#' Strata definitions used by CERMB.
#'
#' Strata used within the Centre for Environmental Risk Management of Bushfires,
#' University of Wollongong, to rasterize LiDAR point clouds. The lowest two
#' strata are 0-0.3m and 0.3-0.5m. Subsequent strata are 0.5m intervals up to
#' 10m; then 1m intervals up to 30m; then 5m intervals up to 80m; then a
#' catch-all layer for >80m.

#' Former strata definitions used by CERMB.
#'
#' Strata formerly used within the Centre for Environmental Risk Management of
#' Bushfires, University of Wollongong, to rasterize LiDAR point clouds. These
#' have now been replaced by \code{\link{StrataCERMB}}. The lowest two strata
#' are 0-0.3m and 0.3-0.5m. Subsequent strata are 0.5m intervals up to 30m; then
#' a catch-all layer for >30m.
