LiDAR Survey & Data Processing

LiDAR Survey & Data Processing is an advanced geospatial solution that uses laser pulses to measure distances between the sensor and the Earth's surface. Millions of laser points are collected every second to generate highly accurate three-dimensional (3D) representations of the terrain and surrounding objects.

At AIMN Projects Pvt. Ltd., we utilize state-of-the-art LiDAR technology integrated with GNSS, IMU, UAVs, and advanced processing software to produce precise geospatial datasets. Our experienced team processes raw LiDAR point clouds into valuable engineering outputs such as Digital Terrain Models (DTM), Digital Surface Models (DSM), contour maps, elevation models, orthophotos, volumetric calculations, corridor mapping, and GIS-compatible data.

Our LiDAR solutions are widely used for highway planning, railway corridors, power transmission lines, smart city projects, flood modeling, mining operations, forestry analysis, pipeline routes, and large-scale infrastructure development.
