Examples of net.opengis.wcs11.InterpolationMethodBaseType

net.opengis.wcs11.FieldSubsetType
A representation of the model object 'Interpolation Method Base Type'. Identifier of an interpolation method applicable to continuous grid coverages. The string in this type shall be one interpolation type identifier string, selected from the referenced dictionary. Adapts gml:CodeWithAuthorityType from GML 3.2 for this WCS purpose, allowing the codeSpace to be omitted but providing a default value for the standard interpolation methods defined in Annex C of ISO 19123: Geographic information - Schema for coverage geometry and functions. @see net.opengis.wcs11.Wcs111Package#getInterpolationMethodBaseType() @model extendedMetaData="name='InterpolationMethodBaseType' kind='simple'" @generated
