The Web Processing Service (WPS) is an OGC standard that defines how to implement any geographic calculation or model (i.e. "processes") as a web service.

The WPS interface standardizes the way processes and their inputs/outputs are described, how a client can request the execution of a process, and how the output from a process is handled.

This site provides an introduction to WPS concepts, and describes the three WPS operations: GetCapabilities, DescribeProcess and Execute.
