Principles of LIDAR Technology for Distance Measurement in Forestry

 What is the principle behind LIDAR technology for distance measurement in forestry?

Answer with Step by Step Explanation

4. Multiple Returns: In forestry, each laser pulse can result in multiple returns. These returns can indicate different points within the canopy of trees, allowing for detailed measurements of vegetation density and structure.

5. Data Processing: By analyzing the return signals, LIDAR can create precise 3D maps of the forest canopy, identifying tree heights, canopy cover, and terrain elevation.
