Wonder if this would be accurate enough for a GPS -> bike route translator. Like say you want to see the altitude throughout your bike right from the gps you recorded.
- akgerber 17y agoThe RideWithGPS people appear to do this: http://ridewithgps.com/trips/22776 http://ridewithgps.com/trips/22776 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.
- cullenking 17y agoWould be decently accurate, though their approximations would lead to a misrepresentation of gain/loss. However, their daily limits would really inhibit use of this service for said purpose, since my Garmin bike computer records easily 2000 points in a 30 mile ride, even on smart recording (every few seconds)
