I see the same error (macOS El Capitan, HDFview 2.13) when I click on a Data object. Panoply gives "There was an error preparing the data: Unknown filter type=32000". See: https://support.hdfgroup.org/services/filters.html, where you will see: ----------------------------------------------------------------------------------------------------------------------------------------------------- LZF Filter *Filter ID:* 32000 *Filter Description:* The LZF filter is an alternative DEFLATE-style compressor for HDF5 datasets, using the free LZF library by Marc Alexander Lehmann. Its main benefit over the built-in HDF5 DEFLATE filter is speed; in memory-to-memory operation as part of the filter pipeline, it typically compresses 3x-5x faster than DEFLATE, and decompresses 2x faster, while maintaining 50% to 90% of the DEFLATE compression ratio. LZF can be used to compress any data type, and requires no compile-time or run-time configuration. HDF5 versions 1.6.5 through 1.8.3 are supported. The filter is written in C and can be included directly in C or C++ applications; it has no external dependencies. The license is 3-clause BSD (virtually unrestricted, including commercial applications). More information, downloads, and benchmarks, are available at the http://h5py.org/lzf/. *Additional Information:* The LZF filter was developed as part of the h5py project, which implements a general-purpose interface to HDF5 from Python. *Links:* The h5py homepage: http://h5py.org The LZF library homepage: http://home.schmorp.de/marc/liblzf.html *Contact Information:* Andrew Collette Web: http://h5py.org ------------------------------------------------------------------------------------------------------------------------------------------------------ Since ArcGIS uses python, you might be able to install the lzf filter where ArcGIS can use it.
