1. A method of object mapping in a multi-dimensional dataset, said method comprising the steps of: carrying out a segmentation of the multi-dimensional dataset using multi-dimensional graphic objects ( 23 a , 23 b , 25 a , 25 b , 31 ); defining a set of geometric relations between a set of geometric templates ( 22 a , 22 b , 26 , 32 , 34 , 35 ) using a geometrical relational application framework macro ( 12 ); associating the multi-dimensional graphic objects with the geometric templates.
