Get Spatial Window from Grid Catalogue

Description

Retrieves the spatial bounding box for a given spatial unit ID from the project’s spatial grid CSV catalogue.

Usage

get_spatial_window(scale_id, file = here::here("Data/Input/spatial_grid.csv"))

Arguments

scale_id

A single character string identifying the spatial unit. Must match exactly one row in the catalogue file.

file

Path to the spatial grid CSV file. Default: ‘here::here("Data/Input/spatial_grid.csv")’.

Details

Reads the CSV using ‘readr::read_csv’, filters to the row whose ‘scale_id’ column matches the supplied ‘scale_id’ argument, and constructs the bounding box vectors. Validation ensures the file is readable, has a ‘.csv’ extension, and that exactly one row matches the requested ‘scale_id’.

Value

A named list with two elements:

‘x_lim’: Numeric vector of length 2: ‘c(x_min, x_max)’.
‘y_lim’: Numeric vector of length 2: ‘c(y_min, y_max)’.
