Calculate restore and urban green zone budgets as percentages — calculate_restore_and_urban

This function calculates the budget for restore and urban green zones as a percentage of the total planning unit (PU) area for a specified country.

Uso

calculate_restore_and_urban_budgets(
  iso3,
  workspace_dir = NULL,
  coverage_fraction = 0.3,
  pu_raster = "planning_units.tif",
  restore_zone_raster = "restore_zone_v1.tif",
  urban_areas_raster = "urban_areas.tif"
)

Argumentos

iso3: A 3-letter ISO3 country code (e.g., "MWI"). Used only for reference.
workspace_dir: Path to the directory containing all raster inputs (not hardcoded by ISO3).
coverage_fraction: Fraction of zone coverage to use as budget (default: 0.3).
pu_raster: Filename of the planning unit raster (within workspace_dir). Default: "planning_units.tif".
restore_zone_raster: Filename of the restore zone raster (within workspace_dir). Default: "restore_zone_v1.tif".
urban_areas_raster: Filename of the urban areas raster (within workspace_dir). Default: "urban_areas.tif".

Valor

A named numeric vector with two elements: restore_budget_pct and urban_green_budget_pct, each representing the budget as a percentage of the total PU area.

Detalhes

The restore zone typically represents degraded areas, and the urban green zone typically represents mapped urban areas. Each budget is calculated as a fixed fraction (default 30%) of the coverage of its respective zone over the PU layer.

This function assumes input rasters are co-aligned and represent valid binary zone masks.

Exemplos

if (FALSE) { # \dontrun{
calculate_restore_and_urban_budgets("MWI", workspace_dir = "/path/to/my-data/az_uploads")
} # }
