TerraSight delivers a complete suite of aerial data collection and geospatial processing services — built for the industries that demand accuracy.
LiDAR (Light Detection and Ranging) uses rapid laser pulses to measure distance and generate dense, high-resolution 3D point clouds of any terrain. Unlike photogrammetry, LiDAR penetrates vegetation canopy to capture true ground surface data — making it the industry standard for precision surveying in forested, complex, or difficult terrain.
TerraSight operates DJI L-series LiDAR systems capable of capturing up to 240,000 points per second with ±3 cm vertical accuracy — delivering data that engineers, surveyors, and mining operators can rely on for critical decisions.

Photogrammetry uses overlapping aerial photographs to reconstruct accurate 2D maps and 3D models of real-world environments. By analyzing the geometry of hundreds to thousands of images, our processing software produces georeferenced orthomosaics and 3D mesh models with survey-grade accuracy.
This method is ideal for large-area mapping, construction site documentation, and any application requiring both visual context and accurate spatial data.
| Maps | GeoTIFF, JPG, ECW |
| Models | OBJ, FBX, PLY |
| Point Cloud | LAS, LAZ, XYZ |
| Compatible With | ArcGIS, AutoCAD, Civil 3D |
Thermal and multispectral imaging captures data beyond the visible spectrum — revealing heat signatures, moisture variations, vegetation health, and surface anomalies invisible to standard cameras.
TerraSight deploys thermal and multispectral sensor payloads for applications ranging from agricultural crop health analysis to industrial inspection and gas leak detection.
Accurate volume measurement is critical in mining, construction, and earthwork — and traditional ground-based methods are time-consuming, expensive, and often unsafe. TerraSight delivers precise stockpile volumes, cut/fill calculations, and earthwork quantity reports using drone-based LiDAR and photogrammetry data.
Our volumetric surveys can be completed in hours rather than days, with results accurate enough to replace conventional survey methods for most applications.
TerraSight produces high-accuracy topographic maps and terrain models using drone-based LiDAR and photogrammetry — faster, safer, and more cost-effective than traditional ground survey methods.
Our topographic deliverables are compatible with all major engineering and GIS platforms, and meet the accuracy standards required for planning, permitting, and civil design.
A digital twin is a precise, data-accurate 3D replica of a real-world site — updated over time to reflect actual conditions. TerraSight produces digital twins from drone-captured LiDAR and photogrammetry data for construction sites, industrial facilities, mining operations, and infrastructure projects.
Digital twins enable remote inspections, stakeholder presentations, design validation, and progress tracking — reducing the need for costly site visits while improving decision-making.
