Welcome to rasdaman!

This is the website of the open-source rasdaman ("raster data manager") project. Rasdaman 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.

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 flexibility, speed, and scalability.

The petascope plug-in to rasdaman, which is part of the distribution, offers ​OGC standards based services on multi-dimensional geo raster data. Petascope implements the OGC Web Coverage Service (WCS) standards for gridded ​coverages, i.e., raster data: ​Web Coverage Service (WCS) for simple data subsetting. rasdaman will be the WCS 2.0 reference implementation; ​Web Coverage Processing Service (WCPS) 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; ​WCS Transaction Extension (WCS-T) for updating raster data offered by a WCS-conformant service.

Meantime a ​GDAL rasdaman driver is available; soon ​MapServer integration, and ​PostGIS integration will be available, see our planning.

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