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

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.

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
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.

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.
