Claim One:
1. A method comprising: identifying an object in a source graph, the object being identified by a directed way and an offset there along; defining a closure graph around the object in the source graph, the closure graph comprising at least one vertex; building at least one closure set based on the closure graph, the closure set comprising at least one path having either a start node or end node of the directed way at a first end of the path and an anchor node at a second end of the path, the second end being opposite the first end, wherein an anchor node is a junction that is tagged with a junction identifier, the junction identifier configured to uniquely identify the junction in both the source graph and a target graph; identifying the anchor nodes of the closure set on the target graph, the identifying based at least in part on the junction identifier associated with the anchor node; and deflating the closure set on the target graph to identify a target object in the target graph that corresponds to the object in the source graph.
