     3This page tries to inspect many of the different types of N-dimensional (spatiotemporal) gridded coverage topologies that could be stored in `rasdaman`, accompanying every case with GML WCS responses upon both trimming and slicing.
     4
     5Despite some cases might rarely have a practical real-world example, here we want to give examples for as many allowed geometries as possible.
     6
     7All responses will highlight the `domainSet` of each [http://schemas.opengis.net/gmlcov/1.0/coverage.xsd coverage], which will all translate to some [http://www.schemacentral.com/sc/niem21/e-gml32_Grid.html gml:Grid] rectified or referenceable subtype.
     8In case of mixed rectilinear/curvilinear geometries, a non-standard so-called `ReferenceableGridByArrayAndVectors` type ![1] will be used, for a more compact and convenient GML description.
