and bare bedrock covers, but the tied-SWIR2 region provides 
verifiably accurate estimates of PV, NPV and bare bedrock. 
AutoSWIR is a useful model to resolving spatial heterogeneity 
of vegetated landscapes in karst ecosystem. Hyperspectral data 
can provide a powerful methodology toward understanding the 
extent and spatial pattern of karst rocky desertification in 
Southwest China.
