Kerala's leading geospatial survey company. UAV LiDAR, photogrammetry, DGPS, total station, bathymetry, and corridor mapping — combined into a single, certified workflow.
DGCA-certified pilots · Licensed surveyors · CORS network integrated · 3,000+ sq km surveyed · 50+ government projects
Where cameras see leaves, LiDAR sees through them. Our drone-mounted laser scanners fire millions of pulses per second — peeling back forest cover to deliver bare-earth terrain models that photogrammetry simply cannot produce.
High-resolution aerial imagery processed through structure-from-motion pipelines into centimetre-accurate orthomosaics, elevation models, and 3D meshes. The fastest, most cost-effective way to map large open terrain.
Drone data is only as accurate as its ground control. Our licensed surveyors establish and verify every GCP against the national CORS reference network — and certify all outputs with the legal documentation your tender requires.
We select and combine the right survey technology for each project — no one-size-fits-all approach.
High-resolution drone image capture processed into orthomosaics, DEMs, DSMs and 3D point clouds. Ideal for large-area topographic mapping.
2–5 cm accuracyDJI Zenmuse L1/L2 LiDAR payload delivering 100+ pts/m² point clouds, DTMs through vegetation, and precise corridor data.
3–5 cm accuracyDifferential GPS with full CORS network integration for sub-centimetre GCP placement and ground control across large project sites.
Sub-cm accuracyElectronic theodolite + EDM for precise boundary demarcation, engineering layouts, and spot-level surveys requiring legal-grade precision.
Legal gradeClassical levelling for establishing benchmarks, road alignments, and cross-sectional profiles — combined with drone data for complete site understanding.
Benchmark gradeSimultaneous Localisation and Mapping for indoor environments, tunnels, confined spaces, and GPS-denied areas — dense 3D models without GCP dependency.
GPS-denied zonesGround Penetrating Radar for subsurface utility mapping, void detection, rebar mapping, and geological investigation — non-destructive.
SubsurfaceAcoustic sonar and drone-integrated bathymetric surveys for rivers, reservoirs, harbours, and coastal zones — underwater topography and volume data.
Underwater mappingWe don't just fly drones — we engineer survey solutions. Every project uses a combined methodology: selecting the best-fit sensor combination, ground control strategy, and processing pipeline to meet your accuracy specification.
Real projects. Real terrain. Real accuracy.
Georeferenced GeoTIFF at 2–5 cm GSD. WGS84 / local CRS on request.
Digital elevation models with contour maps at client-specified intervals.
Classified, colourised LiDAR point clouds compatible with ArcGIS, AutoCAD, Civil3D.
DWG/DXF cross-sections, profiles, and feature extraction for engineering use.
Cut-fill analysis and stockpile volume calculations with before/after comparison.
Full methodology documentation, accuracy assessment, and GCP report for tender compliance.
Every survey project is backed by qualified professionals — not just drone operators.

We select and integrate the right combination of methods for every project — from open terrain to GPS-denied underground environments.
Structure-from-motion processing of overlapping drone images. Delivers orthomosaic, DSM, DTM, point cloud, and 3D mesh. Best for open terrain, construction, agriculture, and urban mapping.
GSD to 1 cmActive laser scanning from drone platforms. Penetrates vegetation canopy to deliver bare-earth terrain models. Best for forestry, flood modelling, corridor surveys, and dense ground cover areas.
100+ pts/m²Differential GPS using CORS reference stations. Used for establishing ground control points, boundary surveys, and precision positioning where absolute accuracy is critical.
Sub-cm horizontalConventional survey instruments for precision boundary, structure, and alignment surveys — combined with drone data to verify accuracy and survey areas inaccessible to drone flight.
Legal gradeSimultaneous Localisation and Mapping using LiDAR in GPS-denied environments. Maps tunnels, interiors, underground mines, and confined spaces with millimetre accuracy.
Millimetre accuracySubsurface mapping using radar pulses. Detects buried utilities, voids, foundations, and subsurface anomalies — integrated with drone photogrammetry for combined surface + subsurface datasets.
SubsurfaceAcoustic sonar-based underwater terrain mapping. Reservoir bed profiling, river cross-sections, coastal seafloor mapping, and port/harbour surveys — combined with drone photogrammetry for shoreline integration.
Underwater mappingMultispectral imaging for vegetation health (NDVI), agricultural monitoring, and environmental assessments. Thermal imaging for solar panel inspection and power line monitoring.
NDVI / ThermalEvery Dronimagination survey is designed around the accuracy requirement — not just the technology. We integrate CORS reference stations for absolute positioning, use calibrated GCPs for photogrammetry projects, and verify all outputs against independent check points before delivery.
