    • 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 ...
    • 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 ...
    • 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- ...
    • Waldo Canyon Fire

      The Waldo Canyon fire was the most destructive wildfire in Colorado history (until the Black Forest Fire in 2013). The fire torched more than 340 houses and claimed at least two lives. It started on June 23, 2012 while the ...
    • Spatial Data for Agent-Based Wood Supply Chain Modeling 

      Kauffman, Joby; Prisley, Steve; Yao, Xiaozheng; Crescenti, Neil; Braff, Pamela (2014)
      The Center for Natural Resources Assessment and Decision Support (CeNRADS) in the College of Natural Resources and Environment at Virginia Tech has been tasked with developing tools, data, and knowledge for analyzing ...
    • 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 ...
    • Multi-temporal Multi-sensor Data Fusion 

      Ghannam, Sherin; Abbott, Lynn A. (2014)
      Landsat data offered a great help in mapping a lot of vegetation parameters at 30 m spatial resolution but unfortunately does not provide daily coverage (it has a 16 day revisit cycle). This is a major obstacle for monitoring ...
    • Spatial Methods for Broad-Scale Assessment of Deer Browse Impacts in Virginia 

      Kniowski, Andrew B.; Ford, W. Mark (2014)
      Biodiversity has become a central focus of conservation effort and research over the past several decades. Ungulates are important modifiers in many ecosystems and can significantly alter biodiversity. Throughout the eastern ...
    • The Understanding of Landscape Preference, Using Real Estate Appraisal as an Analyzing Tool 

      Ku, Yi Ning (2014)
      Along with urban development, the concept, preference, and ideality of aesthetics change, which could be related to the change of culture, education, age, etc. In fact, it is difficult to understand well about the direct ...
    • Spatial Analysis of Region Where FBI Headquarters May be Relocated 

      Kebede, Mussie (2014)
      The Federal Bureau of Investigation (FBI) recently shortened their list for relocation of their operational headquarters in Washington DC to two venues. The location currently in favor is an area in Springfield, Virginia. ...
    • Using Cloud Computing for Mapping Seasonal Landscape Fires in Eastern Zambia 

      Malambo, Lonesome; Heatwole, Conrad D. (2014)
      The availability of geospatial information has increased dramatically over the years and huge amounts of data are collected each day. Earth observation satellites such as Landsat deliver several hundred gigabytes of data ...
    • Delineating Subwatersheds within the Monongahela National Forest: The Implications of a Watershed Approach on Forest Planning 

      Rader, Kristin (2014)
      The Monongahela National Forest comprises over 900,000 acres of biologically diverse land in West Virginia. It is the largest tract of public land within the state, and it attracts anglers, hunters, and other outdoor ...
    • Northern Virginia Urban Sprawl Analysis Using Landsat Imagery and Demographic Data 

      Li, Gina (2014)
