What data to collect to create a model on GPlates?

Hi, what data do I need to collect/process if I was to produce a model from GPlate? The data that I will be collecting is from Geotechnical Scans of a series of High Walls within an open-cut mine pit.
(Scanner: XR3 Terrestrial 3D Scanner)

Any suggestions on data gathering techniques that I could try or a method of processing 3D data for a model in GPlate?
