[المشرف العام]

Following are my procedure, observation and question/ request:

Data Source: Earth Explorer Landsat 8 Grass GIS Version: 7.0.2 RC1 Windows 7 32 bit OS

I have been trying to conduct an Atmospheric correction using the Grass wiki reference

a). Reflectance = REFLECTANCE_MULT_BAND_X(0.00002)*DN + REFLECTANCE_ADD_BAND_X (-0.1)


b). Reflectance with correction of sun angle = Reflectance/ Sin(
