Research Of Actual Population Data Mining & Visualization Analysis Based On GIS

With the development of our economy and society, the number of actual population who don't have a regular shanghai residential identification like non-shanghainess and foreigners is rapidly increasing under the stimulus of the new market-economy, which has brought huge pressure and different challenges to population management, city's correspondent service and the task of the city's safety and security. It makes the data and relationship between actual population more complex and unpredictable.Therefore, on the basis of data mining and relationship discovery, it has become an urgent task for the government and correspondent departments to intensify the management and make full use of the actual population information.In order to deal with the pressing social practical needs and promote the analysis on current demographic data and the research of visualization.Facing to data mining on actual population and visualization pattern of its result, this essay has conducted the research based on the practical application of shanghai actual population management system.Firstly, make an analysis on the characteristics of enormous actual population data and create the data modeling.Secondly, conduct a discussion on the criteria of actual population relationship discovery and create the correspondent evaluation norms.Thirdly, try to design a visualization model that could be able to demonstrate the procedure and result of the discovery based on population relationship.Finally, with the help of the GIS software platform,I have completed the system of data mining and visualization based on actual population.Guided by the outlines above, this paper has completed the work as follow:(1)This system has summarized and analyzed the characteristics of mass actual population data. Having designed a data model of five elements of actual population, based on which 1 have probed into abstract criteria of actual population relationship discovery. Still further the correspondent evaluation norms have been created in accordance with the criteria.(2) Referring to actual population data framework, I have designed a five-element actual population database table structure based on actual population data and relationship modeling. (3)Two visualization models which named as relationship chain and cubes have been brought up based on actual population data mining of GIS through a serious research, analysis, contrast and practice.Then I have worked out a feasible designing program and procedures according to their own respective information and pattern characteristics.(4) With the help of GeoServer map service, adopting "Struts+Spring+ Hibernate" frames and storage process technology, I have designed a visualization system of actual population data mining based on GIS under the J2EE environment. Besides, I have brought the actual population relationship discovery and its visualization function into implementation through computer programming.
