Webinar: Getting the most from your GPR Utility Data

Utility locators using GPR learn early that subsurface objects are indicated by hyperbolas, but they also learn that not all hyperbolas are utilities; they can be rocks, metal debris or other objects of lesser interest.

Two common GPR challenges that utility locators face daily are:

  • Too many targets– unraveling complex sites with many hyperbolas into usable utility locates can be difficult
  • Weak targets– the sought-after utility may not be the most prominent response in the GPR data and may be overlooked

In this webinar, we learn strategies, including the use of depth slices, GPS and interpretations, to get the most out of your utility-locating GPR data.
