    • Floodplain Hydraulics: LiDAR Applications 

      Jones, C. Nathan; Scott, Durelle (2014)
      As climate becomes increasingly variable, the costs to infrastructure and our society as a whole are going to rise drastically. Since the year 2000, damages due to hurricanes are estimated to be ~$260 Billion in the United ...
    • Optimizing Measurement of 4G LTE Broadband Access in Virginia 

      Adams, Erica (2014)
      Wireless coverage is not confined to jurisdictional boundaries and populations are not distributed evenly within jurisdictions. However both population and coverage statistics are often reported at the jurisdictional scale. ...
    • The Effect of Protected Wilderness Spaces on Local Human Population 

      Griffin, Drew; Duda, Kaylyn; Brosch, Geoff (2014)
      The goal of this project is to analyze the effect that protected wilderness areas have on local human populations through the use of GIS. Using data from Northern Tanzania and from Virginia we hope to discover the degree ...
    • Accuracy Assessment of the National Land Cover Database Impervious Surface dataset for Roanoke, Virginia 

      Parece, Tammy E.; Campbell, James B. (2014)
      The Multi-Resolution Land Characteristics Consortium (MRLC) developed National Land Cover Database Impervious Surface (NLCD IS) data to identify percent developed imperviousness for the coterminous USA. We present the ...
    • Application of GIS and RS in Abandoned Land Surveying: A Case Study in Shandong, China 

      Li, Jing; Liu, Zishang; Li, Wenyu (2014)
      For the acute contradiction between land and people, cherishing and reasonable using per inch land is a persistent national policy in China, whereas land damage is unavoidable in mining, construction and other activity. ...
    • A Climatology of Precipitation Efficiency for the Central Appalachian Mountains Region 

      Morrow, James; Luchetti, Nick (2014)
      Precipitation efficiency is commonly defined as the ratio of the amount of precipitation at ground level to the amount of precipitable water in the column of the atmosphere above. The value represents the fraction of ...
    • A Study of Impermeable Surfaces in the Greater Washington, D.C. Area 

      O'Connor, Mary; Chase-Walsh, Sarah; Cerquiera, Stephen (2014)
      The Washington D.C. area, like many cities, is covered with impermeable surfaces. With millions of cars on the roads every year, runoff is a major problem for the Potomac and the Anacostia rivers, which both empty into the ...
    • Ecosystem Service Benefits from Public and Private Conservation Lands 

      Scott, L.; Gillespie, J.; Villamagna, A. (2014)
      Research Objective: To quantify and compare ecosystem services (ES) capacity for Publicly Protected Areas (PPAs) and private conservation easements. Method: The study area was state and federal PPAs and private conservation ...
    • Mapping Stable Nitrogen Isotopes Using Hyperspectral Imagery 

      Correll, Katie; Strahm, Brian; Thomas, Valerie A. (2014)
      As nitrogen deposition increases globally, ecosystem changes will occur. It is important to understand the growth response of different ecosystems and where nitrogen retention will occur. Stable isotopes of foliar nitrogen ...
    • Accuracy Assessment of the NLCD 2006 Impervious Surface for Roanoke and Blacksburg 

      Zhao, Suwen; Feng, Leyang; Shao, Yang; Dymond, Randel L. (2014)
      Impervious surface map products are important for the study of urbanization, urban heat island effects, watershed hydrology, water pollution, and ecosystem services in general. At the conterminous US scale, impervious ...
    • Elevation's Effect on Winter Weather 

      Shiben, Elliot; Sult, Sierra; Allen, Bryan (2014)
      Because our group is made up of three meteorologists our ideas for our GIS based research naturally favored weather based ideas, so it was only right that our eventual idea coincided with this recent massive snow storm ...
    • Multi-temporal forest change detection in central Sumatra 

      Poor, Erin (2014)
      Forest conversion to oil palm plantations and development in central Sumatra has been rampant over the past two decades. Home to critically endangered species such as the Sumatran tiger and Sumatran elephant, continued ...
    • Mapping High Tunnels in the Local Food Systems 

      Foust-Meyer, Nate; O'Rourke, Megan E. (2014)
      High tunnels (HTs) represent a quietly growing, local level response to globalization of the food system. As semi-permanent greenhouses, HTs bring practical on-farm solutions to biophysical growing constraints; they extend ...
    • Application of SEBAL Model for Mapping Evapotranspiration in Iowa Using MODIS Time-Series Data 

      Feng, Leyang (2014)
      Evapotranspiration (ET), including evaporation from soil surface and vegetation transpiration, is an important variable for water and energy balances on the Earth's surface. Quantifying evapotranspiration (ET) from agriculture ...
    • Automated Landsat Classification of Tropical Forest Disturbances for Large Scale Identification in the Amazon 

      Derwin, Jill (2014)
      Under-reporting of selective logging and forest disturbance has posed an issue for forest health and deforestation estimations in the tropics due to difficulty of detection by satellite data. Several studies have proposed ...
    • Lyme disease and the wilderness-urban interface in North Carolina and Virginia 

      Zajic, Katherine (2014)
      Lyme, a tick-borne disease, has been endemic in Northeastern America for decades. However, with changing development patterns it is becoming a concern in areas where it was not previously endemic. Areas with high herbaceous- ...
