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. During a review in Fall 2014, independent experts unanimously have attested that, based on "proven evidence", rasdaman will "significantly transform the way scientists access and use data in a way that hitherto was not possible".

Big Data Challenge winner in the international Copernicus Masters competition rasdaman ("raster data manager") is the leading array analytics engine distinguished? by its flexibility, performance, and scalability. Rasdaman embeds itself smoothly into relational databases, but can also run standalone on the file system. In fact, rasdaman has pioneered Array Databases being the first fully implemented, operationally used system with an array query language and optimized processing engine with unprecedented scalability. Known rasdaman databases exceed 230 TB; with EarthServer, intercontinental fusion of Petabyte datacubes is being established. In 2014, rasdaman was selected the winner of Big Data Challenge in the international Copernicus Masters competition.

OGC listing of rasdaman as WCS Core Reference Implementation Starting with version 9.0, rasdaman is official OGC WCS Core Reference Implementation, and candidate reference implementation for all WCS extensions. Further, rasdaman is listed in the GEOSS Component and Service Registry.

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). Drivers are available for integration with GDAL, MapServer, R, and several more.

For the business value of rasdaman, see the listing on OpenHub. is a demonstration site showcasing rasdaman-enabled OGC WCS and WCPS in a variety of 1-D to 4-D geo use cases.


  • October 2015 -- OGC adopted our WCS-T specification as a standard, which will tremendously ease coverage maintenance and coverage service mashups
  • October 2015 -- In Tokyo, the ISO SQL Working Group resolves that the SQL/MDA ("Multi-Dimensional Array") specification is to be rolled out for CD ballot; this specification is based on rasdaman and written by us
  • July 2015 -- following earlier prerelease, the stable version of rasdaman 9.1 is released now, with tons of improvements and new functionality
  • June 2015 -- OpenHub attests rasdaman a "large team, in the top 10% of all project teams on Open Hub"
  • February 2015 -- Currently we are aware of 230 TB of rasdaman databases of atmosphere, ocean, land, and planetary science data. Let us know if you have another Big Data instance running!
