USA, 7 February 2007 – EarthData has signed a $1 million contract with URS Corporation for aerial lidar surveys over the Sacramento-San Joaquin River Delta. Covering 1,600 square miles, the project calls for 1-meter post-spacing lidar data, hydrographic breaklines, and 1′ contours. California’s Department of Water Resources (DWR) will use these datasets to evaluate levee stability under various flooding scenarios as part of its Delta Risk Management Strategy.
“The aging levees in the Sacramento-San Joaquin River Delta have a hefty responsibility,” said URS Project Manager, Syd Bowcott. “Not only do they ensure water supply and water quality for the state, the levees safeguard 700,000 acres of land and millions of residents from the threat of flooding.”
Key infrastructure like highways, railways, and pipelines also depend on levee stability. The detailed lidar elevation data from this project will help DWR identify areas where levees need repair, as well as areas requiring additional levee structures to protect recent urban developments.
Aerial data acquisition for the Sacramento-San Joaquin River Delta project now is underway. Final datasets will be delivered to URS for independent evaluation by August 1, 2007. Other team members on the project include Airborne 1 Corporation and Towill, Inc.
