Claims

A map display device that displays a current position together with a map,
For a plurality of types of features, a data acquisition unit for acquiring map data in which graphic data representing the position and shape of the features and attribute information representing the types of the features are recorded in association with each other;
A detection unit for sequentially detecting the current position;
A search unit that searches the map data based on the current position, the graphic data, and the attribute information for a feature that can be included in the current position as a reference for drawing the current position detected by the detection unit ;
Wherein with drawing the feature represented by the graphic data, map display device and a drawing unit for drawing a display of current position in a predetermined position on the features that have been searched by the searching unit.

The map display device according to claim 1,
Furthermore, a determination unit for determining the type of moving means of the user of the map display device ,
The map display device, wherein the search unit specifies a type of a feature to be searched according to a type of moving means determined by the determination unit.

The map display device according to claim 1 or 2 , wherein
The drawing unit, when the attribute information associated with the retrieved feature by the searching unit represents buildings, the position of the center of the該建product as a predetermined position, rendering the display of the current position Map display device.

A map display device according to any one of claims 1 to 3,
