LiDAR-Based sampling procedures for regional forest biomass and carbon estimation – On-going and New Initiatives Erik Næsset and Terje Gobakken Norwegian University of Life Sciences Dept. of Ecology and Natural Resource Management Paul Bolstad and Ron McRoberts University of Minnesota Dept. of Forest Resources

2. Light Detection and Ranging – A Review • 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) Source: TopScan, Germany Source: Hyyppä et al. 1999.

3. What is laser scanning?

4. Laser scanning Detailed studies of wood quality

5. Laser scanning Developing a national system for inventory of biomass/carbon stocks combining airborne laser and field data
