This data is an example taken from the DIAL system. DIAL is a WWW based data distribution system. It allows data providers to easily serve their Earth science data directly to their users. DIAL provides traditional catalog services like metadata search, while also providing extended interactive data services like browsing, subsetting, subsampling, reformatting and direct downloading. The power of DIAL has recently been enhanced by the addition of the EOSDIS "Version 0" protocol, which enables a project to set up a distributed system of DIAL servers. DIAL supports Hierarchical Data Format (HDF) and HDF for EOS (HDF-EOS) formatted datasets. DIAL also provides interoperability with GIS systems through traslators.
