Thanks for this Nice video. Let's go for the next one.

As someone with a background in programming, I find this too be very useful. Thanks for the resource.

Thank youuu , im wondering if u can create more videos about symbolozing : create custom symbols , Strach Fill with Marker symbols etc…

Appreciate your content 👍 keep going...!

Thank you! Will do!

hello thanks for the video, I am not clear on the passage at minute 22, when you delcare the geometry. I am used to geopandas and so it is done: gdf = geopandas.GeoDataFrame(d, crs=“EPSG:4326”) instead with pyqgis i saw that it didn't declare any geometry, how does works? is there a default geometry or would it be best practice to declare one?

[@Dominator3727]

thank you

You're welcome

[@na2sprod421]

From your point of view, any examples of processes that could be automated with pyqgis?

[@geospatialschool]

The main thing would be repetitive workflows with multiple tasks.

How to use in Road features Database??

[@gtj1]

It seems it would be less time consuming and simpler for me to use the geoprocessing tools in Q-GIS to do this stuff instead of using Python. Am I missing the point? I enjoyed and appreciate the tutorial video. :)

[@geospatialschool]

If you're building a plugin to extend the functionality of QGIS or have a pipeline you need to run multiple times and get consistent results you'd want to automate it

Can you make a tutorial of how read/use the PyQGIS API documentation?

[@walterfrenguelli5421]

Hey man, there´s a book named "The PyQGIS Programmer's guide", wrote by Gary Sherman, maybe that's what you need

[@geospatialschool]

I also have a full course on PyQGIS that goes much more in depth in the documentation: geospatialschool.com/courses/qgis-python-scripting-with-pyqgis/

Hi geospatial school. I am interested in enrolling to "next level qgis program". Whether I ll get help during the course if I face problems?

[@geospatialschool]

Hello! I've tried to price the courses at an affordable price so that they are accessible to all. Because of that I can't offer 1 on 1 support. However, if you find issues with the course material, I will fix those.

[@kentthomas1045]

can PyQGIS be used from Python itself?

[@geospatialschool]

Yes. You must have the packages installed on your Python environment, which can be difficult to do, depending on your operating system. But you could make a copy the QGIS Python env and make changes to that.

[@djordjespasic2179]

Hi @@geospatialschool . Thank you for the very useful video! Do you mind if I ask which packages are needed to be installed? Is there some guide which shows how to run PyQGIS from Python itself, instead of using the QGIS Python console?

[@geospatialschool]

@@djordjespasic2179 You need to run PyQGIS using the Python interpreter that comes with QGIS. If you want to do GIS analysis with Python outside of QGIS then you're better off using libraries like geoapndas, gdal, rasterio, etc.

[@djordjespasic2179]

@@geospatialschool Thank you for the reply.

[@djordjespasic2179]

@@geospatialschoolThank you. I thought QGIS API capabilities were more powerful than external Python libraries, as QGIS itself relies on some of them altogether. But if there is not other way, then I appreciate the information.
