摘要：Digital map systems are used daily in order to organize and search information before a travel and to display and examine a travel record. In our previous study, we proposed the focus+glue+context map system EMMA (Elastic Mobile MAp) which provides both local detailed data and global context data in the same view, providing uniform scaling of focus and context areas by placing a glue area between the two areas. This paper presents a Web-based travel route editor on EMMA, which allows users to enlarge the areas around the waypoints and route tracks while watching the whole route. The proposed system includes the following features. (1) An intuitive interaction with the displayed objects (route tracks, landmarks) and the focus function enhance the examination and understanding. (2) The system simulates all the travel by placing a focus area at the start that automatically follows the route tracks displaying the area in detail. When a track is reached, additional information such as pictures and descriptions attached to the route is automatically displayed. (3) The system allows users to design and draw travel routes by selecting vector map data from a database. GPS data can be loaded from files and displayed as a reference. Most of the user interaction in the route drawing process is effectively reduced by implementing the following path algorithm to suggest a path. (4) There may be places without vector map data such as parks and mountains. The user is able to create intuitively new roads. This paper shows the implementation methods and a prototype of the proposed system which we developed on EMMA
