1. A method for site calibration of a controller, the method comprising the acts of: determining coordinates of a point in a first coordinate system based on at least one measurement by a surveying device; determining coordinates of the point in a second coordinate system based on data provided by a global positioning device; calculating a transformation of the first coordinate system relative to the second coordinate system based on the coordinates determined for the point; and calibrating the controller based, at least in part, on the transformation.
