theclaretvillan Posted March 4, 2010 Share Posted March 4, 2010 I know this has probably been discussed many times before and tried a search but.... Does the trip odometer distance on my Oregon give just the horizontal distance covered or a combination of Horizontal and vertical distances i.e. closer to the accutate distance travelled... Thanks in advance. Quote Link to comment
+StarBrand Posted March 4, 2010 Share Posted March 4, 2010 Unless you are traversing up and down lots of remarkably steep slopes over a large distance, the distance travelled over a smooth earth is very close to what you actually did most times. Having said that - I do not believe that the Oregon is including vertical travel. Quote Link to comment

Even on a recent hike I did of around 20km with over 1250m of climb it only made about 0.2km difference, about 1% at most, so don't sweat it. Quote Link to comment

But is it as I thought that the Oregon gives the horizontal distance? Quote Link to comment
+Red90 Posted March 4, 2010 Share Posted March 4, 2010 The distance shown is horizontal only. Vertical is shown as altitude change. Actual distance can be calculated. It can be a large difference around here... One hike I recall being 800 m vertical in 1500 m horizontal. Quote Link to comment

It can be a large difference around here... One hike I recall being 800 m vertical in 1500 m horizontal. 1,500 m horizontal / 800 m vertical is a pretty rugged hike (almost rock climbing!). Pythagoras' Theorem gives 1,700 m slope length, or a 13% error, compared to the 1,500 m horizontal measurement. Errors due to slope effect for more common "walking" gradients are much smaller - 1% or so. Quote Link to comment
