METHOD AND SYSTEM FOR OVERLAYING LANDMARK INFORMATION ON A GEOCODED GRAPHIC
First Claim
1. A method for generating enhanced map data, the method comprising:
- generating a geocoded graphic of an area using a map portal, the geocoded graphic including at least a recommended route for reaching a destination point within the area;
transforming a set of landmark-based information for the recommended route into a corresponding set of icons, wherein the landmark-based information describes the type and location of a plurality of traffic control devices along the recommended route;
overlaying the icons onto the geocoded graphic to thereby generate a graphic portion of the enhanced map data; and
displaying at least the graphic portion of the enhanced map graphic on a computer display.

Abstract
A method for generating enhanced map data includes generating a geocoded graphic of an area using a map portal, the graphic including a recommended route, and then transforming landmark data including traffic control device information for the route into representative icons. The icons are overlaid onto the route to form at least part of the enhanced map data, which is displayed on a computer display. A data server in communication with at least one information source and a computer device having a display screen includes a central processing unit (CPU) and an algorithm executable by the CPU. Execution of the algorithm generates the enhanced map data using information from the information source, and automatically displays the enhanced map graphic on the display screen of the computer device. The icons can also be embedded within text-based driving directions that are generated as another part of the enhanced map data.

6. A method for generating enhanced map data, the method comprising:
-
recording a starting point and a destination point in a memory location of a data server; generating a geocoded map of the destination point and an area surrounding the destination point, the geocoded map including at least a recommended route suitable for reaching the destination point from the starting point; processing a set of landmark information for the area, wherein the set of landmark information describes the locations of a plurality of traffic control devices that are located along the recommended route; transforming the landmark information into a corresponding set of icons each graphically representing one of the traffic control devices; overlaying the icons onto the recommended route of the geocoded graphic to thereby generate a graphic portion of the enhanced map data; and displaying at least the graphic portion of the enhanced map data on a computer display that is located remotely from the data server. - View Dependent Claims (7, 8, 9, 10, 11)

12. A data server in communication with at least one external information source and a computer device having a display screen, the data server comprising:
-
a central processing unit (CPU); and an algorithm executable by the CPU and adapted for generating enhanced map data using information from the at least one information source, and for automatically displaying the enhanced map data on the display screen of the computer device; wherein the enhanced map data includes at least a geocoded map having a recommended route between a starting point and a destination point, and a plurality of landmark-based icons that are overlaid on the geocoded map along the recommended route, the plurality of landmark-based icons including at least one of a traffic signal icon and a stop sign icon. - View Dependent Claims (13, 14, 15)
