Ogilvie Grain Elevator

The Ogilvie Flour Mills Co. Grain Elevator in Wrentham was constructed in 1925. It is a typical wood-cribbed grain elevator with a rare example of a balloon annex. With associated office, storage shed, and outbuildings this elevator is an example of a rapidly disappearing iconic Prairie structure.

All historical images were sourced from the book Homestead Country: Wrentham and Area, written and published by the Wrentham Historical Society. All modern images were collected by the Capture2Preserv team.

The Capture2Preserv team was contacted by the Ogilvie Wooden Grain Elevator Society (OWGES) to digitally preserve the grain elevator at Wrentham, AB. Over two days in August 2022, the grain elevator and auxiliary buildings were recorded with two laser scanners and a drone. Thirty-nine (39) scans were captured with the Z+F 5010X terrestrial scanner on the exterior (red dots) and interior (blue dots) of the grain elevator and auxiliary buildings. The Z+F 5010X scans were registered with Z+F Laser Control. Two passes were made with GeoSLAM ZEB Horizon mobile scanner with the ZEB Vision 360 camera providing coverage for the exterior of the grain elevator, office, engine room, and fuel sheds. The GeoSlam data was registered and processed in GeoSLAM HUB and Connect The drone, Mavi Mini 3 Pro, was used to capture images for photogrammetry and provide video footage of the site. The photogrammetry data was processed in Pix4D. All these data sets were brought together in Autodesk Recap and Cloud Compare to provide full coverage of the buildings.
