Description: 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.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.Detailed product information is contained in the LAR-IAC Product Guide.We highly recommend that you visit the LAR-IAC Project Website to find a rich source of information about the data and the LAR-IAC program. The site includes project documents, full FGDC compliant metadata, data downloads of related GIS used to complete the project, sub-licensing information, sample imagery and data, and information about the 2014-2016 acquisition.GIS Data showing flight-date information is available from the LAR-IAC Project website site, and elsewhere in the LA County GIS Data Portal.The imagery is held under license from Pictometry International Corp, and cannot be publicly released. Government entities are eligible to join the LAR-IAC program to access the data. Private entities may contact Pictometry directly to purchase selected parts of the data.
