2006 2-foot contours – LAR-IAC

2 foot contours acquired as part of the Los Angeles Regional Imagery Acquisition Consortium in 2006.

The Digital Surface Model was acquired using LIDAR (Light Detection And Ranging), which used a laser mounted in planes that were acquiring 4-inch orthophotography data. Hundreds of millions of ground measurements were made using this system, which […]
