TAKE HOME MESSAGES
• Terrestrial LiDAR provide promising technology for documentation• Safe
• Accuracy
• Detail• Detail
• It’s the future for resource inventory
• Potential comes with lots of limitations• Line of sight
• Weather
• Processing
• Automated means of extracting useful parameters needs to be formulated
