Estimating impervious surface distribution by spectral mixture analysis
Estimating the distribution of impervious surface, a major component of the vegetation–impervious surface–soil (V–I–S) model, is important in monitoring urban areas and understanding human activities. Besides its applications in physical geography, such as run-off models and urban change studies, maps showing impervious surface distribution are essential for estimating socio-economic factors, s...
متن کاملEstimating Impervious Surface Distribution: A Comparison of Object Based Analysis and Spectral Mixture Analysis
Knowledge about the distribution of impervious surface is important to the understanding of urbanization processes and environmental consequences. This paper compares two methods for classifying the degree of imperviousness for the large metropolitan region of the fast growing city of Guangzhou in southern China: spectral mixture analysis (SMA) and object based image analysis (OBIA). Both metho...
متن کاملEstimating Urban Impervious Surfaces by Linear Spectral Mixture Analysis: A Case of Urban Area of Shanghai (2002-2008)
In recent years, impervious surface has emerged not only as an indicator of the degree of urbanization but also a major indicator of environmental quality. As one of the most important industry cities, Shanghai is rapidly increasing in population and area. The impervious surface expansion occurs through the encroachment into the adjacent and suburb land. Extracting information of impervious sur...
متن کاملImproving the Impervious Surface Estimation from Hyperspectral Images Using a Spectral-Spatial Feature Sparse Representation and Post-Processing Approach
Impervious surfaces have been widely recognized as an indicator for urbanization and environment monitoring. Plenty of methods have been proposed to extract impervious surfaces using remote sensing images. However, accurately extracting impervious surface is still a challenging task due to the confusion between impervious surface and bare soil. Thus, this paper presents a hybrid approach consis...
