (8 PPM^2). The LiDAR strips were processed and calibrated using Optech’s LMS software suite and data from the CORS stations identified in the Survey Report dated January 18, 2019. The LiDAR dataset was classified to separate ground from non-ground features using the following classes:
Class 2 = Ground
Class 8 = Key point
Class 9 = Water
Additionally, hydro-break-lines were digitized from intensity images and used to separate ground from large water features (streams wider than 100 feet and ponds larger than twenty five acres). The derived bare-earth surfaces were formatted in both TIN and DEM formats.
