Background technique

With the rapid development of the social economy, the application of electronic maps has penetrated into all aspects of our lives. The electronic map function can be set in intelligent terminals (such as mobile phones) to search and store the target location information.

In the prior art, in order to realize the search and storage of the target location information, the map area of the data to be cached is determined by the latitude and longitude coordinates of the target reference point position and the preset cache radius, and then the map data is cached to realize the target location information. Search and storage.

However, the traditional map data caching method is generally not intelligent. When the target reference point position changes to the set condition, the target reference point position needs to be re-determined, and the map data is re-algorated according to the target reference point position and the pre-stored buffer radius. Request and cache, for example, the user caches the map data of the target A with a radius of 50 meters. When the user acquires the map data of the target B 60 meters away from A, the new map data is determined according to the coordinates of the target B and the radius of 50 meters. The cache is cached, so that the partial overlap of the A map data and the B map data is repeated, so that the smart terminal needs to re-cache unnecessary map data, and the occupied smart terminal has a large memory, and if it is determined by the new map data, there is a cached When data avoids repeated caching, due to the complexity of the area range description, a lot of calculations are needed to determine the map data that does not need to be repeatedly cached, and a large amount of calculations will cause a huge operational burden on the smart terminal, resulting in a stuck, running The problem is not smooth, affecting the user experience.
