Frequently Asked Questions
Why should I close the gap on a circular GPX route?
GPS navigation units (Garmin, Wahoo) will not recognize a course as a complete circuit if there is a gap between start and finish points.
How does FitCrop interpolate the closure bridge?
FitCrop generates smooth intermediate geographic coordinates and continuous timestamps between your final and initial track points.
