2007 California Department of Water Resources Topographic LiDAR: San Joaquin Delta
This kmz file shows the extent of coverage for the 2007 CWDR San Joaquin Delta lidar data set.
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.

|Purpose:||High-resolution digital elevation maps generated by airborne and stationary LiDAR have led to significant advances in geomorphology, the branch of geoscience concerned with the origin and evolution of Earth's surface topography. LiDAR provides unique characteristics relative to other remotely sensed data sources by providing three-dimensional feature information that cannot be derived from traditional imaging sensors.|
