Asset & Geospatial Intelligence for Critical Infrastructure

There is no single price, because cost depends on the project. The main factors are the area or length to be covered, terrain and site access, the sensor used (RGB, thermal or LiDAR), RTK/PPK and ground-control requirements, the deliverables you need, travel to site, and processing effort. Inspection projects also vary by asset type and count. Share your site, scope and required outputs and our engineers will send a scoped quote.

Accuracy depends on the project specification, not on the drone alone. The main factors are the sensor, flight height and overlap, RTK/PPK positioning, ground control points and independent checkpoints, terrain and weather, and the processing method. We plan each mission to the accuracy you need, then validate coverage, positioning and data completeness before anything is delivered.

Yes, civil drone operations are permitted under India's Drone Rules, 2021. What applies to a given job depends on the drone category, the operation and the airspace. India's Digital Sky map divides airspace into green, yellow and red zones. Green zones do not need prior permission up to the permitted height, while yellow and red zones need permission first. Commercial operations also need registered drones and certified remote pilots. Lesoko flies with DGCA in-house pilots, checks airspace before every mission and follows pre-flight safety procedures.

Photogrammetry builds maps and 3D models from overlapping images. It suits open terrain and works well for orthomosaics, visual records and progress comparison. LiDAR measures with laser pulses, so it can capture bare-earth terrain beneath dense vegetation and suits corridors and complex terrain. Neither is always better, and some projects use both. We recommend the method that fits your terrain, accuracy requirement and deliverables.

You receive processed, usable outputs rather than raw images. For surveys these include orthomosaics, DSM/DTM/DEM, contours, point clouds, 3D models, and CAD and GIS files. For inspections they include thermal and RGB imagery, a geo-tagged defect register with severity classification, and an inspection report. For progress monitoring you receive orthomosaic comparisons and periodic reports. Where relevant, results come in a dashboard and in formats your team can import.
