Abstract

This paper presents a system for making a pictorial and verbal representation of a travel trace from a GPS trace with the following functions: (1) A function to make a travel trace consisting of following paths and off-road paths, which indicate the turns and the reached districts. (2) A function that generates a partonomic tree that contains the sections of the travel trace, i.e. portions of the paths of the travel trace associated with verbal information, such as toponyms, route names, and district names. (3) A function that generates clickable labels that represent the sections of a travel trace in a map view. By using the labels, users can obtain detailed information while using a small map scale, understand the part-of relations among the administrative regions represented, and intuitively navigate the representation based on the verbalized sections. We have developed a prototype of the proposed system for a web-based interactive map service, which receives either a KML or a GPX file with a GPS trace, and provides a pictorial and verbal travel trace representation on a focus+glue+context map developed in our previous work. Using the prototype, we have confirmed the feasibility of the proposed system.
