This UAV Photogrammetric Mapping Educational course is designed to teach professionals about the concepts behind UAV's, mission planning, data collection, data processing, georeferencing (control), quality assurance, lidar alternatives, attributing the information (classification), national standards, and products.  Please note this is different information than is covered in classes preparing you for the FAA drone pilot certificate.  While directly related to traditional fixed wing large camera format photogrammetry, the use of UAV in producing similar products has dramatic differences due to no pilot on board, smaller format hand held cameras, multi-ray overlaps of photos, self-calibration of cameras, automated pixel matching, and automated classification.  The use of airborne GNSS and inertial measuring system (IMU) sensors has changed the traditional georeferencing problem dramatically.  The sessions will utilize example data, example software, and time for questions and answers.
