Interactive cartographic route descriptions
Providing an adequate route description requires in-depth spatial knowledge of the route in question. In this article we demonstrate that despite having travelled a route recently and having much experience of the area in question, an individual may lack such a degree of knowledge. Previous research and experience informs us that a map is an effective tool for bridging gaps in one’s spatial kno...
متن کاملStories as Route Descriptions
While navigation instructions in terms of turn instructions and distances are suitable for guiding drivers on roads, a different context of use like pedestrian navigation requires extended routing data and algorithms as well as adapted presentation forms to be effective. In our work we study alternative forms of navigation instructions for pedestrians in city environments. In this paper we expl...
متن کاملCompressed Transmission of Route Descriptions
We present two methods to compress the description of a route in a road network, i.e., of a path in a directed graph. The first method represents a path by a sequence of via edges. The subpaths between the via edges have to be unique shortest paths. Instead of via edges also via nodes can be used, though this requires some simple preprocessing. The second method uses contraction hierarchies to ...
متن کاملGenerating More Natural Route Descriptions
In this paper we tackle the problem of generating natural route descriptions on the basis of input obtained from a commercially available wayfinding system. We adopt a standard pipelined natural language generation architecture, and focus in particular on the role of the generation subtasks of aggregation and referring expression generation in producing fluent output. Through examples we demons...
متن کاملActive legends for interactive cartographic animation
Active legends in cartographic animation serve the dual purpose of controlling the display of a map sequence and providing necessary information about the individual frames. Legends for cartographic animations have typically been implemented in a non-interactive form as individual legends that are synchronized with the display of the map. An active legend creates a tactual/visual association be...
