the rasdaman technology is the leading Array DBMS, from both industrial and scientific viewpoints.
At ACM SIGMOD, rasdaman has been characterized as "most comprehensively implemented" Array DBMS by an independent Array DBMS expert not involved in any way in the project.
The Open Geospatial Consortium (OGC) raster query language standard, Web Coverage Processing Service (WCPS), has been crafted along the concepts of rasdaman.
