Map data packet full-process adaptive generation and encryption method, device and equipment

The invention provides a map data packet full-process adaptive generation and encryption method, device and equipment. The method comprises the steps of obtaining original data of an electronic map, creating an electronic map service, generating electronic map metadata, generating electronic map tiles in batches, and encrypting the electronic map metadata and the electronic map tiles. Obtaining an illustration rule of the electronic map and resources required by illustration, obtaining a layer through the metadata of the electronic map for rendering, and generating a rendering style file; performing encryption processing on the rendering style file; and creating a hierarchical structure of a map packet based on a preset organization structure, importing the electronic map data into the map packet, and performing compression and encryption processing to generate a map data packet. In this way, distribution of electronic map results in a secret-related intranet environment is realized through the offline map pa
