{ "currentVersion": 11.3, "serviceDescription": "This is a mosaic of the hydro-flattened digital elevation model (DEM) surfaces of the San Francisco Bay and Sacramento San Joaquin Delta. This only includes the section of the acquisition that corresponds to California State Plane Zone 2. \n\nThis LiDAR was collected by NV5 & Guida through a DWR contract and partnership with\nDelta Stewardship Council (DSC), Delta Conservancy, and San Francisco Estuary Institute\n(SFEI). The overall work unit area covered approximately 1,988 square miles over California\nat Quality Level 1 LiDAR according to USGS 3DEP standards.
