Abstract :
Soil line is important foundation of several drought monitoring models based on spectra feature space. So the accuracy of soil line obtained of study area effect the accuracy of this type monitoring model. More research in factors of soil line, however, the study has yet been rarely involved, that the accuracy of the soil line affecting drought monitoring accuracy. This paper analyzed the accuracy of the soil line impacting the accuracy of drought monitoring, such as PDI, MPDI, SPSI and NPSI.
