Create Indigenous Managed Lands Raster (LANDMark + ICCA) — make_indigenous_managed

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.

Utilisation

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.

Valeur de retour

A binary SpatRaster where:

1 = likely Indigenous-managed
0 = not Indigenous-managed
