Map BNG References to Spatial Objects

Description

Generate a spatial data frame of BNG references and grid square geometries.

Usage

bng_grid_100km(xmin, ymin, xmax, ymax, ...)

bng_grid_50km(xmin, ymin, xmax, ymax, ...)

bng_grid_10km(xmin, ymin, xmax, ymax, ...)

bng_grid_5km(xmin, ymin, xmax, ymax, ...)

bng_grid_1km(xmin, ymin, xmax, ymax, ...)

Arguments

xmin, ymin, xmax, ymax

Optional bounding box coordinates.

...

Additional arguments. Not currently used.

Details

These convenience functions generate a spatial data frame of BNG references and grid square geometries at pre-determined resolutions. This function combines bbox_to_bng() and bng_to_grid_geom() into a data frame. Optionally, the grid can be for a defined bounding box area of interest. If the bounding box is omitted, then all grid squares within the valid bounds of the BNG are returned.

Only selected resolutions are provided to avoid excessively large data frames. For additional spatial data files of all resolutions, please see the osbng-grids GitHub repo.

The sf package is required for this function.

Value

Data frame object of type sf with the grid reference as a BNGReference object and the grid square polygon geometry.
