The Research And Realization Of Urban Image Data Management System Based On ArcEngine

Because of the core of the geospatial data in China are mainly from the vector map database into digital orthoimage spatial data framework,the image of geometric progression growth data in the application of GIS system is becoming more and more widely.These scattered image data is very hard to manage, and also bring some trouble to work. According to job requirements of the relevant departments in Fuxin, I set up the city image data management system, making up for the deficiencies of traditional management and improving the use value of image dataThis paper mainly done the following work:1.On the basis of analyzing the existing image data management technology,using the mixed file database storage, basing on the C# ArcEngine technology combined with Oracle database method to establish the C/S architecture of the city image data management system.The system make full use of the advantage of GIS professional model, integrating them into the system to ensure the diversification of the function of city image data management systems.The whole system operation is very easy.The user's interface is pleasing to eyes. The system require low computer configuration, having strong practicability and portability.2. High-efficiency query to locate. The urban image data management system is to query the image data quickly and accurate positioning of the target.The system adopt the method of flexible customization directory tree to manage data.It solves many organization problems of image data,such as different special, time,scale resolution and so on. The system is mainly based on the metadata query to unified manage image data, in addition to providing a keyword query, click query,pull boxes query, integrated query and so on to achieve a rapid on image data positioning also.3. It implements diverse visual ways.The image data management system has two special functions which different from other features are rolling tool and linkage display.When two layers are stacked, using the rolling tool can observe the shutter in the space of two superposed layers by controlling the transparency of the upper case of the image; The linkage display change the display in a window, the other linkage window will change as also.Keeping two windows display the spatial extent consistent achieve better comparative analysis between images.4. Through providing convenient tools on previous collection of image data for coordination and consistency,the system makes these functions come true,including image pre-processing,image storage,image distribution and so on.
