Hi Petros,

Since you are examining WPS, I recommend ZOO-Project (http://zoo-project.org/), from the MapServer family, which supports writing services in many languages (C, Python, PHP, JavaScript, ...), as well as creating GDAL/OGR services, and even outputting dynamic MapServer WMS services on-the-fly (meaning: it creates a MapServer mapfile that serves the result through a web map service).

But here is a great working example:

- MapServer is serving the background data (spatialite database) here through GeoJSON/WMS and the application leverages ZOO-Project to execute spatial commands (buffer etc).  Give it a try at https://ms4w.dev/zoo-project/demo/

If you check Developer Tools in your browser, you will see at call to the ZOO loader (https://ms4w.dev/cgi-bin/zoo_loader.cgi) and sending a request such as https://pastebin.com/nhpyc2jx

And the response from MapServer in GeoJSON: https://pastebin.com/G2VEVYRF

All thanks to the power of ZOO-Project WPS !!!

Hope that opens doors for you.

-jeff
