Abstract: A method for integrating digital maps, each containing a plurality of geographical objects. A three-step integration process is presented. First, geographical objects are retrieved from maps on the Web. Secondly, pairs of objects that represent the same real-world entity, in different maps, are discovered and the information about them is combined. Finally, selected objects are presented to the user. The proposed process is efficient, accurate (i.e., the discovery of corresponding objects has high recall and precision) and it can be applied to any pair of digital maps, without requiring the existence of specific attributes.
