Linking VGI for place-based map generalization


Bahrehdar, Azam; Purves, Ross S (2016). Linking VGI for place-based map generalization. In: AGILE 2016, Helsinki, 14 June 2016 - 14 June 2016, 1-4.

Abstract

Traditional map production is a top-down process driven by national mapping agencies. We argue that VGI have the potential to allow us to create place-based maps, and in particular that VGI in the form of Flickr data can be used to drive generalization operators applied to Open Street Map data. We introduce a method to link the descriptions associated with georeferenced Flickr images to Open Street Map geometries for popular London locations, and demonstrate that rich semantic data, contributed by many users, are available after filtering for bias. We illustrate the potential application of our approach to three generalization operators.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
