Abstract

Nowadays, geographic data, such as NASA's Earth Observation System (EOS) data, are playing an increasing role in many areas, including academic research, government decisions and even in people's every lives. As the quantity of geographic data becomes increasingly large, a major problem is how to fully make use of such data in a distributed, heterogeneous network environment. In order for a user to effectively discover and retrieve the specific information that is useful, the geographic metadata should be described and managed properly. Fortunately, the emergence of XML and Web Services technologies greatly promotes information distribution across the Internet. The research effort discussed in this paper presents a method and its implementation for transforming Hierarchical Data Format (HDF)-EOS metadata from the NASA ECS model to ISO 19115-based XML, which will be managed by the Open Geospatial Consortium (OGC) Catalogue Services-Web Profile (CSW). Using XML and international standards rather than domain-specific models to describe the metadata of those HDF-EOS data, and further using CSW to manage the metadata, can allow metadata information to be searched and interchanged more widely and easily, thus promoting the sharing of HDF-EOS data.

Funding

This project was supported by grants from the NASA Earth Science Data and Information System Project (NCC5-645, PI: Dr. Liping Di), NASA Advanced Information System Technology program (NAG-13409, PI: Dr. Liping Di), and NASA REASoN program (NNG04GE61A, PI: Dr. Liping Di). Additional funding was provided by the Open Geospatial Consortium (OGC) for the development of Web Coverage Server, Web Map Server and Catalog Service for the Web as a part of OGC Web Mapping Testbed II (WMT II) and OGC Web Services Phase 2 (OWS-II). We sincerely thank our colleague, Dr. Barry Schlesinger, for proofreading the manuscript.
