Generating Irish Grid letterThe Irish National Grid is a coordinate reference system for Ireland. It is measured in metres with a range (0,0) to (500,000,500,000). For ease of reference a set of labelled grid squares are used. These are A to Z with no I. The code below accepts an ING coordinate and returns the grid square that contains the coordinate.
