GENERATION OF BUFFER ZONES FOR BURIED ASSETS

摘要

A method on a computing device for defining a buffer zone around a buried asset at an above-surface location is provided that solves the above-described problems. The method includes receiving and storing buried asset data points, wherein each buried asset data point comprises a geographical coordinate and a precision data value corresponding to the geographical coordinate, for a buried asset, wherein the buried asset data points correspond to signals that were detected and read from the buried asset at the above-surface location. The method further includes generating a two dimensional area comprising a buffer zone by defining circles around geographical coordinates of the buried asset data points, wherein a size of each circle is based on the precision data value of the corresponding buried asset data point, and defining trapezoids that connect adjacent circles.
