  8. 8. GeoRadar Utility Mapping Technology Principles Feb 2011 All rights reserved to IDS 8
  9. 9. GeoRadar Utility Mapping Technology principles (1/4) The radar transmits a small pulse of EM wave through an antenna The reflected energy from the discontinuity is captured and received by the antenna. The time delay contains information on the target depth The depth and the resolution are related to the antennas frequency, to the power transmitter and to the dielectric properties of the ground. Feb 2011 All rights reserved to IDS 9
  10. 10. GeoRadar Utility Mapping Technology principles (2/4) The GPR is a method developed for shallow, high-resolution, subsurface investigations of the earth. GPR uses high frequency pulsed electromagnetic waves (from 25 MHz to 2,000 MHz) to acquire subsurface information. GPR Principle Feb 2011 All rights reserved to IDS 10

  16. 16. GeoRadar Utility Mapping Regulations Regulations allows the setting of standards for appropriate and professional engineering procedures. American Society of Civil Engineers: (ASCE/C-I 38-02, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data). JUPEM: Standard Guideline for Underground Utility Mapping (AM/FM Technical Sub- Committee & National Mapping and Spatial Data Committee). NORMA ITALIANA CEI 306-8: Italian Regulations for performing preliminary surveys with Ground Probing Radar before laying underground utilities and infrastructures. KADASTER: The Ministry of Economic Affairs of Netherland has decided that Kadaster will take over the operational activities from KLIC starting on 1 October 2008.

  17. 17. GeoRadar Utility Mapping SUE Standard SUE allows cost effective location and depiction of the exact location of underground utilities through the interaction of technology, civil engineering and geophysics: utility mapping at appropriate Quality Levels utility relocation design and coordination utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.

  18. 18. GeoRadar Utility Mapping Why use GPR technology? GPR can locate any pipes: metallic and no-metallic, (PVC, concrete, etc.). GPR allows the optimization of excavations / destructive testing and reduce their costs and associated Risks. GPR complements the surface inspection with an economic, objective, documentable, precise (quantitatively interpretable) image of the underground providing 100% of project area coverage.
