For enterprises operating drones beyond visual line of sight (BVLOS), accurate terrain understanding is critical for safety and efficiency. Traditional 2D maps often fall short when pilots cannot visually assess terrain conditions, potentially compromising both operational safety and data quality.

FlytBase's new Point Cloud and Elevation Map Overlays address this challenge by bringing advanced 3D terrain visualization to BVLOS drone mission planning and execution, enabling centimeter-level accuracy and comprehensive terrain awareness.

Point Cloud and Elevation Map Overlays provide 3D terrain visualization for BVLOS drone operations, delivering centimeter-level accuracy and comprehensive terrain understanding when pilots cannot see the drone directly.

What is the Difference Between DTM, DSM, and Point Clouds

Understanding these mapping concepts is essential for effective BVLOS operations:

Digital Terrain Models (DTM)

Represents bare ground surface without vegetation, buildings, or structures.

Best for BVLOS operations:

  • Safe altitude planning and flight path optimization
  • Flood analysis for emergency response missions
  • Infrastructure corridor mapping for utility inspections
  • Baseline terrain analysis for construction projects

Digital Surface Models (DSM)

Includes all surface features like buildings, vegetation, and power lines at actual heights.

Critical for autonomous drones:

  • Urban obstacle avoidance and building height data
  • Vegetation canopy analysis for agricultural operations
  • Line-of-sight calculations for communication towers
  • Complete environmental awareness for safe navigation

Point Clouds

Millions of precise 3D coordinate points (X, Y, Z) with centimeter-level accuracy.

Generated through:

  • LiDAR sensors: Direct laser measurement using professional LiDAR systems
  • Photogrammetry: Processing overlapping aerial images with advanced algorithms
  • Hybrid methods: Combining multiple data sources for comprehensive coverage
