Full 100 Metre Reference ST 010946
The above Full Reference is unique. For many purposes the first grid letter can be omitted,
giving a reference T 010946 which recurs at intervals of 500 Kilometres. If both grid
letters are omitted, the resulting reference 010946 recurs at intervals of 100 Kilometres.
When the area concerned is sufficiently restricted, as will usually be the case with maps
on scales of one inch to the mile and larger, both the grid letters are normally omitted.
Heights are in feet above Mean Sea Level. Contours are at 50ft. intervals
True North at the West edge of this sheet is 01° 14' 50 " E of Grid North
Mag. North from Grid North is 8'A0 W. (1962) decreasing by about in six years
