A grid tile is a contiguous area of grid cells distinct in some way from other such areas that together make up a grid mosaic. For instance, a tile may represent one side of cubed sphere, or an independently discretised region of an ocean grid that covers a particular body of water. A grid tile is composed of cells, which may be specified in different ways depending on their degree or regularity or uniformity:

  • Cells may be specified explicitly using sub-types of "cell"; the only such type available currently is the unstructured cell type.

Vertical levels are specified separately from the horizontal grid -- currently this is done using a vertical coordinate system.

The projection used (if any) is specified as a sub-type of "projection", e.g. Cube_Gnomonic, Stereographic and Tripolar.
