Nice one! Glad to see you using Blender. A couple of years back I had an important project that required to learn QGIS from scratch, with no previous knowledge and your tutorials did it for me. Really nicely explained!
This video is very timely. I have been struggling through various ways to to this, but a demo done from the QGIS perspective (and by a experienced user) is super helpful!
Nice work!! Thank you for the "walkthrough". In R (programming language) you can also do it using the package "rayshader" alongside other packages like "sp", "sf" and "raster" with 10 lines of code is possible to achieve such a beautiful result.
Yes it is great called BlenderGIS. There is also a native Sun position plugin that allows you to have set the position of the sun by time/data/location on the world.
good morning, great video. in qgis I create the 3d model with the Qgis2threejs plugin and export it in gltf format. in blender I import it and I find the correct 3d model also with the Z coordinates.
amazing, you explain it so well, clearly you can make someone work on blender. thank you, im working a lot on architecture and we have to do many 3d mappings as it is the modern maps apparently. Thank you again!
Not sure why Blender calls that setting "air" exactly but it's volumetric lighting - you're changing the effect that light passing through different media might have (more/less water vapor or aerosolized dust, for example). Great tutorial!
Hi, thanks for this. Question. You mentioned having a global elevation dataset. Is that by chance part of QGIS or do I need to find a global dataset to use inside of QGIS?
You need to download that from Internet. And you may need to merge several files to get a complete global dataset in a resolution you are satisfied with.
There's also this approach 100% in blender. Disclaimer, he starts off easy enough but then goes nuts with textures and other vis tweaks. ruclips.net/video/Mj7Z1P2hUWk/видео.html
Hi, I tried your tutorial, but when I import the elevation image in Blender it appears upside down. I've never changed the software settings...can you help me to resolve this issue? Thank you for sharing these tips!
Hello, I had similar issues and this is how i solved them. First, I had to reverse the color ramp in Qgis so that the lowest value was white and the highest black. Then in Blender I had to lower my plane since it has higher than the actual elevation model. Hope I helped! 😊
Hej Klas! Tack för denna video! Jag har precis börjat jobba i QGIS och klurar nu på hur får jag in en 3D-modell i QGIS (har en modell i dxf-format och en i obj-format). Har du någon video om det? :-) Tack igen!
Hi Klas. Anyway I can get in touch with you over a mail? Its regarding the 3D population projection. I tried your blender tutorial but its not working for me so would you mind taking a look at the dataset? Thank you.
Excellent video. I've tried to follow your tutorial but my model has "stairs" and it is not smooth. Could you help with this situation? My elevation data is 10m pixel size. Thank you. Again nice video
Well, 10m pixels should probably not be used in scales under 1:50'000 (roughly), so if this is the issue you should "zoom out" or get higher resolution elevation data. It might be possible to resample the elevation data and interpolate the new values with a suitable. There might also be workarounds in Blender, but I'm not savvy enough to guide you there.
That is not only a resolution problem, it is related with the image format. Jpeg is really not good for displacement as it introduces that stairs artifacts, due to compression. You should use Tiff 16 bit at least and if the results are not good enough try Open EXR, although 32 bit could be too much in many cases. That is for the displacement. For texturing you can get away with Jpeg. Also, if you use Blender 3.x you get do do this stuff in Geometry Nodes, that starting with this version has Image texture nodes. This way you get to control the effect a lot better.
I have a used 4 core i7-3720QM from 2012 upgraded to 16 Gb ram and a 250 Gb SSD. It came with a AMD Verde graphics card. You really don't need a lot (if you run Linux). All is done with open source software and you trade limited computer performance for time spent. A better computer will be faster, but you can still do all the work with limited hardware.
If you are asking if you can do the GIS parts with ArcGis, then the answer is yes you can. If you can't get the correct raster image file formats, you can always convert them in another graphics package.

Please make a tutorial on that.
I would love a tutorial as well
So that would be the API right you're talking about?
what about python?
There is a GIS addon for Blender that can be downloaded and has added functionalities to translate GIS data into Blender easily.
Yes it is great called BlenderGIS. There is also a native Sun position plugin that allows you to have set the position of the sun by time/data/location on the world.
Yes, that is a very good solution. Use it myself
that plug in no longer really works... :/

Really nice video Klas! More QGIS & Blender.
Bra genomgång! Detta går även att göra via BlenderGIS - då tappar man inte koordinatsystemen - utan kan fortsätta att lyfta in shapefiler mm.

Yeah I also wondered why they called it AIR!
Muchas gracias!!!! hace tiempo que espera algo como esto. agradecido.
Nice... very nice. It's good to see an interesting approach to 3D presentation.
Your videos are fantastic! Thank you very much!
Sir pls make a playlist on different topic so that we can learn from basic function to advanced
Thank you
Hope you can make more tutorials on blender
I loved this video, it really helped me Thank you!!!
Amazing tutorial, just completed it and the my model looks awesome
Great workflow and thanks for showing.
Äntligen!!!
Thank you, will try it out and see what it out.
awesome content as usual!
Great Video. Mind to tell how do you get that open street map?
I am a novice user of GIS software and this is really cool.
Great Work!

Hello Klas, my digital elevation model sinks into the plane instead of sitting on top of it. Any suggestions on how to correct this?

When I import the image it doesnt load into the mesh....what do i do?

Du kan använda 3d modeller i obj som symbol för ett punktobjekt. Välj detta i 3d inställningarna för ett punktlaget.
Dear sir, how to make topographic maps in qgis like AMS map?
difficult to go from point a to B

What is your pc configuration when you created this art,
Kindly mention all details so that we get ideas about what we need to start this

@@KlasKarlsson thank you
how do you obtain elevation data?
One example, try google "GTOPO" (many sources)
A question, how could the plan be made but with a top view, is it possible?
There's a "top" view and you can switch the 3d view to orthographic if that is desired.
Can you do with ArcGIS Desktop and ArcGIS Pro?
If you are asking if you can do the GIS parts with ArcGis, then the answer is yes you can. If you can't get the correct raster image file formats, you can always convert them in another graphics package.
@@KlasKarlsson thanks very much
Adobe LightRoom Please!
No, because...
1. Not GIS
2. Not available on Linux
3. Not Open Source
The narration could be better. It would have been more engrossing had you rehearsed before recording.
