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.

1. A computer-implemented method for conflating a base dataset with a secondary dataset, the base dataset including a plurality of base polylines and the secondary dataset including a plurality of secondary polylines, the method comprising:
defining a locker boundary around each of the plurality of base polylines; identifying a plurality of initial matched segments and a plurality of initial mismatched segments for the plurality of secondary polylines, wherein each portion of the plurality of secondary polylines that is included within one of the locker boundaries is defined as an initial matched segment and each portion of the plurality of secondary polylines that is not included within one of the locker boundaries is defined as an initial mismatched segment; identifying a segment split within the plurality of secondary polylines, the segment split corresponding to an initial matched segment that extends from at least one initial mismatched segment defined along the same secondary polyline; comparing a segment length of the segment split to a threshold length; and if the segment length is less than the threshold length, re-defining the segment split as a mismatched segment.
