Navigation system utilizing XML/SVG map data converted from geographic map data and layered structure of XML/SVG map data based on administrative regions
First Claim
1. A navigation system for guiding a user to a destination, comprising:
- a map data storage for storing XML (extensible markup language) and/or SVG (scalable vector graphics) format map data converted from geographic data available in the market;
a controller for controlling an overall operation of determining types of requested data for the navigation system either text data or image data and retrieves XML format map data when the requested data is text data and retrieves SVG format map data when the requested data is image data; and
a display controlled by the controller for interfacing with the user and displaying the text data and/or image data.

Abstract
A navigation system uses XML/SVG format map data for achieving flexibility in modifying the map data. A method of converting geographic data into the XML/SVG format map data includes the steps of retrieving the geographic data, analyzing the retrieved geographic data for its data elements structure, data type and semantics, and converting the analyzed data to the XML/SVG format map data for with the navigation system. The XML/SVG format map data is constructed in a layered structure created based on administrative regions such as states, counties and cities. The XML/SVG format map data can be delivered to a remote user as a unit of administrative region through a communication network.
