- This video is part of a series created for the ARCHON skills workshop '3D landscape visualisation in Blender'.
Shortcuts for the BlenderGIS addon:
- ‘B’ to select area to zoom to
- ‘G’ to search a location
- ‘spacebar’ to switch layer
- ‘L’ to lock the view, while still enabling zooming to receive higher resolution tiles
- ‘CTRL’ and scroll to zoom without loading new tiles
- ‘E’ to export the current view to a new plane in Blender - Наука та технологія
Hello. Thanks for this video, it explains very well the process. I have one issue though. I am comparing measurements in Google Earth and the Blender GIS output and getting different numbers. I measure a surface in GE and it is 509.21 meters, in Blender it is 724.009meters. Would you know what is causing this difference? My Blender is set to Metric.
Hi, you're correct. Its a known issue: github.com/domlysz/BlenderGIS/issues/81. But this is not a bug of the Blender GIS addon, but inherent to using the web mercator projection, which is a global map projection with significant distortions on a local level. Google maps/earth is automatically applying a correction to the measurement after projection. BlenderGIS is not.
If you want accurate measurements, you'll need to use coordinate systems and projections that are optimised for a certain region of the earth. National grids are often used by individual countries, which you can use. However, since the addon does not 'reproject' maps that are in one coordinate system to another on the fly, and the imported google earth data is always in this inaccurate projection, you'll need to prepare your map in external software like QGIS. Or, and that's another option, install the GDAL extension to get this reprojection functionality. This is a bit of a technical procedure, but not too hard. It is explained here: github.com/domlysz/BlenderGIS/wiki/How-to-install-GDAL
@@4dresearchlab97 Hi. How do I use a national coordinate system? Why would I need to reproject what data from Google?
Can I not use data from a national coordinate system and pair that with open topology data for heights? where does Google come into this in such a case?
Thank you for your tutorial!
@@4dresearchlab97 I've installed GDAL, but the distance is still wrong
This was very helpful. Thank you!
Very cool. Thanks for sharing
With the L lock, and rolling the mouse wheel, I found it will export stubborn larger land masses, it just requires multiple presses of the E key. Likely one would benefit with more ram going for a 1 to 1 scale zoomed out too far. Curious what the largest texture you created from your exports. Thanks
Just amazing! Thank you so much
Any idea on how can we rotate the map before exporting? It would be more efficient for me to have a specific orientation of the basemap prior to exporting it.
Great video!! Thank you so much truly!
Oh my God I've using the GIS add-on wrong for soo long! Thank you!!!
Great vid! Thanks!
Very helpful! understandable and thorough
Question: I understand the tiles and the zoom levels of the photo imagery. I notice that the height information from the Open Topography server is also tiled. Are the tiles - their size and resolution - linked? Can I get more height detail?
I need more height detail because I aim to model rather small regions.
Many thanks for your effort!
Thanks for this tutorial!
As far as I've noticed BlenderGIS does create a map based on the current size of the viewport window but what I would like to get is a perfect squared map. Do you know how to achieve this?
thank you really helpful, hat is the extension that allows you to work ith layers using different coordinate reference systems?
hello i love this plugin i have a question, what are the licences behind the image ?
Do you know if it possible to import 3D objects from blender into ArcGIS Pro using Blender GIS?
Wow, a very nice tutorial. I've just liked and subscribed to your channel.
I have several data points of floating air balloons in latitude, longitude, and altitude. Could you show how to plot these balloons as objects in the Blender GIS 3D map that you just created (assume the balloon coordinates are within the 3D map)? Thanks!
Hi, thanks! I discuss importing custom point data, assign altitude and an object to them in another video: ua-cam.com/video/t9CH-cg8scc/v-deo.html The workflow for you would be the same.
@@4dresearchlab97 Wow, I followed your link and watched it. It's the exact feature that I was looking for. Thanks again for your quick reply!
Brilliant very clear tutorial, thank you very much 4D Research Lab!! 😌🙏🌐
Thanks for the nice words
can you create heightmaps with this addon
It says can not reach opentopography at the moment. I saw in the logs that the target router isn't accepting the connection. It says not allowed (Windows error 10061). I tried to see if the port is open but for that I need the IP which I don't have. What can I do?
really wish you could add a website to the srtm list, as getting 2m terrian would be really good
Is there a way to export georeferenced terrain data and use it in autocad dwg file?
Excellent tutorial, thanks - - but if you can turn UP your volume a bit,... thanks again.
The Georender i have are way darker than hat i see on the screen, i can't find where i could tune this, or why it's darkening .... Any idea please?
Do you know how to create and the export elevation in tif files from GIS ?
theres a problem with the size. theres a section thats 60m long irl, but in blender it appears to be closer to 90. the google earth measurements are also correct, so it must be a problem with blendergis. is there any way to fix this?
I keep getting an error Overpass error when attempting to "get OSM" building data.
Try switching to camera view after applying elevation then rotate the view port gizmo. You won't find the map anymore :D. It get super small object which cannot be focused in the view port.
