WCS 1.0.0 DescribeCoverage response may contain TemporalDomain #159

Closed echeipesh closed 4 years ago

WCS 1.0.0 DescribeCoverage response contains domainSet element

WCS 1.0.0 Specification Section 8.3.2

The first of these elements, domainSet, describes the domain of the coverage offering – that is, the locations in space and/or time for which values or measures are available (whether by direct retrieval or by spatial interpolation). GetCoverage requests should retrieve meaningful data from the Coverage Offering if their spatial or temporal constraints (BBOX or BoundingBox, TIME, or Time) intersect the locations or times described in domainSet.

domainSet must include a SpatialDomain (describing the spatial locations – whether discrete or continuous – for which coverages may be requested), a TemporalDomain (describing the time instants or intervals for which coverages may be requested), or both.

This issue to connect updated data model for coverage to WCS DescribeCoverage response such that available metadata is well represented.

Note that in case the source layer will be a GeoTrellis spatiotemporal layer the temporal ranges of populated layers will need to be written to the AttributeStore by user, as GeoTrellis layers can not efficiently query for availability of time slices, only attempt to read things at specific time interval.

Reference

TM_Position and TM_PeriodDuration are defined in ISO_19108
