    77This is the website of the open-source rasdaman ("''__ras__ter __da__ta __man__ager''") project. Rasdaman extends standard relational database systems with the ability to store and retrieve multi-dimensional raster data (''[http://en.wikipedia.org/wiki/Array arrays]'') of unlimited size through an [http://en.wikipedia.org/wiki/Sql SQL]-style query language.
    88
    9 The information category "array" appears - as '''sensor, image, or statistics data''' - in manifold [wiki:ApplicationDomains applications], such as '''earth sciences, space sciences, life sciences, engineering, and multimedia'''. Rasdaman allows to quickly set up array-intensive [wiki:Features services] which are [wiki:WhyRasdaman distinguished] by their flexibility, speed, and scalability.
    10 
    11 The petascope plug-in to rasdaman, which is part of the distribution, offers '''[http://www.opengeospatial.org OGC] standards based services''' on multi-dimensional '''geo raster data'''.
    12 Petascope implements the OGC Web Coverage Service (WCS) standards for gridded [http://www.opengeospatial.org/ogc/glossary/c coverages], i.e., raster data: [http://www.opengeospatial.org/standards/wcs Web Coverage Service] (WCS) for '''simple data subsetting'''. rasdaman will be the WCS 2.0 reference implementation; [http://www.opengeospatial.org/standards/wcps Web Coverage Processing Service] (WCPS) which defines a '''language for the extraction, processing, and analysis of raster data''' (see also this [http://www.ogcnetwork.net/wcps WCPS info page]); petascope is the WCPS reference implementation; [http://www.opengeospatial.org/standards/wcps WCS Transaction Extension] (WCS-T) for '''updating raster data''' offered by a WCS-conformant service.
     9On such '''sensor, image, or statistics data''' appearing, e.g., in '''earth, space, and life science''' [wiki:ApplicationDomains applications] rasdaman allows to quickly set up array-intensive [wiki:Features services] which are [wiki:WhyRasdaman distinguished] by their flexibility, speed, and scalability. The petascope component of rasdaman provides service interfaces based on the [http://www.opengeospatial.org OGC] [http://www.opengeospatial.org/standards/wcs WCS], [http://www.opengeospatial.org/standards/wcps WCPS], [http://www.opengeospatial.org/standards/wcps WCS-T], and [http://www.opengeospatial.org/standards/wps/ WPS]. For several of these, rasdaman will be reference implementation.

    1411Rasdaman embeds itself smoothly into [http://www.postgresql.org/ PostgreSQL]; a [http://www.gdal.org/ GDAL] rasdaman driver is available, and likewise a [http://mapserver.org/ MapServer] integration (beta). A [http://postgis.refractions.net/ PostGIS] query language integration is under work, see [wiki:Planning our planning].
