The HDF-EOS To GeoTIFF Conversion Tool (HEG) is a tool developed to allow a user to reformat, re-project and perform stitching/mosaicing and subsetting operations on HDF-EOS objects. It can also reformats and re-project some SMAP, VIIRS and SRTM products. The output GeoTIFF file is ingestible into commonly used GIS applications. HEG will also write to HDF-EOS Grid & SWATH formats (i.e for Subsetting purposes) and native (or raw) binary. HEG presently works with MODIS (AQUA and TERRA), ASTER, MISR, AIRS, and AMSR-E HDF-EOS data sets.It also handles OMI HDF-EOS5 grid, SMAP L3/L4 HDF5 data sets, VIIRS L2/L3 netCDF/HDF-EOS5 products staged at the DAACs, and some SRTM binary products at LPDAAC.
Brief Summary of Features include:
- Reprojection
- Spatial (geolocation) Subsetting
- Band and Parameter (aka Field) Subsetting of HDF-EOS datasets
- Support for MODIS, ASTER, MISR, AIRS, AMSR-E, SRTM, VIIRS, and SMAP(and some OMI, MOPITT, etc)
(Check List of Supported Products for full details) - Format Conversion of various output Format types: GeoTIFF, HDF-EOS GRID & SWATH, MultiBand GeoTIFF, Multi-Band HDF-EOS GRID & SWATH, and native binary.
- Format Conversions without reprojection or manipulation of input data. Allows data to remain in original unaltered state.
- Stitching (or mosaicing) HDF-EOS SWATH and GRID datasets
- Stitching with combinations of Reformatting/Reprojection/Subsetting Operations
- Data subsampling
- Control of various parameters including output pixel resolution and output projection parameters
- Metadata preservation and creation
- Java GUI
- Command-line interface (Useful for running batch jobs. This is usually seen in automated production environments where large quantities of granules are processed.)
- Supported Platforms: LINUX, WINDOWS, SUN(old versions of HEG), and MAC OSX (built on Darwin Kernel Version 16.7.0)
Please note that binaries for 2.12 and older have been removed from our download site.
