Contours derived from the 2016 LAR-IAC4 program. The Digital Elevation 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 makes it extremely accurate. This source was used for urban/suburban areas of the County in mainland (approximately 4,107 square miles) and Catalina Island covering approximately 107 square miles, while for the National Forest contours were created using stereo compilation.<\/SPAN><\/P>

This dataset meets or exceeds ASPRS (American Society for Photogrammetry and Remote Sensing) 1:100 scale mapping. Accuracy is within +/- 2 feet of true location with 95% confidence.<\/SPAN><\/P>
