When dense forest hides the ground from cameras, LiDAR sees through. HSSPL flies UAV-borne laser scanners over Himalayan hydropower corridors, pilgrimage infrastructure and project sites — delivering classified point clouds, bare-earth terrain models and contours where photogrammetry alone cannot. Our LiDAR work includes the complete Mata Vaishno Devi temple complex for the Shrine Board.
From a single UAV LiDAR campaign over a dense-forest hydro corridor: the raw true-colour point cloud, the elevation-classified cloud revealing the terrain, and the final orthomosaic with engineering contours.



Bare-earth DEM/DTM beneath forest canopy — the decisive advantage over photogrammetry on Himalayan hydropower and road corridors.
Roads, ropeways, transmission lines, penstocks and pipelines flown as strips — long alignments captured in days, not months of ground survey.
High-density scans of temples, townships and structures — as surveyed across the complete Mata Vaishno Devi temple complex for the Shrine Board.
A LiDAR survey uses a laser scanner — mounted on a UAV — that fires hundreds of thousands of pulses per second and measures their return time. The result is a dense 3D point cloud of the terrain and everything on it, accurate to centimetres, from which DEMs, contours and drawings are extracted.
Photogrammetry only sees what the camera sees — in dense forest it maps the canopy, not the ground. LiDAR pulses penetrate gaps in vegetation and return from the actual terrain, making it the only practical way to get accurate bare-earth models under forest cover.
With RTK/PPK trajectory processing and ground-control verification, typically 5–10 cm vertical accuracy on bare ground. Every HSSPL deliverable is independently checked against DGPS control points before handover.
Classified LAS/LAZ point clouds, bare-earth DEM/DTM rasters, contour plans at your specified interval, cross-sections and L-sections, GIS-ready shapefiles, CAD drawings (DWG/DXF) and a survey report with accuracy statement.
Roughly 1–3 sq km per flying day depending on terrain and point density; corridor projects progress 10–20 km per day in favourable conditions.
