Research On Archaeological Information Platform And Key Technologies Based On WebGIS

With the advancement of science and technology,the number and types of archaeological data are increasing,and traditional information management technologies have been unable to effectively manage their spatial and attribute data.By analyzing the requirements of archaeological information system,this paper applying geographic information technology and Internet technology to the management of archaeological information,and combines with J2EE large enterprise development platform,useing SSH framework,GeoServer,PostgreSQL and other related technologies to develops an archaeological information platform based on WebGIS,realizing the management and sharing of archaeological information,and studing the key technologies of three-dimensional visualization,optimizing the traditional spatial interpolation algorithm,and establishing a three-dimensional stratum model.The main contents and achievements of this paper are as follows:(1)By applying J2EE architecture and SSH framework technology,this paper constructs the system framework of data layer,service layer and application layer.According to the actual situation of archaeological work,the requirement of system is analyzed,and the functional modules were designed;On the database,PostgreSQL spatial database is selected,the attribute database and spatial database are designed.(2)Three-dimensional visualization of strata in archaeological sites is studied,and basic models and interpolation algorithms in geological m odeling are discussed.By increasing the weight k of the control directivity,the problem of poorly considering the inverse distance weight interpolation method in spatial heterogeneity is optimized.Realize the three-dimensional visualization of archaeological strata,so that the stratum that under the archaeological site can be more directly and vividly displayed.(3)According to the specific needs of the Qin Shihuang Mausoleum Museum,combined with the construction of WebGIS-based system and the research on key technologies in spatial information processing,the archaeological information management and display platform of Emperor Qin Shihuang's Mausoleum was established to realize the application of geospatial information,the management of archaeological basic information and the display of three-dimensional stratigraphic information.It solves the problems of information management and display in modern archaeological work,improves work efficiency,optimizes the display of three-dimensional information,and realizes the systematicization of archaeological information management,It is of great significance to carry out archaeological work in science and to improve the level of archaeological research.
