Product data generator, generating method, and navigation system

Abstract

The invention discloses a product data generator, a generating method, and a navigation system. The generator includes: a data loading module, used to load a file directory template file and a data column name description file; a file generating engine, used to File and data column name description file, call the relevant data processing interface in the file generation engine to process the pre-loaded initial navigation data, and generate the navigation data file; the file encoding module is used to convert the navigation data file according to the preset encoding parameters Converting to a specified encoding format; the file distribution module is used to distribute the encoded navigation data files to the corresponding product directory structure according to the specified data specification, and generate a navigation data product of the specified specification. The present invention can meet the requirements of different customers for data specifications by changing the file directory template file and the data listing description file, avoids changing the core code, and improves the efficiency of product generation.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a product data generator, a generating method and a navigation system. Background technique [0002] In the field of electronic maps, different enterprise customers have not formed a unified requirement for data specifications, and each enterprise customer may have its own requirements, such as the specifications of electronic map data built into the vehicles sold by different car manufacturers It may be different. Car manufacturer A requires the Chinese names of all data to be placed in one file, while car manufacturer B requires different types of Chinese names to be stored in different files. [0003] In addition, different enterprise customers may have inconsistent file names and field names for data storage such as roads, points of interest (POI), connectivity relations, and background. Therefore, the needs of enterprise customers make map providers need to develop separately...

AI Technical Summary

Problems solved by technology

Therefore, the needs of enterprise customers make map providers need to develop separately for customer-specific data specifications when providing data for different enterprise customers, by writing programs separately, and hard-coding the names and field definitions of data specification files into the program, however, this leads to the need to modify the core code when the requirements change, the efficiency of product generation is low, and the reusability of the program is also low
