Aerial Photography
Improve your project development plans with high-resolution imagery from our aerial photography experts and industry-leading photo equipment.
When high-resolution aerial photographs are needed, HGA can help capture a complete view of large areas. Regardless of project size, our ASPRS-certified photogrammetrists work with the client to identify and acquire high-quality imagery to help track construction progress, development planning, environmental, pipeline construction, and disaster recovery planning. Through access to the latest technology, HGA is ready to mobilize our flight operations team and deploy aircraft with large-format metric cameras to provide the very best aerial photography possible.
HGA utilizes industry-leading software to process all projects in-house, resulting in crisp, digital aerial imagery. Our professionals have extensive photogrammetric experience in all phases of mapping and other mensuration requirements, including planning and supervising photography, managing mapping projects, and interpretation.

Unmanned Aerial Systems
Our unmanned aerial systems (UAS) deliver high-resolution data that captures exceedingly precise points to use for design, calculations, and map products—while improving safety, planning, and design.
HGA’s UAS solutions deliver hands-off piloting visualization from takeoff to landing. Our unmanned aerial vehicle (UAV) solutions are more flexible and cost-effective than piloted aircraft—and can be deployed repeatedly, rapidly, and at reduced costs.
Our UAS team has the skills and capabilities to deploy an unmanned vehicle any time from any location. We have an in-house specialist with a Remote Pilot in Command (RPIC) license obtained from the Federal Aviation Administration and multiple staff trained as pilots and visual observers. Our onboard flight computer system can cover hundreds of acres in minutes, while our high-resolution camera sensors capture hundreds of images in the locations necessary to generate high-density 3D point cloud models. Real-time flight and data collection information are streamed to the ground station from all aircraft utilizing onboard telemetry radios. Our advanced technologies can vastly reduce the time spent collecting data, resulting in more accurate project plans, models, and operations.
HGA’s UAS solutions can assist in the planning and design of any project, including construction sites, route development, infrastructure inspection, and environmental studies. We will help you reduce collection/inspection time, allowing for faster analysis and monitoring, all from one short flight.
