摘要：Geoimagery and raster gridded data are growing exponentially. As a result, we face many challenges. This paper discusses two of the major challenges. One is how to effectively and efficiently archive, manage, process and deliver all those geoimage data. Another challenge is how to make the geoimages and professionally extracted information available to broader audiences so that enterprises and mass consumers can benefit more from our work. This paper focuses on the database server technology, which is one of the key areas that is essential and foundational for solving the above two challenges and beyond. It proposes a new enterprise database- centric approach for geospatial image and raster data management and processing. The key concept of this approach is to enhance and leverage enterprise IT technologies and provide a database-centric solution for image data management as well as key image processing operations. It consists of three major components: a new native database data type for raster data, a server-side image processing and raster operation engine and a standard-based user-friendly interface. It's designed to work in a client-server environment as well as in any multi-tier architecture. The advantages and benefits of this approach are discussed. The Oracle Spatial GeoRaster was designed based on this approach. A series of tests and research using the Oracle GeoRaster technology were conducted and are partially presented in this paper. The results show that this approach is practical, easy-to-use and truly scalable and performant. This database-centric approach is a viable solution for geospatial image management and processing
