OGC coverage data and service standards overview diagram


Coverage specifications (with adoption status)

Schema location for Core, extensions, application schemas:

Coverage data model:
  • core:
    • GML 3.2.1 Application Schema - Coverages ("GMLCOV"), version 1.0.1, OGC 09-146r2: adopted
    • Coverage Implementation Schema 1.1 (candidate standard)-- backwards compatible next version of GMLCOV; key features:
      • renamed GMLCOV to CIS to better reflect contents of the standard (too many people believed GMLCOV is just a GML encoding, while it actually defines interoperable coverage structures in a format-independent way)
      • CIS 1.1 is backwards compatible to GMLCOV 1.0, and does not require any change to WCS 2.0
      • instead of the cumbersome grid distinction of Rectified / Referenceable Grid, various axis types are defined: non-referenced, regular, irregular, etc; these axis types can be combined arbitrarily in a coverage (eg, regular, rectified Lat and Long axes together with an irregular time axis)
      • support for grids as per SensorML 2.0
      • coverages can be partitioned into sub-coverages while still acting as one (eg, in a WCS GetCoverage request)
      • prepared for JSON support (next version)
  • format encoding extensions:

WCS service model:
