Abstract

Spatial Data Infrastructures at national or higher levels usually comprise the access to multiple geographic data catalogs. However, with classical search systems, it is difficult to have a clear idea of the information contained in the metadata holdings of these catalogs. This paper describes a set of clustering techniques to create a thematic classification of geographic resource collections based on their associated metadata.
