LiDAR Survey

High-Density 3D Mapping with Laser Precision

Cartospatial Technologies offers LiDAR Surveying services that provide incredibly accurate and high-density 3D data. Using airborne, terrestrial, and mobile LiDAR systems, we capture millions of laser points per second to create detailed topographic maps, terrain models, and feature-rich 3D representations of any environment—natural or built.

Key Features of Our LiDAR Surveys

  • High-Density Point Clouds
    • Up to several million points per second
    • Ultra-dense 3D data for micro-level terrain features
  • Multi-Platform Deployment
    • Airborne LiDAR (UAV, helicopter, or aircraft)
    • Terrestrial LiDAR for buildings, structures, and landscapes
    • Mobile LiDAR for road and railway corridors
  • Precise Elevation Mapping
    • Vertical accuracy up to 5 cm
    • Excellent for flood modeling, grading, and surface modeling
  • Vegetation & Obstacle Penetration
    • Captures ground-level data through foliage
    • Useful in forested and uneven terrain
