A method for customizing a local map with a grid that can be rotated and zoomed includes the steps of (a) defining a grid on a map; (b) generating a grid set-up data as a function the defined grid; and (c) employing a computer based device in a manner to receive the grid set-up data and convert a geographical coordinate to a local coordinate on the map. A device for such use includes a computer based device having a processor, a memory operably association with the processor, a power source, means for receiving a geographical coordinate; and geographical coordinate conversion software operably disposed in the memory and operably associated with the processor in a manner to in a manner to receive grid set-up data and convert the received geographical coordinate to a local coordinate on the map.
