Study on sharing mechanism and applications of raster data based on Oracle 10g

The sharing mechanism of spatial raster data offers a support to data exchanging.The sharing program provides a platform for interchanging datum and improves the utilization of remote sensing datum.In the sharing program,the function of the new component of GeoRaster of the Oracle 10g is adopted.At the same time,the component of Commons-FileUpload is developed to upload files and the component of FileInputStream and FileOutputStream to read and write files separately.Thus data sharing is realized on Web,and the system can produce multitudinous types of resolution by pyramidal structure according to user's requirements.So the application reveals that this sharing mechanism fits the request of the large raster files shared.
