The specification of OGC (Open Geospatial Consortium) Web Processing Service (WPS) puts forward some uniform
interfaces to manage, browse, query and perform kinds of Geographic disposal. At present, most of the WPS services
implementing the interfaces can be called only based on HTTP GET/POST requests. This situation makes it difficult for
us to vastly composite, integrate and reuse these atomic services, through Business Process Execution Language
(BPEL) that has been very mature. This paper brings forward a method to better solve the problem, and, at the same
time, a composite process is carried out by chaining the atomic services of WPS to implement the complex Geographic
data disposal, which proves the effectiveness of the method.
