Distance calculations

Beitrag von Miha Majetič »

Hi! I have a question regarding distance calculation in TrackGuru. How TrackGuru calculate distance from start to specific point in gpx (which model is using etc.)? In your experience, how accurate are this distances (let's say for 100 km long path)? Thank you for all answers.

TG uses a 3D Pythagoras' theorem between each point, so it takes elevation difference into account (even if that effect is very small).

The accuracy depends a little on the number of track points and mostly on the amount of errors/noise from the GPS signal in the track.
