Web Processing Service

Endorsed Standard
Description
 

A Web Processing Service (WPS) provides access to calculations or models which operate on spatially referenced data. 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 and use data exchange standards such as GML or GDAS.

This specification is intended to provide a mechanism 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.
