a QGIS-plugin for matching a trajectory with a network using a Hidden Markov Model and Viterbi algorithm

Because of inaccuracies of the GNSS signal and/or a low data quality of the network, the positions of the trajectory and the network are differing. In many cases a simple snapping of the trajectory on the network will not work to reproduce the real track on the network. Reasons for that can be e.g. outliers in the trajectory or crossings of edges in the network. This plugin provides a statistical approach to solve the problem of offline map matching using the principles of Hidden Markov Models (HMM) and the Viterbi algorithm.
