Update February 27, 2020: Orthophotography Metro sent QA comments to Geoterra and is expecting final delivery with requested color correction the week of March 2nd. Hard drive distribution with copied photos will begin the following week. Lidar Second sub area delivery has been received. Metro continues to request consortium members to assist with the QA of the product.
Update January 29, 2020: Orthophotography Metro is completing the QA of the final delivery product. Lidar First sub area delivery has been received. Metro is requesting consortium members to assist with the QA of the product.
Update December 23, 2019: Orthophotography Ortho generation and review are complete. Creation of final GeoTIFFS, overviews and color enhancement in progress. Expected shipment of hard drive to Metro for review by January 6th. Lidar Data density and file size are influencing production speed for all aspects of the lidar project. Planned overlap during acquisition is resulting in density as high as 70 points/m² in some areas. Estimates for completion timeline have been updated in the Project Status table on this page.
Metro has paid the first payment to Geoterra and invoiced the 4 highest contributing consortium members for the first of their two payments for the project.
Update October 30, 2019: The project schedule has been updated below. The consortium met yesterday to discuss derivatives from the lidar.
The preliminary photo web service is available. This is the first automated pass to stitch the individual images together. There are known issues. Use your RLIS credentials to login and access the service.

The pilots for photos and lidar are under review and Metro will be providing feedback to Geoterra shortly. If you are interested in getting access to the pilot, email [email protected] and cc [email protected].
Update September 9, 2019: From Geoterra: Completed acquisition [of the lidar] on the 31st of August for remaining small lines in the northwest AOI. All recently acquired data is being reviewed for potential re-flights and is expected to complete their initial review by the end of this month. Geoterra has provided a project schedule based on the last day of photo and lidar acquisitions. Once Metro has reviewed them, the scheduled on this page will be updated.
About
The Regional Aerial Photo Consortium enables the joint purchase of digital aerial orthophotography by local governments and nonprofit groups in the Portland area. Consortium purchase reduces each member's cost of obtaining photography through cost sharing. The digital imagery available includes the urban areas of Multnomah, Clackamas and Washington counties. In some years, the coverage is expanded to include rural areas, lidar and lidar derivatives. The intent of the consortium is to provide for a cost-effective means to acquire digital orthophotography on an annual basis.
The urban area covers 656 square miles. The urban/rural coverage covers 973 square miles.
