== WPS workflow idea ==

Zewnętrzne mapy rastrowe mogą być zlinkowane do GRASS-a za pomocą {{cmd|r.external|version=70}}. Oszczędza to czas i przestrzeń dyskową. Dodatkowo, nie ma już potrzeby przechowywania wyniku w wewnętrznym formacie GRASS-a; z {{cmd|r.external.out|version=70}} mapy wynikowe są bezpośrednio zapisywane w formacie obsługiwanym przez bibliotekę GDAL.

'''Prygotowania'''

GRASS can be used in an automated way by just defining a set of variables. See here for [[GRASS_and_Shell#Setting_the_variables|GRASS and Shell]] settings and [[GRASS_and_Python#Creating_Python_scripts_that_call_GRASS_functionality_from_outside|GRASS and Python]].

'''Data flow example'''

Skrypt może wyglądać jak poniżej:

# register GeoTIFF file in GRASS database:
r.external terra_lst1km20030314.LST_Day_1km.rst.tif out=modis_celsius

# define output directory for GRASS calculation results:
r.external.out /srv/gisoutput/

# do something (here: extract pixels > 20°C), write output directly as GeoTIFF:
r.mapcalc "warm.tif = if(modis_celsius > 20, modis_celsius, null() )"

# use the result elsewhere
qgis /srv/gisoutput/warm.tif

== Linking to WPS server ==

A framework has been developed to make the integration of GRASS GIS 7 in WPS server as easy as possible. The
framework is called '''wps-grass-bridge''' and is available here:
* wps-grass-bridge: http://code.google.com/p/wps-grass-bridge/
This framework support currently PyWPS, ZOO WPS and is used by 52North WPS server. Many GRASS GIS 7
modules can be attached out of the box.

There are currently several other WPS implementations which use GRASS as GIS backbone:
* PyWPS: http://pywps.wald.intevation.org/
** PyWPS and wps-grass-bridge connector: http://code.google.com/p/wps-grass-bridge/wiki/PyWPS_Integration
** [http://pywps.wald.intevation.org/gallery/index.html Gallery] (live examples)
