New technology at Terra Nostra: the ground penetrating radar

Soon Terra Nostra will be able to use the ground penetrating radar (GPR) to study tree roots. The big advantage of this method is that it is a non-destructive method, here the soil is not disturbed and thus, roots and cables are not damaged. The GPR has been tested extensively by Terra Nostra.

In collaboration with Sharon Hosegood Associates from the UK the GPR has been tested at two different locations in the Netherlands. The objective was to test the accuracy of the GPR results ompared to the presence and location of roots in excavated trenches. Both test showed that GPR results are very accurate in predicting the location of roots. The results of one of the tests will be presented at the international conference ‘Trees, People and the Built Environment III’. The GPR is applicable for root surveys, Tree effect Analysis, transplantation studies, damage appraisal, and monitoring of root growth. Results are visualised in both 2D and 3D. At the end of April 2017 more will be known about when the GPR will be operational. For questions and information please contact Henry Kuppen.