I don't understand why it's happening or It's happening only to me. Also I lost texture resolution when I reopened my project.
Plz is that support with cities like Egypt
How can we crop the boundary of the area we want from a base map?
muito bom mesmo
thanks for the video GRATEFUL IT HELPED ME A LOT FOR MORE VIDEOS LIKE THIS!!! CONTINUE LIKE THIS, STAY WITH GOD TAKE CARE OF YOURSELF CHANNEL AND SUBSCRIBERS 😇😇😇❤❤❤💫💫💫
Hi, I'm kinda a blender noob. Do you know a fast way to create 3d roads from the road lines that Blender GIS creates from OSM?
you end up building some roads?
@@F1WestCoast Sadly, no
After I load SRTM data everything goes off..please help
Is there a way to improve elevation data of such huge plane with high zoom level? Because I am looking to use a very detailed height map with textures for a map mod for American truck sim, to make al the roads at the correct height in the game editor itself, but also having an incredible view at far distant mountains. This would improve the mapping accuracy and work flow enormously
The SRTM satellite data that is imported has a maximum resolution of 30 or 90 meters. If you need more detail, you will have to find another elevation map of your area. Some regions in the world have been lidar scanned and this data may be freely available. If not you can get a drone with decent camera and capture the data yourself ;)
@@4dresearchlab97 awesome! Been looking around for some Alaskan elevation data, but I sadly cannot find any. Because I need a URL source link set in the settings for it right?
Does anyone know how its possible to pull down the highest resoltion version of the satellite image textures when using blender gis while showing a wider area than the scale would usually show at the chosen zoom level?
I used google earth pro and you can save to image to 8k .. I am getting better results but it’s not perfect .. selecting the same area you do with Gis.. but it’s. A higher quality image
can you help, when I open a base map no image appears, just the grey plane, i turned of the grid and it was the same
I guess you're in the wrong shading mode in Blender. Check the little spheres on the top right of the 3D viewport. You may be in solid shading (= grey by default). Switch to 'material preview'. Or, still in solid shading, click on small downwards arrow next to the last sphere, and look for 'texture'. Select this.
After selecting the map and clicking "Georender" the camera view is blank :( been trying to figure out how to set up camera for two days now
I had the very same problem. If you still haven't resolved it and gave up 1 year ago, I found out why: Camera clipping distance. The camera view is not scaled for such large scale objects by default, and you need to adjust it to 500m, 1000m, 2000m etc. depending on your needs. It's the "Clip start/end" in "Lens" in the camera settings.
Took me way too long to figure it out.. They should mention that in tutorials that are not camera-specific since by default, you get a blank image otherwise.
hi, is this better than Blender OSM?
When I hit "OK" (5:54), nothing happens, it takes me into the Z axis view and nothing shows up.. even after turning grid off, nothing's there, am i missing something..?
Im using blender 4 and when I go to bring a basemap, only the scroll works, all menus and buttons freeze... every once in a while I see it say in the gis map section, building a mozaic when I try and click a button a menu... what gives?
The plugin doesn't work in blender 4.0, so you'll need to download and use an older version (3.6.9 worked for me)
How can you export the SRTM map as a hight map? :)
You can find the location of the srtm map on your harddrive in the texture properties tab in blender (with the srtm object selected). Open this map in QGIS, and right click > export. Save it as geotiff and select 'rendered image'. This transforms the 32 bit floating point srtm tiff to an 8 bit tiff file. You can use that output as a regular height map.
@@4dresearchlab97 Got it! Thank you :)
Hey man nice video ❤️
Iam facing a problem in ( Get OSM >> Ways )
When i Click On ( Get OSM )
Option
I select everything eg:. building, highway,railway etc.
After clicking Ok it shows
Error and it says ( Over pass query Failed, Check Logs for more infos ) please help me to remove that error. 🙏 It will be very helpful
Hi, unfortunately it gives me an error (Blender 3.0 / windows 11) Cannot reach Open Topography web service. Check logs for more infos. Do you have any idea to solve this problem? Would love to hear from you. kind regards, Angelika
Why my gis odd-on doesn't have NASA data?
Hello, I recently installed this addon and tried to make a nice landscape with it. Unfortunately, when I attempted to get the height map with the SRTM button, blender threw an error called a traceback error. I have no idea what this is or how to fix it. Is there a work-around? Thanks.
Hi, such error can have many causes. It often means there is a setting wrong. But I can't tell exactly without seeing the exact content of the error. But I'd advise you to check out the Blender GIS wiki. Ensure you followed the exact steps of installation and setting up. github.com/domlysz/BlenderGIS/wiki/Quick-start If that doesnt help, try the issues section on the Blender GIS addon page: github.com/domlysz/BlenderGIS/issues Good luck!
@@4dresearchlab97 I followed the installation guide that you presented, as well as another UA-cam channel, and the GIS addon page. I don't think that that is the problem. I did however find a thread on github forums were someone had a similar problem. One person mentioned that the error was caused by python GDAL not being installed. Could that be my problem as I do not have it installed?
