Nov 8th, 2016: New release of ATCOR-4
ATCOR-4 version 7.1 is now available

What's new:

  • The high-spectral resolution atmospheric database 'atm database' was re-compiled based on MODTRAN5.4.0, including the 4 km surface elevation as a new grid point. It is recommended that users update the database as well as sensor-specific 'atm_lib' using the RESLUT module.
  • The tiled/batch processing can now be started from GUI including a console output.
  • Import of global DEMs has been improved such that it may be selected based on UTM coordinates.
  • A new import function for AISA data sets has been added
  • Online installation has been improved and adapted to new needs. Software startup calls are now logged on a ReSe Server to keep track of licensing (as long as an internet connection is active).
  • The haze removal ('dehaze') and cirrus removal ('decirrus') modules have been improved.
  • The ATCOR GUI supports the input of a negative visibility. This means the visibility is not changed during processing.
  • Added empirical correction options to ENVI file viewer.
  • A batch module is available to calculate the water vapor map, provided the corresponding '.inn' file exists. Previously, it was only available in the GUI mode.
  • An external aerosol optical thickness map (AOT550nm) is supported. If the file name of the input scene is 'scene_xxx.bsq', then the external AOT map should be named 'scene_xxx_aot550.bsq', and it replaces the internal visibility/AOT calculation.
  • Optional scene-dependent scaling of path radiance in the blue-green spectral region is possible for constant visibility.


Sept 14th, 2016: New release of ATCOR-3
ATCOR-3 version 9.1 is now available

What is new in the 2016 version:

  • The high-spectral resolution atmospheric database 'atm database' was re-compiled based on MODTRAN5.4.0, including the 4 km surface elevation as a new grid point.
  • Batch modules are available for the import of Landsat-4/-5, Landsat-7, Landsat-8, Sentinel- 2, RapidEye, Worldview-2, DMC, SPOT-4 to SPOT-7, and Pleiades data, see chapter 9.6. These runs can also be started with the 'File', 'Import' from ATCOR's graphical user interface (GUI).
  • An improved syntax allows batch calls from system console for complete scene processing.
  • Online installation has been improved and adapted to new needs. Software startup calls are now logged on a ReSe Server to keep track of licensing (as long as an internet connection is active).
  • ATCOR can be started from the GUI or a batch run for the above sensors can be started, e.g. 'landsat8 batch' or 's2 batch', which optionally includes dehazing.
  • For the batch processing of Sentinel-2 data it is recommended to use the 's2 batch' module, which accounts for the angular variation of solar and view geometry over the scene.
  • The haze removal ('dehaze') and cirrus removal ('decirrus') modules have been improved. If a narrow cirrus channel at 1.38 μm exists, the effect of cirrus clouds is also removed during the 'dehaze' run. Optionally, the 'dehaze' now performs a joint decirrus / dehaze, where the decirrus algorithm is executed first, followed by the dehaze.
  • The ATCOR GUI supports the input of a negative visibility. This means the visibility is not changed during processing.
  • A batch module is available to calculate the water vapor map, provided the corresponding '.inn' file exists. Previously, it was only available in the GUI mode.
  • An external aerosol optical thickness map (AOT550nm) is supported. If the file name of the input scene is 'scene xxx.bsq', then the external AOT map should be named 'scene xxx aot550.bsq', and it replaces the internal visibility/AOT calculation.
  • Optional scene-dependent scaling of path radiance in the blue-green spectral region is possible for constant visibility.


Sept 7th, 2016: New release of PARGE
PARGE version 3.3 is now available

The new version of PARGE offers enhanced support for batch processing and new automatization tools for rectification to orthophotos.

Updated and new Features:

  • Automatic GCP detection by correlation analyses of orthophotos to pre-rectified imagery.
  • New image stacking and resizing options.
  • New text file based batch processing support.
  • Batch callable PARGE from system console.
  • New console for GUI-based batch processing.
  • Larger flexibility for various data imports.
  • Final image warping option to optimize coregistration after integrated/dual instrument processing.
  • Full support for low altitude UAV processing, correcting self-overlay artifacts in imagery.
  • Integrated much improved ENVI image file viewer and spectral analysis tools (based on GLIMPS software).
  • Support for image stacking in mosaic tool
  • ... and various minor bug fixes ...


May 21st, 2016: MODO Version 5.2 released
MODO version 5.2 been released in support of the latest release of Modtran (version 5.4).

Modtran version 5.4 has been released recently. This is a maintenance release with higher speed and the latest HITRAN 2013 band models. We have updated our MODO software for supporting this latest (and probably last) release of Modtran 5. End users having acquired a MODO PRO license after May 1st 2015 are entitled for a free upgrade to MODO version 5.2 including an update of MODTRAN to the latest release. Please contact us if you are interested into bringing an older version of MODO and MODTRAN up to date.



April 5th, 2016: GLIMPS Version 1.0 Freeware released
The Free ENVI™ File Viewer GLIMPS Version 1.0 has been released

We are pleased to announce that the GLIMPS software is available for download now. The software is provided free of charge to anybody interested in remote sensing and hyperspectral image analysis. It is meant specifically for educational purposes.



October 9th, 2015: ATCOR-3 fully supports Sentinel 2
ATCOR 2/3 version 9 is updated for Sentinel 2A support

We are pleased to announce that as of today, the ATCOR 3 software package fully supports the processing of Sentinel 2A imagery in both 4band and 13 bands mode. A dedicated import function reads all required meta information while the processing can be accessed through the 'user-defined' ATCOR processing panels.
