 Hello, I'm Carl Heidemann, one of the LIDAR science instructors in the Penn State Online Geography Program. Interestingly, my first career was as a stage lighting designer. I believe that my affinity for three-dimensional modeling in that environment ultimately led to 3D modeling with LIDAR. My LIDAR career began about 20 years ago, while the technology was still in its formative stages. Initially, I focused on product development, process automation, later shifting into writing standards and specifications for both the ASPRS and the USGS. I now focus primarily on teaching. LIDAR has always been fascinating to me with a wealth of information still undiscovered within the point clouds. I hope that I can instill my students with a similar passion for LIDAR and a desire to continue exploring this ever-developing technology.
