I’m pretty sure there are some custom nodes that can get you the translation directly, but there are a handful of ways to go about “calculating” it.
You should be able to find some examples in the forum. This is the first one I found after a quick search. You’re essentially just getting the location of the survey point and using that (or its inverse) to get the vector to (or from) the translation.
That being said, depending on what you’re trying to do with your graph, you may not need to do any of this. The Data-Shapes output is likely the format you want if you’re trying to relate this surface to its location within the project coordinates.
