Abstract:
With the quick developing of mobile Internet technologies, the clientbased APP is an important way to meet the needs of convenience, high efficiency, movability, and location for meteorological information service. Through research and practice on the fast GISbased visualization technology of meteorological information, which has the features of high update frequency, high spatial resolution, and data quantity, such as radar echoes, gridded weather charts, and MWP outputs, the visualization software SURFER is deployed on the application layer of the server. The preprocessed tiled Raster Map, which was rendered by Google, is deployed on the data layer of the client. The OpenLayers WebGIS is deployed on the application layer of the client. The techniques of data buffering and distributed storage both on server and client application and logic layers are also applied, which ensures the fast visualization for GISbased meteorological information, especially for gridded data, radar echoes, specific pictures, and so on.
