Taggram: Exploring Geo-data on Maps through a Tag Cloud-Based Visualization
Searching and exploring on digital maps are normally performed through simple text boxes and zoomand-pan interfaces. In this paper, however, we present a novel technique, namely Taggram, which combines texts onto maps to support geo-tagged data exploration. It is designed to show geo-tagged data in form of size-varied and colorized tags, benefiting by the concepts of Tag Clouds, and to support exploring those data interactively through a fisheye menu adaptation. The technique was demonstrated for geo-tagged data exploration; however, as other thematic geo-data can be partially represented in form of texts, Taggram can be a method for the presentation and exploration of such geo-data in other application scenarios. Keywords--- Text Visualization, Tag Clouds, GeoTagging, Map Labeling, Cartography.
