In this episode, Stewart speaks with James Rush, Lidar Subject Matter Expert, Allen & Company, about his employer and his personal journey into lidar management. Allen & Company has roots in conventional land surveying, but its offerings today include extensive services in laser scanning of buildings, producing deliverables such as BIMs and digital twins. To this end, it has a subsidiary, Allen3D. James discusses some of the projects on which Allen is working and examines how the specifications are reached in discussion with clients, paying appropriate attention to published standards. He also describes an initiative at Tucker Ranch, near the company's headquarters in Winter Garden, Florida, in which he arranged for 17 collections of lidar point clouds of a small area, to provide a most unusual reference data set for many purposes.
