Abstract

The invention relates to the technical field of meteorological data processing, and discloses a method for displaying meteorological data in webgis, which comprises a data processing module, a data message service module, a rendering service module, a slice message service module, a tile segmentation service module and a storage module. The data processing module is used for generating a grey-scale map from the client data source and storing the grey-scale map in the storage module; the data message service module is used for controlling the rendering service module to render the grey-scale map; the rendering service module is used for rendering the grey-scale map in the storage module into a PNG picture and storing the PNG picture in the storage module again; the slice message service module is used for sending the received slice message to the tile segmentation service module; and the tile segmentation service module is used for segmenting the PNG pictures in the storage module. According to the method for displaying the meteorological data in the webgis, the tile segmentation service module generates a plurality of tiles with the size of 256 * 256, and the problem that a single large picture is loaded slowly is solved.

Description

technical field [0001] The invention relates to the technical field of meteorological data processing, in particular to a method for displaying meteorological data in webgis. Background technique [0002] Most of the current solutions use the rendering engine embedded in the browser to render data. There are requirements for browser compatibility and client performance, and the current rendering engine embedded in the browser is not as powerful as the professional rendering engine. The rendering engine embedded in the browser is mostly driven by code and lacks friendly design functions. [0003] The first solution is to use the rendering engine embedded in the browser for rendering, and to break through the limitations of design capabilities through powerful coding capabilities. This method has high requirements on the skill level of developers and a long development cycle. But the final effect cannot be compared with professional rendering engine effect. [0004] The se...
