FIAstemmap: Tree Canopy Modeling for USDA Forest Inventory and Analysis
Plots
Maps individual tree stem locations on field plots of the Forest
Inventory and Analysis Program of USDA Forest Service
(<https://research.fs.usda.gov/programs/nfi>). Stem locations are mapped in
cartesian coordinate space based on field-measured distance and azimuth from
subplot and microplot centers. Per-tree crown widths are estimated using a
curated set of allometric equations with coverage for the conterminous US.
Spatial descriptors of tree point pattern are computed at the whole plot
level. Several stand height metrics are also computed and provided in the
output. The spatial representation of modeled tree crowns is used to
generate estimates of fractional tree canopy cover at the microplot, subplot
and whole plot levels. Convenience functions are provided for efficient data
processing. Exploratory data analysis is also facilitated via integration
with the 'spatstat' packages.
