    Stevenson, Megan; Kolivras, Korine (Virginia Tech, 2019-04-26)
    Lyme disease has been a growing problem in the United States over the last few decades, and is currently the most common vector-borne disease in the country. This research evaluates the land cover within specified counties ...
  • Renewable Energy Facility Siting Project 

    McKnight, Molly (Virginia Tech, 2019-04-26)
    The American public has become increasingly concerned about climate change. These concerns over the environment and the desire to decrease energy reliance on other countries have resulted in America’s pursuit of renewable ...
  • Assessing Seasonal Changes of Spatial Complexity in Riverscapes using Drone-Based Laser Scanning 

    Aquilina, Charles; Hession, W. Cully; Lehman, Laura; Resop, Jonathan (Virginia Tech, 2019-04-26)
    Light detection and ranging (lidar) is a form of remote sensing using laser pulses to measure distances. Recent advancement in lidar technology has made units small enough to mount on drones, which makes high-quality data ...
  • Digital Transformation: Possibilities for a Geo-Enabled Campus 

    Miller, Geri (Virginia Tech, 2019-04-26)
    A Geo-enabled Campus is a campus where everyone is empowered with access to geospatial tools, data, and technologies, embracing all aspects of a campus’ teaching, research, and administration. There are a lot of possibilities ...
  • Attribute Standardization of Car Crashes and Its Potential Uses 

    Mitchell, Allison; Hamilton, Lonnie, III; Newman, Joseph (Virginia Tech, 2019-04-26)
    The primary focus of our research endeavor centers around standardizing the spatial attributes of police-reported crash records in the Commonwealth of Virginia. The Center for Geospatial Information Technology at Virginia ...
  • Multi-temporal Multi-sensor Data Fusion 

    Ghannam, Sherin; Abbott, A. Lynn (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 ...
  • Producing a Canopy Height Map Over a Large Region Using Heterogeneous LIDAR Datasets 

    Gopalakrishnan, Ranjith; Thomas, Valerie A.; Coulston, John; Wynne, Randolph H. (2014)
    Accurate and unbiased wall-to-wall canopy height maps for large regions are useful to forest scientists and managers for several reasons such as carbon accounting and wildfire fuel-load monitoring. Airborne lidar is ...
  • Waldo Canyon Fire 

    Garza, Mario; Freeman, Sam (2014)
    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 ...
  • 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 ...
  • 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 ...
  • 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- ...
  • Investigating Forest Conversion Across Several Scales of Urbanization in the Eastern United States 

    Wu, Yi-Jei; Thomas, Valerie A.; Oliver, Robert D. (2014)
    Urbanization in the United States has clearly impacted land cover, and land use and land cover change (LULCC) patterns. A great body of literature has addressed the negative results of increased sprawl and a supporting ...
  • Crowds for Clouds: Using an Internet Workforce to Interpret Satellite Images 

    Yu, Ling; Ball, Sheryl; Blinn, Christine E.; Moeltner, Klaus; Peery, Seth; Thomas, Valerie A.; Wynne, Randolph H. (2014)
    A chronologically ordered sequence of satellite images can be used to learn how natural features of the landscape change over time. For example, we can learn how forests react to human interventions or climate change. ...
  • 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 ...
  • 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 Congress 

    Vaughan, Matthew; Rouzer, Sarah (2014)
    Historians are increasingly coming to believe that space matters. From claims that "geography is destiny" to the long-held belief that "all politics is local," understanding the implications of space--the spatial turn--is ...
