Light detection and ranging a review
Light Detection and Ranging – A Review and carbon estimation

  • LiDAR = laser range finder

    • Ground elevations

    • Canopy heights

    • Structural information

      • Leaf area

      • Percent crown cover

      • Tree stocking density

  • Advantages

    • Cost efficient for large areas

    • High spatial resolution (~30 cm)

    • Numerous applications

      • Forest biomass, growth and change detection, carbon exchange

      • Wildlife habitat

      • Disturbance (e.g., pests, blowdowns)
