Macro vs. Micro: A Hands-on Workshop for the Tools of Documentation

Special Offer: Two events in one day! Attend this workshop, plus the 34th Annual Pomona Heritage Home Tour, and save $10! Simply select the two-event package on the registration form. If you'd like to purchase just the Pomona Heritage Home Tour, you may register here. Work hands-on with some of the classic and current technology used for documentation and evaluation of historic buildings, structures, and landscapes. Learn from industry professionals the ways in which drones and UAVs, GigaPan high-resolution panoramic photography, Matterport 3D camera scans, and nondestructive tools (i.e. radar and ultrasonic technology) provide a range of perspectives. Each technology establishes a different perspective - macro, micro, or somewhere in between. Whether looking from 100 feet above, or looking "inside" of walls and locating building obstructions, these tools have their purpose and their limitations. The workshop will include an overview, including demonstrations and hands-on experience and will also include a behind-the-scenes "first look" during the rehabilitation of the Pomona YMCA building.
