Data updating method and device for navigation electronic map

Abstract

The invention provides a data updating method and device for a navigation electronic map. The data updating method comprises the following steps of: acquiring updating data different from original data; constructing the updating data into a same-name derivative table with the same table structure as the original data tablet, wherein the original data table is an intermediate data format; compiling a final data format according to the original data table with the intermediate data format and the same-name derivative table. The data updating method provided by the invention has the advantages that the attribute data of the navigation electronic map is quickly updated by utilizing the method of the same-name derivative table with the same table structure to convert the navigation electronic map between the intermediate data format and the final data compilation, the data freshness of important elements or attributes or in-time correction for the problems importantly focused by customers is guaranteed to greatest extent, the data freshness and the customer satisfaction degree are improved, the customer experience is deeply optimized and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the field of navigation electronic maps, in particular to a method and device for updating navigation electronic map data. Background technique [0002] With the development and expansion of the automobile market, navigation systems have increasingly entered the automobile industry. For the navigation system, the navigation electronic map data used for navigation is an important part of it. Such as figure 1 As shown, the production cycle of traditional navigation electronic map data includes at least: product design, production planning resource organization, data collection in the field, production of navigation database in the office, comprehensive inspection of data logic, conversion of intermediate data formats, compilation of final data formats, and product Main processes such as test verification. Traditional navigation electronic map products have many production processes, long update cycles, and poor data freshness,...

AI Technical Summary

Problems solved by technology

[0004] The existing technology provides several methods to solve the problem of rapid update of navigation electronic map data. Among them, the mainstream method is to take the entire production cycle of navigation electronic map data as the research object, and design a relatively complete navigation data collection from the field to the navigator. The overall rapid update system for terminal update, this research method is more complicated in technology and higher in implementation cost
