A Look at What’s New in ENVI 5.1

ENVI 5.1(16-Dec-2013) Today Exelis Visual Information Solutions released ENVI 5.1, the latest version of their popular geospatial analysis software.

We’ve already downloaded and installed our copy, so read below if you want to be one of the first to learn about the new features. Or better yet, if you or your organization are current with the ENVI maintenance program, you too can download the new version and start using it yourself today.

Below are a few highlights of the new features in ENVI 5.1:

  • Region of Interest (ROI) Tool. Previously only accessible in ENVI Classic, users can now define and manage ROIs in the new interface. This includes the ability to manually draw ROIs, generate ROIs from band thresholds, grow existing ROIs, and create multi-part ROIs. Additionally, ROIs are now stored as georeferenced features, which means they can be easily ported between images.
  • Seamless Mosaic Workflow. The Georeferenced Mosaicking tool has been replaced with the new Seamless Mosaic Workflow. This tool allows user to create high quality seamless mosaics by combing multiple georeferenced scenes. Included is the ability to create and edit seamlines, perform edge feathering and color correction, and export finished mosaics to ENVI or TIFF formats.  Also included are tutorials and tutorial data to learn the simple and advanced features of this workflow.
  • Spectral Data. Both the Spectral Profile and Spectral Library viewers include improvements for visualizing and analyzing spectral data. The software also includes updated versions of four key spectral libraries: ASTER Spectral Library Version 2, U.S. Geological Survey Digital Spectral Library 06, Johns Hopkins University Spectral Library, and the NASA Jet Propulsion Laboratory Spectral Library.
  • Additional Data Types. ENVI 5.1 can now open generic HDF5 files, which includes data distributed from sensors like NPP VIIRS, SSOT, ResourceSat-2, and HICO. Additional data types and file formats also now supported include ECRG, GeoEye-1 in DigitalGlobe format, Goktuk-2, KOMPSAT-3, NigeriaSat-1 and -2, RASAT, and others.
  • Added Landsat 8 Support. Various improvements have been included for the handling of Landsat 8 data, such as automatically reading the thermal infrared coefficients from the associated metadata, including the Quality and Cirrus Cloud bands in the Data and Layer Managers, correcting reflectance gains and offsets for solar elevation, and updating FLAASH to process Landsat 8 imagery.

These and other welcome improvements continue to expand the capabilities of ENVI, and we’re excited to start working with the new features.
