Title: Gain Smoothing or Correction?
Post by: Fasterhorses on October 26, 2009, 01:49:37 PM

Hello Scott,

Are you going to put in some code (similar to what MotuionBased did) to smooth or correct the elevation fluctuations? I'm using my 705 on 1sec intervals because it makes a great track on these crooked horse trails I'm mapping but the raw gpx data shows 10-20 foot spikes in the elevations sometimes and with 1500 points in 3mi of trail the gain is way off and also screws up your nifty "difficulty & effort indexes".

I have some files you could look at but they are too big to attach here. 140-170KB. If you are interested give me a way to send them.

Great product tho and I'm going to buy the Pro version real soon.

TF does have various means of correcting for GPS elevation errors.  Check out the climbing analysis feature:

The only thing missing is an application of these methods to the climbing numbers in the main TF window (and by extension, to difficulty index and others).  That is definitely planned.

Thanks, glad the software is working out for you!
