Interpretation

1.  In this Schedule—

“editable” (“y gellir eu golygu”) means in a format that allows (without the need for manipulation) the electronic production of—

spatially referenced to the British National Grid reference system used by the Ordnance Survey as a pair of integers to show Eastings then Northings in metres from the origin, and

(c)

aligned with the 10 metre vertices of the British National Grid reference system used by the Ordnance Survey so that references finish with the number zero.
