A marine forecast man-machine interaction method based on a GIS synchronization technology

Abstract

The invention relates to a marine forecast man-machine interaction method based on a GIS synchronization technology. The method comprises the following steps: S1, establishing a browser plug-in to download marine meteorological data: establishing the browser plug-in for a browser; Starting a browser plug-in to download the marine meteorological data to an installation directory of a downloaded file; S2, enabling the WebGIS to preload the marine meteorological data by adopting a browser plug-in: when the address accessed by a user is detected to be a marine forecast man-machine interaction system, calling the downloaded marine meteorological data by the browser through the browser plug-in to load; Step S3, establishing a GIS-based multi-user synchronous drawing operation; according to the method, users made of the same marine forecast product are associated, the GIS operation of each user is packaged by using an XML technology, standard specifications of the GIS operation are formed, analysis and warehousing are carried out, and meanwhile, the packaged GIS operation broadcast is sent to browser ends of all participants, so that multi-user drawing synchronization is realized.

Description

technical field [0001] The invention relates to the fields of ocean forecast production, WebGIS, and browser plug-in development, and in particular to a human-computer interaction method for ocean forecast based on GIS synchronization technology. Background technique [0002] Our country is a country with frequent marine disasters, especially the tropical cyclones that affect the coastal areas of our country, which often easily cause large economic losses and even casualties. Ocean forecasting is an important part of marine disaster prevention and mitigation, and can provide technical support for marine disaster prevention and mitigation. At present, the main process of making and reversing my country's marine forecast is: the Marine Environment Forecast Center of the State Oceanic Administration produces nationwide marine forecast products-the provincial forecasting agency / sub-bureau marine environment forecast center uses its own local characteristic forecast production sy...

These data caching strategies will be used in the construction process of the Web system to form a multi-level caching system. However, for huge GIS spatial data, it is not enough to rely solely on server-side caching and client-side caching of a small amount of data. The amount of data that the browser accesses the client has not been fundamentally reduced

[0008] In the prior art, the production of forecasting human-computer interaction products mainly uses the WebGIS platform for drawing operations. Currently, the mainstream WebGIS platforms include ArcIMS from ESRI, MapXtreme from MapInfo, GeoMedia Web Map from Intergraph, SuperMap from Beijing SuperMap, Leaflet etc. can support the drawing operation of WebGIS very well, but a set of comprehensive technology has not been formed inside these WebGIS platforms to realize the synchronous operation of the drawing process on WebGIS, and the synchronous operation of multiple users cannot be reflected. It is a necessary function that needs to be realized in the production process of marine forecast products
