The Regional Aerial Photo Consortium enables the joint purchase of digital aerial orthophotography by local governments and nonprofit groups in greater Portland. 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.

Summer 2019 lidar corrections
In December 2020, members of the consortium came forward identifying issues with the raster and LAS files from the summer 2019 acquisition. These issues were shared with the vendor, GeoTerra, prompting a second round of QA and corrections. The lidar technical team has been meeting regularly with the vendor to discuss these issues and check-in on the correction status and process.
The following table is an estimated corrections schedule from the vendor. This will be updated regularly and have more detail about Metro's plan for redistribution later this Spring.
