No, it's not. But I know Thierry... He is very interested by WKT Raster. Maybe rasdaman is a better solution for his SOLAP problems...

>Array DBMSs extend the collection types supported by DBMSs with the
>array abstraction as first-class citizen. As such, rasdaman offers a
>conceptual model based on multi-dimensional arrays of unlimited size
>over atomic and composite base ("cell") types. The rasdaman array
>algebra serves to describe data model, query semantics and processing,
>storage mapping, and optimization.

>A declarative, safe query language allows flexible retrieval in the
>style of SQL. ODMG-conformant C++ and Java APIs give programmatic client
>access. In the multi-parallel server, arrays are partitioned
>transparently into "tiles", i.e. sub-arrays, as units of storage. Each
>tile goes into a relational BLOB, optionally compressed. Tile size and
>shape can be chosen arbitrarily during object creation, and likewise the
>spatial indexing method used for tile lookup. The server architecture is
>based on "tile streaming" so that often only one tile per object needs
>to be kept in main memory at a time, thereby enabling small servers to
>process large arrays. On the other hand, transparent near-line tertiary
>storage support wipes out size limitations.
>
>The rasdaman group has extensively researched in optimization, resulting
>in techniques like query rewriting, pre-aggregation, just-in-time
>compilation of query fragments, and GPU utilization, all of which have
>been proven highly effective in performance evaluations. At ACM PoDS
>2007, Rona Machlin has termed rasdaman the "most comprehensive effort"
>in array DBMS.

>Rasdaman is in operational use in geo service applications run by both
>industry and governmental authorities since many years. For example, the
>French National Geographic Institute (IGN-F) maintains a dozen-Terabyte
>airborne image with rasdaman/PostgreSQL. Recently, the Open GeoSpatial
>Consortium (OGC, www.opengeospatial.org) has published the Web Coverage
>Processing Service (WCPS) standard which offers a geo raster processing
>language based on the concepts and experience of rasdaman.
