Create Accurate Maps with Blender GIS and QGIS

[@LCA-73]

The best tutorial I have seen so far on this rather complex topic. Many thanks for sharing your knowledge on this in such a clear and concise manner.

[@khairulhazmizaini1513]

I've been working with both QGIS and Blender separately and this is absolutely what I need for my workflow! Thank you for the tutorial. Keep enlightened us Nicko~

[@j.m5888]

A fantastic video, one that requires a couple of watches. I've been using QGIS and Blender independently for years, and never really got to grips with the BlenderGIS addon. Many thanks!

[@Cosmo_556]

Thank you oh so much for this, plus the way where you clicked was highlighted, the general editing, the clear instructions. Thank you so much. Like and subscribe VERY well deserved

[@CB_GAMES777]

Whoa, I'm accustomed to ESRI products but now i have another reason to use QGIS. 😂 This is awesome!

[@SowedCastelli]

I have no idea what you just did but I loved every second of Nicko. Thanks for the video. Another satisfied subscriber here.

[@rexsip4482]

Hello NICKO Thank you very much for your efforts ! I am a satisfied subscriber. Thanks to this subscription I didn't miss this video.

[@AshT8524]

This is crazy, Thank you for all your effort. 🤯

[@atropostr]

You are my hero. I was trying to solve vector coordinate errors in my Unity OSM project. Thank you very much

[@AnneLeschallier]

I want to say you are my hero too! thank you so much!

[@benjaminbaltar2952]

if you wan to follow along and the link to the esri xyz-files is not working, just open it in a browser and copy the link from there. the link posted in the video discription has a redirect from youtube in it and that did not work for me with direct copy and paste. thanks nicko for the vid! really good job 🙂

[@michaelsmusicinstruments9980]

great tutorial, interessting topics, thank you for your work 🧡

The first time I set the video speed at 0.75x almost sound normal and much easier to follow :)

[@SpicyAl3000]

That's great! Thanks dude :)

[@j.m5888]

Just for reference, with QGIS 3.40 Bratislava, an unknown Python error occurs when you save the custom CRS, crashing the program. Other people might experience this, so in my case it's not possible to continue.

[@gerardt.5172]

Very informative tutorial. I subscribed! Curious. Could you share the method used to achieve the synchronized animation between QGIS view on the left and Blender on the right from the time interval of 0:41 to 0:59?

[@WilfriedEBOLOETINGUE]

Nice job!

[@lewisgibson228]

Hi ! Great tutorial ! Just wanted to mention, when you change the CRS by going in the bottom right corner, it does a "on the fly" reprojection and not a "true" one (which you can get by using the toolbox). This usually has an impact when trying to merge data in QGIS but it might have implications when saving as a shapefile or when importing into blender but it's probably nothing

[@Nicko16]

Thanks for the comment, that is really good to know. I noticed that layers can have individual CRSs independent of the canvas CRS. Will be looking into it...

[@bojda_studios]

thank you very much

[@handlehaggler]

this exact video is posted on another channel called hydraulic engineering tutorial?

[@homemade_vancity]

Love this! Have had various levels of success and failure with other methods and add-ons for Blender 4.2 ... Using this method seems much more straightforward and the results seem better ..... Now a question or two; Is there way to bump up the texture/image resolution? Also, when I bring in the heightmap to Blender, it seems very not-smooth and rather pixelated, would subdividing the image first before applying the heightmap help do you think? Lastly, my first couple of attempts created this crazy stretched out side and I'm wondering if there is a clip method that adheres to the dimensions of the rectangle put on the map.

[@pertevdural4513]

how to add latitude, longitude grid lines on a map? how to change color of grid lines?

[@HeroesLeftInMan]

New to Blender, but using this tutorial to help me produce some geometry in some other software. I was wondering is there a node setup that could read the top faces of the building mesh, and flatten them. Right now the extrude moves up in Z fine, but inherits the slanted geometry from the shrinkwrap, and I'd prefer if the top of buildings were planar in Z but still having variable heights.

[@ДОМНАДОНУ]

Greetings. What other information can I download besides buildings and roads?

[@JamesBrett2008]

Thank you for the information Nicko, what are the pros and cons of Blender GIS/QGIS over Blender osm (blosm)?

[@nickkaverin]

Hi! I keep getting black height map. Everything is good until the export of the height map. It's always black :( Ah, you had black height map too. I think it's only for Blender GIS

[@rossisbudda]

Thanks to you

[@mercaruby]

How can I automatically export multiple high-resolution images from a specific area in QGIS, so they align perfectly like a mosaic? I'd like each image to be closer to ground level, rather than a single high-altitude shot. Is there an efficient way to do this? Very usefull video by the way, thank you very much!!

[@umangatang]

Another error (sorry great video!) When importing the DEM to Blender, "error: non overlap data". My DEM does not share the same geographic position as the land-sat image. This is strange because through all steps of the process, my user-created GCS was selected. I'm not sure how to fix the project or GCS of the DEM (or the land-sat, whichever is causing my headache).

[@j.m5888]

Has anyone else found that Blender scales all the imported files down by a huge factor? I have to scale up by 100,000 in order to get something close to the measurements in QGIS. Most of the steps shown in the video produce different results in Blender 4.1 and QGIS 3.40, maybe a version problem?

