A contact region represents the connection between two grid tiles in a gridspec. The grid tiles are referenced using a fully qualified specification that includes the references to the mosaic(s) that the grid tile is a child of, as well a reference to the tile itself. This allows contact regions to be specified between tiles in different mosaics.
Contact regions can't be instantiated (used directly); instead there are two sub-types currently available:
- Overlaps can be specified where two grid tiles intersect. Overlaps take the form of an "exchange grid", which has the same number of dimensions as the two "parent" grid tiles.
- Boundaries can be specified where two grid tiles meet but do not cross. Boundaries have one dimension fewer than their "parent" grid tiles. The boundary type currently provided by the gridspec is suitable for tiles with logically-rectangular discretisations.
Note: the gridspec overview contains introductory and background information on the gridspec; more detailed information can be found in Balaji's gridspec document on the Earth System Curator website.
