Lidar dataset collected for the five kilometer zone around the entire shoreline of the Salton Sea. Data obtained in November 2010, at around annual lake minimum level. Target lidar point density was 5 points per square meter and targeted vertical accuracy was /- 9.25 cm. Data were delivered in 1,500 meter by 1,500 meter tiles. Deliverables included a bare earth digital elevation model with a one meter cell, raw swath LAS files, classified LAS files, metadata, and ancillary data including survey reports. All data are in the public domain.
