Design of IHO S-100-compliant Application Schema for AtoN Data

Abstract

In the maritime field, e-navigation, an information-service framework for proper integration of various marine and marine-related data both shipboard and onshore, has been widely discussed. In the wake of the adoption of International Hydrographic Organization (IHO)’s S-100 as the baseline of the Common Maritime Data Structure (CMDS) for e-navigation, S100-based product specifications are being developed. The International Association of Lighthouse Authorities (IALA) is charged with the development of product specifications for its domain. In order to develop a data product specification, it is necessary to analyze the contents of the data and to define an application schema according to the S-100 data model. Aids to Navigation (AtoN) data in IALA domain constitute the typical resource of e-navigation. Thus, in this paper, we present an application schema for Aids to Navigation (AtoN) data. By analysis IALA Navguide and AtoN data provided by a regional marine office, we define an application schema on the basis of IHO S-100.
