Update July 30, 2019: Collection of the imagery is nearly complete. From Geoterra: The entire project has been flown, but we have a few spots to re-acquire due to unavoidable small clouds/shadows.
Update July 22, 2019: Collection of the imagery and lidar is progressing. The project is a little behind compared to previous years due to the switch in the project management in June and the uncooperative weather. We are now seeing some solid clear days and are expecting to complete the imagery collection soon. Luckily it has been cool and the vegetation has stayed relatively green. The decision was made the week of July 15 to use a lidar collection that is already in progress. The technical specification is different but we are confident it will meet the needs of the consortium members. A big shout out to Clean Water Services and City of Portland for helping with the technical evaluation of our options. One of the primary reasons for the decision is to reduce the risk of not being able to collect the data before leaf fall or water levels rising in the fall.

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.
