Welcome to rasdaman -- the World's Leading Array Database

 Array Databases allow storing and querying massive multi-dimensional  arrays, such as sensor, image, simulation, and statistics data appearing in domains like earth, space, and life science.

The rasdaman ("raster data manager") is the leading array analytics engine distinguished by its flexibility, performance, and scalability. Rasdaman embeds itself smoothly into  PostgreSQL, but can also run standalone on file systems. In fact, rasdaman has pioneered Array Databases being the first fully implemented, operationally used system with an array query language and optimized processing engine.

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.


  • November 2014 -- the  rasdaman QGIS plugin has been approved and can easily be installed straight from QGIS...yet another powerful platform supported by rasdaman, in addition to GDAL, MapServer, and ERDAS Imagine.
  • November 2014 -- in the final review of EU project  EarthServer (which has substantially supported rasdaman community development!) reviewers were impressed by all the achievements; among others, at the premises of the European Space Agency (ESA) a 170 Terabyte rasdaman space/time database was built.
  • October 2014 --  ohloh reports that the rasdaman codebase now is worth more than 7 million US$. wow.

  • March 2014 -- version 9.0.1 has been released improving some issues observed during large-scale migration (release notes).
  • February 23, 2014 -- rasdaman 9.0 has been officially released, see full release notes.
  • January 2014 -- several more specifications crafted by the rasdaman team get adopted as official standards: WCS Scaling Extension, WCS Interpolation Extension, WCS Earth Observation Application Profile.
  • December 16, 2013 -- the WCS Range Subsetting Extension, crafted by the rasdaman team, gets adopted as official OGC standard.
  • December 06, 2013 -- rasdaman is OGC's official Reference Implementation for WCS Core:

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.
