A coverage (such as provided by the NetCDF format) that has more then
row/col/band information. Often used to capture raster information
that changes over time, or changes over height (forming a volume of
voxels).

Does that mean that changes of time form chronxels?

In anycase you get the idea, we need to provide a few more parameters
when getting back the band information (time or elevation in the two
examples above).

Normally we deal with 2D raster information, because we don't know the
"number" of extra dimensions for the data we give up and use the
mathematical notion "N" for an nD raster.

PS. perhaps Nixel? I like nixel
