Spatial Coverage Sampling with Equal-Area Strata — ss_coverage_equal_area • soilsampling

Generates sampling points using spatial coverage with equal-area strata. Useful when strata need to have similar sizes.

Usage

ss_coverage_equal_area(
  x,
  n_strata,
  n_try = 1L,
  n_cells = 2500L,
  verbose = FALSE
)

Arguments

x: An sf object representing the study area.
n_strata: Integer, number of strata to create.
n_try: Integer, number of random initializations (default 1).
n_cells: Integer, approximate number of grid cells (default 2500).
verbose: Logical, whether to print progress (default FALSE).

Value

An object of class ss_samples.

Details

This function creates strata of approximately equal area using the swopping algorithm, then returns centroid samples.

Examples

if (FALSE) { # \dontrun{
library(sf)
poly <- st_polygon(list(rbind(c(0, 0), c(100, 0), c(100, 50), c(0, 50), c(0, 0))))
study_area <- st_sf(geometry = st_sfc(poly))

samples <- ss_coverage_equal_area(study_area, n_strata = 25)
} # }
