33 unmanned systems inside April/May 2017 June/July 2017 play on your screen. So that helps a lot in terms of operation and in terms of pilot control." Best Methods Van Rens covered the challenges surrounding all the big data now available, and how best to set up solutions suited for specific applications. He talked about the reasons behind the Riegl and Applanix partnership and the benefits real- ized by combining these companies' products. "For today's high-precision LiDAR to work effectively, from both data acquisition all the way to automated and semi-automated feature extraction, the integration between the GNSS and the LiDAR is critical to its success," he said. While some may consider LiDAR and pho- togrammetry competing technologies, Van Rens explained how they can both be quite helpful, working together. "Riegl believes that it's a multi-sensor world. Each technology has attributes that contribute to the overall quest for information, and tightly coupled integra- tion supports that quite effectively," he said. Chaponniere's presentation on the Benefits of Direct Georeferencing for Simultaneous LiDAR/ Photogrammetry Systems Versus Traditional Aerial Triangulation compared DG versus tra- ditional methods at a quarry site in France. He also showed how highly integrated, light- weight LiDAR systems today offer a variety of solutions for surveyors that are FAA Part 107 compliant. Simultaneous LiDAR/photo DG solutions, he said, deliver benefits such as: • Faster survey time, with less f light lines needed—and faster processing time • Reduction/elimination of the need to survey GCPs in the field • Safer operations, no disturbance, no operations down time • Faster data collection • Wider field of view • LiDAR surveys are not impacted by image correlation issues such as those caused by non- homogenous particles like snow and sand • An ability to capture fine infrastructures or objects (power lines, conveyors, etc.) After his fellow panelists demonstrated how a number of LiDAR solutions are currently available and working well with small UAS, Poss seemed convinced. "OK, I'm going from possibly wrong to shot down in f lames and you can record that," he said jokingly late in the webinar. "Yes you can use LiDAR for small UAS." WATCH THE WEBINAR Want to learn more?

" Joe Hutton, director inertial technology and airborne products for Applanix WHILE SOMEWHAT CONTROVERSIAL, WE BELIEVE THAT LIDAR INTEGRATED WITH CAMERAS AND DIRECT GEOREFERENCING REPRESENTS THE PINNACLE OF ACCURACY AND PRODUCTIVITY, AND WILL SOON BECOME THE STANDARD PAYLOAD FOR MAPPING AND SURVEYING WITH UAVs." " An example of an FAA Part 107 compliant LiDAR UAV, many of which were addressed in the webinar. The benefi ts of Direct Georeferencing for simultaneous LiDAR/ photogrammetry systems versus traditional Aerial Triangulation can be shown in this image of a quarry site in France. caption.
