ENVI Release of 1312/12/14 5:40 PMSensors and Data FormatsENVI reads and displays imagery from the following sensors and data formats:AlSat-2A1. Deimos-12. Gaofen-13. GRIB-1 and GRIB-24. Multi-page TIFF5. NetCDF-46. Proba-V S10 TOC products, including NDVI7. Proba-V S1 TOA and TOC products8. SkySat-1 Image Frames9. WorldView-310. Ziyuan-1-02C and -3A11. ENVI plays videos files, including those from Skybox Imaging. The Full Motion Video playerdisplays MISB metadata if the video file contains it. Export individual frames to the ENVI displayfor further analysis, or convert a video file to a time-enabled raster series. ENVI reads thefollowing video formats in the Full Motion Video player:Adobe Flash Video (.)

Skybox (SkySat) video files15. Image ProcessingSpatiotemporal AnalysisYou can build a series of images (also called a raster series) for spatiotemporal analysis, whichprovides the ability to understand and predict Earth surface processes or human activities overspace and time.

4 ENVI automatically reads raster "acquisition time" metadata from a wide varietyof sensor data sources. Use the following tools:Build Raster Series: create a series file that references the file locations of images inyour collection. You can order the raster series sequentially according to acquisitiontime Reproject Raster Series: Normalize a stack of rasters to a common spatial grid withautomatic resampling and Series/Animation Manager: View and animate a spatiotemporal series with time sliderand wheel controls. Also export a raster series to common video Write IDL scripts to perform all of these tasks; see the Programming section Learn how to build and animate a series of Landsat images in the Time Series Spectral IndicesUse the Spectral Indices tool to compute various indices (one at a time), including vegetation,geology, man-made features, burned areas, and water.

5 It includes all of the existing vegetationindices from the Vegetation Index following are new vegetation indices:Difference Vegetation Index1. Global Environmental Monitoring Index2. Green Atmospherically Resistant Index3. Green Difference Vegetation Index4. Green Normalized Difference Vegetation Index5. Green Ratio Vegetation Index6. Green Vegetation Index7. Infrared Percentage Vegetation Index8. Leaf Area Index9. ENVI Release of 1312/12/14 5:40 PMModified Chlorophyll Absorption Ratio Index10. Modified Chlorophyll Absorption Ratio Index - Improved11. Modified Non-Linear Index12. Modified Simple Ratio13. Modified Triangular Vegetation Index14. Modified Triangular Vegetation Index - Improved15. Non-Linear Index16. Normalized Difference Water Index17. Normalized Multi-band Drought Index18. Optimized Soil Adjusted Vegetation Index19.

Transformed Difference Vegetation Index25. Triangular Vegetation Index26. Visible Atmospherically Resistant Index27. WorldView Improved Vegetative Index (WV-VI)28. The following are new indices for other features: burn Area Index1. Clay Minerals Ratio2. Ferrous Minerals Ratio3. Iron Oxide Ratio4. Normalized burn Ratio5. Normalized burn Ratio Thermal 16. Normalized Difference Built-Up Index7. Normalized Difference Snow Index8. WorldView Built-Up Index9. ENVI Release of 1312/12/14 5:40 PMWorldView New Iron Index10. WorldView Non-Homogenous Feature Difference11. WorldView Soil Index12. Use the ENVIQ uerySpectralIndices API routine to determine which indices can be computed for agiven IDL scripts to compute spectral indices.

7 See the Programming section EO-1 Hyperion Vegetation Indices tutorial shows how to pre-process Hyperion data and usevegetation indices to examine areas of unhealthy vegetation in a burn Indices tutorial shows how to create and compare spectral indices of burned areas fromLandsat-8 New Image Processing FeaturesThe NNDiffuse Pan Sharpening tool uses the nearest neighbor diffusion (NNDiffuse) pansharpening algorithm to create a pan-sharpened raster from a low-resolution multispectralraster and a high-resolution panchromatic hyperspectral analysis tutorial explains how to use Spectral Angle Mapper (SAM) classificationand Spectral Feature Fitting (SFF) to compare image spectra to reference Scatter Plot tool has been updated for the new ENVI interface. Select bands from differentrasters, create density slices, import/export ROIs, create a spectral profile, calculate meanspectra and class statistics, export plots to common formats, etc.

8 The "dancing layers"functionality highlights pixels that correspond to the cursor location in the Image Raster Color Slice tool performance has improved; the histogram plots have tick marks andlabels, the ability to zoom in/out, and a cursor crosshair that reports pixel Feature Counting tool has been redesigned:Features are listed in a table view that provides colored text and the ability to Symbols, labels, and counts can be turned on and off in the New symbols have been Geolocation parameters are automatically determined for features derived from ageoreferenced Features contain an optional Description field for capturing additional A Grid option allows you to overlay grids on the top-most layer listed in the Save features to an ENVI Feature Counting file (.efc) and restore this type of file in a7.
