Design And Implementation Of Visualization Platform For Marine Hydrological Data

In the study of marine environment,the visualization of marine data is an important part of it,which is of great significance to assist in the analysis of marine elements,the display of environmental changes,and the exchange and transmission of marine information.With the improvement of marine exploration equipment technology and the gradual accumulation of marine exploration data,it is difficult for the data analysis process to complete large-scale marine data analysis.Building a marine data visualization platform with data visualization as the core,for reducing the basic process of marine environmental research,Improving the efficiency of data processing is of positive significance,and it is an important software tool for realizing marine data storage management,calculation analysis and expression of results.This article starts with the study of ocean data visualization.Taking marine hydrological element data as an example,the key technologies of data storage structure and data visualization methods are studied.Based on the comparative analysis of existing technologies or methods,a set of suitable for this platform is proposed.The hydrological data storage and visualization method,including marine hydrological scalar data visualization method,vector data visualization method,and vector data dynamic description visualization method.Through field investigations,understand the problems in the processing of marine environmental data,formulate the expected goals of the visualization platform,design the specific functions and development processes of the Web platform,and establish the B/S structure as the software service framework.Finally,the open source SSM project framework was used to develop the marine hydrological data visualization platform,which realized the marine data visualization platform integrating multi-user collaboration,data storage and management,data statistical calculation,results visualization,information release,safety management and monitoring.Specifically,the main work of this article are:1)The characteristics of marine scientific data transmission and storage format are analyzed.This article mainly takes NetCDF as an example to analyze the storage format of hydrological element data in detail,and on this basis,proposes and designs a multi-dimensional element data fusion storage technology to achieve Multi-scale data fusion.2)Organized the basic principles of visualization of hydrological element data,including the basic methods of visualization of scalar data and vector data in the marine environment research process,and on this basis,proposed and designed the dynamic visualization technology of vector data to achieve the vector data Dynamic expression.3)Through the investigation of the relevant marine environment research work,the software functions and performance are designed in detail,and the platform service framework and function module implementation method are proposed according to the specific needs.4)Using Web software development technology to realize the specific functions of the marine hydrological data visualization platform,and verifying the feasibility of multi-dimensional element data fusion storage technology and vector data dynamic visualization technology.
