Drone Aerial Systems

LJA Surveying provides aerial data collection and inspection services using unmanned aerial systems (UAS) dedicated to providing a safe, cost-effective, and efficient way to gather actionable data for their business. We have collaborated on a number of “industry firsts” providing successful proof of concept flights for industrial, commercial, and government entities. This experience has given us a unique perspective on the advances and uses of UAS technology in a multitude of industries. From oil and gas assets, forestry and agriculture to construction and bridges, LJA Surveying has the expertise and technology to capture the quality data you need, including thermal imagery and methane detection, using the latest UAS technology and instrumentation. Our staff are problem solvers in their fields. We look at challenges as an opportunity to innovate, and we have the talent to get the job done.

We hire only FAA certified pilots to fly our UAS. We have Section 333 Exemption from the FAA to conduct commercial UAS flights in the USA. We are one of only 8 companies to pass the rigorous testing and vetting process sponsored by Texas A&M University, TEEX, Lone Star Center for Excellence, FAA, and NASA. We were specifically recognized for “setting a new standard in safety and professionalism.” We are fully insured for your sake and ours.


UASs with Light Detection and Ranging (LiDAR) provide survey-grade laser mapping and photogrammetry with accuracies down to a few centimeters. This efficiency allows the creation of 3D models to be used in planning, design, measurement, and decision making throughout a project’s life cycle, including construction and owner occupation. The demand for UASs with LiDAR is growing quickly, and their quality and usage will continue to expand as the technology develops. Using LiDAR is very cost effective compared to traditional methods.


The use of aerial footage, photos, and data from UASs is changing the way construction companies acquire their survey data. By using our proprietary ground control points, aerial data collection methods, and Trimble’s R10 RTK GNSS system, we can produce highly accurate map data in any format requested. Other aerial data such as infrastructure inspections, thermal imagery of machinery to prevent costly break downs, and publicity photos and videos can all be used to a company’s advantage.


The vast infrastructure of the United States is aging, and the importance of regularly performed, mandated inspections and surveys becomes paramount. Energy, Oil, and Gas: Every year pipelines are subject to leaks and explosions from defects previously undetected. Companies must now allocate significant resources to address failing infrastructure. UASs provide a revolutionary method of capturing the necessary data required while creating dramatic savings over traditional methods. Bridge: Traditionally these inspections and surveys were performed by individuals on scaffolding or on rope/cable deployment. This process is slow, costly, and dangerous. We can provide HD video or thermal data collected by specialized UASs.
