|Oracle® Spatial GeoRaster
10g Release 1 (10.1)
Part Number B10827-01
Oracle Spatial GeoRaster provides usage and reference information for the GeoRaster feature of Oracle Spatial, referred to in this guide as GeoRaster. GeoRaster lets you store, index, query, analyze, and deliver GeoRaster data, that is, raster image and gridded data and its associated metadata. GeoRaster provides Oracle Spatial data types and an object-relational schema. You can use these data types and schema objects to store multidimensional grid layers and digital images that can be referenced to positions on the Earth's surface or a local coordinate system.
GeoRaster is not a separate product. It is available when you install Oracle Spatial.
Note:To use GeoRaster, you must understand the main concepts, data types, techniques, operators, procedures, and functions of Oracle Spatial, which are documented in Oracle Spatial User's Guide and Reference.
This preface contains these topics:
This guide is intended for anyone who needs to store GeoRaster data in an Oracle database.
You should be familiar with Oracle Spatial, PL/SQL programming, and Oracle object-relational technology.
You should also be familiar with raster concepts and terminology, techniques for capturing or creating raster data, and techniques for processing raster data. For example, this guide mentions that data can be georeferenced if it is georectified; however, it does not explain the process of georectification or the challenges and techniques involved.
Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
