DOM database based on ArcSDE
To solve the problems of massive,multi-source provincial image data management,storage,retrieval,and so on,ArcSDE spatial data engine architecture and data model are used to establish a provincial DOM database by combining Oracle 10g database management system.The establishment of the database of remote sensing images successfully solve some specific problems of the block image data processing,image pyramid building,data compression,etc.Meanwhile,the grid index structure and the method of retrieval based on contents are adopted.It has been proved by practice that the disposal of the images by level and block can store the images in a fast and efficient way.The combination of grid index accelerates the retrieval of the images,and the DOM data can be effectively organized,security storage and effectively used.