@@messo_9732 Well, I doubt it. For basic functionality you do not need GDAL. GDAL is a library only needed when you want to reproject your data on the fly. So, when your data is in one georeference system, while your blender scene is in another. If you happen to have set your scene georeferencing to a system that doesnt match the one of the SRTM, then you could get an error like that.
@@4dresearchlab97 I still don't know what the cause was but I fixed it by removing a reinstalling the addon, that hadn't worked before but now it did. Thanks for your help anyway.
@@messo_9732 How did you fixed the error. I have same tracebase error.!
Je klinkt Nederlands, dus ik probeer het gewoon even. Dit werkt allemaal super, maar voor Nederland is een nauwkeurigheid van 30 meter niet echt realistisch. Nu is er natuurlijk het actueel hoogtebestand die om de meter een hoogte puntje heeft. Is die als SRTM data sorce te koppelen aan de GIS plugin?
Hoi Klaas, zeker! Dat is mogelijk. Je moet dan het betreffende AHN kaartblad downloaden also geotiff (downloads.pdok.nl/ahn3-downloadpage/). Deze kan je importeren als 'georeferenced raster' via het BlenderGIS import menu. Ik leg de algemene workflow uit in deze video: ua-cam.com/video/t9CH-cg8scc/v-deo.html
@@4dresearchlab97 Weer een stap dichterbij. Bedankt voor de uitleg en linkjes. Ik heb ook het andere filmpje gevolgd met een gedownloade TIFF via die link. Als CRS voor die ED50 /UDM zone 33N gekozen en DEM as displacement texture, maar krijg als resultaat een paar enorme spikes over de hele breedte van het vlak. Is er nog iets waar ik op moet letten bij het importeren van die AHN3 TIFF's? Moet ik een andere referentie kiezen? Ik probeerde al de Amersfoort / RD New, zonder goed resultaat. Of is de gedwonloade TIFF van 500MB simpelweg te groot.
EDIT: Het lijkt er op dat Blender iets raars doet met de TIF file. In de browser ziet hij er normaal uit, maar in blender krijg je een strepen patroon. Zie link voor een screenshot: photos.google.com/album/AF1QipPD8RN__4YSzJZ1JuP1zmRY1q1Onlk4Z4CQ8lGn/photo/AF1QipM0Aou8pKOcyvpbqDcc-dNcXh-ByaYFRPoejy7p
@@Kamiklaasie Ja, je kan beter wel Amersfoort/RD new als coordinaatsysteem selecteren. Geen ED50/UDM zone 33. In de video werk ik op een andere geografische locatie (italie), en in een ander coordinaatsysteem. Maar het coordinaatsysteem heeft geen invloed op die spikes. Dat heeft denk ik te maken met extreme uitschieters in de AHN data. Je moet dan eigenlijk eerst de AHN data (de geotiff) naar een GIS programma halen (QGIS, ArcGIS), de uitschieters filteren en weer exporteren als geotiff. Als de uitschieters alleen aan de rand zitten hoef je niet eens te filteren, maar kan je de zo tiff clippen ('uitsnijden') dat de waardes erbuiten vallen. Zoek op youtube/google voor uitleg als je niet precies weet hoe dat werkt.
It's April 2022 and the few last tries with BlenderGIS I get connection error with the elevation server. I tried to create a personal account and add my own API-key at the end, but even that didn't work for me.
Does anyone have a solid way to update this to 2022, being able to load elevation data? Thanks!
Hi, this is new to me as well. Perhaps you tried this already, but this worked for me: 1. go to opentopography.org, create an account and request an API key. 2. In Blender > add-on preferences > elevation server (select opentopo 30 or 90) > edit > replace portal.opentopography.org/API/globaldem?demtype=SRTMGL1&west={W}&east={E}&south={S}&north={N}&outputFormat=GTiff with portal.opentopography.org/API/globaldem?demtype=SRTMGL1&west={W}&east={E}&south={S}&north={N}&outputFormat=GTiff&API_Key=123YourAPIKeyHere123
Repeat the steps for the other opentopo elevation server (so the 30 or 90 one, depening on which you modified first).
If this doesnt work, check for typo's!

@@4dresearchlab97 Much appreciated!
I basically tried that exact method before, but your link above worked better. It works now, with my API key.
I'm not exactly sure what the difference is between what I was trying and your format above, but at least it works here too now!
Many thanks!
@@4dresearchlab97 Thanks for letting us know about this process. It actually worked. :) Keep going.

can we directly enter the coordinates of a given location?
During searching after pressing G, yes
cant get any SRTM elevation data, keeps whining about not being able to reach opentopography web services
it doesnt let me zoom when i hit L, zoom level stays the same?
No, your camera stays the same, since you locked it with L, the zoom is being incresed, you just don't see it. But you should see a text line in the upper left showing that it is downloading a larger number of tiles with each scroll step.
Hope madara will use this in the next ninjia war
