here a slate (not comprehensive, but likely covering all considered by W3C
- gridded coverages:
    - by dimension: 1-D through 4-D (climate people also consider 5-D)
    - by grid type:
        - regular grid (equidistant spacing ("resolution"), such as ortho imagery)
        - irregular grids (grid lines have individual spacing per axis, such as
timeseries often have)
        - warped grids (grid points sit anywhere in space, but still
topologically isomorphic to a grid)
        - sensor grids (geo position of grid points determined by sensor model,
usually some involved non-linear algorithm)
- non-gridded coverages:
    - point clouds
    - (rest likely not of interest here)
