Multisource Remote Sensing based Impervious Surface Mapping
Impervious surface (IS) not only serves as a key indicator of urbanization, but also affects the micro-ecosystem. Therefore, it is essential to monitor IS distribution timely and accurately. Remote sensing is an effective approach as it can provide straightforward and consistent information over …

Land Cover and Impervious Surface Mapping Using Multispectral Airborne Laser Scanner Data
Impervious surfaces are land covers that do not allow water penetration. Water runoff from impervious surfaces can cause major flooding in extreme climates; therefore, mapping such surface covers in urban areas is of great importance for water resources, climatology, and urban studies. Automated …

A GIS and Remote Sensing Based Analysis of Impervious Surface Influences on Bald Eagle (Haliaeetus leucocephalus) Nest Presence in the Virginia Portion of the Chesapeake Bay
… and land type, distance to land type and impervious surface cover area. Data plots revealed bald eagle nest presence decreases in response to an increase in area of bareland; increases with an increase in area of forested land; decreases with an increase in distance (m) to shoreline, and …

Investigating Historical and Contemporary Land Cover Effects on Macroinvertebrate Communities and Water Quality of Virginia Piedmont Streams
… Historical (1963) and contemporary (2011) impervious surface, open area, and forested cover were evaluated using aerial photos and GIS data. Macroinvertebrates were collected in the fall of 2012 and spring of 2013. Water quality parameters (temperature, conductivity, alkalinity, hardness, …

A Comparison of Imperviousness Derived from a Detailed Land Cover Dataset (DLCD) versus the National Land Cover Dataset (NLCD) at Two Time Periods
… Cover Dataset (NLCD), this case study compares impervious surface from the NLCD to a Detailed Land Cover Dataset (DLCD) for the Town of Blacksburg, Virginia over two time periods (2005/2006 and 2011) at spatial aggregation scales (fine to coarse) and scopes (site-specific to area-extent). When …

Impervious Surfaces Mapping Using High Resolution Satellite Imagery
In recent years, impervious surfaces have emerged not only as an indicator of the degree of urbanization, but also as an indicator of environmental quality. As impervious surface area increases, storm water runoff increases in velocity, quantity, temperature and pollution load. Any of these …

Simulating urban growth for Baltimore-Washington metropolitan area by coupling SLEUTH model and population projection
… projection of 2050, aided by strong population-imperviousness statistical relationship (R2, 0.78-0.86), to predict total impervious surface area for each county. These population-predicted total impervious surface areas were compared to SLEUTH model output, at the county-aggregated spatial …

Variation in Salamander Life History and Community Composition Across an Urban Gradient in Atlanta, Georgia, USA
… a better predictor of stream temperature than impervious surface cover; 2) cooler August temperatures predicted a longer larval period and smaller larvae; 3) higher impervious surface cover predicted larger larvae and larger adult females; 4) larger females were associated with significantly …

HOW URBAN DEVELOPMENT CONTRIBUTES TO THERMAL ENVIRONMENT VARIATION ---- A CASE STUDY IN NEW YORK CITY
… to accurately measure over heterogeneous land surfaces. Here, relying on remote sensing technology and meteorological models, AHF is estimated and illustrated on April 18, 2017 over NYC area. Furthermore, a few independent variables are developed in order to possibly explain the variations of …

Does Urbanization Facilitate the Establishment of Introduced Monk Parakeet (Myiopsitta monachus) Populations?
… States. I used tree canopy cover and percent impervious surface data from the 2016 National Land Cover Database GIS layers, surface water features from the National Hydrography Dataset, and observations and location data from eBird to find nest locations that were then confirmed by Google …

Detecting Impervious Cover with Artificial Lighting in Astronaut Photography from the International Space Station
Impervious cover continues to pose a threat to flood-prone regions, especially the ones in dense urban areas. Mapping the location of impervious surface becomes vital to properly managing drainage and runoff in a city, along with the health of fluvial ecosystems. Kotarba and Aleksandrowicz, in …

Investigating the Role of Long Distance Dispersal in the Response of Stream Fishes to Urbanization
… a heavily impacted urban stream (watershed impervious surface cover ~30%) and a mildly impacted rural stream (watershed impervious surface cover ~6%). Species of interest were marked with 12mm HPT PIT tags and included a specialist, <em>Campostoma oligolepis </em>(n=189 urban site, 200 rural …

Development of a Hydrologic Model for an Urban Headwater Stream: The Influence of Pervious Surface Properties on Runoff Dynamics
… urbanization (over 90% developed, and almost 50% impervious surface area (ISA)). Selected datasets provided information on the stormwater drainage network, the physical attributes of the catchment and receiving waterway (i.e. drainage area, slope, etc.), infiltration potential of soil map units, …

An Experiment Assessing the Potential for Compost-Amended Lawn Topsoil to Inhibit Storm Quickflow
… challenges for the environment due to increasing impervious surface coverage enhancing quickflow discharge in the catchment. This makes increasing surface infiltration and soil water retention in urban areas a matter of high importance. Lawns, forming a substantial fraction of suburban space, are …
