     22It has to consider multiple details:
     23
     24- datacube dimension
     25- which axes are spatial
     26- Number of bands and types
     27- What is primary access pattern: spatial slices, or across non-spatial axes, or something inbetween?
     28 - gdal slicer imports 2D data organized in spatial slices, so it's very likely the access will be on spatial slices and the tiling should focus on the spatial axes
     29 - netcdf/grib slicers probably import 3D+ data, so there can be some extension of the tiles to the non-spatial axes
     30- Insitu: if original files are tiled/chunked (tiff and netcdf especially), the tiling in rasdaman should be a multiple of the chunk sizes
