RecapSteve Welebny, Geospatial Products Manager, and Wes Weaver (MUSA '13), Aerial Sensor Operator at Keystone Aerial Surveys, Inc. discussed new products and innovations in digital imagery and photogrammetry. The Philadelphia-based company, which specializes in aerial imaging and geospatial data acquisition (e.g. LiDAR), is currently developing a method called a “Key-3D” point cloud—a highly accurate elevation model derived entirely from two-dimensional digital imagery. This presentation included a brief overview of aerial data acquisition and its role in mapping and GIS, photogrammetry, 3D modelling and the Key-3D point clouds. The speakers discussed uses and applications developed from LiDAR data, photogrammetrical processes and three dimensional mapping and modelling.
