Question 1

What is drone surveying?

Accepted Answer

Drone surveying uses RTK-equipped UAVs to capture high-resolution aerial imagery that is processed into accurate point clouds, orthomosaics, digital elevation models, and 3D mesh models. It is faster, safer, and often more cost-effective than traditional land surveying for large sites.

Question 2

How accurate is drone surveying compared to traditional surveying?

Accepted Answer

RTK drone surveys achieve accuracy of 1-3cm horizontally and 2-5cm vertically when using ground control points (GCPs). This is comparable to traditional survey methods while covering much larger areas in less time.

Question 3

What is construction progress tracking with drones?

Accepted Answer

Construction progress tracking uses regular drone flights over a construction site to document progress with aerial photos, 4K video, orthomosaics, and volumetric data. This allows project managers to monitor earthworks, compare as-built to design, and produce progress reports without setting foot on site.
