Description

The SCMI data file format that is becoming common for ABI data shown in the USA's AWIPS system tiles data. The tiles are equal size (except for on the edges in special cases). There is already a StackedAreaDefinition but this expects "ribbons" or rows of AreaDefinitions. This doesn't work for these tiled datasets. I'd like a TiledAreaDefinition added that performs the same operations as the StackedAreaDefinition. If TiledAreaDefinition can be implemented by modifying StackedAreaDefinition then that is probably the easiest/cleanest solution.

Research direction

Start by reading the existing StackedAreaDefinition entry point and determine how it represents rows of AreaDefinitions. Define the corresponding behavior for equal-sized tiled SCMI/AWIPS data, including edge cases, and verify that the new TiledAreaDefinition performs the same operations on tiled datasets.
