This dictionary specifies the standard values fo interpolation types specified in the WCS 1.1 specification, based on ISO 19123. In addition, this dictionary specifies definition URNs in the "ogc URN namespace for these interpolation types. Interpolation methods standard values Identifier of nearest neighbour interpolation defined in Annex C of ISO 19123: Geographic information - Schema for coverage geometry and functions. nearest urn:ogc:def:interpolation:OGC:1.0:nearest Identifier of bilinear interpolation defined in Annex C of ISO 19123: Geographic information - Schema for coverage geometry and functions. ISO 19123 specifies two-dimensional bilinear, biquadratic, and bicubic interpolation types. When also interpolating in the elevation dimension of a 3D CRS, the 3D extensions of these interpolation types shall be used. linear urn:ogc:def:interpolation:OGC:1.0:linear Identifier of biquadratic interpolation defined in Annex C of ISO 19123: Geographic information - Schema for coverage geometry and functions. ISO 19123 specifies two-dimensional bilinear, biquadratic, and bicubic interpolation types. When also interpolating in the elevation dimension of a 3D CRS, the 3D extensions of these interpolation types shall be used. quadratic urn:ogc:def:interpolation:OGC:1.0:quadratic Identifier of bicubic interpolation defined in Annex C of ISO 19123: Geographic information - Schema for coverage geometry and functions. ISO 19123 specifies two-dimensional bilinear, biquadratic, and bicubic interpolation types. When also interpolating in the elevation dimension of a 3D CRS, the 3D extensions of these interpolation types shall be used. cubic urn:ogc:def:interpolation:OGC:1.0:cubic Identifier that no interpolation is available; requests must be for locations that are among the original domain locations. none urn:ogc:def:interpolation:OGC:1.0:none Identifier that nulls in the input grid(s) have no effect on the interpolated value; resampling uses only non-null valued cells. full urn:ogc:def:nullResistance:OGC:1.0:full Identifier that interpolated value is Null if any one input value is Null. zero urn:ogc:def:nullResistance:OGC:1.0:zero Identifier that interpolated value is Null if half or more of the input values are Null. half urn:ogc:def:nullResistance:OGC:1.0:half Identifier that resampling treats nulls differently from any method described above. other urn:ogc:def:nullResistance:OGC:1.0:other
