Welcome to rasdaman,

the Scalable Multi-Dimensional Array Analytics Server!

This is the website of the open-source rasdaman ("raster data manager") project. Rasdaman extends standard relational database systems with the ability to store and retrieve multi-dimensional raster data (arrays) of unlimited size through an SQL-style query language. On such sensor, image, or statistics data appearing, e.g., in earth, space, and life science applications rasdaman allows to quickly set up array-intensive services which are distinguished? by their flexibility, speed, and scalability.

Rasdaman is brought to you by the guys writing the geo raster standards, including OGC WCS and WCPS, the OGC raster query language. The Petascope component of rasdaman provides service interfaces based on the OGC WCS, WCPS, WCS-T, and WPS. For several of these, rasdaman will be reference implementation. Since April 2011, rasdaman is available on the OSGeo Live DVD.

Rasdaman embeds itself smoothly into PostgreSQL; further, a GDAL rasdaman driver is available, and likewise a MapServer integration (beta). A PostGIS query language integration is under work, see our planning.

EarthLook is a demonstration site showcasing rasdaman in a variety of 1-D to 4-D geo use cases.
