Abstract

The invention discloses a map dynamic slicing and serialization buffer method, a device, a terminal device and a storage medium. The method is suitable for execution in a computer. The method includes: obtaining a unique URL request generated when a front end loads a map; Analyzing the unique URL request to obtain an address of a map resource corresponding to the unique URL request, and generatinga unique key value according to the address; Querying whether the Kryo caching framework has cached data corresponding to the unique key value according to the unique key value; If yes, reading the data directly from the Kryo caching framework and loading in the current view of the front end; If not, obtaining the corresponding map resources from the map service address and caching into the Kryocaching framework, and then reading from the Kryo caching framework and loading into the front end. The embodiment of the invention is implemented, a fast and high-quality drawing effect can be achieved under the condition of a large amount of data.

Description

technical field [0001] The present invention relates to the technical field of map caching, in particular to a method, device and storage medium for dynamic slicing and serialization caching of maps. Background technique [0002] A map cache is a directory containing map tiles for the entire map extent at different scales. That is, a cached map service is a service that can use static images to quickly provide maps. [0003] In the prior art, the map is directly cached through the ArcGIS Server. ArcGIS Server is an enterprise-level GIS software platform released by ESRI that provides Web-oriented spatial data services. It provides a framework for creating and configuring GIS applications and services, which can meet the various needs of different customers. Since version 9.2, ArcGIS Server has included the AreSDE spatial data engine, which is used to manage geospatial databases based on multi-user and multi-transaction through a variety of relational databases.
