Abstract

In recent years there has been a considerable increase in the obtaining and availability of GNSS traces of communication pathways, contributed mainly by voluntary users. In this thesis we take advantage of these traces of low precision but very numerous to obtain a precise axis. For this we propose a method that identifies traces or outlier parts, generates a medium axis and performs a three-dimensional control based on a 3D buffer. The test has been based on an experiment design, which has included a large number of traces raised with different GNSS devices in a controlled area. The results obtained, in the form of medium axes, have been contrasted with the axis obtained with a precision GNSS survey. The results of positional accuracy have allowed us to obtain important conclusions about the proposed method and the devices used.
