> Spectral Indices
> Simple tool that provides ability to compute 64 common spectral indices from EO/IR multi-band (MSI or HSI) raster datasets
> Exact number of indices that can be computed for a given input raster is based on its wavelength metadata
> Pléiades-1 = 27 | Landsat-8 = 35 | WorldView-3 = 44 | AVIRIS = 61
> Computation of spectral indices where band ratios using two or more bands are used to accentuate the spectral differences between materials
> Spectral indices provide a way to analyze materials in a manner that is not impacted by illumination or shadows and they have been used extensively in mineral exploration and vegetation mapping
> Ability to dynamically Preview the processing result before execution
> Implementation is multi-threaded with high performance processing
> Examples: NDVI, RDVI, LAI, EVI, SAVI, SR/RVI, BAI, WorldView-specific, etc.

> Helping you bridge the gap from Desktop application to Enterprise solutions
> Modern object-oriented programming interface for processing
> ENVITask encapsulates an atomic unit of processing work and provides a powerful level of introspection for users to learn about the task and all its parameters
> ENVITask supports both procedural and object oriented programming models
> Ability to automatically discover all of the tasks available for processing
> Parameter validation – Immediately checks property setting to ensure it is valid
> Parameter introspection – Programmatically access parameter name, brief description, required vs. optional, input vs. output, choice lists, default values, data type, min/max, current value
> Temporary file management – ENVITask's automatically generates & manages temporary output files (upon exit all temporary files are automatically deleted)
> Subsetting – Both spatial & spectral raster subsetting available via a modern object-oriented approach (i.e. no more DIMS & POS keywords)

> The following ENVI extensions were recently added/updated:
> ENVI Report Generator - The ENVI Report Generator extension allows you to create presentation-quality reports and report templates directly from ENVI5.
> Airbus Catalog Query - Allows users to search for SPOT & Pléiades imagery within then examine thumbnails & metadata to identify datasets to purchase from Airbus.
> Pyramid Creation Utility - This batch processing utility builds the .enp pyramid file used for raster dataset display in the ENVI5 software application.
> Generate Anaglyph - Create 3D anaglyphs using DEM and image data.
> ENVI5 en FRANCAIS - Catalogue pour une version Française de ENVI5.
> Program Generator - The ENVI Program Generator is a free ENVI plugin that allows users to create batch processes for ENVI5.
> Katalog - Organize your ENVI data library. Katalog is a free ENVI add-on that helps organize satellite images and other geospatial data.
> Running IDL code from ENVI - This utility will allow you to run IDL code from an ENVI-only (runtime) session.

> Fuze Go™ = commercial version of the patented UNB Pansharp algorithm for pan-sharpening EO/IR imagery (i.e. MSI + PAN image pairs)
> Fuze Go™ plugin for ENVI® is a Toolbox extension for a GUI dialog that facilitates execution of the Fuze Go™ software (sold separately) from ENVI5
> Fuze Go™ software must be purchased from Scene Sharp Technologies
> Plugin allows user to select input images, set processing parameters, specify an output file and optionally load the output image result back into ENVI5 application
> Plugin is supported in ENVI5 (no Classic) and only on Windows operating systems
> Benefits of Fuze Go™:
> Maintains signature accuracy and reflectivity values
> No data loss in the original multispectral image signature, which means the value of the image processing is additive to the analytics
> Process up to 30 multispectral bands advancing analytical capabilities from newer advanced multiband image data such as WorldView-3 with 16 bands
Extensions Library – Fuze Go™ plugin for ENVI®
NOTE: The Fuze Go™ plugin for ENVI® is not sold or supported by Exelis Inc.
