Embodiment Construction

[0046] figure 1 A schematic diagram of a navigation system 100 is shown. The navigation system 100 can be implemented in various ways, for example, as a vehicle-mounted navigation system, a handheld personal navigation device (PND), in a handheld communication device such as a smartphone, or in a personal digital assistant device (PDA) or similar device navigation system.

[0047] The navigation system 100 is controlled by a processing unit 105 which operates according to control instructions stored in the memory 102 . The processing unit 105 may be implemented as a single or multiple microprocessors, digital signal processors (DSPs), application specific integrated circuits (ASICs), or similar devices. Memory 102 may include all types of memory, such as random access memory, flash memory, hard drives, or similar devices.

[0048] The processing unit 105 is adapted to retrieve map data from a map database 103 stored in the memory 102 . For this purpose, the processing unit...

Abstract

The present invention provides a navigation system comprising a display for displaying map sections and point of interest (POI) data to a user and a database which stores POI data. A retrieval unit is provided to retrieve from the database POI data for the map section to be displayed. In embodiments of the invention the POI database comprises POIs and substitute POIs representing a number of POIs in a map region. It may then depend on the map scale with which the map section is to be displayed whether a substitute POI or a POI which it represents is retrieved from the database.

Description

technical field [0001] The invention relates to a method for displaying points of interest (POI) on a display of a navigation system capable of displaying maps at different map scales, and to a corresponding navigation system. The invention further relates to a data carrier comprising a point of interest (POI) database. Background technique [0002] In recent years, the use of navigation systems, such as simple hand-held navigation devices or more complex in-vehicle systems, has increased considerably. Almost without exception, navigation devices include a display on which map information is presented to the user. A map displayed on a navigation device usually includes a graphical indication of cities and the roads connecting these cities, the size of the cities and the class of roads indicated by corresponding graphical symbols. [0003] Some conventional devices are further able to display points of interest (POIs) on such a map. Generally, the points of interest can be...
