2014 Color Orthophotography – LARIAC 4

***NOTE***The 4-inch imagery is  under license from Pictometry International, and cannot be publicly released.

This dataset represents natural color, leaf-off, 0.33-foot (4-inch) high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LARIAC) in winter 2013/2014.  This imagery covers the majority of urban/suburban areas of the County in mainland (approximately 2,898 square miles) and Catalina Island covering approximately 75 square miles.

The rest of the County, covering the National Forest, is covered by a one foot (1-foot) resolution digital orthoimagery, approximately 1,056 square miles, and is a separate dataset.

This dataset meets or exceeds ASPRS (American Society for Photogrammetry and Remote Sensing) 1:100 scale mapping.  Horizontal accuracy is 1.25 feet (16 inches) with 95% confidence.

Detailed product information and related Documents and Data are available at the LARIAC4 Documents and Data Page.

LARIAC Program

We highly recommend that you visit the LARIAC Program Website to find a rich source of information about the data and the LARIAC 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 2006 acquisition.

GIS Data showing flight-date information is available on the LARIAC site and elsewhere in the LA County GIS Data Portal.

The 4-inch imagery is  under license from Pictometry International, and cannot be publicly released.  Government entities are eligible to join the LARIAC Program to access the data, and their contractors are able to access .  Private entities may contact Pictometry directly to purchase selected parts of the data.

Public Domain version

A 1-foot, resampled version of this file is available from the US Geological Survey as a public domain product.  Information about obtaining the 1 foot data will be made as soon as the USGS releases it.

The Los Angeles Region Imagery Acquisition Consortium (LARIAC) Program is a collaborative acquisition program for digital aerial imagery data which has included the participation of 10 County departments, 30 municipalities, and four other public agencies.

The Consortium is a model for regional cooperation that improves the quality, access, and cost-effectiveness of high resolution digital aerial imagery. Knowledge transfer is increased through consortium program meetings, user groups, and various workshops that have been established in conjunction with the project. The imagery acquired will enable all participating jurisdictions to leverage this key geographic information asset for numerous decision support and business applications, thereby facilitating the effective and efficient delivery of services.
