Abstract: The widespread availability of hand-held GPS units has led to a proliferation in data on the tracks of individuals as they walk, drive or otherwise go about journeys. This data has been used in a number of ways - for example the OpenStreetMap project (The OpenStreetMap Foundation 2007). One characteristic of projects such as this is that there will often be several GPS tracks for the same stretch of road. In general, repeatedly measuring something and taking the average of measurements leads to a more accurate result. The question addressed here is “is it possible to ’average’ GPS tracks and if so, does this lead to a better estimate of road location?”.
