A Novel Urban Composition Index Based on Water-Impervious Surface-Pervious Surface (W-I-P) Model for Urban Compositions Mapping Using Landsat Imagery

Abstract: Monitoring urban compositions spatially and temporally is a crucial issue for urban planning and management. Nowadays, remote sensing techniques have been widely applied for urban compositions extraction. Compared with other remote sensing techniques, spectral indices have significant advantages due to their parameter-free and easy implementation. However, existing indices cannot extract different urban compositions well, and some of them can only extract one composition with less attention to other urban comp… Show more

“…As a simplistic urban composite index, UCI has better user accuracy and commission error values but lacks in all other aspects of accuracy metrics. Although Zhang, Tian and Liu [15] found overall accuracy is 0.931 and a Kappa coefficient of 0.89, this study uses random sampling points. It gets overall accuracy of 0.830 and a Kappa coefficient of 0.660 for Beijing city.…”

“…The land cover difference depends on the specific condition of the urban areas. Some researches have divided urban areas into some classes such as vegetated areas, built-up areas, agricultural, bare, and scrublands [23]; bare land, built-up area, vegetation and water [30]; or bare soil with low vegetation density, built-up, vegetation, and water body [3].…”

“…S one of the significant components of terrestrial water storage, surface water maintains diverse and complex societies and ecological systems [1][2][3]. Urban surface water is a vital indicator for flood monitoring [4][5], urban hydrological evaluation [6][7][8], and urban heat island effect assessment [9][10] and plays a significant role in urban planning. Given the background that the rapid urbanization Q. Liu, Y. Tian, and L. Zhang are with the School of Geography and Information Engineering, China University of Geosciences, Wuhan, 430074, China (e-mail: lqwei@cug.edu.cn; ygangtian@cug.edu.cn; zhanglihao@cug.edu.cn) process has caused dynamic changes in water bodies, it is of great significance to obtain the water body information and its spatio-temporal distribution quickly and accurately [11][12].…”
