  • In August of 2019, Quantum Spatial was contracted by Seattle Public Utilities (SPU) to collect topobathymetric Light Detection and Ranging (lidar) data in the fall of 2019 for the Chester Morse Reservoir site in Washington. Traditional near-infrared (NIR) lidar was fully integrated with green wavelength return data (bathymetric) lidar and multi-beam sonar (collected by Northwest Hydro), in order to provide a seamless topobathymetric dataset. Data were collected to help to better characterize the topography and bathymetry of Chester Morse Lake, Masonry Pool, and the deltas of the Cedar and Rex Rivers in the Cedar River Municipal Watershed. This report accompanies the final integrated lidar and sonar dataset and documents contract specifications, data acquisition procedures, processing methods, and analysis of the final dataset including lidar accuracy and density.
