News about the Open WPS Platform

An introduction to ZOO-Project

ZOO-Project is a Web Processing Service (WPS) implementation written in C, Python and JavaScript. It is an open source platform, released under MIT/X11 Licence, which implements the WPS standard edited by the OGC

ZOO-Project provides a developer-friendly framework for creating and chaining WPS compliant Web Services. Its main goal is to provide generic and standard-compliant methods for using existing open source librairies as WPS.

Open WPS platform

WPS Server

ZOO-Kernel is a powerful server-side C Kernel able to manage and chain WPS services

WPS Services

ZOO-Services is a collection of ready to use WPS services based on existing libs.


ZOO-API is a server side Javascript API for creating and chaining WPS Services.

WPS Client

ZOO-Client is a client side JavaScript library for interacting with WPS Services.


ZOO-Kernel implements the WPS 1.0.0 and WPS 2.0.0 specifications of the Open Geospatial Consortium and runs on GNU/Linux, MacOS X and Windows™ platforms.

ZOO-Kernel is able to execute WPS Services written in C/C++, Fortran, Java, PHP, Perl, Ruby, Python, C# and JavaScript.

ZOO-Kernel is able to interract with GIS engines such as GRASS, OTB or SAGA-GIS. So no more coding is needed!

Run your code through WPS compliant web services.

OGC WebServices Publication

MapServer support: automatc result publication as : WMS/WFS/WCS

Asynchronous request

GetStatus: ongoing status informations.

GetStatus also available as a service for WPS 1.0.0!

Nested inputs/outputs (2.0.0)

Sample nested outputs.

Better support in the upcoming 1.7.0 version!

ZOO-Kernel security section

ZOO-Kernel is now able to pass any security parameters required that has been received in the initial WPS request and that should be send when accessing secured resources.

ZOO-Kernel HPC Support

The schema has been provided by IRD, IRSTEA, Geolabs, Noveltis.

The ZOO-Kernel now supports remote execution of Services!


ZOO-Services is a growing collection of ready to use WPS services built on top of reliable open source libraries such as GDAL, CGAL and more.

A ZOO-Service is a couple gathering a source code to execute and a ZCFG or YAML file which describes the Service and the needed input/output.

In the upcoming 1.7.0 version, the metadata informations of a ZOO-Services can also be stored in a structured PostgreSQL database.

Turn your code into a WPS service easily.

 def HelloPy(conf,inputs,outputs):
        outputs["Res"]["value"]="Hello "+inputs["a"]["value"]+" from Python"
        return zoo.SERVICE_SUCCEEDED

Available services

500+ ready to use WPS

GSoC2016 available on github!


ZOO API is a server side Javascript library designed to simplify the creation and chaining of WPS processes.

Uses Mozilla Spider Monkey as JavaScript engine.

ZOO.Process server side classes.

Call and chain your WPS Services the simple way.

Example 1/2 (MapMint 1.0)

Example 2/2 (MapMint 1.0)


ZOO-Client is a client-side JavaScript API which provides simple methods for interacting with WPS server from web applications.

It is helpful for sending requests to any WPS compliant server and to parse the output responses using simple JavaScript.

ZOO-Client relies on modern JavaScript libraries and can be seamlessly integrated in new or existing web applications.

ZOO-Client uses logic-less Mustache templates for creating well-formed WPS requests

ZOO-Client integration

Example 1/5 (SAGA Demo)

Example 2/5 (OTB Demo)

Example 3/5 (MapMint 2.0 Client)

Example 4/5 (MapMint 2.0)

Example 5/5 (MapMint 2.0 / Manager)


Bring WPS to Open Data Catalogs
