How We Work

Our Technology

Three sensor modalities, RTK/PPK precision GPS, rigorous GCP deployment, and proven processing pipelines — delivering reliable geospatial data every flight.

Sensor Platforms

Three Modalities. One Truth.

RGB sensor drone
01

RGB

High-resolution colour cameras capture overlapping images processed into photogrammetric 3D models, orthomosaics, and surface models. The workhorse for topographic mapping.

Resolution
20 MP
GSD
2.5 cm
Accuracy
±5–10 cm
Coverage
200+ ha/day
LiDAR sensor drone
02

LiDAR

Laser pulse ranging generates dense 3D point clouds that penetrate through vegetation canopy — revealing true ground surface even under dense forest cover.

Sensor
240,000 pts/sec
Density
240+ pts/m²
Returns
Multiple return
Range
Up to 300m AGL
Thermal sensor drone
03

Thermal

Dual-sensor design — radiometric thermal and 20MP RGB captured simultaneously. Measures absolute surface temperature, not just relative heat.

Sensitivity
<50 mK NETD
Temp Res
0.05°C
Range
-20°C to 150°C
RGB
20MP simultaneous
How We Deliver

Survey Workflow

01

Site Assessment & Flight Planning

Every project begins with a detailed site assessment — area extent, terrain complexity, required accuracy, regulatory airspace, and optimal flight parameters.

02

Ground Control Points & RTK Setup

GCPs surveyed with RTK or total station GPS to sub-decimetre accuracy. For large corridors, PPK GPS eliminates base station range limitations.

03

Autonomous Aerial Data Capture

DGCA-certified operators execute the approved flight plan with real-time telemetry monitoring for sensor health, GPS signal, and battery status.

04

Data Processing & Quality Control

Raw data processed using photogrammetric and LiDAR pipelines. Outputs validated against independent check points.

05

Deliverable Production & Handover

Final deliverables in client-specified formats — GeoTIFF, LAS, DXF, SHP, OBJ, GLB, and PDF reports — delivered via secure cloud link or portal.
