Human-computer interaction method for ocean forecasting based on gis synchronization technology

Abstract

The invention relates to a human-computer interaction method for ocean forecasting based on GIS synchronization technology. Step S1, set up a browser plug-in to download marine meteorological data: set up a browser plug-in for the browser; then, start the browser plug-in to download the marine meteorological data to the installation directory of the downloaded file; Step S2, use the browser plug-in to make WebGIS preload the ocean Meteorological data: When it is checked that the address accessed by the user is the ocean forecast human-computer interaction system, the browser calls the downloaded ocean meteorological data through the browser plug-in to load; step S3, establishes a GIS-based multi-user synchronous drawing operation, and Users of the same marine forecast product are associated, and the GIS operation of each user is encapsulated using XML-based technology to form a standard specification of GIS operation and parsed into the database, and at the same time, the encapsulated GIS operation broadcast is sent to the browsers of all participants terminal to achieve multi-user drawing synchronization.

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
