Mapping + Surveying Drones

Aerial mapping and surveying drones have revolutionized the way geospatial professionals collect data — delivering centimeter-level accuracy across large areas in a fraction of the time required by traditional ground survey methods. Global Drone HQ is your authorized dealer for professional mapping UAVs and photogrammetry/LiDAR payloads from DJI, Freefly, MicaSense, Sentera, and GeoCue.

Photogrammetry Drones

Photogrammetry uses overlapping aerial imagery to generate 3D point clouds, orthomosaics, and digital elevation models (DEMs). The DJI Matrice 400 paired with a Zenmuse P1 full-frame camera delivers survey-grade mapping accuracy with 45-min flight time and RTK positioning, covering hundreds of acres per mission. The DJI Mavic 3 Multispectral adds multispectral band capture to the photogrammetry workflow, enabling simultaneous RGB and NDVI mapping for precision agriculture and environmental monitoring.

LiDAR Mapping Drones

LiDAR generates dense 3D point clouds by measuring precise laser pulse return times. Unlike photogrammetry, LiDAR penetrates vegetation canopy to map the bare-earth surface below — making it essential for forestry, corridor surveys, and flood modeling. The DJI Zenmuse L3 for the Matrice 400 delivers 5-return point clouds at 240,000 points/second with 4–5cm vertical accuracy.

RTK GPS for Survey-Grade Accuracy

Real Time Kinematic (RTK) GPS eliminates the need for dense ground control point networks by correcting GPS errors in real time during flight, achieving 1–3cm horizontal and vertical accuracy. All our mapping drone platforms support RTK through DJI's D-RTK 2 base station or NTRIP network corrections.

Software Integration

Our mapping drones integrate with leading geospatial processing software including DJI Terra, Pix4D, Agisoft Metashape, and DroneDeploy, enabling streamlined workflows from flight planning through final deliverable production.
