1. A method for capturing information from a hexagonal grid of data sampling elements, the data sampling elements arranged such that each data sampling element is centered on a point of the hexagonal grid, comprising the step of electronically capturing the addresses of the data sampling elements as a set of two interleaved rectangular arrays, wherein each array element comprises three coordinates: (a) a first coordinate representing which rectangular array, determined as every other grid row of data sampling elements; (b) a second coordinate representing the row of the data sampling element relative to its array; (c) a third coordinate representing the column of the data sampling element relative to its array; (d) where each first coordinate is represented as a, each second coordinate is represented as r, and each third coordinate is represented as c; and, (e) converting captured array elements to corresponding Cartesian array elements having first and second rectangular coordinates x and y, comprising the step of performing a matrix multiplication of captured array elements as: [ x y ] = [ a 2 + c ( 3 ) ) ⁢ ( a 2 + r ) ] .
