- August 31st, 2011:
- PARGE version 3.1 has been released. Information about this release:
- Added completely revised ENVI file display routines including the display of BIP/BIL imagery, enhanced image export capabilities, true color display, coordinate selection, exact cursor placement, spectral data display and export, and more,
- added integrated processing for dual sensors, i.e., the data from any two sensors
flown from the same aircraft may be integrated into one rectified output file,
- added mosaicing output option as part of the integration processor (restricted to
two image scenes),
- added automatic generation of scan angle file in rectification process,
- included possibility to import GCP coordinates from Google Earth KML,
- added support for Resonon-PIKA System,
- improved support for Hymap and Hyspex system,
- added option for flagging missing columns in sensor file,
- added support for spatial binning in resampling routines, i.e. the original data can be binned spatially if the target resolution is more than a factor of 2 below the acquisition resolution,
- fixed problem with rgb creation in bilinear interpolation and updated the direct RGB display routine,
- revamped amd fixed scan angle creation routine,
- added ENVI GLT export function,
- added illumination calculation in ATCOR preparation routine,
- improved and fixed atcor preparation routine for raw geometry processing,
- bug fixes: Swiss coordinate conversion fixed, removed artifacts for tiled processing and when creating background mask,
- updated the free TRAFO software for file display and final georectification, and
- updated PARGE User Manual to reflect recent changes in GUI and in the routines.
- April 8th, 2011:
- ATCOR-3 version 6.0 and ATCOR-4 version 8.0 have been released. Information about this versions:
- The high resolution atmospheric database was re-compiled with the MODTRAN®5 code using a 0.4 nm
spectral grid instead of the previous 0.6 nm based on MODTRAN4. This improves the accuracy
of the atmospheric look-up tables and expands the applicability of ATCOR to hyperspectral
instruments with bandwidths as small as about 2 nm.
A high accuracy is also obtained by performing the calculations with the correlated k algorithm
in atmospheric absorption regions.
- A tool is provided to convert the monochromatic atmospheric database from one extraterrestrial spectral
solar irradiance to another irradiance source. This enables the utilization of user-supplied spectral irradiance
files if the spectral coverage, increment, and irradiance unit agree with the template irradiance.
The delivered (0.4 nm) database uses the Fontanla-2011 solar irradiance spectrum for a quiet or low activity sun instead of the former Kurucz-1997 irradiance.
This feature is of interest for the hyperspectral version or for user-defined sensors with a
narrow spectral bandwidth.
- For sensors affected by the "spectral smile" effect a new postprocessing tool is available which
interpolates the surface reflectances to a common user-specified wavelength, such that
the pixel reflectances for each channel finally belong to the same center wavelength.
- A new algorithm has been included to remove haze over water using a separate water map.
The algorithm for haze removal over water is also able to eliminate sunglint over water (ihaze=4).
- The surface reflectance ratio of the blue-to-red band for the dense dark vegetation (DDV) algorithm is
included in the '.inn' file. The default is (blue) / (red) = 0.5$. The value was fixed in
previous versions, but can now be specified by the user.
- The size of the low pass filter box for the water vapor map is now specified in meters (instead of the previous
choices of no filtering or fixed filter size), see the menu for the "preference parameters".
- There is an option for rugged terrain imagery to reduce over/under-correction in cast shadow areas, see the
"preference parameters" menu.
- A new derivate filter for polishing hyperspectral data has been indluced.
- The integration of new sensors is eased by a new sensor definition panel.
- The ENVI image display routine has been improved including the ability to select and export image spectra and profiles from BSQ imagery.
- A new parameter in the ".inn" file allows the calculation of the global solar flux image
(flat terrain) as well as images of the direct and diffuse solar flux on the ground (rugged terrain).
- The sensors GeoEye-1 and WorldView-2 are included for atmospheric correction in ATCOR-3.
- February 27th, 2011:
- MODO version 5.0 has been released. Information about this version:
- Data structure to fully support MODTRAN® 5.
- Included Simple Atmospheric Correction Routine (SACO) for ENVI imagery
- Added ENVI file display and Spectrum Analysis routine
- Updated plotting and display routines,
- Integration with existing MODTRAN® 5 installation, and
- New spectral shift calculation routine.
- September 23rd, 2010:
- MODO version 4.0 has been released. Information about this version:
- Revised and extended internal data structure for an improved user experience,
- Updated plotting and display routines,
- New spectral shift calculation routine,
