In this directory you will find both the plain HDF4 handler RPM along with two other versions compiled using options that enable special features for use only with HDF-EOS files. One of the RPM packages is a copy of the handler with special code to process HDF-EOS, while the other combines that functionality with special code to support COARDS (aka 'short names). Below is the README from the source distribution which contains some more information on how the different versions were built and features provided by the options. To use the HDF-EOS versions of the handler, you must also install the HDF-EOS library, available from NASA. = Original README File = In this release, we greatly enhance the support of the access of NASA HDF-EOS2 and HDF4 products. To take advantage of this feature, one MUST use HDF-EOS2 library and configure as follows: ./configure --with-hdf4= \ --with-hdfeos2= \ --prefix= Since some HDF4 variable paths are pretty long. To follow COARDS conventions, one can configure as follows: ./configure --with-hdf4= \ --with-hdfeos2= \ --prefix= --enable-short-name The following NASA HDF-EOS2 products are tested with IDV and Panoply, check the Limitation section for the limitations: 1). NASA GES DISC AIRS/MERRA/TOMS 2). NASA LAADS/LP DAAC/NSIDC Many MODIS products 3). NASA NSIDC AMSR_E/NISE products 4). NASA LaRC MISR/MOPITT/CERES-TRMM The following NASA special HDF4 products are tested with IDV Panoply, check the Limitation section for the limitations: 1). NASA GES DISC TRMM Level 1B, Level 2B Swath TRMM Level 3 Grid 42B and 43B 2). OBPG(Ocean Color) SeaWiFS/MODIST/MODISA/CZCS/OCTS level 2 and level 3m(l3m) 3). Some LaRC CERES products CER_AVG_Aqua-FM3-MODIS,CER_AVG_Terra-FM1-MODIS CER_ES4_Aqua-FM3_Edition1-CV or similar ones CER_ISCCP-D2like-Day_Aqua-FM3-MODIS or similar ones CER_ISCCP-D2like-GEO_ or similar ones CER_SRBAVG3_Aqua or similar ones CER_SYN_Aqua or similar ones CER_ZAVG or similar ones There are some limitations in the current HDF-EOS2 module. For the details of limitations and others, please read README under the directory of the HDF4 handler code. To take advange of the above features with RPMS, one MUST use the RPMS built with EOS options.
