Method Research of Spatio-temporal Constraint Desertification Land Remote Sensing Extraction

ZHANG Feng;Basic Surveying and Mapping Institute of Liaoning Province;  
According to the characteristics of the mild desertification land in the Liaoning northwest,through analysis of the spectral characteristics,spatial distribution,and time change features of desertification land. A desertification land recognition method by using multi-spectrum remote sensing image and spatio-temporal constraint was studied. Based on the analysis of spectrum characteristics of the desertification land,spatio-temporal constraint correction was involved. This method effectively improves the accuracy and efficiency of land desertification monitoring.
