Use Odometry Data To Calculate Speed Where Available

Ken Taylor — Mar 22, 2012 07:20AM GMT

Speed from GPS is invariably not very accurate and it gets worse the shorter the interval between locations.

Therefore it would be great if you would accept odometry data and use this to calculate speed and possible distance when it is provided rather than calculating speed from GPS. Odometry data is generally available on bikes that can provide power and cadence data. There are people looking for services that can do this and at least one person is labelling speed as power so they can use existing services e.g. http://code.google.com/p/mytracks/issues/detail?id=523#c8
