Abstract

The invention provides a data rendering method, device and equipment and a storage medium, and relates to the technical field of geographic information systems. The method comprises the following steps: firstly, reading raster data of a plurality of layers from a hard disk, wherein the raster data of each layer stored in the hard disk is data obtained by rasterizing vector data of each layer; merging the raster data of the same index number of the plurality of layers to obtain merged raster data, the index number of each raster data being used for indicating the position of each raster data relative to a preset reference point; and finally, rendering according to the merged raster data. By applying the embodiment of the invention, the rendering time can be saved, and the data rendering efficiency is further improved.

Description

technical field [0001] The present application relates to the technical field of geographic information system (Geographic Information System, GIS), in particular, to a data rendering method, device, device and storage medium. Background technique [0002] GIS (Geographic Information System, GIS), also sometimes called geoscience information system, is a very important spatial information system. Vector data is a kind of basic information stored and managed in GIS, including entities composed of points, lines, and surfaces, including road networks, buildings, vegetation, and landforms. In order to visualize vector data, it is necessary to visualize the vector data. [0003] Currently, vector data is visualized directly by rendering in the viewport using vector data. However, due to disadvantages such as complex structure of vector data and large amount of data, it takes a long time to render vector data, which leads to a decrease in rendering efficiency of vector data. C...
