MGRS
position is derived from UTM
- each UTM area is divided is squares
of 100 km by 100 km and designated by two letters (eg. 31ULS means the LS square
in the 31U area).
- are (mostly) computed in hm
(eg 31ULS240323 church of Bierbeek) [MGRS hectometric]
- but also in km (eg 31ULS2432)
[MGRS kilometric]
- or 10x km (eg 31ULS23)
- or 10x m (eg 31ULS24073235)
- or m (eg 31ULS2407232354) [MGRS
metric]
- means Military Grid
