A Web Processing Service provides access to calculations or models
which operate on spatially referenced data. The data required by
the service can be available locally, or delivered across a
network using data exchange standards such as
GML or
GDAS. The
calculation can be 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.
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. The Web
Processing Service is targeted at vector GIS data, not at raster
image processing.
