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.
