Welcome to rasdaman!

This is the website of the rasdaman project. Rasdaman ("raster data manager") is an array database system (also called "raster database system"). It allows to retrieve and maintain multi-dimensional ​arrays of unlimited size stored in standard relational databases through an ​SQL-style query language. The information category "array" appears - as sensor, image, or statistics data - in manifold applications, such as earth sciences, space sciences, life sciences, engineering, and multimedia.

Rasdaman allows to quickly set up array-intensive services which are distinguished by their speed, flexibility, and scalability; see also this comparison. In conjunction with the petascope package implementing OGC standards, rasdaman represents the most powerful, flexible, and scalable geo raster server available.

The petascope plug-in to rasdaman, which is part of the distribution, offers high-performance, flexible, and scalable services on multi-dimensional geo raster data. Its Web services provide access to original or derived sets of geospatial raster information, in forms that are useful for client-side rendering, input into scientific models, and other client applications. Interfaces are strictly based on the open, interoperable standards of the ​Open GeoSpatial Consortium (OGC). Petascope implements all standards contained in the WCS suite for gridded ​coverages, i.e., raster data:

• the ​Web Coverage Service (WCS) Standard for simple data subsetting.
• the ​Web Coverage Processing Service (WCPS) Standard which defines a language for the extraction, processing, and analysis of raster data (see also this ​WCPS info page); petascope is the WCPS reference implementation.
• the ​WCS Transaction Extension (WCS-T) Standard for updating raster data offered by a WCS-conformant service.

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

Commercial Support

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.
