Selected plant trait indicators which may be computed using the collected dataset and provided post processing software

Acronym	Full name (unit)	Description
Height	Height (m)	Height (=Z coordinate) above the soil reference height. Negative values are ignored
NDVI	Normalized difference vegetation index (−)	Defined as $(NIR-R)/(NIR+R)$, where NIR is the near infrared (803 nm)and R is the red (670 nm) reflectance respectively [61]
HS*	Hyperspectral reflectance (−)	Hyperspectral reflectance, where *$\in \{1,\dots ,25\}$ indicates the spectral band index
EGI	Excess green index (−)	Defined as ($2G-R-B$), based on the color reflectance [62]
NEGI	Normalized excess green index (−)	EGI divided by $(R+G+B)/3$
NDRI	Normalized difference red index (−)	Defined as $(G-R)/(G+R)$, based on color values
ERI	Excess red index (−)	Defined as $1.4R-G$, based on color reflectance
HSDiff*${}^1$_*${}^2$	Difference in hyper spectral reflectance (−)	Difference in reflectance of two hyperspectral bands *${}^1$–*${}^2$, where *${}^1$, *${}^2$ $\in \{1,\dots ,25\}$ indicates the spectral bands
CanCov	Canopy cover (−)	The percentage of points labeled as plants. Canopy cover is independent of the evaluation statistic
VolEst	Volumetric estimate (m*pixels)	The integral over the height of all points. Volumetric estimate is independent of the evaluation statistic

Due to the objective oriented nature of the software suite and comprehensive spatio-temporal nature of the data provided, users of the dataset can readily implement additional indicators of interest such as multichannel vegetation indices, temporal indicators e.g rate of growth for further analysis
