1 the intercalibration aims at the whole imagery or just the region you want to study?
2 the first step of intercalibration begins at transfering nighttime light data to ASCII in ENVI?then use spss?
3 I still don't understand why choosing F16-2007 as the reference
4 can I leave out A saturated light correction method for NTL data?
