A Soil and Impervious Surface Adjusted Index for Urban Impervious Surface Area Mapping

Photogrammetric Engineering & Remote Sensing, 2021
Index-based methods are widely applied to urban impervious surface area (ISA) mapping, but the confusion between ISA and soil remains unsolved. In this article, the near-infrared (NIR)-blue bands were selected as feature space by analyzing the spectra from the US Geological Survey spectral library, and a simple impervious surface ratio index (ISRI ...

Urban Area Impervious Surface Estimation by Subpixel Unmixing

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Urban impervious surface area (ISA) is a key index toward urban eco-system and sustainable urban planning strategy. In this paper, a subpixel approach is proposed to estimate urban ISA values using linear spectral mixture analysis (LSMA)-based hyperspectral imaging techniques.

Research on extraction method of urban impervious surface information

2015 23rd International Conference on Geoinformatics, 2015
Impervious surface is a character of urban areas. Its cover conditions, changing with urban development, have a great impact on the local climate, hydrology, and the surface energy flux of the city. Based on analyzing the theory of the principal component analysis (PCA), built up area index, linear spectral unmixing, and classification and regression ...

The Spatiotemporal Evolution of Urban Impervious Surface for Chengdu, China

Photogrammetric Engineering & Remote Sensing, 2021
The spatiotemporal evolution of an impervious surface (IS) is significant for urban planning. In this paper, the IS was extracted and its spatiotemporal evolution for the Chengdu urban area was analyzed based on Landsat imagery. Our experimental results indicated that convolutional neural networks achieved the better performance with an overall ...

Effects of Impervious Surface on the Spatial Distribution of Urban Waterlogging Risk Spots at Multiple Scales in Guangzhou, South China

open access: yesSustainability, 2018
An impervious surface is considered one of main factors affecting urban waterlogging. Previous studies found that spatial pattern (composition and configuration) of impervious surfaces affected urban waterlogging.

Fractal and multifractal characteristic of spatial pattern of urban impervious surfaces

Earth Science Informatics, 2014
Urban impervious surface (UIS) has been widely utilized to quantify urban expansion and assess environmental impacts of urbanization. In order to understand the complexity of spatio-temporal change of UIS spatial pattern, we investigated the fractal and multifractal characteristics of UIS spatial pattern in the downtown area of Shanghai, China during ...

Evaluation of Impervious Surface Estimates in a Rapidly Urbanizing Watershed

Photogrammetric Engineering & Remote Sensing, 2004
Accurate measurement of impervious surface (IS) cover is an essential indicator of downstream water quality and a critical input variable for many water quality and quantity models. This study compares IS estimates from a recently developed satellite imagery/land cover approach with a more traditional aerial photography/land use approach.

Impervious surface thresholds for urban tree site selection

Urban Forestry & Urban Greening, 2018
Abstract Impervious surfaces are a ubiquitous urban feature that increase temperature and tree drought stress and are a demonstrated indicator of Acer rubrum L. tree condition and insect pest abundance. We examined the relationship between A. rubrum condition, impervious surface cover, and Melanaspis tenebricosa (Comstock) abundance, a primary ...

Object-oriented extraction of urban impervious surface coverage

2011 2nd International Conference on Artificial Intelligence, Management Science and Electronic Commerce (AIMSEC), 2011
The urban impervious surface coverage is one of the criteria of a city's eco-environment rating system and it is of great importance by using remote sensing image. Take the example of Jiaozuo by using the technology of Landsat multispectral remote sensing image and object-oriented classification method, this paper get results of urban impervious ...
