High Density LiDAR Services and Product Examples by 3Di, Inc_02172014

  1. 1. High Density LiDAR & Photogrammetric Point Clouds 3Di | GeoTerra Mapping Group
  2. 2. What is “High Density” 3Di | GeoTerra Mapping Group
  3. 3. How to we achieve high point densities? 1. Points per meter……low & slow 2. Double Coverage 3. System Specifications 4.Multiple Returns or Full Wave Form 12 to 20 points per square meter! 3Di | GeoTerra Mapping Group
  4. 4. What do we do with so many points?  Superior vegetation penetration  Object identification (manual and automated processing)  Detection of small linear objects  3D City Modeling / Mapping  Improved vegetation analysis  Electrical transmission - existing  Integration with Ground Based LiDAR 3Di | GeoTerra Mapping Group
