This is a simple demo app written using PyWPS 4. It has been tested with QGIS 1.8.

The app depends on PyWPS and several other libraries that are listed in requirements.txt. You can install them with pip:

$ pip install -r requirements.txt
$ pip install -e git+https://github.com/jachym/pywps-4.git@master#egg=pywps-dev

For Debian based systems you will need to install GDAL with:

$ sudo apt-get install python-gdal

For Windows systems install you need to install Shapely and GDAL by using Python Wheels. If you have Shapely already installed you might have to uninstall it and installed as a Wheel for it to work:

Download the corresponding wheel for Shapely: http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

Download the corresponding wheel for GDAL: http://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal

$ pip install wheel

$ pip install Shapely?x.x.x?cpxx?none?win_xxx.whl

$ pip install GDAL?x.x.x?cpxx?none?win_xxx.whl

Simply run the python file:

$ python demo.py
