DYNAMIC LOCATION-BASED MAPPING SYSTEM AND METHOD
First Claim
1. A graphical mapping system configured to display mapping information on a handheld device, said system comprising:
- an image map database configured to store map data for a plurality of geographic areas, said map data being useful for generating graphical maps;
a vector map database configured to store vector map data, said vector map data being useful for generating vector “
overlays”
that correspond to said graphical maps; and
wherein a set of image mapping data and a corresponding set of vector mapping data, both associated with a given geographic location, are retrievable in response to a mapping request from the handheld device.

Abstract
A graphical mapping system configured to display mapping information on a handheld device is disclosed. The system includes an image map database configured to store map data for a plurality of geographic areas, which is useful for generating graphical maps. The system further includes a vector map database configured to store vector map data, which is useful for generating vector “overlays” that correspond to the graphical maps. In response to a mapping request from a handheld device, a set of image mapping data and a corresponding set of vector mapping data, both associated with a given geographic location, are retrievable.

19. A method of displaying mapping information on a display screen of a handheld device, comprising the steps:
-
sending a mapping request to a location-based mapping system; receiving an image map data set and a vector map data set from said mapping system; and generating a static map image on the display screen based upon said image map data set, wherein information from said vector map data set is correlated to, but not displayed on, said static map image. - View Dependent Claims (20, 21, 22)

23. A handheld device for displaying a graphical map, comprising:
-
a display screen; software configured to receive a set of image map data and a set of vector map data, said software being further configured to generate a static map image on said display screen from said image map data and to selectively display data from said vector map data set corresponding to a given location on said static map image. - View Dependent Claims (24, 25)
