org.opengis.coverage.Coverage
A function from a spatial, temporal or spatiotemporal domain to an attribute range. A coverage associates a {@linkplain DirectPosition position} within its domain to a record of values ofdefined data types. Examples include a raster image, polygon overlay, or digital elevation matrix. The essential property of coverage is to be able to generate a value for any point within its domain. How coverage is represented internally is not a concern. For example consider the following different internal representations of coverage:
- A coverage may be represented by a set of polygons which exhaustively tile a plane (that is each point on the plane falls in precisely one polygon). The value returned by the coverage for a point is the value of an attribute of the polygon that contains the point.
- A coverage may be represented by a grid of values (a {@linkplain DiscreteGridPointCoverage Discrete Grid Point Coverage}). If the coverage is a {@linkplain ContinuousQuadrilateralGridCoverage ContinuousQuadrilateral Grid Coverage} using {@linkplain InterpolationMethod#NEAREST_NEIGHBOUR Nearest Neighbour} interpolation method, then the value returned by the coverage fora point is that of the grid value whose location is nearest the point.
- Coverage may be represented by a mathematical function. The value returned by the coverage for a point is just the return value of the function when supplied the coordinates of the point as arguments.
- Coverage may be represented by combination of these. For example, coverage may be represented by a combination of mathematical functions valid over a set of polynomials.
Metadata
The legacy {@linkplain Specification#OGC_01004 OGC 01-004} specification provided some methods forfetching metadata values attached to a coverage. The {@linkplain Specification#ISO_19123 ISO 19123}specification do not provides such methods. Implementations that want to provide such metadata are encouraged to implement the {@link javax.media.jai.PropertySource} or{@link javax.media.jai.WritablePropertySource} interface. @source $URL$ @version ISO 19123:2004 @author Stephane Fellah @author Martin Desruisseaux (IRD) @author Wim Koolhoven @author Alexander Petkov @since GeoAPI 2.1
