1. A mapping system for mapping a target, the system comprising: (a) at least two markers adapted to be differently positioned with respect to a target mass being mapped, said at least two markers comprising: (i) at least one external marker adapted for positioning outside the target mass and defining a target context that indicates a target position and orientation with respect to a surrounding area around said target mass, and (ii) at least one target marker adapted for fixed positioning on the target mass, within the target mass, or at a fixed spatial relationship with respect to the target mass; (b) a data acquisition module configured to provide data indicative of measured position coordinates for at least one data point at said target mass; and (c) a registration module connected to the data acquisition module and adapted to (i) receive said data indicative of the position coordinates for the at least one data point; (ii) determine, by utilizing position data of the at least one target marker relative to the at least one external marker, position coordinates of said at least one data point relative to at least a portion of said target context; and (iii) generate output data indicative of a location relative to said surrounding area, said location matching said data point at said target mass and being different therefrom.
