Assessment of Impervious Surface Estimation Techniques

Journal of Hydrologic Engineering, 2009
Impervious surfaces have been identified as a reliable indicator of the impacts of development on water resources. Research has found that imperviousness has a direct effect on local surface water as well as indirect effects on downstream receiving waters.

Analysis of Different Sensor Performances in Impervious Surface Mapping

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The U.S. Geological Survey (USGS) has developed the National Land Cover Database (NLCD) to provide consistent land cover and land cover change products for the nation since 2001. As one of products in the NLCD, the percent impervious surface area (ISA), which was estimated with Landsat imagery, represents the fraction of human-made impervious area in a

Impervious surface mapping using satellite remote sensing

IEEE International Geoscience and Remote Sensing Symposium, 2003
Landsat TM data have been used to map the percentage of impervious surface area of the seven-county Twin Cities Metropolitan Area in 1991, 1998 and 2000. Following classification of land cover types, a regression model relating percent impervious surface area to "tasseled cap" greenness was used to estimate the percent impervious surface area for ...

Impervious Surface Methodology: A Methodology for Defining and Assessing Impervious Surfaces in the Raritan River Basin

2000
In an effort to estimate and evaluate impervious cover throughout the Raritan Basin, this methodology was developed to explore the technical and policy decisions involved in the estimation process. This methodology defines impervious surface areas, states reasons to be concerned about impervious cover, and presents several methods of deriving ...

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 ...

Impacts of impervious surface on watershed hydrology: A review

Urban Water Journal, 2005
Increased impervious surface area is a consequence of urbanization, with correspondent and significant effects on the hydrologic cycle. It is intuitive that an increased proportion of impervious surface brings with it shorter lag times between onset of precipitation and subsequently higher runoff peaks and total volume of runoff in receiving waters ...

Aggregate selection and cost for impervious surface reduction

Urban Water Journal, 2013
This paper investigates the possibility that some aggregate gradations could be considered functionally ‘pervious’, based on comparison of an aggregate's permeability with either natural soil permeabilities or local rainfall intensities. Permeability was estimated by calculation for 27 American standard gradations, based on their porosity, coefficient ...

Factsheet #3: The Impact of Impervious Surfaces

2000
Impervious surfaces are areas of the earth that have been covered by any material that impedes the infiltration of water into the soil, including areas covered by pavement or buildings. The addition of impervious cover decreases the amount of groundwater recharge and increases the amount of stormwater runoff.
