Drone surveying is revolutionizing the world of geospatial data collection, but for many engineers, developers, and project managers, it remains a mystery. In this blog, we tackle the most frequently asked questions about drone surveying — the ones people hesitate to ask — with clear, professional answers. Whether you're managing a construction project, planning an infrastructure upgrade, or exploring new development opportunities, understanding how drone surveys work can unlock new levels of speed, safety, and accuracy.
What Is Drone Surveying?
Drone surveying is the process of using unmanned aerial vehicles (UAVs) equipped with high-resolution cameras, LiDAR sensors, and other data-gathering technologies to capture aerial imagery and topographic data. These datasets are processed to produce 2D maps, 3D models, and volumetric measurements that can be integrated into CAD and GIS platforms.

How Accurate Is Drone Surveying?
Very accurate. When performed by experienced professionals using survey-grade UAVs and ground control points (GCPs), drone surveys can achieve horizontal and vertical accuracies within 1 to 2 inches (2.5 to 5 cm). Accuracy depends on several factors including:
- Altitude of flight
- Camera quality
- Ground control calibration
- Environmental conditions
For best results, FAA-licensed drone pilots and licensed land surveyors collaborate to ensure every survey meets regulatory and technical standards. According to the American Society for Photogrammetry and Remote Sensing (ASPRS), modern photogrammetric methods are now widely accepted in professional engineering applications.
What Can Drone Surveys Be Used For?
Drone surveying is incredibly versatile. At Darling Geomatics, we’ve used it for:
- Land development planning
- Construction site monitoring
- Energy infrastructure inspection
- Environmental assessments
- Volume measurements for mining and excavation
- FEMA floodplain analysis

Are Drone Surveys Legal and FAA-Approved?
Yes. All drone surveys conducted by Darling Geomatics comply with FAA Part 107 regulations and Section 333 exemptions. Our UAV pilots are certified, and we always acquire proper flight authorizations for every project site, including restricted airspace when necessary.
You can read more about FAA regulations on FAA.gov.
How Long Does a Drone Survey Take?
It depends on the size and complexity of the site. A small residential parcel might take under an hour to survey, while a large solar farm or construction site can be flown in a single day (covering 1,000-2,000 acres). Data processing typically takes 1-3 business days depending on deliverables requested.
Darling Geomatics' drone teams prioritize efficiency without sacrificing quality. Learn how we tailor timelines on our Drone Survey Services page.
