In December 2017, NV5 acquired Skyscene, LLC  (“Skyscene”), a leading provider of Unmanned Aerial Vehicle (UAV) flight services headquartered in San Diego, California. The aerial survey and mapping company operates fixed wing and multirotor UAV’s while carrying the most advanced remote sensing equipment. They can cover thousands of acres a day providing 2D Orthomosaics, Contour Maps, 3D Densified Pointclouds, as well as having the ability to calculate all volumetrics on the property such as cut, fill, and total volume. These metrics are far greater than traditional ground survey because they can place an XYZ coordinate on every inch of the property getting an extremely accurate measurement. Integrating NV5’s LiDAR (Light Detection and Ranging) mapping technology with Skyscene’s UAV flight services positions NV5 as one of the leading UAV LiDAR aerial mapping service providers in the nation. Traditionally provided with fixed wing aircraft or helicopters, the use of UAV LiDAR adds value to our clients by providing higher resolution mapping, rapid mobilization, and more cost-effective services than can be achieved using manned aerial vehicles or traditional survey methods.
