Combining, Sharing and Constructing Geographical Knowledge Using “The Denshikokudo Web System”

Abstract

In this paper I examine about combining, sharing and constructing geographical knowledge on the Web with an E-learning system using land use maps developed by myself. A learner can represent geographical knowledge on a map as a legend data and a mesh map data on the system. By using this format, combination and reuse of mesh data, from personal level, to class level and then to inter-school level, are possible. Each mesh data is managed by the system. RDF and RDF schema are used for knowledge representation in metadata, mesh data and legend data. This system was implemented through a joint research with the Geographical Survey Institute, Government of Japan.
