Detailed Description

Merges multiple structure line data sets into a single line network.

The script accepts multiple line datasets derived with opalsGeomorph or gmpLineModeler, respectively, and merges all overlapping lines in to a single comprehensive 3D line network. First the overlap areas are identified and then corresponding lines in the overlapping areas are detected. Matching lines are merged by providing a smooth transition between the lines. The output is a single shape file containing the merged line network. Each line contains attributes indicating the quality of the line merging.

find_lines_at_ends()

def python.workflows.gmpLineMerge.find_lines_at_ends	(		line,
			polylineIndex,
			nrLines = 1,
			maxDist = 0.5
	)

Function that looks for corresponding at the respective ends of a line within the polylineIndex structure.

Args: line: pyDM.Polyline, the line for which corresponding lines are looked for. polylineIndex: pyDM.PolylineIndex, the index structure in which the lines are queried. nrLines: int, the number of lines that are desired to be found (closer lines are given preference to) maxDist: float, the maximum distance allowed (i.e. search radius around queried points)

Returns: tuple containting the lines at the end and start of the line, respectively.
