First Claim
1. A system of displaying map images allowing a user terminal to display a map image on the basis of map data transmitted from a map database site through a computer network, comprising:
- a map information database provided in said map database site for accumulating the map data constructed of units for displaying map images each with a display range smaller than a display range of a map image corresponding to one page displayed on a user terminal, in association with position data indicating the display ranges of the individual map images; and
map-image display means provided in said user terminal for combining the map data of a plurality of units with each other on the basis of the position data of the map data, which are read out from the map information database provided in the map database site and transmitted from the map database site, to form the map image corresponding to one page for display.

Abstract
A map database site S comprises a map information database Sb for accumulating the map data constructed of units for displaying of unit images m each having a display range smaller than a display range of a map image M corresponding to one page of a map image displayed on a user terminal T, in association with position data indicating the display ranges of the individual unit images m. A user terminal T comprises map-image display means for combining the map data of a plurality of units with each other on the basis of the associated position data, which are read out from the map information database Sb provided in the map database site S and transmitted from the map database site S, to form the one-page map image M for display.
