- April 2nd, 2024:
- ATCOR-4 version 7.5 is released.
We are happy to release today the newest version of our airborne atmospheric correction software ATCOR-4. What is new?
- The default option of calculating the AOT(550nm) map is based on reference DDV (Dense Dak Vegetation) pixels and the average AOT is assigned to the non-DDV pixels.
- If a scene does not have enough DDV pixels (minimum 2 percent of pixels), a DDVS algorithm (DDV Substitute) is automatically executed using relaxed vegetation conditions but avoiding overcorrection of surface reflectance spectra.
- The AOT map over water bodies is calculated independently with the assumption of a water surface reflectance of 0.01 in the near-infrared (around 850 nm) spectrum.
- Optionally, an external AOT(550nm) map can be used. It has to fit the image size (columns, lines). The data can be 32-bit float, or AOT scaled with a factor 1,000 and stored as signed 16-bit integer or unsigned 16-bit integer. If the scene is named "scene.bsq" then the external AOT file is "scene_aot550.bsq" with a corresponding "scene_aot550.hdr".
- The dehaze program contains an improved definition of the ’bright’ pixels, where the haze thickness has to be spatially interpolated.
- The range-dependent adjacency correction (up to 5 adjacency zones) is now also supported for batch jobs.
- The calculation of the water vapor map with the option of band regression now also supports the combination of bands from the 940 nm region and the 1130 nm region.
- The de-shadowing with the matched filter algorithm is improved for batch processing and includes some iterations and plausibility checks.
- Improved BREFCOR correction for better masking and generic model.
- New TELOPS Hyper-Cam LW import.
- Updated ITRES CASI, AVIRIS-NG, and SPECIM AISA import functions.
- Consolidated and updated topographic correction methods.
End users with an active maintenance contract by April 2nd, 2024 are entitled to a free upgrade to this version. Please contact us to receive update instructions. A new license file will be issued only upon request. In case you do not have an active ATCOR maintenance contract, you may apply for a free evaluation license.

- ATCOR-3 version 9.5 is released.
- The processing of hyperspectral sensors now includes Prisma, EnMAP, and EMIT.
- Earthscan and Pleiades NEO support was improved.
- Improved TIFF file import and image display.
- The default option of calculating the AOT(550nm) map is based on reference DDV (Dense Dak Vegetation) pixels and the average AOT is assigned to the non-DDV pixels. Now a spatial interpolation option of the AOT(550nm, DDV) is available using an inverse distance weighting. It requires a somewhat more execution time.
- If a scene does not have enough DDV pixels (minimum 2 percent of pixels), a DDVS algorithm (DDV Substitute) is automatically executed using relaxed vegetation conditions, see chapter 'Aerosol Retrieval' of the separate ATBD document..
- The AOT map over water bodies is calculated independently with the assumption of a water surface reflectance of $0.01$ in the near-infrared (around 850 nm) spectrum..
- The dehaze program contains an improved definition of the 'bright' pixels, where the haze thickness has to be spatially interpolated. For hyperspectral sensors a channel near 424 nm and 440 nm is used for the haze thickness map calculation.
- The range-dependent adjacency correction (up to 5 adjacency zones) is now also supported for batch jobs. The corresponding parameter is included in the '*.inn' file.
- The calculation of the water vapor map with the option of band regression now also supports the combination of bands from the 940 nm region and the 1130 nm region. Previously, it was only one of the two regions.
- Septempber 4th, 2022:

- September 26th, 2021:
- ATCOR-4 version 7.4 is released.
- No topographic correction is performed for regions below clouds.
- The de-shadowing with the matched filter algorithm is improved for batch processing and includes some iterations and plausibility checks. So it usually performs better than the module with the graphical user interface. However, over-/under-correction of cloud shadow areas is still possible and this remains an interesting research topic for the future.
- Improved BREFCOR correction for better masking and generic model use.
- New Itres CASI import function, updated AVIRIS-NG and Specim AISA import functions.
- Consolidated and updated topographic correction methods.
- Multiple small updates for image display, processing, mosaicking, and reflectance based product generation.
- July 7th, 2021:
- ATCOR-3 version 9.4 is released.
- The classification algorithm is updated: The decision rules for water detection are modified. In addition, the buffer for cloud pixels is slightly increased.
- The AOT(550nm) map is improved: Now a spatial interpolation option of the AOT(550nm, DDV) is available using an inverse distance weighting which reduces the memory requirements.
- A DDVS (DDV Substitute) algorithm is tried if dark dense vegetation (DDV) fails. In many cases it yields better results than the default constant visibility option. If both algorithms (DDV and DDVS) fail, then the default visibility of 23 km is reset to 40 km to avoid an overcorrection. The optional AOT inverse distance weighting is also applied in case of DDVS.
- If the scene contains water bodies, an aerosol retrieval over water is additionally performed.
- Elevation-dependent cirrus removal is performed for sensors with a cirrus band around 1.38 µ m (Landsat-8,-9, Sentinel-2).
- No topographic correction is performed for regions below clouds.
- The de-shadowing with the matched filter algorithm is improved for batch processing and includes some iterations and plausibility checks. So it usually performs better than the module with the graphical user interface. However, over-/under-correction of cloud shadow areas is still possible and this remains an interesting research topic for the future.

Founded in 2000 by Dr. Daniel Schläpfer as a spin-off of the University of Zurich, the company reaches this important milestone on July 1st. The ReSe team stands ready as ever to deliver powerful solutions to address new challenges and data processing improvements. And there is so much more for us and for you to look forward to, as we continue to create and build our dynamic pipeline of innovations.
Major updates in this release are support for headless batch operation, automatic boresighting routines, tilted sensor support, dual sensor merging, and more:
What's new:
MODO-6 is a rewrite of our MODO 5 software to support the new MODTRAN 6 radiative transfer model.
It is to note that MODO-6 is meant as our future development platform and will be adapted for upcoming changes and updates to MODTRAN-6. On the other hand,MODO-5 is still available for some time. For now, the physical differences between the two models are mostly negligible for remote sensing applications. Therefore, MODO-5 remains available for research purposes in its current state.
