Research And Devising Of Sea-bottom Character Information Analysis System

Seabed-character data is one of the basic elements in ocean environment research, so the study and devising of a sea-bottom character data analysis system is a hot subject all the while. This article is based on the study of basic theories and methods of Seabed-character data analysis system, and on the study of system devising, model design and application methods. And this article mainly deals with the following aspects:(1) analyse and study basic theories in GIS design and system related modeling theories, space inquiry theories and space analysis theories, in order to gain some inspiration and elicitation in space data modeling, space data inquiry modeling and space analysis modeling in sea-bottom character information analysis system devising.(2) Based on software engineering theories, introduce and explore system related methods. Expatiate methods of system function realization by introducing C# programming language and MapX groupware technology; introduce space database technology, so as to provide reference for constructing Seabed-character space database; introduce conventional space data inquiry methods, space analysis methods and space-time analysis methods, so as to provide foundation for approach exploring and improving in sea-bottom character information analysis system function realization.(3) Make an overall structure design and function model design for the system on the basis of the use of seabed character data. And based on the space database theory in GIS, build a space data engine which is grounded on Seabed-character data, and build a space data management model and a Seabed-character space inquiry model; also, design a Seabed-character data space-analysis model on the basis of space analysis theory. Realize the judgment on space trait of sea-bottom samples in different zones with the Seabed-character samples delimitation (horizational, vertical) analysis model; and realize the historical analysis on Seabed-character data and the judgment on its movement trend with the Seabed-character time-space analysis model.(4) By building a sea-bottom character space data engine, and with the Seabed-character space data index technology, realize the function of Seabed-character space data inquiry. And with the Seabed-character sample horizontal and vertical analysis method, realize the function of Seabed-character horizontal static and dynamic delimitation and vertical delamination.This system is a multi-usered and multi-functional special information analysis system, and it offers basic functions of GIS and provides models and methods for Seabed-character space data management and analysis, so as to provide Seabed-character data support for relational fields. With the unceasing apperence of new theories and the development of techniques, the system will be improved step by step.
