[Qgis-user] connect QGIS with python

[Ujaval Gandhi]

You can install QGIS using conda
[https://gisunchained.wordpress.com/2019/05/29/using-qgis-from-conda/] along
with other required packages in the same environment. This is the easiest way to
ensure python dependencies are found correctly. If this is not feasible for you,
you can refer to the documentation
[https://docs.qgis.org/3.28/en/docs/pyqgis_developer_cookbook/intro.html#running-custom-applications]
which has pointers on how to set your PYTHONPATH


You can use all QGIS functionality, includig processing algorithms in a headless
mode. See my guide
at https://courses.spatialthoughts.com/pyqgis-in-a-day.html#writing-standalone-python-scripts

I also gave a talk recently and demonstrated the setup required to launch a
custom pyqgis algorithm from a web app. You can find the materials and video at

Good luck.
