Abstract

The bridging of accumulated Earth Observation and Model Simulation Earth science information and urgent needs of the information in different communities and applications poses a global challenge in the 21st century. The Earth Science Information Partnership (ESIP) proposes to develop an Earth Information Exchange (EIE) in testing relevant technology mechanisms to provide a solution/platform for addressing the challenge. Through the development in the past years of infusing different new technologies to support the platform, a near operational EIE is ready. The EIE provides widely needed functions through new technologies in 1) accessing multiple catalogs, such as GCMD and ECHO, from the same entry point; 2) supporting interoperable interfaces, such as OGC WMS/WFS/WCS and CS-W, and community standards, such as OpenDAP and HDF-EOS; 3) providing multi- dimensional data selection and visualization with NASA World Wind and Google Earth; 4) providing knowledge based information search with Earth Science ontologies; and 5) searching and discovering catalogs progressively. Technologies gradually integrated into the EIE includes 1) generic IT technologies, such as JSR168/268 and Ajax; 2) interoperable interfaces, such as OGC specifications and ISO/TC211 and FGDC standards; 3) multiple catalogs, such as GOS and NCDC; 4) Service Oriented Architecture (SOA), such as geoscience interoperability; 5) semantic and ontology for knowledge reasoning, such as SWEET and NOESIS; 6) 3D and 4D visualization techniques, such as that provided by World Wind and Google Earth; 7) and many others. This paper will introduce the strategies we took in integrating those technologies to support the functionalities of information and knowledge sharing for different communities and applications.
