The Web Coverage Processing Service (WCPS) defines a language for filtering and processing of multi-dimensional raster coverages, such as sensor, simulation, image, and statistics data. The Web Coverage Processing Service is maintained by the Open Geospatial Consortium (OGC). This raster query language allows clients to obtain original coverage data, or derived information, in a platform-neutral manner over the Web. == Overview == WCPS allows to generate pictures suitable for displaying to humans and information concise enough for further consumption by programs. In particular, the formally defined syntax and semantics make WCPS amenable to program-generated queries and automatic service chaining. As the WCPS language is not tied to any particular transmission protocol, the query paradigm can be embedded into any service framework, such as OGC Web Coverage Service (WCS) and OGC Web Processing Service (WPS). The current WCPS version is 1.0. The standards document,〔Baumann, P. (ed.): (OGC Web Coverage Processing Service (WCPS) Language ), OGC document 08-068r2, 2008〕 available from the OGC WCPS standards page,〔(OGC WCPS standards page )〕 presents a condensed definition of syntax and semantics. In addition, there is an introduction to the concepts along with design rationales.〔Baumann, P.: (The OGC Web Coverage Processing Service (WCPS) Standard ). Geoinformatica, 14(4)2010, pp. 447-479, DOI 10.1007/s10707-009-0087-2〕 Currently, WCPS is constrained to multi-dimensional raster data, but an activity is under work in OGC to extend it to all coverage types, i.e., digital geospatial information representing space-varying phenomena as defined in OGC Abstract Specification Topic 6: ''Schema for Coverage Geometry and Functions''〔( OGC Abstract Specification Topic 6: Schema for Coverage Geometry and Functions, OGC 08-126 )〕 (which is identical to ISO 19123) and refined to a concrete, interoperable model in the OGC ''GML 3.2.1 Application Schema - Coverages'' (GMLCOV) Standard.〔(OGC GML Application Schema - Coverages, OGC 09-146r2 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Web Coverage Processing Service」の詳細全文を読む スポンサード リンク
