Thanks to Gerri Broman, the CSUAC is now available to support CC3! This has over 5000 images in PNG format and fills, already sorted in the CC3 file structure. And more is on the way! The current task is organizing 3000 structural images (buildings, roads, bridges, etc) with an intent of having it ready at the end of the month (early July for CC3).
