From an analytic standpoint this is a straight-forward intersection operation between the point cloud, its attributes and a raster or vector grid. "An alpha-**magic** **square** is a math puzzle in which the numbers of letters needed to spell the numbers also form a **magic** **square** so that the array above adds to a constant sum of 216 on any row, column, or diagonal AND the numbers of Cyrillic letters needed to spell the Russian names of the numbers in this array, or precisely 15, 9, 12 / 9, 12, 15 / 12, 15, 9, also adds to a constant sum (36. **3x3 Magic Square FORMULA** 4 9 1 Y + 1 X 2 Y - X 3 5 7 X Y 2Y - X 8 1 6 Y + X 1 Y - 1 A) **Formula** for **3x3 magic square** which can be expanded to larger **magic square**s. 1 This relationship can be expanded into larger order **magic**.

**3x3**

**magic**

**square**puzzles is solved by determining the values that make the sums all rows, columns and diagonals equal to the same value. The sum is referred to as the
