Foliage Height Diversity (based on point height above ground)
The Foliage Height Diversity (FHD) metric was first described by MacArthur & MacArthur (1961) for describing bird species richness. He applied the Shannon-Wiener information index to the proportion of foliage mapped in three different height layers manually in forest. Here, we use the penetration rates as described above as a proxy for foliage biomass to calculate FHD from LiDAR data.
can := BE_PR_CAN * ln(BE_PR_CAN) und := BE_PR_UND * ln(BE_PR_UND) reg := BE_PR_REG * ln(BE_PR_REG)
If a term is not finite set that term to zero.
BE_FHD := - (can + und + reg)
