The Accuracy of a Tree Root Radar Survey

A tree root radar survey is a non-invasive method of tree identifying. The GPR system collects the reflected signals from trees and shrubs. The data is processed by software to produce cross-sectional images of the trunk, as well as root density plots. The software provides quantitative results to certified arborists and other foresters. The data from a tree root radar survey are non-invasive and provide an accurate diagnosis of the tree’s health.

The measurements of root diameters can be obtained by comparing the results with measurements of the actual location of trees and shrubs. In the case of trees, the diameter of a tree’s root corresponds to the width of the hyperbola. In experiment III, the angle of the survey line affected the detection of tree roots. The angles ranged from 0deg to 15deg. The comparisons in table 2 illustrate the range of the survey lines.

The accuracy of tree root radar surveys is dependent upon the direction of the survey line. For example, the highest signal intensity is recorded when the radar wave front is orthogonal to the object. Conversely, a straight line intersects an object with a weak signal. The opposite is true for trees, as the roots extend from the center of the tree trunk. Thus, a circular survey line improves detection accuracy. The challenge will be to develop software to combine straight-line measurements with circular measurements.

The results of a tree root radar survey can be used to locate trees with shallow roots, which may pose a risk for property owners. The accuracy of a tree root radar survey is important for assessing the risk of a tree. In this way, an informed decision on removing an existing tree can be made. The accuracy of a tree root radar will help you make the best possible decision for your property and its health.

The 900-MHz antenna provides the highest level of accuracy in a shallow spectrum. Tree roots use the top 600mm of soil for rooting. During the experiment, we used different angles to assess the accuracy of the survey. Unlike the flurry of trees, the radars were not affected by the angle of the survey. In contrast, the horizontal direction of the tree’s roots was the most sensitive. The radial distance between the two plots was less than one meter.

The GPR results have been shown to be highly accurate and useful. The accuracy of tree root radar surveys is also dependent on the direction of the survey line. The roots grow in different directions from the center of a tree’s trunk, and a circular survey line helps to achieve the most accurate results. Using a circular line to determine the position of the tree’s roots improves the efficiency of a GPR. Another challenge in tree root radar survey is developing software that can use both horizontal and vertical measurements simultaneously.
