The decimal places property of the geo-spatial index identifies the number of implied decimal places for the longitudinal minimum coordinate, latitudinal minimum coordinate, longitudinal cell distance and the latitudinal cell distance. For any geo-spatial grid this value must be nonzero.

Example

A geo-spatial grid is being defined for the U.S.. The southwest corner of the grid is 25 degrees latitude and -125.5 degrees longitude. Each cell within the grid is .025 degrees by .025 degrees. There are 1000 cells within each vertical column, and 2400 cells within each horizontal row. This puts the northeast corner of the grid at 50 degrees latitude and -65.5 degrees longitude.

The geo-spatial index properties would be defined as the following:
