Web Processing Service (WPS): Request for Public Comments

Please note: This Request is closed. The documents listed below have been adopted by the OGC Technical and Planning Committee. These specifications are under control of the specification Revision Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.

The Open Geospatial Consortium (OGC) is contemplating adoption of a technology called Web Processing Service (WPS). OGC invites public comment on a candidate specification that will soon be presented for approval by OGC members as an OpenGIS(R) Implementation Specification. The purpose of this Request for Public Comment (RFPC) is to obtain comments on the proposal for technologies and needed interfaces required for Web Processing Service (WPS). Documentation of this draft specification can be downloaded here:

This document specifies the interface to a Web Processing Service (WPS). A WPS can be configured to offer any sort of GIS functionality to clients across a network, including access to pre-programmed calculations and/or computation models that operate on spatially referenced data. A WPS may offer calculations as simple as subtracting one set of spatially referenced numbers from another (e.g., determining the difference in influenza cases between two different seasons), or as complicated as a global climate change model. The data required by the WPS can be delivered across a network, or available at the server.

This interface specification provides mechanisms to identify the spatially-referenced data required by the calculation, initiate the calculation, and manage the output from the calculation so that it can be accessed by the client. This Web Processing Service is targeted at processing both vector and raster data.