[@FlatterDeer]

Hi. Please tell me what I'm doing wrong? Cannot write raster. Error code: data source creation Cannot create new dataset E:\Area1.tif: Attempt to create 0x0 dataset is illegal,sizes must be larger than zero. Version 3.40. When exporting ESRI, this error occurs and the Extent on all axes (North, East, etc.) is 0.

[@ThoughtCog]

If I'm mapping an area in the USA, can I just define my coordinate system as one of the 1983 State Plane projections instead of making my own azimuthal projection?

[@bicukow]

is there a way to extract roads with thickness, not just curves? like cadmapper do (cadmapper also using OSM data as far as I know) I mean clean contours of roads

[@umangatang]

Interesting Error. If you draw a rectangle to DEFINE AREA, it wont be populated with coordinates, and therefore wont work when using the rectangle to define the area of imagery export. If you move the rectangles corners, it will populate them with coordinates. This gave me such a headache.

[@ishaanxgamer1836]

2:21 well the ESRI is only showing coordinates and not showing map in 3.38 verison

[@thomasvisonaa6201]

When I export the Height map it is inverted in Blender. How can I fix the problem. For the rest the video is amazing.

[@laurent5397]

At 8:33 minutes, when I choose to "calculate from" my "layer area", all the north, south, east, and west values reset to 0, and I can't export, even though I followed the tutorial to the letter. Thanks for this tutorial

[@Nicko16]

QGIS can be a bit buggy with the coordinate extents. It is worth restarting the program and possibly redrawing your layer extents.

[@redaboucetta1846]

@@Nicko16yes thank you that work after redraw the box

[@salyiohh]

is it possible to get also texture of building , thank you

👍

[@rothauspils123]

I know you can also get buiilding height data from OSM, if you use the map funcion of BlenderGIS and then later use get OSM, the buildings that have data will be the correct height, do you know how to get that data via QGIS?

[@Nicko16]

Wow that sounds great, I do not know how to do that, although likely someone in the comments might know...

[@lieslemmens7762]

You can't make height maps from countries like Japan I think. Because the maximum area for SRTMGL1 is 450,000 km2. The selected area is 13,021,912 km2. So no use.

[@nickkaverin]

Is it possible to extract the height map for other 3d software like Gaea?

[@erre8397]

Thank You Nicko16. Could you share what is "WKT Reference" actually doing ? Trying to understand this workflow and can the "WKT Reference" be use in other parts of the world?

[@Nicko16]

It is the description of a custom CRS, and yes, you can use it in other parts of the world. If you can get a latitude and longitude for a place you can insert it into the reference as per the video at 3:36

[@elbarzwalid7344]

Can u plz add how did u visualise tisso 's circle on that sphere ? in fact how did u even unwrap the shpere into a plane in blender ?

[@Nicko16]

Thanks for the message, its a bit complicated to explain in a message but could be a good separate video guide.

[@andreaslouvros7885]

When defining an extent to download with OpenTopography DEM Downloader, I am getting an area that is slightly tilted upwards, instead of the exact area defined. Is anyone running into this issue, or is it just me?

[@andreaslouvros7885]

I can workaround this problem, by initially getting SRTM data for larger area, and then exporting for the defined area. However, the exported height map is flat on the top and right parts and I don't see why is that.

[@epelfeld]

11:49 - Blender doesn't import height map...

[@stoobydoo2638]

What's wrong with using a CRS appropriate to Greece if they are already defined in QGIS and the Blender plugin?

[@trollenz]

Same question here

[@Nicko16]

Nothing wrong with using a Greek CRS if already defined, also nice to define your own to suit specific needs.

[@fahge]

Why didnt you use the height info off the buildings? Isn't there a way of using ir in blender?

[@Nicko16]

As far as I could tell, the shapefile that I used here, didn't have height data included in it. However, I believe that it is possible to have height data in a shapefile, yours might...many shapefiles do! Have a look at this tutorial: kzbin.info/www/bejne/jafMhZxmppd1pqMsi=VAw5I97oWkQ6Pghi

[@MrMcnamex]

after creating custom project qgis wkt projection it went straight to white screen. please anyone else have similar issues

[@Nicko16]

Creating custom CRSs can be a bit glitchy in QGIS, sometimes making a new profile under Settings > User Profiles > New Profile... can help.

[@francescocalvi7096]

I'm running through an issue where the height map seems to be coming out very pixelated. I seem to be getting the same issue when using only the BlenderGIS plugin to make the height map too. Is there just not enough data in some places in the world when using STRM 30m for height maps?

[@Nicko16]

Yes it is possible that there is just not very much info in some parts of the world, would be interesting to know how much detail you see in the raster in qgis. There are also other sources of height data available such as the ASTER global elevation dataset, so its worth looking around for better sources. Also double check that your mesh is subdivided, as the level of detail can greatly effect the height map

[@nicolas80340]

Hi man, great job and thanks for sharing your knowledge. I'm trying to get the whole map of the USA for a 3D job, could you do the same process but instead of selecting a rectangular area, select only the country in question? And if possible, could you do QuickOMS but for the division of the states?

[@madsthomsen9844]

So great! :)
