classify_grid_water: Create the DEGURBA grid cell classification of water cells

Description

classify_grid_water() has been renamed to DoU_classify_grid_water() to create a more consistent API and to better indicate that this function is specifically designed to classify water in the context of the DEGURBA classification.

Usage

classify_grid_water(
  data,
  classification = NULL,
  water_land_threshold = 0.5,
  water_pop_threshold = 0,
  water_built_threshold = 0,
  value = 0,
  allow_overwrite = c(1)
)

Value

SpatRaster with the grid cell classification of water cells

Arguments

data: path to the directory with the data, or named list with the data as returned by function DoU_preprocess_grid()
classification: SpatRaster. A grid to which the classification of water cells will be added. The grid can already contain the classification or urban centres, urban clusters and rural grid cell, but this is not mandatory. Note that the grid will be adapted in-place.
water_land_threshold: numeric. Maximum proportion of permanent land allowed in a water cell
water_pop_threshold: numeric. Maximum population size allowed in a water cell
water_built_threshold: numeric. Maximum built-up area allowed in a water cell
value: integer. Value assigned to water cells in the resulting grid
allow_overwrite: vector. Values in classification that can be overwritten by water cells. By default, the classification of rural cells (1) can be overwritten, but the classification of urban clusters (2) and urban centres (3) cannot.
