A Visualisation of a Hierarchical Structure in Geographical Metadata

• The paper presents a visualisation of a hierarchical structure discovered in a repository of geographical metadata by clustering. The hierarchical structure is visualised as a radial tree. The clusters at different levels of detail are represented by the vertices and the subset relationship between the clusters by the edges of the tree. The similarity between elements in different clusters is shown using a colour scheme for the vertices and the edges. The visualisation is integrated in a visual data mining tool for the exploration of the geographical metadata.
