Package: FIAstemmap
Title: Stand structure analysis of US national forest inventory plots

Description: Maps individual tree stem locations on field plots of the Forest
Inventory and Analysis (FIA) Program of USDA Forest Service. Stem locations
are mapped in cartesian coordinate space based on distance and azimuth
offsets from subplot and microplot centers. Per-tree crown widths are
estimated using a set of allometric equations with coverage for the
conterminous US, and provided as an optional output. 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. Provides facilities for exploratory data analysis and integration
with the 'spatstat' library.
