Tree Radar Roots Inspection
Most trees fall over because of compromised roots due to factors such as decay, severance during construction, and constricted growing conditions. At present, the only root inspection procedure is invasive – excavation – by either digging or use of a hyper-sonic velocity "air gun" that blows away the upper soil.
TRU offers a non-invasive method for roots inspection that provides the following information:
• 2D Planar Image of each Line Scanned showing Root Location (along the scan line) and Depth – "Virtual Trench "
• 3D Top-Down Image showing Root Layout at any desired Depth Slice – "Virtual Excavator"
The 2D planar view is called a "Virtual Trench " because it is the same view that would be seen if a backhoe were to dig a trench as long as the line scanned and an observer were to step down into the trench and examine the severed root endings to determine their location, depth, and diameter.
The 3D top-down view shows the image that would be seen by an observer in a bucket truck looking down
into the soil. The root layout is seen and along with its density in any direction from the trunk.
Advantages include:
• Non-Invasive
• Portable, via Battery Supply
• Minimal Set-Up
• Rapid Scanning – complete Ground Coverage in 30 to 60 minutes
• Penetration down to 39 in (1 m)
• Scan either Uncovered or Covered (penetrates concrete, asphalt, paving slabs) Soils
• High-Resolution Images of Subsurface Structural Roots
• Scan either Parallel Straight Lines on any Side of Tree or Concentric Circular or Semi-Circular Lines
• Scan in Tight Quarters in Urban Areas
• Easy to Use
• Accurate and Fast
