3DroneMapping accomplished a high-accuracy aerial survey and drone mapping venture for the Canaan Challenge close to Manzini, eSwatini, on behalf of Third Lens. The survey coated roughly 380 hectares, with an extra bridge website situated 5 km to the east, and was undertaken to help future website growth and planning.
Establishing Correct Floor Management for Drone Surveys
Correct outcomes begin on the bottom. For this venture, 3DroneMapping established a exact GNSS floor management community throughout the location utilizing dual-frequency receivers and post-processed positioning strategies. This ensured centimetre-level accuracy for each photogrammetry and LiDAR knowledge merchandise.

Customized Drone Platform and LiDAR Aerial Survey Expertise
The survey was flown utilizing a custom-built 3DroneMapping drone platform, designed in-house for long-range, high-precision aerial surveys. The sensor payload included:
⦁ A 102 MP calibrated RGB mapping digital camera
⦁ A high-density LiDAR survey system
This setup allowed us to seize detailed imagery and dependable terrain knowledge, even in areas with steep or advanced topography.

Environment friendly Aerial Knowledge Seize Over Giant Areas
Flight operations had been accomplished over sooner or later, with 72 km flown in underneath three hours. Cautious flight planning ensured optimum picture overlap and constant floor decision throughout the location. Whereas winter shadows affected some RGB imagery, the LiDAR knowledge remained unaffected, delivering reliable floor fashions all through the survey space.
Drone Survey Deliverables for Web site Growth Planning
The ultimate dataset met all accuracy necessities and was delivered in industry-standard codecs, together with:
⦁ Excessive-resolution orthomosaic imagery
⦁ Digital Terrain Fashions (DTMs)
⦁ Labeled LiDAR level clouds
⦁ Contours and CAD-ready outputs
These deliverables present a dependable basis for engineering design, environmental research, and growth planning.
