Why Use a Drone
for Surveying?

Unparalleled Data Collection

Cover vast areas in a fraction of the time required by traditional ground survey methods — without sacrificing resolution or detail.

Excellent Positional Accuracy

PPK-equipped drones achieve down to 1 cm RMS horizontal accuracy — matching or exceeding traditional survey-grade equipment at a fraction of the cost.

Low Operating Costs

No pilots, no charter fees, no aircraft leasing. A drone survey costs a fraction of manned aerial surveys while delivering comparable or better data quality.

What Is a Drone Survey?

A drone survey uses downward-facing sensors — RGB, Multispectral, or LiDAR payloads — to capture aerial data. During an RGB survey, the ground is photographed multiple times with each image tagged with GPS coordinates.

After flight, images are processed in photogrammetry software to recreate geo-referenced 3D maps, contour lines, digital terrain models, or digital surface models for review in geospatial software.

Why Is a Drone the Best Option?

A drone flies at the ideal cruising speed and altitude for extremely high-resolution imagery. Airplanes and satellites fly too fast and too high to capture the same level of detail.

Drones capture imagery and GPS data simultaneously, giving you more information to create a more accurate rendering of the area — with flexibility no other platform can match.

Airplanes and satellites simply cannot match the resolution or cost-efficiency of a well-equipped survey drone at low altitude.

Survey Accuracy

How Accurate Can a
Drone Survey Be?

PPK GPS Accuracy Recommended

Horizontal (Best Case) 0.4 in (1 cm) RMS Vertical (Best Case) 1.1 in (3 cm) RMS Horizontal (Typical) < 1.57 in (4 cm) RMS Vertical (Typical) < 2.3 in (6 cm) RMS

PPK GPS is the standard for high-quality surveying drones. Event 38 PPK-capable drones use a dual-band receiver across all satellite constellations.

Standard GPS Accuracy No PPK

Raw GPS Error Up to 16 ft (5 m) Post-Processing (Best) 4.6 ft (1.4 m) RMS Post-Processing (Typical) Up to 9.8 ft (3 m) Absolute Accuracy Survey-Grade Only w/ GCPs

Standard GPS accuracy is suitable for general mapping but is not recommended for precision surveying applications requiring tight tolerances.

Accuracy Factors

What Affects
Survey Accuracy?

Quality of Equipment

Camera resolution, flight altitude, and the geolocation method all heavily influence accuracy. With high-quality equipment such as the Emlid Reach M2 and the high-resolution cameras Event 38 drones carry, these factors become a non-issue.

Satellites Overhead

The number and signal quality of satellites overhead can affect post-processing. Event 38 PPK-capable drones feature a dual-band GPS receiver that pulls signals from all satellite constellations — ensuring reliable reception even in remote locations.

Scenery of the Area

Mapping a dense forest canopy produces the same quality geotags as an urban environment, but photogrammetry software may struggle stitching imagery together when there are few distinctive shared features between images.
