A user can access a common database from a remote communications port, at
any qualified location, to generate a map or other positional information
which locates selected items of interest, e.g., businesses, stores,
architectural sites, and the like. The database contains information
representing the items of interest, including, for each of the items of
interest, positional coordinates, a geographic vicinity, and a selected
category. The positional coordinates discretely locate the vicinity, while
the vicinity specifies the exact locations of the items of interest in the
selected category. For example, a user in New York can select the display
of sporting shops in the area surrounding Chicago O'Hara International
Airport selectively. A user can also access a port and display locations
of items of interest within the same vicinity as the user and relative to
the user's position. The database can be modified from qualified remote
locations to change, or add to, the information therein. An advertisement
can be tagged to the display or print out as an association with the
selected items of interest.
