Surveying

Surveyors use drones to measure land accurately over large areas, producing topographic maps and elevation models.

Example missions

Lawnmower grid

Topographic survey

A double-grid (crosshatch) pattern with high overlap improves elevation accuracy.

Why this pattern? Parallel, overlapping lines let mapping software match features between photos. More overlap = better models, but more photos and flight time.

What drones do here

Produce topographic surveys and contour maps
Create digital elevation and surface models
Map corridors for roads and pipelines
Supplement ground surveys in hazardous terrain

Real-world examples

Topographic mapping
A drone with RTK/PPK GNSS and ground control points can map a site to a few centimeters.
LiDAR under trees
Laser scanners record returns through gaps in vegetation to measure the bare ground below.
