PyWPS and external tools ======================== GRASS GIS --------- PyWPS can handle all the management needed to setup temporal GRASS GIS environemtn (GRASS DBASE, Location and Mapset) for you. You just need to configure it in the :class:`pywps.Process`, using the parameter ``grass_location``, which can have 2 possible values: ``epsg:[EPSG_CODE]`` New temporal location is created using the EPSG code given. PyWPS will create temporal directory as GRASS Location and remove it after the WPS Execute response is constructed. ``/path/to/grassdbase/location/`` Existing absolute path to GRASS Location directory. PyWPS will create temporal GRASS Mapset direcetory and remove it after the WPS Exceute response is constructed. Then you can use Python - GRASS interfaces in the execute method, to make the work. .. note:: Even PyWPS supports GRASS integration, the data still need to be imported using GRASS modules ``v.in.*`` or ``r.in.*`` and also they have to be exported manually at the end. .. code-block:: python def execute(request, response): from grass.script import core as grass grass.run_command('v.in.ogr', input=request.inputs["input"][0].file, ...) ... grass.run_command('v.out.ogr', input="myvector", ...) Also do not forget to set ``gisbase`` :ref:`configuration` option.
