Introduction

Welcome to the official documentation of the ZOO-Project, a powerful open source platform for creating and executing OGC-compliant Web Processing Services (WPS).

Note

This documentation is currently under review. Some content may be outdated, including support for certain platforms like Windows which is no longer maintained. Pages with obsolete material will be marked accordingly.

What is ZOO-Project ?

ZOO-Project is an open source implementation of the OGC WPS standards:

It provides developers with tools to wrap existing algorithms and libraries into WPS-compliant services, allowing them to be called over the web. These services can process geospatial and non-geospatial data in a flexible and scalable manner.

Key Features

  • Create services using C, Python, JavaScript, and more (up to 7 languages)

  • Integrate with major geospatial libraries: GDAL, GRASS GIS, OTB, CGAL, etc.

  • Process local or remote data

  • Build complex workflows by chaining services

  • Deploy services via a standards-based web API

Why Use ZOO-Project?

  • It’s modular, extensible, and highly interoperable

  • Easily integrates with web mapping clients and map servers

  • Lets you reuse your code with minimal changes and serve it as a web service

ZOO-Project Components

The platform consists of the following main components:

  • ZOO-Kernel — The WPS-compliant core engine written in C. Manages service execution and chaining.

  • ZOO-Services: — A growing suite of ready-to-use services built on robust open-source libraries (GDAL, GRASS, etc.).

  • ZOO-API: — A JavaScript server-side API to manage workflows and service orchestration.

  • ZOO-Client: — A JavaScript client-side library for sending WPS requests from web apps.

Open Source and Community

ZOO-Project is released under the MIT/X-11 license and maintained by a vibrant international community called the ZOO-Tribe.

It is an official project of the Open Source Geospatial Foundation (OSGeo), reflecting its commitment to open standards and collaboration.
