What’s New in ENVI 5.3

As the geospatial industry continues to evolve, so too does the software. Here’s a look at what’s new in ENVI 5.3, the latest release of the popular image analysis software from Exelis VIS.

ENVI

  • New data formats and sensors. ENVI 5.3 now provides support to read and display imagery from Deimos-2, DubaiSat-2, Pleiades-HR and Spot mosaic tiles, GeoPackage vectors, Google-formatted SkySat-2, and Sentinel-2.
  • Spectral indices. In addition to the numerous indices already included in ENVI (more than 60), new options include the Normalized Difference Mud Index (NDMI) and Modified Normalized Difference Water Index (MNDWI).
  • Atmospheric correction. The Quick Atmospheric Correction (QUAC) algorithm has been updated with the latest enhancements from Spectral Sciences, Inc. to help improve algorithm accuracy.
  • Digital elevation model. Users can now download the GMTED2010 DEM (7.5 arc seconds resolution) from the Exelis VIS website for use in improving the accuracy of Image Registration using RPC Orthorectification and Auto Tie Point Generation.
  • Point clouds. If you subscribe to the ENVI Photogrammetry Module (separate license from ENVI), then the Generate Point Clouds by Dense Image Matching tool is now available for generating 3D point clouds from GeoEye-1, IKONOS, Pleiades-1A, QuickBird, Spot-6, WorldView-1,-2 and -3, and the Digital Point Positioning Data Base (DPPDB).
  • LiDAR. The ENVI LiDAR module has been merged with ENVI and can now be launched directly from within the ENVI interface.
  • Geospatial PDF. Your views, including all currently displayed imagery, layers and annotations in those views, can now be exported directly to geospatial PDF files.
  • Spatial subset. When selecting files to add to the workspace, the File Selection tool now includes options to subset files by raster, vector, region of interest or map coordinates.
  • Regrid raster. Users can now regrid raster files to custom defined grids (geographic projection, pixel size, spatial extent and/or number of rows and columns).
  • Programming. The latest ENVI release also includes dozens of new tasks, too numerous to list here, that can be utilized for developing custom user applications in ENVI and ENVI Services Engine.
