SketchMapia: a Framework for Qualitative Alignment of Sketch Maps and Metric Maps (got 2nd best poster award)

Zusammenfassung

Sketch maps are externalization of the individuals' mental image of the environment. Being aware of the typical cognitive impact in cognitive maps, we developed a qualitative alignment framework called SketchMapia, which establishes an alignment between a sketched configuration and the corresponding configuration in the real world represented on a metric map. As typically only qualitative relations are persevered in sketch maps, SketchMapia processes spatial information on a qualitative level [1-3]. The project aims at relaxing technical constraints to create,assemble, and disseminated spatial information from freehand sketches provided by layperson. The system interprets input sketches, computes qualitative descriptions in the form of Qualitative Constraints Networks (QCNs), and determines potential alignments between sketch and corresponding metric maps based on the consistent qualitative descriptions. The successful alignment of spatial objects helps to integrate information from sketch and metric maps into one data repository. An intuitive web-interface makes the system accessible
