What’s New in SARscape® 5.4

The newest release of SARscape – version 5.4.0 – introduces several algorithmic improvements and new features. The key features among the new enhancements are:

  • New tool: A Sentinel-1 orbit file downloader added, which allows to populate and/or update the orbit repository.
  • The Sentinel Downloader now supports automatic resuming to avoid re-downloading portions of files already downloaded.
  • DeGrandi filtering speedup and incremental processing support.
  • ScanSAR interferometry (TSX e PALSAR2) support.
  • New tool: Ship detection.
  • New tool: Moving target detection.
  • New coherence workflows.
  • Automatic SRTM-1v3 DEM (1 arcsecond) extraction and mosaicking.
  • SBAS and CCD cluster products available on request (new license needed).
  • It is now possible to check for the availability of new patches directly from the SARscape menu.
  • The SARscape processing functionalities are now available through the ENVI Task System.

Please note: SARscape 5.4.0 is only compatible with ENVI 5.4.

Sentinel-1

  • The Sentinel Downloader now supports automatic resuming to avoid re-downloading portions of files already downloaded.
  • Sentinel-1 import improvement:
    • Possibility to import only one polarization in case of dual-pol data.
    • The creation of a multilooked power image (_pwr) can be disabled.
    • If a geographic polygon shapefile (lat/lon coordinates) is provided in the optional files tab, only the bursts intersecting or included in this polygon will be imported.
    • Automatic mosaic of consecutive acquisitions. If in the input list there are some consecutive acquisitions (along the same relative orbit), the imported data will be automatically mosaicked.
  • Download of Sentinel-2 data.
  • Download tool for Sentinel-1 orbit files, allowing to populate or update the local orbit repository.
  • The Sentinel Downloader can download .kml preview files for Sentinel-1 SLC and GRD data.

General

  • It is now possible to check for the availability of new patches directly from the SARscape menu.
  • Preferences now allowing the creation of Quick Look also in PNG format.
  • Support for Hungarian Cartographic System.
  • Phase to Height step now allows to have DEM results in ellipsoidal and/or geoidal heights.
  • SARscape Import module inserted in the ENVI menu "Open As>SARscape".
  • Some import tools allow the insertion of several input files nested in sub-directories by using the “add folder” function in the input file list and selecting the folder containing all the sub-directories. This can be used, for example, to select a large amount of Sentinel’s manifest.safe files during the import of a stack of images.
  • Preferences now allowing to disable the automatic display of results (helpful in case of a large number of images).
  • View SARscape header file.
  • New default preferences added: “Squinted Data” and “TSX_ScanSAR”.
  • Integrated OpenCL CPU-only runtime updated to Intel version 16.1.1 (Windows only).
  • New “Diagnostics>Check OpenCL config” menu under “Administration” to quickly check the selected OpenCL platform/device.
  • The SARscape processing functionalities are now available through the ENVI Task System.

Import

  • Radarsat-2 import tool now supports NITF format.
  • Import Tiff now supports Tiled tiff and RGB.

General Tools

  • It is now possible to extract SRTM-1v3 DEM (1 arcsecond).
  • User Geoids Management. The user can now import and manage his/her own geoids files and these can be used in the supported processing steps (phase to height).

Basic Module

  • New tool: Ship Detection.
  • New tool and new workflow: Moving Target Detection.
  • New Coherence workflows:
    • Coherence CCD Timeline Workflow.
    • Coherence MTC RGB Workflow.
    • Coherence COV-PWR-CC RGB Workflow.
  • DeGrandi filtering speedup and incremental processing support.
  • For multitemporal features giving maximum/minimum values (Min, Max, Min Ratio, Max Ratio) an image showing the date of the chosen pixel is created (generate dates flag).

Interferometry Module

  • Cluster Coherence CCD Workflow (available for SARscape Cluster product).

Interferometric Stacking Module

  • SBAS Cluster (available for SARscape Cluster product).
  • PS processing speedup.

Interferometry ScanSAR Module

  • ScanSAR interferometry now supports TSX and PALSAR2 (full aperture).

End-of-Life (EOL) announcement

  • With SARscape 5.4, the focusing module for ENVISAT WS and ENVISAT AP reached endof- life. This module will no longer be available starting from the next SARscape (sub-)release.

Known Issues

The following list contains minor issues that are known and will be solved in forthcoming SARscape versions:

  • In some circumstances, a longitudinal shift between a geocoded SLC and a geocoded GRD in Sentinel-1 data can be seen (in the order of 10 m).
  • ScanSAR interferometry with PALSAR2 scanSAR in burst mode is not supported.
