Types ¶
type DirectOptions ¶
type DirectOptions struct {
Do func(segment gpx.GPXTrackSegment) ([]gpx.GPXTrackSegment, error)
}
func DouglasPeucker ¶
func DouglasPeucker(maxDistance unit.Length) DirectOptions
Polyline simplification based on Ramer-Douglas-Peucker. Points are simplified when for the provided maxDistance.
func MaxDuration ¶
func MaxDuration(maxDuration time.Duration) DirectOptions
MaxDuration removes segments with a longer duration than the provided maxDuration
func MinDistance ¶
func MinDistance(minDistance unit.Length) DirectOptions
MinDistance removes segments with a shorter distance than the provided minDistance
func MinDuration ¶
func MinDuration(minDuration time.Duration) DirectOptions
MinDuration removes segments with a shorter duration than the provided minDuration
func MinPoints ¶
func MinPoints(minPoints int) DirectOptions
MinPoints removes segments with less points than the provided minPoints
func MinRadius ¶
func MinRadius(minRadius unit.Length) DirectOptions
MinRadius removes segments, if all their points lie within a given minRadius from the starting point
func RemoveStops ¶
func RemoveStops() DirectOptions
RemoveStops removes points that are assumed to have no relevant movement. See PauseSplit for a function that splits segments, if a pause is detected.
type FilterOptions ¶
type FilterOptions TransformOptions
FilterOptions hold a function that returns true iff a point should be included in the filter result
func TrimLeft ¶
func TrimLeft(maxRadius unit.Length) FilterOptions
TrimLeft cuts all points that are reached from the first recorded point within the provided max radius
func TrimRight ¶
func TrimRight(maxRadius unit.Length) FilterOptions
TrimRight cuts all points that are reached backwards from the last recorded point within the provided max radius
type SplitOptions ¶
type SplitOptions TransformOptions
func DistanceSplit ¶
func DistanceSplit(maxDist unit.Length) SplitOptions
A distance-based splitter that splits whenever two consecutive points have a distance larger than maxDist.
func PauseSplit ¶
func PauseSplit(radius unit.Length, minDuration time.Duration) SplitOptions
PauseSplit splits when previous points lie within the provided radius (from the currently viewed point) for at least minDuration. It waits with splitting until the next point (from the currently viewed point) would lie outside the radius. Different to RemoveStops, this function can be configured to not affect shorter pauses.
func TimeSplit ¶
func TimeSplit(maxStep time.Duration) SplitOptions
A time-based splitter that splits whenever two consecutive points have a time difference larger than maxStep.
type TransformOptions ¶
type TransformOptions struct {
/*
do must return true whenever a transformation should be performed at the provided index of a given track segment.
*/
Do func(segment gpx.GPXTrackSegment, index int) (bool, error)
}
TransformOptions is passed to transformation functions. It holds a function that decides whether a given transformation should be performed.
func NewTransformOptions ¶
func NewTransformOptions(do func(gpx.GPXTrackSegment, int) (bool, error)) TransformOptions
NewTransformOptions returns a new TransformOptions object that holds the provided do function.
