The TOUR’s “air force,” as Lovell describes it, began mapping courses in spring 2022 with handheld devices as well as fixed-wing and hovering drones. Using a laser-based LiDAR system, trees are mapped to “every individual tree, branch, leaf.” A method of photogrammetry – “really fancy stitching together of photographs” – builds the 3D model that creates TOURCAST, allowing fans to “navigate around multiple dimensions, multiple places and multiple angles,” Lovell said.
