Exploring trajectory data using ComVis CMV tool VAST 2015 Mini-Challenge 1

In this paper we describe our analysis of VAST 2015 Mini-Challenge 1 data using a coordinated multiple views tool — ComVis [2]. We extend the ComVis data model [1] to support trajectories with events. We also improve user interaction and introduce a new view in order to support analysis. The data is processed so that it follows the new data model and fits in a single table. We answer some of the challenge questions and plan further research on data exploration and analysis based on the newly introduced data model, interaction, and views.
