Extraction and Analysis of Finer Impervious Surface Classes in Urban Area [PDF]
Impervious surfaces (IS), the most common land cover in urban areas, not only provide convenience to the city, but also exert significant negative environmental impacts, thereby affecting the ecological environment carrying capacity of urban agglomerations.

A Comparative Study of various Indices for extraction urban impervious surface of Landsat 8 OLI
Impervious surface is one of the major land cover types of urban and suburban environment. Conversion of rural landscapes and vegetation area to urban and suburban land use is directly related to the increase of the impervious surface area.

URBAN IMPERVIOUS SURFACE DETECTION WITH LANDSAT AND FULL POLARIMETRIC ALOS/PALSAR IMAGES [PDF]
Impervious surface detection in urban area is of great importance because impervious surfaces have been recognized as an urbanization index. In other words, an increase of impervious surface extent accounts for urban sprawl.
