QGIS User 0010 - Geometry Generator

This is a basic look at the QGIS Geometry Generator style.
I'll "convert" between geometry types and create new ones, but this is only the beginning of what is possible with this extremely powerful styling.

Wow, that was cool. Thank you very much Klas

Your channel is a gem, thank you for sharing this!

Thank you for sharing this valuable lesson. I have been searching how to convert lines to points to do a network analysis and this saves me time.

Great stuff, nice way to generate styles shapes/symbols on the fly without creating a new layer

[MarkPercival]

Thanks Klas. I've used it for simple buffers but this added complexity will be great. Thanks for the channel.

Thank you Klas! Nice introduction to the geometry generator I wasn't aware of

[robinkohrs]

Thanks a lot for these videos!! Wish I had them discovered before...

Thanks Klas! This video is for me very useful. Until now I did not know the "Geometry generator" tools. They will certainly help me in my work

Nice video Klas! I was wondering if i can create a line next to my line feature indicating where it starts and ends and display the length (available as one of my fields)on it at the same time. Since my line is made of many segments the expression that im using (make_line) creates a straight line between these points. Do you know how could i approach this problem? segments_to_lines creates a line for each segment and i want a simple line. My main goal is to get displayed the length of a line (multiline and therefore with curves). Id appritiate any advice :)

Hi how would I be able to use this to do a live dissolve and sum by category (attribute) text label... to check total population by district as I assign a district code to blocks for example

[ludovicofrate]

Thank you for sharing. In particular, the make_polygon on point geometry could be useful to produce demers cartograms.

Thanks for this tutorial, especially for MilkyWay stars:) <3

[iltonmsfreitas]

Thanks Karlsson! Great!
How can I get points starting from the "most northerly" vertex, regardless of the order of the polygons vertices?
Could you help me about this question?

[gabde]

Can I dimension the azimuth of the sides of a polygon layer? Thank you so much for the tutorial

[georisiko]

Hi Klas - thanks for your great channel, I have learned alot from you! May I kindly ask you how to rotate the rectangles/squares by using a field attribute ? The rectangles needs to have fixed dimensions, lets say 3x6m. And yes, my dataset is a point.shp with "angle" as one of the attributes. Many thanks, Steinar (Norway)

[Chenshi]

do you know how to do a dashed line around a polygon, but to make sure that in every corner the dashed line has never a gap?

[caswellndlhovu]

Great Tutorial, how do you save the created geometry as a new layer.

[marceljunioregondi]

Klas thank you for the tutorial on geometry generator. Thou, am not picking much on it. Like how do you get to know the different functions. Or is it like excel that you keep getting the functions as you use them. Thou, would be good if there is a library for the geometry functions and what they do.

[Chenshi]

demonstrate "closest_point" and "distance" would be nice. maybe between a street and all assigned buildings.
