There is provided a tie-in device for correlating at least two different coordinate systems. The tie-in device comprises an outer surface having a predefined geometric shape, such as a generally spherical surface, located at a first predefined distance from a reference point of the tie-in device, such as the center of the generally spherical surface. The outer surface of the tie-in device is mappable to determine the location of the reference point in a first coordinate system. The tie-in device comprises at least one target located at a second predefined distance from the reference point. The target is locatable in a second coordinate system to determine a location of the reference point in a second coordinate system. The relative locations of the reference point are tied-in, advantageously by processing circuitry, to correlate the first and second coordinate systems.
