| Abstract: | In order to study "Beijing 1" micro-satellite image application potential in land use field,image quality was studied through analysing visual quality,spectrum characteristics,noise characteristics and geometry correction precision;the image land use classification precision was studied through selecting characteristic variable,optimizing training sample,establishing classification template,constructing Maximum Likelihood and Mahalanobis to make land use classification and appraising the classification precision.The results show that "Beijing 1" micro-satellite image quality is fine and land use classification precision is high.Image can become the main data source that remote sensing data renews in land use research. |
