The Construction Of Data Collection System For Aero Geophysical Prospecting Database

The Construction of Collection System for aero geophysical prospecting data camefrom the project of "the aero geophysical prospecting and remote sensing database"schemed by geological survey department of China, the project aimed to construct anaero geophysical prospecting database of China and its managing system ofinformation, the data collection system of aero geophysical prospecting database wasits subproject.Since the geological survey department began to fly for exploration, theyaccumulated lots of aero survey data and researching production, for the sake of usingthe data expediently, they required to build a systemic, high-powered and kindlysystem of database. The collection system of aero geophysical prospecting data usedthe microsoft's .net developed environment, and managed the database by oracle, anddisplayed the spatial data by ArcGis,achieved the storage of data, checking andresearching.In this thesis, it mainly introduced as follow:There was a huge amount of aero geophysical survey data, because of thisproblem we used the blob-technic which place this file and picture to a blob-field instorage, and the instructed data to a usual-field, so saved the data room efficiency.According to relativity of the aero geophysical survey data and geography information,we displayed survey data by figure of arcgis and grid, and switch smoothly betweenthem.In order to ensure the correctly and uniquely, the collection system of aerogeophysical prospecting data constructed a collect-database and a formal-database.Before and after the data deposited in the collect-database, we took a series of checkas follows: check before saving, system check, check artificially and re-checkartificially, and gave a exactly check log for modifying the data. The data whichpassed the checks allowed to place into the formal-database.For the data researching, the system can created research-windows dynamically,the users can looked up the data by one or several items, it made the users to get thedata conveniently and swiftly.The collection system of aero geophysical prospecting database used thestructure of client-to-server for the collection and using, and it was easy to manageand upgrade. On the aspect of security, the user logged on the client and verify theidentify on the server by network, then fix on the role of the system with distinctrights by user's code, it matched the user's demands better.
