Create a Deterministic Reference Grid

Generates a regular square or hexagonal spatial grid over a study area bounding box and assigns each cell a stable unique identifier. Create the grid once and reuse it across pipeline runs so that cell_id values remain consistent over time.

Usage

create_reference_grid(study_area_bbox, cell_size_meters = 500, hex = TRUE)

Arguments

study_area_bbox

An sf polygon or bounding box defining the spatial extent of the grid.

cell_size_meters

Numeric. Grid cell size in metres. Default is 500.

hex

Logical. If TRUE (default), creates hexagonal cells; if FALSE, creates square cells.

Value

An sf polygon object with a cell_id column containing a unique identifier for each cell (format: "GRID_<n>").
