Description

Py-QGIS-WPS is an implementation of the [Web Processing Service](https://www.ogc.org/standards/wps) standard from the Open Geospatial Consortium based on the QGIS Processing API.

It also implements the [processes OGC REST api](https://ogcapi.ogc.org/processes/)

This implementation allows you to expose and run on a server: * QGIS Processing algorithms available on Desktop * QGIS Processing models and scripts * QGIS plugins having a Processing provider according to their metadata.txt file

It’s is written in Python and is a fork of [PyWPS](https://pywps.org/).

Requirements and limitations

Python 3.7+ only
Windows not officially supported
Redis server

Any WPS client should work with this implementation. For instance QGIS Processing algorithms are available in a web interface using [Lizmap WPS module](https://github.com/3liz/lizmap-wps-web-client-module).

Features

Asynchronous requests and parallel tasks execution
Execution timeout
Data expiration
Status API.

Installation

Install from source

Install from sources:
```
pip install -e .
```

Install from build version X.Y.Z:

make dist
pip install py-qgis-server-X.Y.Z.tar.gz

Running the server

The server does not run as a daemon by itself, there is several way to run a command as a daemon.

For example:

Use Supervisor. Will gives you full control over logs and server status notifications.
Use the daemon command.
Use systemd
