Though if you're somewhere very hilly (ahem Pittsburgh) it appears that slight issues with the GPS track will throw in a lot of extraneous elevation data.
- cullenking 17y agoWe are working on some cool ways to fix GPS tracks that have drop-outs in signal/accuracy. I am going to use some signal processing tricks to smoothout the points along the route. I am using a Gaussian filter on the elevation data, and I think this will also work good on the actual lat/lng points, which should also help with total gain/loss accuracy.
