This schema defines the common type and elements used by the OGC web coverage server.
Describe the list of coverage layers served by the WCS. Use for the capabilities
This abstract class is the base class used to describe coverages provided by a WCS.
In case of discrete coverage, NONE must be used.
This type describe a layer serving a grid coverage
This type describe a layer serving a TIN coverage
This type describe a layer serving a multipoint coverage
To do
This type describe a layer serving a segmented curve coverage
This type describe a layer serving a thiessen coverage
To do
Description of the native domain set of the coverage
Use for temporal slices. The slices needs to be ordered from the lowest to the highest
Use for elevation slices
Describe the domain of a grid coverage
Describe the domain of a multipoint coverage
Indicates the number of points in the coverage
Describe the domain of a TIN coverage
Describe the domain of segemented curve coverage
Describe the domain of a thiessen polygon coverage
Describes the extent of the ThiessenPolygon coverage. Its boundary determines the boundaries of the outermost polygons in the network, which would otherwise be unbounded
Number of polygon or center in the coverage
Recommend a spatial extent for each queryable SRS
Asbtract type to define a domain extent
Describes the spatial extent of a coverage
Describes explicitly the elevation extent of the coverage
Describes explicitly the elevation extent of the coverage
Describes explicitly the elevation extent of the coverage
Define an interval along an axis
Describe a serie of elevations at regular interval
Describe a serie of elevations at regular interval
Describes a series of elevations
Describe explicitely the temporal extent of the coverage
Describe explicitely the temporal extent of the coverage
Describe a series of time instant
Describe a series of time instant at regular interval
Describe all the component of range set
This describes the range provided by a coverage.
Describe a range set component
Use for requesting a range subset in GetCoverage
Describe a spatio temporal object. The spatial and time are separed for the moment. Temporal needs to be integrated in the geometry in the future. See introduction of ISO 19108
List of codes that identifies interpolation methods for coverages.
This is the orientation of the grid axis. Natural orientation are right, up,front
This element provides an identifier for the format in which a layer can be requested from a service
Use as the identifier of the SRS in the request
This abstract class provides the common attributes for a layer. It could be reused by WMS, WCS and probably by WFS. A layer describes the underlying data and the processing performed by the service on this data (formatting, reprojection,...)
This type is provided mainly to define the (approximate if necessary) long/lat bounding box of the underlying data of a layer. This is mainly used for catalog search
A thesaurus can be associated with the list of keywords. It is optional. Mixed of thesaurus can be done by attributing the thesaurus for each keyword
A keyword can be associated with a thesaurus (RDF schema) providing the semantics definition. The value of the keyword will corresponds to the identifier of a ressource
Describe the format from which the content can be retrieved
Implicitly defines an unrectified grid, which is a network composed of two or more sets of equally spaced parallel lines in which the members of each set intersect the members of the other sets at right angles.
Position of the grid origin (0,0) in the indicated SRS
Grid offsets along each axis of the indicated SRS
Will be defined by CT workgroup in the future.
Represents a coordinate in a point grid. The coordinates must be integers.The ordering of the coordinate values must be the same as that of the elements of GridAxis.The coordinates values represents the number of offsets from the origin in the direction of a specific axis.
These are in the order of the GridAxis elements above
Represents a coordinate in a point grid as a string. The coordinates must be integers.The ordering of the coordinate values must be the same as that of the elements of GridAxis.The coordinates values represents the number of offsets from the origin in the direction of a specific axis. Coordinates can be included in a single string, but there is no facility for validating string content. The value of the 'cs' attribute is the separator for coordinate values, and the value of the 'ts' attribute gives the tuple separator (a single space by default); the default values may be changed to reflect local usage.
Provides grid coordinate values for the diametrically opposed corners of an envelope that bounds a section of grid. The order of the ordinates are the same than the axis described in the GridGeometry
Complex type to describe more intuitively a non rotated rectified grid
Binds the measurand to a value from a ObservableType registry. This should be described in a RDF file
Binds the measurand to a specific reference system. (can be a unit of measure, ordinal, nominal categories).
Value used to represent the category. The order is not significant.
Value used to represent the category. The order is significant
InclusiveLoweValue
ExclusiveUpperValue
conversion from sample to true value
Note that mixed category are autorized (oceanography for example use mixed qualititative and quantitative classification)
Set of values AT WHICH obervable is measured, or BY WHICH it is aggregated
Points or intervals along the axis where values are available (e.g., bands or age brackets)
Used for georeferenced coverage
