Geoscientifical Database Model Of Hunan Land & Resoures And Applicational Research Of Data Fusion Technology

SV is the time for geoscientifical research development. The development of the means of geting geoscientifical spatial information, computer high speed evolution and satellite blastoff made RS and GIS technology be more advanced and it is possible to deal with stupendous data of our planet, environment and cultural phenomena. it is a starved projection to be solved that how to use stupendous data and not submerge by them.The concepts of data~fusion came into being in 70. It is a crossntegrated subject include the theory, technology and method dealing with multiinformation in the field of military. Its produce , formation and development is the result of modern science technology, especially the rapid development of highew technology. The development of datausion made it be the integration and application of many subjects, and cane into being a new field of foreword technology from the integration of many traditional subjects and new field. It is a new research field of geoscience. The application of data-fusion technology provided a new method for the management and analyse of geoscientifical data. It makes some changes in the traditional process of estimation anddecisionaking, and provided new tools and idea for the work of estimationThe important research includes the design of geoscientifical spatial databaseodel, the research of datausion technology, the development of geoscientifical spatial database information system and the application of information system in ore prediction.We select Arc/Info as the development system of geoscientifical information system from the all kinds developmental model of GIS for geoscientifical data characteristic, build thegeoscientifical information system in the developmental environment of rc/Info. It is aperfectable geoscientifical information system, and can be replaced by other GIS system, and provides complex analyses feature of all kinds, it provides an important method for estimation of geoscientifical workParticular research content be listed as follows:In the first chapter, it discussed the research development of geoscientifical information and datausion technology, summarized data resources, research background, purpose and significance of geoscientifical spatial database information system, arranged the main research work.In the second chapter, the natural geographical situation, main distribution of ore resources, background of geostructure and regional geology and background of regional geochemistry are studied. It provided a solid basic for the analyses of information system and the design of geoscientificaL spatial databaseIn the third chapter, the design of the model of geoscientifical spatial database. comprehended the feature and main type of geoscientifical data and then designed the structure of geoscientifical spatial database are dealt with. The structure of geoscientifical spatial database was made up of attribute and spatial data. We managed attribute by large database of SQL server, and managed spatial data by the interior-database of the info database of Arc/Info. The separation of spatial and attribute data made the struture of data be more reasonable.In the fourth chaPter, the author studied the national and international research situationof data--fusion technology, discussed the .ode1, hasic princiDle, technology research, i.ple.enttechnologv of data--fusion, fa.i liar .ethod and data--fusion of GIS and 6IS and 8S.The .ain rePresehtion of Data--fusion of geoscientifical data being rePresented hy Model fusionand infor,ation fusion.
