July 1st, 2015: New releases of ATCOR
ATCOR 2/3 version 9 and ATCOR 4 version 7 are now available

This is to announce that major updates to ATCOR-3 and ATCOR-4 have been released.

The software packages include some major enhancements:

  • An all new haze removal algorithm has been added which works on the raw DN data by statistical analysis.
  • The wavelength reference of an instrument depends on the refractive index of air, this dependency has been considered for both spectral
  • calibration routines and image processing.
  • The high-resolution database is updated based on MODTRAN5.3.3 and HITRAN-2013 in- stead of the previous HITRAN-2009.
  • The column water vapor W=5 cm is included in the high resolution database (i.e., the *.bp7 and *.bt7 files) covering a larger water vapor range.
  • The thermal high-resolution database is updated with a higher spectral sampling distance of SSD=0.4 cm-1 for the wavelength region 7 - 10 micron.
  • For hyperspectral thermal instruments a spectral calibration )is offered based on the atmospheric absorption features present in the scene.
  • For hyperspectral thermal instruments, a new module 'estimate wv' may be used to calculate a water vapor column.
  • The import function for GEOTIFF and JPEG2000 variations have been updated and added.
  • The image based smile analysis tool has been improved and enhanced in various ways: more spectral features in the visible range have been added, an option to
  • search for the optimized FWHM has been added, and the overall accuracy has been improved by continuum removal based correlation.
  • The new installation process allows for direct updates and components installation from within the software.
  • A new batch call option has been added. This allows to call ATCOR through IDL within a processing environment directly from the computer console.
  • ATCOR-4 only: BREFCOR improvements: fixes and updates to interface and revamped/added sophisticated model analysis and plotting routines have been added.
  • ATCOR-3 only:
  • New sensors are supported: Worldview-3, WV-3 CAVIS, Gaofen-1/-2, Naomi-1, Landsat8 OLI, and upcoming Sentinel 2A.
  • The ozone influence in the 450 - 800 nm spectrum can optionally be included.
  • The cirrus removal is now also available without calculating the surface reflectance image.

Licensed users will obtain instructions as of how to upgrade their installation. Please contact us in case you're interested testing the new version.

July 25th, 2014: New release of PARGE
PARGE version 3.2 is now available

The new version of PARGE offers improved capabilities to ease the workflow. This is of special advantage for efficient processing of UAV scanner data.

Updated and new Features:

  • Direct processing function to produce rectified imagery right after data import in one step.
  • Support for global elevation data for automatic processing.
  • Pixel size calculation from IGM to optimize the output image resolution.
  • New mosaicking routine to automatically mosaic a number of rectified images to common grid.
  • Boresighting to arbitrary reference (by zeroing) added.
  • Improved DEM import functions.
  • Introduced PARGE LITE option for a reduced cost PARGE license, meant for automatic processing.
  • Support for ENVI coordinate system strings in outputs.
  • Further enhancements to ENVI file viewer and output scaling.
  • Bug fixes for processing of long flight lines.
  • Corrected treatment of saturation level in the processing and resampling for both binning and interpolation (uses the ENVI header tag 'data ignore value')
  • Fixed problems with southern hemisphere data processing.
 
December 10th, 2013: New release of ATCOR-4
ATCOR-4 version 6.3 is now available

ReSe includes the first universal BRDF correction method available on the market as part of the ATCOR software package. The BRDF effects correction method (BREFCOR) has been created for an unsupervised, model based BRDF correction of airborne wide FOV scanner data.

Further improvements in this release:

