Thanks for the great tutorial. I really appreciate the explanation on increasing the detail of the model. Do you know how to use topography elevation lines by chance?
Sure. If you have a shapefile layer in GIS with elevation lines, you can simply import those. However, you need to add thickness to these lines using a solidify or wireframe modifier. However this wil create physical 3D elevation lines which you may not be the result you want. Another way would be to generate a raster image of the lines in GIS and import and project those on your model in Blender.
@@4dresearchlab97 Thanks for the quick reply! Have you thought about doing a tutorial on the subject? I haven't found any info about topo lines in 3D on RU-vid and would bet people would find it informative. My interest is for artistic purposes. Ultimately I want to create 3D topography of real-world areas in Blender and export vector data/imagery into a 2D vector program that I will use to set up compositions for output on a pen plotter.
@@johnyarnell6366 Yes, it would be a good subject for another tut. I had considered including them in this one but decided I'd digress too much. The BlenderGIS wiki shows some examples of using contour lines: github.com/domlysz/BlenderGIS/wiki/Make-terrain-mesh-with-Delaunay-triangulation. But its very limited.
Excellent tutorial thank you very much, it turned out very well, only I have problems loading the satellite image on the DEM, it comes out in black, any advice?
Great Tutorial, thanks a lot! Unfortunately, upon importing a .tif, I get stuck at the situation in 3:26 = a totally flat rectangle without any visible texture. Any advice what to do?
Can be various causes for this. Ensure the coordinate system of the tif matches the one used in Blender. Perhaps your tif is in a format that the BlenderGIS addon cannot read? You could try to load it in QGIS and export it again as geotiff.
The modifier only only allows a maximum of 6 subdivisions. Adding another one allows one to go beyond 6. This is not always necessary, but in this example, it effectively increases detail on the DEM.
Hi, thank you for the great video and great work! I have one question: I have seen your previous video (I suppose the previous one is that one where you show the installation procedure of Blender GIS...) but I have lost how you can save the georeferenced tif image that you use at 7:41...could you help? Thank you!
Why does the new blender version 2.91 has not been able to process the gis zip file properly... there is an error message that pops up after clicking on "basemap"
Thats not possible in Blender. But you could turn every contour line into thin mesh, using extrude and then assign a material with colour to the contour line.
You'll have to convert it to vector data, i.e. a regular shapefile with lines. You can import these in Blender, convert them to 'curves', and play with the curve settings to give them some thickness.
Its not really a straightforward process, because blender does not support exporting georeferenced models. You would need to do it in steps. First export the model as collada file, then In ArcGIS pro you can convert the exported 3D models to multipatch features and then georeference them manually. BlenderGIS stores the coordinates as offsets from the 0,0,0 scene centre of a blender file. You can use these coordinate offsets to georeference it in arcgis/scene. github.com/domlysz/BlenderGIS/wiki/Georeferencing-management
