As part of the process metadata cleanup exercise, it would be nice to
standardize on a single term to use to refer to the data structure
represented by the GridCoverage class. In various contexts within GeoTools
this is referred to as a "coverage", a "grid", and a "raster".
External to GeoTools I think "grid" and "raster" are used more widely than
"coverage". And I believe the OGC definition of coverage allows for
vector-based polygonal and network coverages as well, so perhaps the term
"coverage" is too general to be used to refer to grids/rasters? Of course
some of the processes use "Coverage" in their names, but the metadata could
still use an alternate term to provide more clarity.
Is there any preference for using "grid" or "raster"?
