OSGeo Project


PyWPS was initially started by Jachym Cepicky as part of his project ‘Connecting of GRASS GIS with UMN MapServer’ supported by the German Foundation for Environment. He began to work on this project with a scholarship by GDF-Hannover that went from April to September of 2006.

The first PyWPS site as a demo application was the WPS Demo provided by Help Service Remote Sensing.

The first presentation about PyWPS was held at the FOSS4G 2006 conference in Lausanne titled ‘GRASS goes to web: PyWPS’.

Around October of 2006, the project homepage was moved from Jachym’s personal homepage to a GForge server hosted at http://wald.intevation.org (maintained by Intevation GmbH`) to support their projects. Since then, PyWPS has its own mailing lists, source code repository and other necessary infrastructure for Open Source project.

In October of 2006, additional developers joined the development effort. Please see PyWPS Development Team for a list of current and past contributors.

2006-11-10: version 1.0.0 released

During November 2006, Lorenzo Becchi and Luca Casagrande started their work on a Web User Interface for WPS. They lunched two projects: WUIW and Embrio. WUIW should be a general web interace able to handle any WPS server. Embrio is bringing functionality of GRASS GIS to the Internet. WUIW and Embrio are part of the PyWPS repository.

2007-10-08: version 2.0.0 released

A new version improved stability, approached on the standard implementation and introduced the Python Process class to which methods can be used in process coding/implementation. A new WPS client project was launched as well as a WPS plugin for OpenLayers.

2008-11-06: version 3.0.0 released

A new version with improved stability, a new code structure, and a new implementation of OGC:WPS 1.0.0.

2009-06-01: version 3.1.0 released

Improves the 3.x branch. New generic JavaScript WPS Client library and more.


At FOSS4G-CEE, Bucharest we started to talk about a new implementation of PyWPS, which would use all the benefits of the current Python world. First lines were written at the codesprint after the conference.


Thanks to the Luxembourg Institute of Science and Technology, the first PyWPS workshop was organized in Luxembourg. The discussion on PyWPS-4 started.


Thanks to the Luxembourg Institute of Science and Technology, two developers actively worked on PyWPS-4. Also thanks to the Google Summer of Code, one student was accepted. PyWPS-4 also got a new REST interface.


PyWPS-4 branch was merged to official PyWPS repository as its master branch. PyWPS moved to http://pywps.org domain, finally!


PyWPS officially graduates as an OSGeo project.
