This document describes three tools for working with HDF-EOS data files: hdfeos4to5, H5EOSView, and the Java EOS Browser (JEB). Hdfeos4to5 converts HDF-EOS objects between HDF4 and HDF5 formats. H5EOSView displays HDF5 HDF-EOS objects with an interface identical to EOSView. JEB is a Java interface that displays HDF-EOS objects from HDF4 and HDF5 files and allows viewing field data and attributes.
