Map rendering method and device, equipment and storage medium

Abstract

The invention discloses a map rendering method and device, equipment and a storage medium, and the method comprises the steps: responding to a received map construction request, and determining a to-be-rendered data source; creating a to-be-rendered layer for each to-be-rendered data source, and creating a map view window; loading all the layers to be rendered to a map view window; and when the map rendering instruction is received, rendering the to-be-rendered layer in the map view window, and generating the map view, so that the used rendering resources are more effectively reduced, and the rendering efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image rendering, in particular to a map rendering method, device, equipment and storage medium. Background technique [0002] In GIS, surveying and mapping and other related fields, in addition to loading various online maps, it is also necessary to load various raster data and vector data, such as shp data, tif data, etc. In addition, there are a lot of data that can be abstracted into layers for management, such as ship type during water survey, aircraft for aerial survey, compass, scale, etc. Then how to quickly manage and efficiently render these online maps and data will become a problem that must be solved in the development of such application software. [0003] In the prior art, image rendering is usually performed layer by layer directly every time the map data changes, so as to obtain the target map data. However, the above method needs to re-render each layer every time the data is up...
