1. Final Meeting Development of Harmonised Indicators and Estimation Procedures for Forests with Protective Functions against Natural Hazards in the Alpine Space Basic Data

2. Final Meeting Overview on data used: –NFI data/models –Thematic data –Digital terrain model –Landsat imagery –LiDAR –Digital aerial photography

3. Final Meeting NFI data: –From four alpine countries -Austria -Switzerland -Slovenia -Germany

4. Final Meeting NFI data: –Forest Mapping -Forest/Nonforest –Protective effect estimation -Volume/ha -Stems/ha -Basal area/ha -DBH -Tree height

5. Final Meeting NFI models: –Protective effect estimation -Crown coverage -Basal area -BHD

6. Final Meeting NFI models: -Basal area G/ha = 0.7819 * V 0.6719 G/ha = basal area, V = Volume/ha (m 3 /ha)

7. Final Meeting NFI models: -DBH DBH = -129.574 + 1,7114 * HnDSM + 8.8813 * HDTM DBH = Breast Height Diameter in cm HnDSM = height from the nDSM in dm HDTM = height from the DTM in hm

8. Final Meeting NFI models: -Crown coverage TCC = 0.236 - 0.1461 * HDTM -0.1227 * Hm + 4.0624*log(V) TCC = total crown cover Hm = Mean tree height (m) HDTM = height from the DTM (hectometres) V = Volume/ha (m 3 /ha) The coniferous crown cover (CCC) is then estimated by multiplying TCC with the volume fraction of coniferous trees.
