    9292'''...is much more simple than PGRaster and Oracle !GeoRaster'''. WKT Raster supports...
    93   * only one type (instead of two in Oracle Spatial: SDO_GEORASTER & SDO_RASTER). In WKT Raster there are no differences between a raster and a tile: a tile is a raster and a raster is a tile. A coverage is a table of tiles.
    94   * no metadata (like PostGIS).
    95   * no masks (you can build a mask as a band).

    9696  * no multiple dimensions (only two: x, y). Not to be confused with bands; WKT Raster DO supports multiband raster...
    97   * no pyramids (reduced resolution coverages can be stored as a separate layer).
