UAS (Unmanned Aircraft Systems)


raSmith has applied its survey knowledge base, experience since 1929, and solid grasp of technology to the use of unmanned aircraft systems (UAS). Also referred to as drones, UAS are one of several tools we have available for surveying and mapping in addition to 3D laser scanning and hydrographic surveying.

We currently use a series of aircraft and primarily photogrammetric payloads to capture imagery that is post-processed and scrutinized as part of our customized QA/QC process, which incorporates survey-grade ground control points and conventional survey check shot comparisons, to create a variety of data sets including orthorectified imagery, 3D point clouds, 3D surfaces, and meshes. We also further refine these data sets to create topographic and volumetric maps and exhibits.

raSmith has seven UAS with our newest drone being the Altus LRX — a large stagger prop multirotor aircraft, capable of carrying a variety of payloads including inspection, photogrammetric, multispectral, and LiDAR sensors.

Our on-staff team of FAA (Federal Aviation Administration) Certified UAS Pilots are educated in FAA guidelines, ensuring clients that we know what can and cannot be done. raSmith has been at the forefront of expertise in UAS technology, having obtained a Section 333 Exemption and associated blanket COA (certificate of authorization) from the FAA in 2015. As we discover additional applications for the technology, we are continually demonstrating new applications of UAS to our clients.

Advantages of aerial drone surveys include enhanced data collection on a wide range of projects; ability to better map areas that may otherwise be difficult or unsafe to traverse; and in certain instances, a more cost-effective means of collecting data versus traditional methods.
