Inventoried Plots Data for a Stand Case Study in La Rioja

This list includes trees detected with TLS for 16 single scans corresponding to plots located in La Rioja, a region of Spain, in the north of the Iberian Peninsula (first element), as well as those inventoried in the field for these 16 plots (second element). Plot attributes related to stand stratum are also included (third element).

The elements of the list are as follows:

1. tree.tls: data frame that includes the list of trees detected with tree.detection.single.scan for 16 TLS single-scan sampling points. The following variables are provided for each tree (see tree.detection.single.scan ‘Value’ for more details):

   [,1]	id	character/numeric	[,2]
   file	character	[,3]	tree
   numeric	[,4]	x	numeric
   [,5]	y	numeric	[,6:8]
   phi, phi.left, phi.right	numeric	[,9]	h.dist
   numeric	[,10]	dbh	numeric
   [,11]	h	numeric	[,12]
   v	numeric	[,13:16]	n.pts, n.pts.red, n.pts.est, n.pts.red.est
   numeric	[,15]	partial.occlusion	numeric

2. tree.list.field: data frame that includes the list of trees measured in 16 circular fixed area plots of radius 20 m, whose centres coincide with TLS single-scans points. The following variables are provided for each tree:

   [,1]	id	numeric	plot identification (coincident to TLS scans)
   [,2]	tree	numeric	trees numbering
   [,3]	Sp	numeric	specie code according to NFI ()
   [,4]	x	numeric	x cartesian coordinate
   [,5]	y	numeric	7 cartesian coordinate
   [,6]	h.dist	numeric	horizontal distance (m) from plot center to tree center
   [,7]	dbh	numeric	tree diameter (cm) at breast height (1.3 m)
   [,8]	h	numeric	tree total height (m)
   [,9]	dead	numeric	dead (1) or not (NA)
   [,10]	v.user	numeric	stem volume (m^3) estimated with allometric equations
   [,11]	w.user	numeric	stem biomass (Mg) estimated with allometric equations
