Spatial data storage and its application in deep geophysical survey data

Abstract：Deep geophysical survey data are important information on the study of the lithospheric structure. However, data sharing was hindered by the characters of geoscience data such as multi-source, multidisciplinary and massive data. GIS can afford a new approach to data release because of its function of multiple discipline crossing and spatial data processing. The presentation and analytic methods of information in GIS depend on the data model; therefore it is important to construct a data model according with the need on data query and data analysis when the sharing platform was designed using the GIS technique. Several spatial data storage methods and main spatial data models are studied intensively. Finally, a data model is constructed for data release based on Geodatabase according to the characteristics of the deep geophysical survey data.
