Utility to converts EOSDIS data from HDF-EOS2 to GeoTIFF formats.

• Versions Available:– Stand-alone: A downloadable desktop version – Data Pool: Access through NASA archive online

storage

HEGHEG

HEG FunctionalityHEG Functionality

• Conversion:

–HDF-EOS (Swath or Grid ) to a single-band or multi-band GeoTIFF’s

–HDF-EOS Swath to HDF-EOS Grid or Swath

–HDF-EOS Swath or Grid to generic Binary (with metadata file)

• Subsetting (spatial, field, band)


• Stitching (mosaicing) + subsetting + Reprojecting

• Reprojection ( to UTM, PS, TM, STP, LCC, LAMAZ,

GEO, SIN, Albers, CEA)

• Subsampling (Subsample stacks)

• Running from Command Line (batch jobs)

or with Java-based GUI


• Metadata preservation/creation.

• Currently supports

MODIS, MISR, ASTER, AIRS, AMSR-E products on TERRA and AQUA (>115 products),

• Operable on Sun, SGI, Win, Linux, MAC


• Integrated into ECS Data Pool–Reduces the transfer time of HDF-EOS data sets

(if subset is requested)

–Provides the end-user with the exact file required by their application

• User Interface–Portable, written in Java.

–Not dependent on COTS (eg. IDL).

HDFView Plug-inHDFView Plug-in

• HDFViewA Java-based browser from THG for

HDF4 and HDF5 based data.

• HDF-EOS plug-in

– Extends HDFView to browse HDF-EOS data in both versions (2 & 5).

– Is a plug-in module does not change THG HDFView functionality

– identical look and feel when displaying HDF and HDF-EOS objects

– access to complete breakdown of HDF-EOS objects. e.g. grid info, projection info, dims, datafields, and attributes
