Converts OS Grid Reference to BNG/WGS coordinates.

Source: R/osg_parse.R

This function converts an Ordnance Survey (OS) grid reference to easting/northing or latitude/longitude coordinates.

osg_parse(grid_refs, coord_system = c("BNG", "WGS84"))

Arguments

grid_refs

This is a string (or a character vector) that contains the OS grid Reference.
coord_system

By default, this is "BNG" which stands for British National Grids. The other option is to set coord_system = "WGS84", which returns latitude/longitude coordinates (more info can be found here https://www.epsg-registry.org/).

Value

vector made of two elements: the easting and northing (by default) or latitude and longitude coordinates.
