HDF-EOS to GeoTIFF Conversion Tool & HDF-EOS Plug-in for HDFView Abe Taaheri, Raytheon IIS HDF & HDF-EOS Workshop XIV Champaign, IL Sep. 29, 2010
Utility to convert EOSDIS data from HDF-EOS2 to GeoTIFF formats. Versions Available: Stand-alone: A downloadable desktop version Data Pool: Access through NASA archive online storage HEG
HEG Functionality Conversion: HDF-EOS (Swath or Grid ) to a single-band or multi-band GeoTIFF’s HDF-EOS Swath toHDF-EOS GridorSwath HDF-EOS Swath or Grid to generic Binary (with metadata file) Subsetting (spatial, field, band)
HEG Functionality 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
HEG Functionality Metadata preservation/creation. Currently supports MODIS, MISR, ASTER, AIRS, AMSR-E products on TERRA and AQUA more than 115 products Operable on Sun, SGI, Win, Linux, MAC
HEG Functionality 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).
Examples (MISR) Mt. Etna Eruption: MISR L1B Stitched Blocks
Examples (MODIS) 2004 Hurricane Francis, MODIS MOD021KM, Multi-Band GeoTIFF, 3 bands: EV_1KM_RefSB, Bands 1,2,5
Examples (ASTER) AST_L1B, 2003 California Fires Geo. projection, Multi-Band GeoTIFF (3 bands): Visible Near Infrared (VNIR) ….. and Subsetted Two Swaths Stitched …..
HDFView Plug-in HDFView AJava-based browserfrom The HDF Group 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 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
HDFView Plug-in Some features in the Plug-in
Swath, Grid, and Point Objects Plug-in file treeview Swath/Grid Lat/Lon display
AMSR-E Swath One click to convert HE2 to HE5 file format
AMSR-E Swath Getting Image of selected pixels in a table Getting lat/lon for a selected pixel in a table
AMSR-E and OMI Point objects Different icons for different hdf-eos objects HE2 Point Object HE5 Point Object
