cell refinement<DGGS>
process of subdividing parent cells into descendant child cells using a specified refinement ratio and suite of refinement strategies
Note 1 to entry: Iterative application of cell refinements creates a hierarchy of descendant discrete global grids.
Note 2 to entry: Cell refinement methods may result in child cells that each have a single parent or that have multiple parents.
