Map data quality freshness obtaining method and device and storage medium

Abstract

The invention provides a map data quality freshness obtaining method and device and a storage medium. The method comprises the steps of obtaining social development average data corresponding to eachcity scale type in a target area; obtaining a key element region density average value of each city scale type in the target region and a key element region density value corresponding to each city; and obtaining an electronic map data quality freshness analysis result according to the key element region density value corresponding to each city, the key element region density average value corresponding to the city scale type to which the city belongs, the social development data of each city and the social development average data corresponding to the city scale type to which the city belongs. The cities with the social development data and the key elements in positive correlation are determined as the cities with the electronic map data quality freshness reaching the standard, and the cities with the social development data and the key elements in negative correlation are determined as the cities with the electronic map data quality freshness attenuated, so that the accuracy of an electronic map data quality freshness analysis result is improved.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to a method, device and storage medium for acquiring map data quality and freshness. Background technique [0002] With the continuous development of geographic information technology, people have more and more demands for electronic map services, for example, using electronic maps for navigation and positioning. Due to the rapid development of the city, the information of various urban surface features changes very frequently. Therefore, in the process of using the electronic map, the electronic map service provider needs to update the electronic map data quickly to ensure that the electronic map data is consistent with the urban surface. The difference of object information is the smallest. At present, electronic map service providers mostly judge whether to update by monitoring the quality and freshness of electronic map data. [0003] In the prior art, t...

Problems solved by technology

[0004] However, the quality and freshness of map data obtained based on user feedback data is not comprehensive enough, and the use of on-site measurement to obtain the quality and freshness of map data requires more resource investment and higher costs