  • The aerosol retrieval with dense dark vegetation (DDV) was modified in two ways: firstly, a fixed offset is applied to the blue/red surface reflectance correlation (i.e. ρ0.48m = b ρ0.66m + 0.005, default b=0.5 ) and secondly, for deep blue channels ( < 0.48 μm) the DDV surface reflectance at 0.40 μm is set as ρ0.40 = 0.6 ρ0.48 with linear interpolation for tie channels between 0.40 and 0.48 μm. This feature modifies the path radiance of the selected aerosol model in the deep blue to red region to match the DDV surface reflectance in this spectral region, see chapter 10.4.2 for details. If the slope factor b is a negative value then the path radiance in the blue-to-red is not modified and agrees with the selected aerosol model.
  • A new de-shadowing algorithm is available besides the current matched filter algorithm. The new algorithm is based on the illumination file (* ilu.bsq’). If this file is coded as float and resides in the folder of the scene to be processed, then this de-shadowing algorithm is invoked, even for a flat terrain processing.
  • A tool for low pass filtering noisy target spectra (for inflight calibration) is added.
  • Another high resolution (0.4 nm) extraterrestrial solar irradiance spectrum is available based on the ’medium 2’ solar activity of Fontenla (named ’e0 solar fmed2 2013 04nm.dat’). It might be of interest for hyperspectral sensors. It could be used instead of the current Fontenla- 2011 irradiance file ’e0 solar fonten2011 04nm.dat’ and the associated the compilation of the high resolution database containing the ’*.bp7’ files.
  • A new tool has been added to resize external digital elevation data to the image size and to automatically calculate all side layers.
  • The new BRDF effects correction method (BREFCOR) corrects the effects of BRDF (solar and viewing geometry) using a continuous kernel based model. The method is applicable to airborne imagery with FOVs larger than approx. 15 degrees.
  • The flight-altitude interpolated LUT files '*.atmi' were always deleted in the previous verions. This caused a conflict if runs with the same flight altitude were processed in parallel batch jobs. Now, an editing of the preference parameter file allows to keep the '*.atmi' files on the sensor-specific sub-directory of the 'atm_lib' folder. The user should delete these files after processing the scenes of the campaign to avoid the accumulation of many temperay files.
 
November 3rd, 2013: New ATCOR release
ATCOR-3 version 8.3 is now available

Improvements in this release:

  • The aerosol retrieval with dense dark vegetation (DDV) was modified in two ways: firstly, a fixed offset is applied to the blue/red surface reflectance correlation (i.e. ρ0.48m = b ρ0.66m + 0.005, default b=0.5 ) and secondly, for deep blue channels ( < 0.48 μm) the DDV surface reflectance at 0.40 μm is set as ρ0.40 = 0.6 ρ0.48 with linear interpolation for tie channels between 0.40 and 0.48 μm. This feature modifies the path radiance of the selected aerosol model in the deep blue to red region to match the DDV surface reflectance in this spectral region, see chapter 10.4.2 for details. If the slope factor b is a negative value then the path radiance in the blue-to-red is not modified and agrees with the selected aerosol model.
  • A new de-shadowing algorithm is available besides the current matched filter algorithm. The new algorithm is based on the illumination file (* ilu.bsq’). If this file is coded as float and resides in the folder of the scene to be processed, then this de-shadowing algorithm is invoked, even for a flat terrain processing.
  • A tool for low pass filtering noisy target spectra (for inflight calibration) is added.
  • The Landsat-8 OLI sensor is supported, as well as the Pleiades and SPOT-6 sensors. The processing for OLI requires a layer-stack band-sequential file with bands B1 - B5, B9 (the new cirrus channel at 1.38 μm), then B6, B7, i.e. a wavelength ascending channel sequence, see chapter 9.6.2. An import module is available under ’File’, ’Import’, ’Landsat-8’ (OLI+TIRS) or ’Landsat-8 OLI’ (only OLI). ATCOR provides an optional cirrus correction for cirrus affected scenes. The panchromatic channel B8 has to be processed separately.
  • The Landsat-8 TIRS sensor is supported, and an approximate surface temperature product can be calculated from the thermal bands B10 and B11 using the split window technique, see chapter 9.6.3. The two thermal bands can be processed separately or together with the OLI bands, see the new import functions for Landsat-8 (’File’, ’Import’, ’Landsat-8’ or ’Landsat-8 OLI’).
  • The reader of the meta data file now also supports Landsat-8. Pleiades, and SPOT-6. It extracts the necessary data for the ’*.inn’ and ’*.cal’ files.
  • Another high resolution (0.4 nm) extraterrestrial solar irradiance spectrum is available based on the ’medium 2’ solar activity of Fontenla (named ’e0 solar fmed2 2013 04nm.dat’). It might be of interest for hyperspectral sensors. It could be used instead of the current Fontenla- 2011 irradiance file ’e0 solar fonten2011 04nm.dat’ and the associated the compilation of the high resolution database containing the ’*.bp7’ files.
  • A separate tutorial is available explaining how to use ATCOR without burdening the reader with the theoretical background.
  • A new tool has been added to resize external digital elevation data to the image size and to automatically calculate all side layers.
  • An new BRDF effects correction method (BREFCOR) has been introduced which corrects the effects of BRDF (solar and viewing geometry) using a continuous kernel based model. The method is applicable to satellite imagery if a number of images is acquired under varying observation angles to improve mosaicking.
