What this patent covers
A method of building a map from ground-penetrating radar scans collected along many separate passes. Where the paths of travel overlap, the readings from those passes are combined rather than treated separately, which yields a higher-resolution or more accurate picture of what lies below the surface than any single pass would give.
US 12,681,168 is a utility patent titled “Method of Generating a Map Based on Ground Penetrating Radar Scans”, invented by Christopher Green, Rafiou Oketokoun and David Cist and assigned to Geophysical Survey Systems, Inc..
The application was filed on August 3, 2022 and granted on July 14, 2026, 3 years, 11 months later.
It is one of the patents our firm has obtained in the Electrical — Sensors & Measurement area.

Abstract
Disclosed herein is a method of generating a map based on ground penetrating radar (GPR) scans including receiving GPR data corresponding to multiple path of travel of one or a plurality of moving devices and/or surfaces. Some of these paths of travel overlap at least some others and some of these paths of travel are independent of one another. Where overlapping is determined, GPR data is combined to form a higher resolution and/or more accurate determination of physical properties of a subsurface. Further, the resolution can increase with each scan of a particular area and the technology can be used in conjunction with a separate positioning system like a GPS and/or replace the separate positioning system when the resolution is sufficiently high for a portion of the surface.
