LineStringMatcher

public LineStringMatcher()

Method Detail

isApproximatelyStraight

public static boolean isApproximatelyStraight(com.vividsolutions.jts.geom.LineString line)

Computes whether a LineString is "approximately straight". This is the case if the line has a width of less than STRAIGHT_WIDTH_PERCENT percentage of it's length

Parameters:

line -

Returns:

true if the linestring is approximately straight

directionLineSegment

public static com.vividsolutions.jts.geom.LineSegment directionLineSegment(com.vividsolutions.jts.geom.LineString line)

lengthDifferencePercent

public static double lengthDifferencePercent(com.vividsolutions.jts.geom.LineString line0,
                                             com.vividsolutions.jts.geom.LineString line1)

isOrientationCompatible

public static boolean isOrientationCompatible(com.vividsolutions.jts.geom.LineString line0,
                                              com.vividsolutions.jts.geom.LineString line1)

Computes whether two linestrings are "orientation compatible". This is the case if they have a relative angle of less than 60 degrees.

Parameters:

line0 -

line1 -

Returns:
