treepos_RL | R Documentation |
Detects and computes the location and height of individual trees within
the LiDAR-derived Canopy Height Model (CHM). The algorithm implemented in this function
is local maximum with a fixed window size. Carlos A. Silva et all.: R package rLiDAR
treepos_RL(chm = NULL, movingWin = 7, minTreeAlt = 2)

Canopy height model in |
movingWin |
Size (in pixels) of the moving window to detect local maxima. |
minTreeAlt |
Height threshold (m) below a pixel cannot be a local maximum. Local maxima values are used to define tree tops. |
