UAV-based aerial surveys producing centimetre-accurate orthomosaics, 3D point clouds, digital terrain models, and volumetric reports — covering hectares per hour with precision that rivals traditional survey methods.
Drone photogrammetry uses Structure-from-Motion (SfM) algorithms to reconstruct precise 3D geometry from overlapping aerial photographs taken by UAVs. The result is a rich set of geospatial outputs — orthomosaics, point clouds, DEMs, and 3D meshes — generated in a fraction of the time and cost of traditional survey methods.
Planora operates a fleet of 20+ enterprise UAVs including DJI Matrice 350 RTK, Phantom 4 RTK, and senseFly eBee X fixed-wing platforms. Our pilots are DGCA-licensed and our missions comply with all Indian civil aviation regulations.
With integrated RTK GPS on our drones, we achieve absolute positioning accuracy without the need for extensive ground control points — though we always deploy GCPs as a best-practice quality check on engineering-grade projects.
Planora's UAV fleet can cover 2,000+ hectares per day with the eBee X fixed-wing, making large-area corridor and agricultural surveys fast and economical.
Weekly drone surveys to track earthwork progress, measure cut/fill volumes, and verify grading compliance against design.

High-resolution DTMs for hydraulic modelling, flood risk delineation, and watershed analysis in data-sparse areas.
Marketing-quality aerial views, site context models, and 3D flythrough animations for development projects.
Flight path design using Pix4DCapture or DJI Pilot 2 — calculating optimal altitude, overlap, GSD, and waypoints. NOTAM applications filed and airspace clearance obtained from DGCA/AAI where required.
Targeted GCPs and Check Points are laid out and precisely surveyed using RTK GNSS. Minimum 8 GCPs per flight block for engineering-grade accuracy. Points are visible from 50–100m AGL.
Fully autonomous mission flown at pre-planned altitude and speed. Camera triggers at calculated intervals; onboard RTK or PPK records precise photo-centre coordinates for each image.
In-field laptop review of image sharpness, overlap coverage, and exposure consistency. Re-flights are conducted immediately if any strips are substandard — before leaving the site.
