owsInterpolationMethod.xsd 2006-09-01 This XML Schema Document defines interpolation method elements and types, used by the OGC Web Coverage Service (WCS) version 1.1 and intended to be included in OWS Common version 1.1. Copyright (c) 2006 Open Geospatial Consortium, Inc, All Rights Reserved. Interpolation method(s) that can be used when continuous grid coverage resampling is needed. Spatial interpolation method used when client doesn’t specify one. This default interpolation method should be the recommended or normal method for this coverage range field. Unordered list of identifiers of other spatial interpolation methods that server can apply to this range field. When the default interpolation method is “none”, no other methods should be listed. Identifier of a spatial interpolation method applicable to continuous grid coverages, plus the optional "null Resistance" parameter. Identifier of how the server handles null values when spatially interpolating values in this field using this interpolation method. This identifier shall be selected from the referenced dictionary. This parameter shall be omitted when the rule for handling nulls is unknown. 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. Reference to a dictionary that specifies allowed values for interpolation method identifier strings and nullResistance identifier strings. This reference defaults to the standard interpolation methods dictionary specified in WCS 1.1.0.
