System and Method for Conflating Datasets

摘要

In one aspect, a computer-implemented method for conflating a base dataset with a secondary dataset may generally include defining a locker boundary around each of a plurality of base polylines of the base dataset and identifying a plurality of initial matched segments and a plurality of initial mismatched segments for a plurality of secondary polylines of the secondary dataset, wherein each portion of the secondary polylines that is included within a locker boundary is defined as an initial matched segment and each portion of the secondary polylines that is not included within a locker boundary is defined as an initial mismatched segment. The method may also include identifying an offset parameter defined between a first initial matched segment and its corresponding base polyline using a three-vertex approximation and, if the offset parameter exceeds a predetermined offset threshold, defining the first initial matched segment as a mismatched segment.
