The Visualization andComputation System VCS version2.7, when it comes out, willsupport the HDF format for bothread and write operations. VCSgreatly facilitates the selection,manipulation, and display ofscientific data. By specifyingthe desired data set, the graphicsmethod, and the display template,the VCS user gains virtuallycomplete control over theappearance of the data display andassociated text. Although VCS isdesigned expressly to meet theneeds of climate scientists, thebreadth of its capabilities make it auseful tool for other scientificapplications.

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.

Conclusion

New HDF-EOS tools and utilities are needed to supportthe 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.

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.
