Abstract

The invention discloses a navigation path downloading method, a navigation path downloading server and a position service terminal. The method comprises the following steps of: uploading current position information and communicating with a navigation path downloading server, so that the navigation path downloading server determines destination information; receiving planned path information of at least one planned path, wherein the at least one planned path is obtained by calculation by the navigation path downloading server according to the current position information, the destination information and data of an electronic map stored in the navigation path downloading server, and the planned path information at least comprises position information of a plurality of points on the plannedpath; and matching the planned path information with the data of the locally stored electronic map so as to display the planned path on the electronic map. By the navigation path downloading method and the navigation path downloading server, the accurate position of any required point of interest or the most time-saving and economic navigation path is provided for the position service terminal; meanwhile, the data of the electronic map can be supplied without an extremely large storage space and high network flow; therefore, the cost is saved and the navigation efficiency is improved.

Description

Technical field [0001] The present invention relates to location service technology, in particular to a navigation path download method, server and location service terminal. Background technique [0002] The location service terminal refers to a device with location service function and related functions. The location service terminal takes a navigation device as an example. Its working principle is that the navigation device determines the location coordinates of a specific location, and matches it with the location coordinates recorded in the electronic map stored by itself, so as to determine the navigation object carrying the navigation device. The accurate location on the electronic map. The navigation device can be a vehicle-mounted terminal, a portable navigator, a mobile phone terminal, and so on. Navigation objects can be vehicles, pedestrians, etc. After the user sets the departure place and destination, the navigation device will calculate the navigation path and n...
