Abstract

The invention provides a method and a device for verifying data of an electronic map, relates to the field of an electronic map and aims to solve the technical problem that in the prior art, after the electronic map is converted into a database format from a file format, a converted database is not verified. The method comprises the following steps of acquiring a data file of one electronic map and a target database of the electronic map; acquiring a first number of first geographic elements in the data file of the electronic map; acquiring a second number of second geographic elements in the database of the electronic map; corresponding the second geographic elements to the first geographic elements; comparing the first number with the second number and generating a first comparison result; according to the first comparison result, verifying the target database of the electronic map. According to the invention, whether the number of the geographic elements of the electronic map has omission after the electronic map is converted into the database format from the file format can be verified.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a method and device for verifying electronic map data. Background technique [0002] With the wide application of database technology, the navigation electronic map has gradually developed from the traditional file storage structure to the database structure, and has increasingly become the mainstream mode of data management. This mode change brings about large-scale migration and conversion of existing map results, which in turn raises concerns about the following issue: how to verify the correctness of data before and after conversion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electronic map data verification method and an electronic map data verification device, which can verify the correctness of the data before and after the conversion of the electronic map from a file format to a database format. [0004...
