Georeference an image in 3D (VCS)

[PeterGebhardt]

Hi Everyone, we work in archaeology and are looking into a workaround to georeference stratigraphic profiles. We create large profiles using photogrammetry and export them. Now we try to georeference them in 3D, in a local scene using X,Y,Z. But even with an Vertical Coordinate System (VCS) activated the georeferencing option in the raster toolbox is greyed out. Anyone has a workaround? I mean its just referencing a picture in 3D, this should be possible right? Any help welcome 🙂

Cheers

Peter

If you can, I would recommend using GLB (or gITF) instead of OBJ for better performance. I believe 3DF Zephyr will output GLB.

For reference, I have worked with GLB files approaching 200MB in size, geologic outcrops spanning meters, with sub-cm detail in the textures, and still had decent performance in Pro on a mid-range GIS workstation.

Once georeferenced, I often convert the 3D Objects to SLPKs for more efficient rendering, and to share via ArcGIS Online.

Hi Peter, thank you a lot for your help. We'll be using gITF or OBJ. Probably OBJ due to our data manager can only archive OBJ files. But some tweaking the texture and we got ourselves a good result.

Maybe CloudCompare can be of some help here like: Georeference your LIDAR or Point Cloud with ArcGIS Pro and CloudCompare. You can drag and drop OBJ files directly in CloudCompare.
