Module Separate points by direction
Separates points by direction. Direction is determined as average direction of three consecutive points A, B, C. If the angle between the directions of A-B and B-C is higher than given tolerance angle the point is dropped. This module has been designed to separate GPS tracks recorded by tractors while preparing a field.
