Grid references are 34T FN, four figures east and four figures north, locating a 10 m square, same as the printed sheet. Grid lines are 1 km; they thin out to 100 m as you zoom in. Magnetic bearings use the sheet declination of 5.99° E. The border and the five no-play structures are traced from the printed sheet and are good to roughly 10 m. Each no-play box is squared to the grid, so it covers a little more ground than the building itself. It is a planning aid, not a marshal. Tiles come from Esri, CARTO, OpenTopoMap and OpenStreetMap and need a connection, so load the page and pan over the field once before you lose signal. Serve the file over http or https, not from disk, or the tile servers refuse it.
