public static org.locationtech.jts.geom.LineString get(org.locationtech.jts.geom.LineString line,
                                                       double sigmaM,
                                                       double resolution)

Line gaussian smoothing. The position of each point is the average position of its neighbors, weighted by a gaussian kernel. For non-closed lines, the initial and final points are preserved.

Parameters:

line - The input line

sigmaM - The standard deviation of the gaussian kernel. The larger, the more smoothed.

resolution - The target resolution of the geometry. This parameter is used to filter the final geometry.

Returns:
