#' @section USNVC overview:
#' The \href{http://usnvc}{U.S. National Vegetation Classification (NVC)} is a
#' standardized, hierarchical classification system for vegetation in the United
#' States. (It is aptly named.) The \href{https://www.fgdc.gov/standards/projects/FGDC-standards-projects/vegetation/NVCS_V2_FINAL_2008-02.pdf}{NVC standards} were developed by a partnership of agencies (e.g., USDA
#' Forest Service and US Geological Survey), professional organizations (e.g.,
#' the Ecological Society of America), and non-profits (e.g., NatureServe). The
#' full NVC database, which can be downloaded from
#' \url{http://www1.usgs.gov/csas/nvcs_data/USNVCFullDownload.zip}, contains 18
#' tables with information on 8,192 vegetation categories, ranging in scope from
#' seven very broad Classes to >4,000 highly refined Associations.
