New Features
ENVI 5.2, Service Pack 1 includes the new and enhanced features listed below. See the following sections:
Sensors and Data Formats
ENVI reads and displays imagery from the following sensors and data formats:
- ALOS-2 PALSAR
- SPOT 7 DIMAP
- VNREDSat-1
The ENVI Orthorectification Module supports the following sensors: AlSat-2A, Gaofen-1, GeoEye-1 in DigitalGlobe format, Landsat-8, Pleiades-1A, SPOT-6/7 DIMAP, VNREDSat-1, WorldView-3, Ziyuan-1-02C, and Ziyuan-3A.
Image Processing
Use the Radar Backscatter tool to calibrate a radar amplitude raster to sigma nought backscatter, in decibels. It currently only works with ALOS-1 or ALOS-2 PALSAR Level-1.5, 2.5, and 3.1 data.
Esri® Integration
ArcGIS Image Services that require an ArcGIS portal account or ArcGIS online account are now supported. Image Service catalog items are also supported.
User Interface
Real-time Ortho is a new feature for digitized vector and ROI layers. In previous versions of ENVI, any digitized vector or ROI layer that was created on top of an image containing RPC coefficients produced only pixel-based, unprojected geometry. While you could use these vector and ROI layers with the RPC image, they did not contain projection information that allowed them to relate to other images. Also, if you displayed a projected layer in the same view as an unprojected RPC image, the RPC image reprojected into the newly established base projection. Now, with Real-time Ortho, vector and ROI layers created on top of an RPC image will contain projected coordinates that can display with other projected imagery, and projected vector and ROI layers will display on top of an existing RPC image without reprojecting the RPC image.
The following are also supported with Real-time Ortho:
- Vector and Raster Color Slices created on top of an image with RPC coefficients will produce projected .shp output.
- ROIs created on top of an image with RPC coefficients will produce projected .xml output.
- RPC images can be processed directly with any of ENVI's workflows, such as Segment Only Feature Extraction, and produce projected .shp output without the need to orthorectify the image first.
- Go To will work with the projected coordinates.
If you display two RPC images in the same view, ENVI will automatically reproject the imagery to a geographic Lat/Lon WGS-84 coordinate system to allow ENVI to work in GCS_WGS_1984 mode. Geographic reprojection is the default setting for the new Base Projection for the Non-Standard Rasters preference; you can change the default to UTM, if desired.
Programming
You can create custom data-processing tasks using IDL and ENVI application programming interface (API) code. If you also use the ENVI Services Engine (ESE), the custom tasks will be available in the ESE Admin Console so that you can process data as a web service.
The ENVI::OpenRaster method reads spectral library files (*.sli) as rasters.

Known Issues
| ENVI-70387 |
InstallShield Wizard graphics may not appear on Windows 7 multi-byte systems |

| ENVI-70066 |
Opening two FG-1 WFV images results in image artifacts |
| Opening two Gaofen-1 images in the same view results in gaps of data. Workaround: Display multiple Gaofen-1 images in separate views. |
| ENVI-70110 |
Georeferencing from GLT produces holes in a south polar stereographic projection |
| When using Latitude/Longitude bands to create a geographic lookup table (GLT), images geogreferenced using the GLT in a southern hemisphere polar stereographic projection contain holes near their center. |
| ENVI-70139 |
Vector layer is hidden temporarily on "Accept" while animating a raster series |
| If you draw a polygon vector layer and accept it while a raster series is animating, the polygon layer disappears. Workaround: Pause the animation between Accept operations, or step through the series one frame at a time while editing the vector layer. |
| |
Installation error on Windows platforms: "Key not valid for use in specified state" |
| Some customers have reported this error during the installation process. It is caused by a Microsoft update (KB2918614), which affects the Windows installer service. Workaorund: uninstall this Microsoft update. For more information, see the Microsoft Community website. |
