Automated tabular itinerary visualization
Marco Adelfio, Hanan Samet · 2014
Advances in geographic information extraction have exposed previously untapped resources, such as many travel itineraries found in HTML tables and spreadsheets on the Web. In the general sense, itineraries differ from the related concepts of routes and trajectories in that the precise paths between stopping points are of far less importance than the locations of the stopping points and their order. This characteristic allows for some flexibility when visualizing itineraries. A method for automatically generating itinerary visualizations is presented, which utilizes principles from graph-drawing and map labeling, along with additional criteria designed specifically for the itinerary visualization task. We describe a system based on this method that can perform automated layout for arbitrary itineraries at varying scales.
