摘要：NASA Earth Observing System (EOS) program is producing huge amounts of data that are vitally important for global human, economy and environment. However since these data are in HDF-EOS format, and can not be interoperated with and ingested by many GISs, thus it is highly desirable to make HDF-EOS data accessible to GIS users through Internet. GMU is pioneering the effort in developing OGC-compliant software, such as a software package NASA HDF-EOS Web GIS Software Suite (NWGISS), for making NASA EOS data available to general publics. This paper describes an important component of NWGISS, the Web Coverage Client (WCC). It enables the access of multi-dimensional and multi-temporal geospatial data from multiple coverage servers in the form that exactly matches users' requirements, regardless the original forms of the data in the servers. The easy-to-use and easy-to- install thick web client is the first web-based client in the world for GIS users to access the HDF-EOS data as well as other formatted data in an unified way, greatly enhancing the interoperability and public use of EOS data. Coupled with the NWGISS Server packages, WCC makes HDF-EOS data available to GIS users based on Open GIS Consortium's (OGC) interoperability protocols
