Filling Out the Array 2D Map Data Structure
The <Array_2D_Map> class is a specialization of the Array_2D class. It exists on the assumption that PDS will develop map-specific requirements and software support that will be able to take advantage of assumptions and structures made for this data type.
|So far, none of that has happened, but there is a cartography discipline dictionary in active development. When that is released, this will become a much more interesting structural option. The Array_2D_Map is defined in the schema as a restriction of the Array_2D, but has the exact same definition.|
For an Array_2D_Map, follow the instructions for Filling Out the Array_2D Data Structure, with the following additional constraints/requirements:
- Use <Array_2D_Map> and </Array_2D_Map> rather than <Array_2D> and </Array_2D>.
