4 GeoRaster Data Query and Manipulation

This chapter describes how to perform several important GeoRaster data query and manipulation operations. Typical GeoRaster data query and manipulation involve most or all of the operations described.

See also the operations in GeoRaster Database Creation and Management.

Other chapters in this book cover advanced topics (Raster Algebra and Analytics and Image Processing and Virtual Mosaic), and provide detailed reference information about GeoRaster PL/SQL packages ( SDO_GEOR Package Reference, SDO_GEOR_ADMIN Package Reference, SDO_GEOR_AGGR Package Reference, SDO_GEOR_RA Package Reference, and SDO_GEOR_UTL Package Reference).
