The present invention provides a method, device and storage medium for acquiring map data quality and freshness. The method includes: acquiring the average social development data corresponding to each city scale type in the target area; acquiring the key element area density of each city scale type in the target area The average value and the regional density value of key elements corresponding to each city; according to the regional density value of key elements corresponding to each city and the average value of regional density of key elements corresponding to the type of city size to which the city belongs, the social development data of each city and the size of the city to which the city belongs The average social development data corresponding to the type, and obtain the analysis results of the quality and freshness of the electronic map data. By identifying cities with a positive correlation between social development data and key elements as cities with up-to-standard electronic map data quality freshness, and cities with negative correlations between social development data and key elements as cities with attenuated electronic map data quality, we can improve the quality of electronic map data. Accuracy of map data quality freshness analysis results.
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...
