Details
The BNG is structured using a hierarchical system of grid squares at various resolutions. At its highest level, the grid is divided into 100 km by 100 km squares, each of which is identified by a two-letter code. Successive levels of resolution further subdivide the grid squares into finer detail, down to individual 1-meter squares.
Value
A vector of type BNGReference
