The Design And Implementation Of Digital Airborne Geophysical Data Management System

From the beginning of the50’s of the twentieth Century，aero geophysical surveytechnology began to appear, Airborne geophysical institute has accumulated variousairborne geophysical data, research a lot. But how to better manage, use these data,may be we want to face future problems. The paper’s main objective is to study theAero Geophysical Data Management system. The paper’s main objective is to studythe Aero Geophysical Data Management system.Digital airborne geophysical data management system is mainly composed ofairborne geophysical data acquisition subsystem and aero geophysical databasemanagement system. Two subsystems are Microsoft framework based on.NET,through the management and operation of data in Oracle database. Acquisition system,literally can see is the external data collection to the database. Airborne geophysicaldata mainly through import and entry into the acquisition, import is the main method,is the data file to the database. The aero geophysical database management system ismainly carried out a series of processing on the database or the local data according todifferent user needs.Data acquisition system data obtained will finally saved to the aero geophysicaldatabase, must go through import, data entry, storage before the examination, afterstorage, query data inspection work. Data import, entry is the use of manual input datato the database. System to check on the data in storage before, only to meet theconditions of the data can be input. After storage, mainly includes the system check,check topology check, manual inspection, manual verification more inspection, theinspection and contains a variety of inspection, and check the type is also different,thus greatly ensure no redundant data. Query data using the basic query, query log andthe log query three query methods are in accordance with the needs of users.Database management system is used for data processing, query, statistics andextraction. The user can handle remote data in the database, it can handle the localdata, but also the local data and remote data in the database were analyzed. At thesame time, a database management subsystem can prepare to save in the database forthe data acquisition subsystem. The aero geophysical database management systeminclude: user login, system management, data management, data query and the systemhelp five parts. The System management module was formed by3Sub moduleswhich are modify user login, user information management and exit managementsystem.The function of the data management module are transforming the format of data、importing the data of measuring points、deleting measuring points and managingthe information of measurement zone. Data query module project by the query andquery sub module two.
