CV _ DiscreteSurfaceCoverage
A discrete surface coverage (c1ass CV _ DiscreteSurfaceCoverage ) consists of a
collection of surfaces. In most cases, the surfaces that constitute the spatiotemporal
domain of a coverage are mutually exc1usive and exhaustively partition the extent of
the coverage
For example, a coverage that represents com fields typically has a spatial domain
composed of a surface with irregular boundaries where no interpolation is feasible.

CV _DiscreteSolidCoverage
A discrete solid coverage (c1ass CV _DiscreteSolidCoverage) is a coverage III
which its domain consists of a collection of solids.
For example, an ocean body or an atmospheric volume could be represented as a
CV _ DiscreteSolidCoverage with a range of attributes such as temperature and pressure at each vertex.
