Design Area Geophysical Data Model Based On Geodatabase

Along with the development of information technical, every professionaccelerates the digital construction, and area geophysics is the sametoo. The support of national ocean subject and China Geological Survey'sproject push forward the informational process of area geophysics. Thefirst place of digital is the construction of industry class data model.This thesis ,which is based on analyzing of mass and multi_source areageophysical data, combined with the main method of spatial data model–geodatabase, brings forward constructed flexible and efficiently areageophysical data model's basic thought and structure and uses UML and CASETools constructing area geophysical data model. To proof the model'sflexibility, apply the model in area geophysical data management systemand test its efficiency.Moreover this thesis summarize the main step of construction ofindustry class spatial data model based on geodatabase.(1)Analyze thedata characteristics.(2)Concept design is to analyze data specialsubject and fix the space conference.(3)Logic design is to assignentities of each special subject and each entity's mode of expression,fields and the relation.(4)Physics design is to deploy the concept andlogic entity, which contains UML model design, spatial domain definition. In summary, this thesis,on the one hand constructs the industry classarea geophysics data model,on the other hand explores the design methodof spatial data model's design based on the geodatabase.
