NSW Blocks and Units Graticule
Map blocks and map units are based on a system originally devised by the British
Ordinance Survey. Each 1:1 million scale map sheet is subdivided into 3456
graticular map blocks, each measuring 5’ of latitude by 5’ of longitude. These map
blocks are further subdivided into 25 1’ by 1’ map units. A map unit is approximately
3 square kilometres in size.
Map blocks and map units are used in New South Wales to define certain types of
titles. Petroleum exploration titles (PELs) are applied for and granted as a series of
map blocks (Map sheet, block number), and mineral exploration titles, which tend to
be smaller in size, are defined as a list of map units.
