Extract Method of Urban Greenbelt Based on TM Image

Abstract:

Based on remote sensing image, the spectral information of urban Greenbelt in Guangzhou City was extracted from TM image by ENVI4.7. After finishing image preprocessing, then used 4 methods (such as principal component analysis, tasseled cap transformation, the normalized difference vegetation index(NDVI) method, SOFM artifical neutral network method) extract greenbelt information of Guangzhou City, and compared the images produced by four methods, according to the actual situation of the study area, we find that SOFM neutral network has the best classification effect.
