· Locator Grid
· Reference/Index Grid
1This grid has 172 complete square cells and each cell is identified by an 8 bit base 2 binary number symbol representation. 0 is represented by a short rounded pillar. There is no zero cell. The first cell located at top left is binary 1, digit 1 is represented by a long pillar at the extreme right position on the bottom horizontal line of cell one: each individual subsequent cell is then easily identified. Lines/Inch ~150.
2 Thick bars dividing regions into 6 thin bar areas, which are identified by a numeric system. 3 Thick bars dividing regions into 9 thin bar areas, which are identified by alphabetical letters located in the center of the grid. 4 Each of the 322 grids squares, can be identified by reference to its unique combination of base 2 binary number and alphabet symbol (A-T). 0 is a short rounded solid pillar and 1 is a longer rounded solid pillar. 5 The block of 625 (25 x 25) individual cells is divided into smaller blocks bounded by thicker crenellated bars. Each small block of 25 cells has a central alphabet letter from A to Y for identification purposes. 6 The block of 1152 (32 x 36) individual cells is divided into smaller blocks bounded by thicker crenellated bars. Each small block of 36 (6 x 6) cells has a central number from 1 to 32 for identification purposes.
