[Gvsig_english] Development Tutorial

[michael gould]

The geoprocessing routines are wrapped and exposed as services as described
by the OGC WPS specification (we have done this with sextante routines). The
client i.e. gvSIG (in the future) calls each remote service --and might even
chain services-- instead of executing locally. Obviously not very efficient
if huge data files must be moved around, but an interesting model to
consider for cases where the data stores are in the same location as the
services anyway (for example ESA).

Could you elaborate a bit on how you would envision that?
