Problems solved by technology

The local map in the autonomous navigation system needs to be updated regularly, and it is often possible that the navigation effect is not ideal due to changes in road and traffic conditions
The network-based mobile phone navigation method can realize real-time downloading of maps and real-time navigation. This method needs to be connected to the navigation center, and the user needs to pay a certain service fee

Embodiment Construction

[0055] A method for displaying vector map data in mobile phone network navigation of the present invention comprises the following steps:

[0056] Step 1. Interactive confirmation of mathematical elements in the vector map

[0057]The display of a navigation map is based on the mathematical elements of the map such as scale, coordinate system, and map orientation. The mobile terminal confirms these elements by interacting with the network navigation center. The mobile terminal uploads related data such as screen size to the navigation center through the data transmission channel of the wireless communication network (such as GPRS), and the navigation center determines the optimal display scale of the terminal map. At the same time, the coordinate system and map direction displayed by the terminal navigation map are also determined by the navigation center. The navigation center will send the determined mathematical element parameters to the mobile terminal.

Abstract

The invention discloses a method for displaying vector map data in mobile phone network navigation. Through interactive confirmation for mathematic elements in a vector map, download and dynamic cache processing of the vector map data, processing of geographic elements in the vector map data, processing of finishing elements in the vector map data, display and update of vehicle position information in the vector map, a user can switch a general diagram navigation mode and a detailed diagram navigation mode during navigation to achieve the effects of friendly navigation interface display, rich navigation information, reasonable map element distribution and little required data amount.

Description

technical field [0001] The invention relates to a method for displaying vector map data in mobile phone network navigation. technical background [0002] At present, there are two common mobile phone navigation systems, one is the mobile phone autonomous navigation system, the product has a GPS receiver, stores electronic maps and navigation software, the user only needs to input or select the destination name, and the device will calculate The best route is displayed on the electronic map for user reference; the other is the mobile network navigation system, which also has a GPS receiver. When navigation services are needed, the mobile terminal sends relevant information such as the destination to the navigation system. Center, the server in the navigation center calculates the best route, and downloads the navigation route and map to the mobile terminal in real time. [0003] The display of a map is an important part of a navigation system, which forms the basis of the hu...
