The Los Angeles Region Imagery Acquisition Consortium (LARIAC) Program is a collaborative acquisition program for digital aerial imagery data which includes the participation of over 30 County departments, and 40 additional partner organizations including municipalities, other public agencies, and academic institutions.

Since its inception, the Consortium has served as 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 initiated as a part of the program.

The imagery acquired enables participating organizations to leverage a set of foundational geographic information assets. These data support a wide array of decision support, business, and research applications, and help to facilitate the effective and efficient delivery of public services.

Each LARIAC cycle lasts three years, with LARIAC7 being the most current, complete iteration of the program. Both AccuPLUS® (10cm2 resolution) orthogonal and oblique imagery capture were obtained in early 2023.

A new project, our LARIAC Frequent Image Capture program, initiated during LARIAC 5 acquires imagery additional during the intermediate years of the three-year cycle. This high-resolution, orthogonal, and oblique (starting Fall 2021) RGB imagery is included in the CONNECT platform for our users.

The LARIAC7 AccuPLUS® (10cm2 resolution) orthogonal and oblique image acquisition began in early 2023. Final imagery was delivered in February 2024.

The LARIAC7 QL1 aerial lidar acquisition began in late September 2023 and  completed in January 2024. The overall project is 84% complete as of August 31, 2024.
