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.

OSGeo Incubation logo 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 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.

Download, Installation, Documentation

Go to the Download page for instructions. The installation steps are described on the Install page. There is ample documentation, including query and programming examples (check out our tutorial on spatio-temporal data with rasdaman too).


The  Large-Scale Scientific Information Services research group at  Jacobs University Bremen is the core development team. Feel free to contact us!

A dedicated research spin-off company,  rasdaman GmbH, provides software enhancements, expert consultancy, participation in projects, and joint ventures on a commercial basis to foster widespread use of rasdaman.
