|2007 California Department of Water Resources Topographic LiDAR: San Joaquin Delta
||These data are from LIDAR flights of the Sacramento-San Joaquin Delta conducted during
late January and February of 2007. The work was conducted under contract issued by
California Department of Water Resources to URS Corporation. The prime LIDAR creation
subcontractor was EarthData International, (later Fugro EarthData), also known as
EDI. The principal aerial survey firm under subcontract to EDI was Airborne 1 Corporation.
In effect, Airborne 1 performed the aerial survey, and EDI did the processing and
deliverables preparation. Also involved in the contract to URS was an independent
QA/QC firm, Spectrum Mapping LLC. The data was delivered to CSC as unclassified, multiple
return elevation measurements and intensity in LAS V1.0 format. The NOAA CSC used
an unsupervised classification algorithm to classify the data into the following ASPRS
classifications: Class 1 (Unclassified), Class 2 (Ground), and Class 7 (Noise) . Class
2 includes bare earth points and water points.
