Map inquiry data updating method and system and server

Abstract

The invention provides a map inquiry data updating method and system and a server. The map inquiry data updating method includes the steps that description of the previous updated map data package is added into map data updated each time so that the map data is related with the previous map data package; the updated map data is packaged into an independent updated package, and the updated package and the original map data package are stored together; when a map inquiry request is received, the original map data package and the updated package are sequentially inquired according to the map inquiry request to obtain at least two corresponding inquiry results; the obtained inquiry results are sorted and then output. When the map data is updated each time, one updated data package is added individually instead of changing the original map data package, the updated data package is at the same level as the previous data package, the updating data size is small, and the problem that it takes much time to update the electronic map data in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method, system and server for updating map query data. Background technique [0002] The car machine is the common name of the car multimedia terminal, which is usually installed on the center console of the car. The map data is stored inside the car, so it can provide users with route navigation and other services, which greatly facilitates people's daily travel. Wherein, the map data includes base map data, interest point data and navigation data. The navigation data includes road information and is data necessary for route navigation. The base map data and point-of-interest data are additional information on the road, such as hotels and gas stations on the electronic map. This part of the data can provide users with more comprehensive and better route services. [0003] As the update speed of the traffic road network is accelerating, in order to better plan routes...
