The Campus Tree Radar Unit (TRUTM)

 

1 | 2

 

How the TRUTM works: An air-filled trunk (hollow), or partially air-filled incipient decay zone, are excellent reflectors for detection by ground penetrating radar (GPR) systems. Data are taken on and around a tree trunk at several uniformly spaced above-ground heights to give a comprehensive view of internal structure.

Root systems scans and mapping

 

 

Electromagnetic differences between tree roots and the surrounding soil provide the necessary contrast and reflection properties that are detected by GPR. Concentric circular scans around trees provide enough detail of root systems to map specific root locations as well as determine overall distribution and root system integrity, which is important for tree stability and health.
