VIIRS Imagery Environmental Data Records (EDRs) Software Version 2.0 Release
4 August 2014Update to the CSPP software package for transforming direct broadcast Suomi-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) Sensor Data Record (SDR) intermediate files into reprojected Imagery Environmental Data Record (EDR) products on Intel Linux computers. The Imagery EDR products are remapped into a Mercator projection relative to the satellite (Ground Track Mercator (GTM) projection). This reprojection removes the bow-tie effect and also maintains constant horizontal resolution in the cross-track and along-track directions. VIIRS Sensor Data Record (SDR) Binary Large OBject (BLOB) and matching .asc files are required input to the CSPP Imagery EDR software. These are intermediate files created as part of the CSPP SDR processing. By default, these files are deleted upon successful CSPP SDR completion; users must execute the CSPP SDR software using the "-e" option (viirs_sdr.sh -e) in order for the intermediate files to be retained. What's new in Version 2.0?
The CSPP VIIRS EDR algorithms are designed to work with CSPP VIIRS SDR version 2.0.
