VIIRS Software Tools

Note: You need to upgrade HDFViewer to version 2.7 to read VIIRS SDR files. The previous versions are not compatible (HDFViewer crashes). ENVI HDF5 plugin works only with simulated VIIRS SDR data. It appears that an upgrade on the ENVI HDF5 plugin is needed to become compatible with the real VIIRS SDR data.
