WPS4R is a solution for creating WPS processes based on annotated R-scripts. The code was developed in the FP7 projects UncertWeb and GeoViQua. The product website can be found at

WPS admins can upload scripts during runtime. They are stored by the WPS and made available immediately as processes for WPS clients.The scripts are executed by Rserve, which is an independent TCP/IP Server for R. It has either a local or a remote connection to the WPS and could also run on a different server.

A quick overview of WPS4R is available as a one page leaflet. wps4r-flyer-preview.PNG


  • Easily publish any R scripts as standardized, interoperable web processes
  • Flexible geospatial data input and output formats (based on Geotools)
  • Automatic metadata generation based on simple annotations
  • Service-side resources (files, directories)
  • Reproducibility: download original scripts files, session information and resources


Desktop or any client applications, such as web apps or services, can control WPS4R processes using the WPS service interface. Script developers can upload annotated scripts using the WPS Web Admin. The sript files and resources are accessible from the standardized process description.

Users and Deployments

Known production deployments

Testing deployments (via mailing list etc.)


ALERT! WPS4R is under (very) active development and the current release of the 52°North WPS might not provide the most stable functionality. Also, the tutorials in this wiki are potentially outdated. Please get in touch on the community mailing list if you want to use WPS4R! Thanks for your understanding. ALERT!


Source Code Installation

WPS4R is completely integrated in the source code of the 52°North WPS. To build and install it from source:
git clone
mvn clean install -Pwith-geotools

Binary Download

To download a 52°North WPS binary with WPS4R please use the latest successful nightly build:



For information about on-going development, getting the source code and contributing to WPS4R please see WPS4RDevelopment.


  • WPS 3.2.0
    • Integration Tests
    • R warnings are included in execute response
    • R sessionInfo() can be inspected in the admin console
    • Validity of process descriptions is shown in backend configuration
    • ...


The WPS webapp module contains several example scripts for WPS4R that should almost run out of the box (some R packages must be installed beforehand). Just activate the R repository in your wpsconfig file.



If you have questions regarding R scripts and the R integration, please contact the Geostatistics Community mailing list (Email: org, Forum: If your enquiry focusses on the WPS interface or the Java code, please direct your question to the Geopocessing Community mailing list (Email: org, Forum:

Either way, the developers will get your message and try to help you! Please take a look at existing discussions first, for example using the respective forums. Thanks!

support All information about the 52N mailing lists and forums:



To make sure Rserve is running, test your Rserve connection by typing the following command: telnet localhost 6311

You should get output containing "Connected to localhost.". You can return to the prompt by hiting the enter key.


"Cannot start Rserve automatically"

The command R CMD Rserve --vanilla is used to start R under Linux. Please check that on a command line. If it does not work either, please install r-cran-rserve, so install Rserve from the Ubuntu repositories instead of CRAN.
