| Abstract: | This paper made a research on Laizhou,lying in the east coast of Laizhou Bay.Adopting TM images as the main information source,and based on the analysis of various surface features,a layered information extract method based on the light spectrum,terrain and other knowledge was raised,combined with the district features,surface features and light spectrum features,and comprehensively utilized the two-period typical seasonal aspect remote sensing images.The results showed that this method of layering was goal-oriented,with the obvious improvement of classification accuracy and computational efficiency.The analysis of data and the interpretation method were more flexible as well. |
