Abstract: A method (100) comprises steps of: receiving a first digital model (102) of a first three-dimensional scene comprising at least one object; receiving a second digital model (112) of a second three-dimensional scene comprising at least one object; and performing a change analysis (102) on the first and second digital models to provide a difference indication representing a difference between the first and second models.

In another embodiment, a conflation operation is performed on the difference model provided by the change analysis (120) and an object level change database (124) is produced.
