A method (40) for parameterizing a predetermined geographic area (12) serviced by a satellite communication system (60) into a number of equally shaped sub-partitions (22) is discloseed. The satellite communication system (60) has a processor (64, 72)for generating data elements and a memory (66, 74) for storing the data elements in data structure. The method (40) includes the step (42) of determining a total latitude side length dimension and a total longitude side length dimension of the predetermined geographic area (12) from latitude and longitude values representative of the geographic area. The steps (44) also include determining the area of a sub-partition based upon the total latitude side length, the total longitude side length, and the number of equally shaped sub-partitions. Each of the sub-partitions (22) are substantially square and have the same area. The steps also include determining (50) an actual side latitude dimension (26) of the sub-partition (22) and storing the side latitude dimension (26) in the data structure, and determining (52) an actual side longitude dimension (28) of the sub-partition (22) and storing the side longitude dimension (26) in the data structure. The satellite communication system (60) generates a grid from the actual side latitude dimension (26) and the actual side longitude dimension (28) and superimposes the grid over the predetermined geographic area (12).
