Extraction of Land Use from Remote Sensing Images in Dalian Economic and Technological Development Zone Based on IDRISI
Based on the idrisi,this study select the 1 to 5 and 7 band data about TM whit 2002,using supervised classification to extract the land use classification on the Dalian Economic and Technological Development Zone.After selected training zone,used vectorization on landuse,then extract the spectral characteristics,generate the spectral signature files,extract landuse study area using by MINDIST. Finally extracted Dalian Economic and Technological Development Zone in 2002 land use distribution image, and makes analysis and evaluation.
