Welcome to rasdaman — the World's Leading Array Database

This is the website of the rasdaman ("raster data manager") open-source project. Rasdaman is a domain-neutral ​Array Database System: it 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. In fact, rasdaman has pioneered Array Databases being the first fully implemented, operationally used system with an array query language and optimized processing engine.

On such sensor, image, simulation, and 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 embeds itself smoothly into ​PostgreSQL.

Next-Generation Geo Raster Server. Rasdaman is brought to you by the guys writing the geo raster standards, including ​OGC WCS and ​WCPS, the OGC raster query language. The [PetascopeUserGuide 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 (a short get started guide). A ​GDAL rasdaman driver is available, and likewise a ​MapServer integration (beta). A ​PostGIS query language integration is under work, see our planning. In comparison to PostGIS Raster, rasdaman scales and supports n-D instead of 2-D and automatizes tile management.

For the business value of rasdaman, see the ​listing on ohloh. ​EarthLook is a demonstration site showcasing rasdaman in a variety of 1-D to 4-D geo use cases.
