Mass map data dynamic loading method

The invention discloses a mass map data dynamic loading method, and relates to the technical field of map dynamic loading, by collecting user habit data, setting element classes for different retrieval range levels in an LOD manager based on the user habit data, and pre-storing prediction element objects in a system cache, and when a map scheduling instruction is received, the user habit data is sent to the LOD manager; obtaining an element class corresponding to a retrieval range level as a to-be-displayed element class, retrieving a to-be-displayed mapsheet from all mapsheets of the map project based on a to-be-retrieved range, and retrieving an element index set from all element object indexes, all to-be-displayed element objects in the element index set are complemented into a system memory from a system cache and a system hard disk in sequence, and the to-be-displayed mapsheet and all the to-be-displayed element objects are rendered; the response speed of the system is improved, and the experience feelin
