Does Grass GIS consider a 3D set as a single XY location, with a Z (elevation), and a property P. I have a dataset with vertical data points (stacked) in XY coordinates.

Each XY location has a Z and a Property. therefore i have as many XY as P.

I am wondering if I should slice the dataset into individual elevations (one data set for each Z), so that I can import and interpolate.

r3.in.xyz can take x, y, z and, optionally, value (property P) columns, so you don't have to slice the data set into individual elevations.
