SimplifyBearing constructor.
public __construct ( float $bearingAngle )
$bearingAngle float

simplify() public method

1. calculate the bearing angle between the first two points p1 and p2: b1 2. calculate the bearing angle between the next two points p2 and p3: b2 3. calculate the difference between b1 and b2: deltaB; if deltaB is smaller than the threshold angle, remove the middle point p2 4. start again at (1.) as long as the polyline contains more points
