     SetDocLongDescription("The application allows to convert pixel values from DN (for Digital Numbers) to physically interpretable and comparable values.Calibrated values are called surface reflectivity and its values lie in the range [0,1].\n The first level is called Top Of Atmosphere (TOA) reflectivity. It takes into account the sensor gain, sensor spectral response and the solar illumination.\nThe second level is called \emph{Top Of Canopy (TOC)} reflectivity. In addition to sensor gain and solar illumination, it takes into account the optical thickness of the atmosphere, the atmospheric pressure, the water vapor amount, the ozone amount, as well as the composition and amount of aerosol gasses.\n It is also possible to indicate an AERONET file which contains atmospheric parameters.");
