Analysing tourism movements along the Danube river based on geotagged Flickr photography

Abstract

Abstract. The Danube, connecting ten countries with large cities, national parks and other smaller destinations is a branded as integrated destination system of Europe. This paper examines the behaviour of visitors along the river by analysing the spatio-temporal distribution of geotagged photos shared on Flickr. The authors downloaded the metadata of more than 2 million geotagged photos along the river, and created a weighed movement graph based on the short time-interval user movements. The network analysis of the graph revealed the central integrating effect of the large capital cities on the entire system. Modularity analysis indicated 18 regional tourism clusters, which are connected into three major separated destination systems which have little relation between them and the isolated clusters of Lower Danube.This paper discusses the method of data aggregation as well as the tools used and created for visualising and analysing the data.
