Hello everybody
Can someone please help me how to import a GEO TIFF file into Rhino
Many Thanks
Carlo
Hi Carlo,
As far as I know a Geo Tiff is a Tiff Image with additional reference coordinates. I use irfan view to convert them to jpeg images and then map them on a plane or a geometry like triangulated point cloud data which have the correct XY size (use texture mapping / planar mapping).
If you need the correct absolute YX position provided in the geo tiff, you can move the plane / geometry to the according position in a second step, however from my experience this can lead to problems with the display pipeline and in render engines which both do not like you to place objects extremely far from 0,0,0 sometimes.

Thank you, Andreas
Yes, my Tiffs are georeferenced. I thought maybe Rhino has an import function like in AutoCAD MAP or Civil3D. I will align the Tiff with reference points Planar with x y coordinates. Not so clean but Rhino apparently can not.
Thank you
Carlo
Hi Carlo, I find that Bison works well to import Geo TIFF files. It brings them in at the world origin.
In a previous workflow, I used QGIS to convert the TIFF to a point cloud.
HTH,

Hello,
It looks so cool.
I want to try but I think I met some difficulties in importing the Tiff file into grasshopper, so could you show me how to import it specifically?
Thank you.
Hi - did you download Bison? What’s the problem you are running into?

Hillshade Groningen.zip (1.2 MB)
I’m getting some strange results. With a very elongated vertical extrusion. My Grashopper setup is exactly the same as the one stated above. What could be causing this?
Same problem here. It looks like Bison can’t read the SWISSIMAGE Level 3 (10 cm) geoTIFF’s.
Bei einer Auflösung von 0,1 m weisen die Bilder folgende Eigenschaften auf:
• 3 Kanäle (RGB) zu je 8 bits, total 24 bits.
• Typ des GTiff-Formats: TIF Tiled (256 x 256 Pixel).
• Komprimierung: JPEG
• Resampling: -
• Pyramidenebene: 4
• Pixel ohne Daten (z.B. bei speziell zugeschnittenen Perimetern) haben den Wert 0, 0, 0

Hi -
I think Bison was last updated in 2018.
You could try with Heron that can be installed through the package manager in Rhino. @Brian_Washburn actively supports that application.

It looks like you are trying to import a Hillshade, which is meant for visualization purposes and does not contain elevation information. See a similar issue here:
I was able to download a tiff file from swissALTIRegio which imported just fine with Heron (and probably would work in Bison as well). I then tapped into the ch.swisstopo.images-swissimage layer of the wms.geo.admin.ch WMS GetMap service to get an aerial image to map on the topo.
