With the advent of the data grid came a novel distributed
scientific computing paradigm known as service-oriented sci-
ence. Among the plethora of systems included under this
framework are scientific workflow management systems, which
enable large-scale process scheduling and execution. To en-
sure quality of service, these systems typically seek to min-
imize workflow execution time as well as costs for slices of
data grid access. The geospatial domain, among other sci-
ences, involves yet another optimization factor, the accu-
racy of results. The relationship between execution time
