摘要：
A method of providing geographic information for a navigation system comprises obtaining a request for a geographic region and accessing geographic data corresponding to the geographic region from a geographic database. The method also comprises providing a plurality of first map images generated from the geographic data. Each of the first map images represents a unique portion of the geographic region. When the first map images are displayed together, they provide a first map depicting the geographic region.
