NCSA Tools Tool Description The NCSA Java-based HDF Viewer (JHV): It is a Java-based implementation of an HDF Viewer. The NCSA Collaborative Java-based HDF Viewer: It is a version of JHV which allows several users to simultaneously browse the contents of an HDF file across a local area network or the internet.

EOSDIS Project Tools Data and Information Access Link ( DIAL) is a package of software tools based on WWW to provide access to data. It has many features such as browsing, plotting, subsampling and subsetting. Currently it works with HDF files in UNIX environment. This package will work with HDF-EOS files in future. EOSView is a HDF browser developed by the ECS project to display HDF data. This tool is under development and eventually will become HDF-EOS browser. 6 HDF Vendors/Software Developers Workshop

Summary • NASA does not endorse any particular tool discussed in this presentation • Little additional tools development has occurred in the last two years for browsing and displaying HDF formatted data. • Very few tools are available to support HDF-EOS formatted data. 37 HDF Vendors/Software Developers Workshop

Conclusion New HDF-EOS tools and utilities are needed to support the terabytes of EOS AM-1 data from multiple instruments and disciplines. Types of tools HDF-EOS data ingest capability for the existing image processing and analysis packages New image processing packages with additional functionality for analysing and integrating Earth Science data. 38 HDF Vendors/Software Developers Workshop

Types of tools • Browsers • Data dumpers • Translation tools Tools and utilities developed to work with HDF-EOS data as well as HDF will attract the broader community of HDF users. 39 HDF Vendors/Software Developers Workshop
