For interactive operation between different enterprises or organizations,
it is necessary to provide high-quality map information by not only
displaying the results of retrieval from the map information servers of
those organizations in a superimposed manner but also performing
distributed retrieval on the basis of a relationship matched in sense
between the servers. Thus, an interface is provided in which the optimum
relationships between objects provided from the map servers distributed
on the Internet environment and objects defined by a desired application
are generated and a work of confirmation and modification by a user can
easily be done. Thereby, a cost required for a complicated relating
procedure indispensable to an interactive operating system is reduced.
