Abstract

The invention provides a mass vector data display method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining original vector data under a latitude and longitude coordinate system, and converting the original vector data into target vector data under a plane coordinate system; obtaining a map tile, and cutting the target vector data based on the map tile to obtain a plurality of vector sub-data blocks corresponding to the map tile; and displaying the map tile and the plurality of vector sub-data blocks corresponding to the map tile according to a current window. According to the method, the target vector data is cut based on the map tiles, so that the massive vector data can be displayed on the premise of ensuring the interaction and operation speed.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method, device, electronic device and storage medium for displaying massive vector data. Background technique [0002] With the continuous advancement of informatization construction, data visualization applications based on electronic maps are becoming more and more common, but if the amount of data is too large, especially in the browser environment, there will be lags, delays, and crashes. [0003] In order to solve the situation that the vector data is stuck, delayed and collapsed in the process of visualization, in the prior art, the patent application number CN201310364855.8 discloses a method and system for superimposing a base map on a thematic map, which combines vector data with Display in the form of special pictures. [0004] Although the existing technology solves the problems of slow running speed during the display of massive vector data, resulting in st...
