The Raster Image Splicing of Using Oracle Spatial Technology to Research the GeoRaster Data

Abstract

GeoRaster is a feature of Oracle Spatial that let you store, index, query, analyze, and deliver GeoRaster data, that is, raster image and gridded data and its associated metadata. Using geographic information system GeoServer, we can release the raster map data, and allow users to update, delete, insert the characteristic data. Then, it can be easier to share the space geographic information by GeoServer between users. In fact, due to the enormous data size of the remote sensing image information, so that the same region of image information can be divided into many grids data blocks, and stored into sheets of raster images. To facilitate GeoServer to publish map data, based on the Oracle Spatial GeoRaster architecture, which provided by Oracle database, as well as the “SampleCode_For_Loader” project sample provided by the website, georaster_tools.jar toolkit, we do the secondary development. We splice the region of the same grid data block raster images, and import them into the Oracle database, then make the data as a whole.
