Create Indigenous Managed Lands Raster (LANDMark + ICCA)

make_indigenous_managed_lands.Rd

This function identifies Indigenous- and community-managed lands using two datasets: the LANDMark dataset and the ICCA Registry. It buffers point geometries if required, merges both sources, calculates fractional coverage over planning units, applies a threshold, and returns a binary raster indicating areas likely under Indigenous management.

Usage

make_indigenous_managed_lands(
  sf_landmark = NULL,
  sf_icca = NULL,
  iso3,
  pus,
  buffer_points = TRUE,
  output_path = NULL
)

Arguments

sf_landmark

sf or NULL. LANDMark Indigenous lands dataset, subset to the country of interest.

sf_icca

sf or NULL. ICCA Registry dataset, subset to the country of interest.

iso3

Character. ISO3 country code for naming.

pus

SpatRaster. Planning unit raster for alignment and coverage calculations.

buffer_points

Logical. Buffer POINT/MULTIPOINT geometries into polygons (default = TRUE).

output_path

Character or NULL. If provided, saves output raster as a COG to this directory.

Value

A binary SpatRaster where:

  • 1 = likely Indigenous-managed

  • 0 = not Indigenous-managed

Examples

if (FALSE) { # \dontrun{
indigenous_lands <- make_indigenous_managed_lands(
  sf_landmark = landmark_sf,
  sf_icca = icca_sf,
  iso3 = "COL",
  pus = planning_units,
  output_path = "outputs/"
)
terra::plot(indigenous_lands)
} # }
