AI Technical Summary

Problems solved by technology

When the scene is switched, the problem is particularly serious when drawing a finer scene in a local area. Either the drawing of the grid is not fine enough to meet the needs, or the subdivision is sufficiently fine, but the amount of data drawn is too large. Large, the rendering efficiency cannot keep up, and cannot meet the needs of use

Abstract

The embodiment of the invention provides a Beidou grid drawing method and device based on WebGL, equipment and a computer readable storage medium. The method comprises the steps of obtaining data of a Beidou grid needing to be drawn based on an asynchronous thread calling mechanism; and rendering and updating the Beidou grid which needs to be drawn currently according to the data. In this way, efficient self-adaptive calculation of the Beidou grid of the area needing to be drawn can be achieved, and the drawing efficiency is improved.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of geographic information systems, and more specifically, relate to a method and device for drawing Beidou grids based on WebGL. Background technique [0002] With the development of geospatial informatics, the acquisition and update of geospatial information has made great strides from traditional 2D and 2.5D to true 3D. The field expands into the broader field of Earth system science. In addition, the continuous maturity and development of data acquisition methods have made the prototype of spatial big data gradually appear, and have attracted great attention from the industry, science and technology circles, and government departments. Spatial big data puts forward higher requirements on traditional data organization methods due to its massive data capacity and multi-source, multi-scale, multi-morphology, and multi-temporal characteristics. [0003] Earth sphere meshing,...
