`3`	Discrete sampling geometry (DSG) “timeSeries” features.
`4`	Discrete sampling geometry (DSG) “timeSeriesProfile” features.
`5`	A 12 hourly time series at each latitude-longitude location.
`6`	Polygon geometry coordinate cells with interior ring variables.
`7`	Rotated pole dimension coordinate constructs and 2-d latitude and longitude auxiliary coordinate constructs.
`8`	A UGRID mesh topology of face cells.
`9`	A UGRID mesh topology of edge cells.
`10`	A UGRID mesh topology of point cells.
`11`	Discrete sampling geometry (DSG) “trajectory” features.

See the examples for details.

_func: function
