Light Detection and Ranging – A Review
Source: TopScan, Germany
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)
