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
