A short demo on actual 3D model comparison of nadir and oblique camera settings. The importance of knowing when and where to use nadir or oblique settings depends on what your project intends to analyze. More mission time is needed for oblique imagery. Longer flight times, more data sets, and more control points. Whereas just capturing nadir imagery will cut cost in processing and flight time. Understanding these photogrammetry concepts can be complicated which is why specific drones are being sold with fixed oblique cameras just for the construction industry. Flexibility is my goal and taking the time to understand camera settings like aperture, histograms, sensor pairing, solar reflectance are important photogrammetry skills that can make big differences when using drones for work. A simple position requirement like flying a sUAS may not be all you need to look for. The member of your team that has a strong GIS and Remote Sensing background may make your $800 drone produce more like a $25,000 drone. Being just a sUAS pilot and FAA certified may not cut it when it comes to professional projects. Buying a $25,000 drone with fully autonomous takeoff and landing just does not cut it either. So knowing the difference between nadir and oblique is simple. I hope this basic tutorial helps you ask more questions when considering a drone purchase or planning a mission.
