Remote Sensing and the Environmental Quality of City

The environmental data of remote sensing is the basis of the preparation of maps and information with appropriate quality for the assessment of the change and evolution of the urban dynamic environment, which provides awareness of changes of details in relation to the characteristics of the studied area and effective parameters. The methods of combining the multiple parameters with other factors into one index have been studied, but due to the lack of criteria for precise evaluation, only general conclusions can be made. However, the large and significant correlation obtained from Combined GIS Method and Principal Component Analysis (PCA) indicate the compatibility between these two methods.
