Abstract

The invention discloses a map data processing method, a map data processing device and a storage medium. The map data processing method includes detecting positioning result updated in a three-dimensional space, determining the updated positioning result view field area corresponding to the updated positioning result, acquiring a map fragment corresponding to the updated positioning result and a map fragment corresponding to the view field area, dynamically loading the map fragment corresponding to the updated positioning result and the map fragment corresponding to the view field area in a memory space, and rendering an image, corresponding to the view field area, of the positioning result, in the three-dimensional space on the basis of the loaded map fragments.

Description

technical field [0001] The invention relates to electronic map technology, in particular to a map data processing method, device and storage medium. Background technique [0002] Electronic map is the product of the integration of traditional map and computer technology, Geographic Information System (GIS, Geographic Information System) technology and network technology. The media is a modern information product that comprehensively displays the comprehensive appearance of regions, cities, tourist attractions, etc. as a means of expression, breaking through the limitations of time and space of traditional paper maps, and has richer information content and wider application range. [0003] When using an electronic map, as the positioning position changes, the map data required for rendering will also change. How to quickly obtain the adapted map data and render the output according to the positioning position change, there is currently no effective solution Technical solutio...
