A root portion is represented as an edge (e couple of vertices) in the graph and is associated to different types of properties e.g. diameter. Recording the whole architecture necessitates a recursive pathway to be followed throughout the root system, with information about each link and segment being recorded at each stage of the measurment.

Minirhizotron cameras are expansive pieces of equipment (approx £15000), although they are quite simple systems to design. There are however very cheap pieces of hardware that can be used to build such equipments.
