Accuracy Assessment of the National Land Cover Database Impervious Surface dataset for Roanoke, Virginia
(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 ... -
Accuracy Assessment of the NLCD 2006 Impervious Surface for Roanoke and Blacksburg
(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 ... -
Analysis of Crop Phenology Using Time-Series MODIS Data and Climate Data
(2014)Understanding crop phenology is fundamental to agricultural production, management, planning and decision-making. In the continental United States, key phenological stages are strongly influenced by meteorological and ... -
Application of GIS and RS in Abandoned Land Surveying: A Case Study in Shandong, China
(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. ... -
Application of SEBAL Model for Mapping Evapotranspiration in Iowa Using MODIS Time-Series Data
(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
(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 ... -
A Climatology of Precipitation Efficiency for the Central Appalachian Mountains Region
(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 ... -
Crowds for Clouds: Using an Internet Workforce to Interpret Satellite Images
(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. ... -
Delineating Subwatersheds within the Monongahela National Forest: The Implications of a Watershed Approach on Forest Planning
(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 ... -
Ecosystem Service Benefits from Public and Private Conservation Lands
(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 ... -
The Effect of Protected Wilderness Spaces on Local Human Population
(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 ... -
Elevation's Effect on Winter Weather
(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 ... -
Floodplain Hydraulics: LiDAR Applications
(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 ... -
Investigating Forest Conversion Across Several Scales of Urbanization in the Eastern United States
(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 ... -
Locations for a Trader Joe's in Roanoke , VA
(2014)By using data obtained from the City of Roanoke GIS Office and online real estate listings, we were able to pinpoint four locations within Roanoke where Trader Joe's could develop a store. We also considered proximity to ... -
Lyme disease and the wilderness-urban interface in North Carolina and Virginia
(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- ... -
Mapping Congress
(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 ... -
Mapping High Tunnels in the Local Food Systems
(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 ... -
Mapping Stable Nitrogen Isotopes Using Hyperspectral Imagery
(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 ... -
Multi-temporal forest change detection in central Sumatra
(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 ...
