Aladdin's Magic Lamp: Developing Methods For Calibration And Geolocation Accuracy Assessment Of The Dmsp Ols, Benjamin Taylor Tuttle
Aladdin's Magic Lamp: Developing Methods For Calibration And Geolocation Accuracy Assessment Of The Dmsp Ols, Benjamin Taylor Tuttle
Electronic Theses and Dissertations
Nighttime satellite imagery from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) has a unique capability to observe nocturnal light emissions from sources including cities, wild fires, and gas flares. Data from the DMSP OLS is used in a wide range of studies including mapping urban areas, estimating informal economies, and estimating urban populations. Given the extensive and increasing list of applications a repeatable method for assessing geolocation accuracy, performing inter-calibration, and defining the minimum detectable brightness would be beneficial. An array of portable lights was designed and taken to multiple field sites known to have no other …

This paper explores the potential of using Microsoft's Kinect to create a low-cost and portable system to virtually navigate, through a prototype 3D GIS, the digitally reconstructed ancient Maya city and UNESCO World Heritage Site of Copan in Honduras. The 3D GIS, named QueryArch3D, was developed as part of the MayaArch3D project (http://mayaarch3d.unm.edu), which explores the possibilities of integrating databases and 3D digital tools for research and teaching on ancient architectures and landscapes. The developed system, based on the Flexible Action and Articulated Skeleton Toolkit (FAAST), controls in a remote and touchless mode the movements in the 3D environment in …
Richard Edes Harrison And The Cartographic Perspective Of Modern Internationalism, Timothy Barney
Richard Edes Harrison And The Cartographic Perspective Of Modern Internationalism, Timothy Barney
Rhetoric and Communication Studies Faculty Publications
Air-age globalism was a discursive phenomenon throughout the development of World War II that accounted for the rapid “shrinking” of the world through air technologies and the internationalization of American interests. Cartography became air-age globalism’s primary popular expression, and journalistic cartographers such as Richard Edes Harrison at Fortune magazine introduced new mapping projections and perspectives in response to these global changes. This essay argues that Harrison’s mapping innovations mediate a geopolitical shift in America toward a modern, image-based internationalism. Through recastings of “vision” and “strategy,” Harrison’s work offers an opportunity to assess the rhetorical tensions between idealism and realism in …

Water Quality Trading Markets For The Kentucky River Basin: A Point Source Profile, Ronald Childress Jr.
Theses and Dissertations--Agricultural Economics
This study assessed the feasibility and suitability of a Water Quality Trading (WQT) program within the Kentucky River Basin (KRB). The study’s focal point was based on five success factors of a WQT program: environmental suitability, geospatial orientation, participant availability, regulatory incentive, and economic incentive. The study utilized these five success factors, geographical characteristics, and Discharge Monitoring Reports (DMR) to assess the feasibility of a WQT program.
The assessment divided the KRB into five eight digit Hydrologic Unit Codes (HUC), North, Middle, and South Fork, Middle Basin, and Lower Basin, to determine regional impacts caused by the nutrient PSs. Individual …
Myths And Measures: The Cultural Performance Of Portland’S Strip Club Identity, Wayne Coffey
Myths And Measures: The Cultural Performance Of Portland’S Strip Club Identity, Wayne Coffey
Geography Masters Research Papers
Identities of place develop through a multitude of perceptions. Place myths guide much of this perception. Portland, Oregon’s identity has evolved in particular around a much quoted but unchallenged statistic regarding the volume of nude dancing venues. This paper focuses on the literature specific to both nude dance venues and place identity; Portland’s legal history that contributed to this phenomenon; and some of the cultural and spatial variables pertinent to this issue. Two initiatives, aimed at restructuring the state constitution specifically to deal with nude dance venues and other adult entertainment, are analyzed.

Social Interaction At The Maya Site Of Copan, Honduras: A Least Cost Approach To Configurational Analysis, Heather Richards-Rissetto
Social Interaction At The Maya Site Of Copan, Honduras: A Least Cost Approach To Configurational Analysis, Heather Richards-Rissetto
Department of Anthropology: Faculty Publications
In this article, I employ least cost paths using GIS to measure the relationship between site configuration and social connectivity at the ancient Maya site of Copan, Honduras. I investigate two questions. First, did people of different social classes experience varying degrees of social connectivity? Second, did people living in different parts of the city experience difference degrees of social connectivity? Ultimately, the goal is modify traditional configurational analysis using least cost analysis (LCA) to identify how social hierarchy was embedded in landscapes and how ancient people may have strategically manipulated landscapes to structure social interaction and community organization.
Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley
Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley
Geography and the Environment: Graduate Student Capstones
The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …
Applying Gis Metrics To Determine Degree Of Glacial Modification In Mountainous Landscapes, Carl Delbert Swanson Ii
Applying Gis Metrics To Determine Degree Of Glacial Modification In Mountainous Landscapes, Carl Delbert Swanson Ii
All Master's Theses
The ability to quantitatively assess the degree of glaciation in mountainous areas can be a powerful tool in unraveling the evolution of landscapes, and provide key insights in regions where field research is difficult. Here we determine, test, and apply metrics that assess the relative degree of past glacial modification in mountainous landscapes. Results show that slope results can be used to quantitatively assess the degree to which an area is modified by glaciation. In particular, analysis of basins using slope frequency distribution curves and slope vs. elevation plots capture steeper slopes, flatter valley bottoms, cirques, and arêtes of glaciated …

Transboundary Political Ecology In The Peru-Brazil Borderlands: Mapping Workshops, Geographic Information, And Socio-Environmental Impacts, David S. Salisbury, A. William Flores De Melo, Pedro Tipula Tipula
Geography and the Environment Faculty Publications
Development, resource, and settlement frontiers inspired by national policies and global demand continue to expand into the international boundary lands of Amazonia. National policies promote development and conservation projects on lands already inhabited and managed. Regional governments are increasingly frustrated by the inadequate and outdated geographic information available to solve overlapping claims and improve planning in sensitive border regions. The resulting combination of inappropriate policies, contested resources, and poor geographic information in the borderlands create impacts not only for national, regional, and local landscapes and livelihoods but also foreign relations due to transboundary effects. This article uses a transboundary political …

Como se demuestra en la Figura 1, la Reserva Comunal Purús colindante, sirve como zona de amortiguamiento entre …
Vertical Deformation Along The San Andreas Fault, Garrett Thornton
Vertical Deformation Along The San Andreas Fault, Garrett Thornton
Open Access Theses & Dissertations
There have been numerous M 6+ earthquakes along the San Andreas Fault System (SAFS) (Schwartz et al., 1984) (Figure. 1.1) in the historical past. These rupture events have created millions of dollars worth of damage, and have been responsible for multiple lives lost. An improved understanding of the motions and crustal characteristics along the SAFS can lead to better hazard mitigation (Bakun et al., 2005). Horizontal crustal motions of the SAFS have been widely studied and applied to seismic hazard models (WGCEP, 2007), however vertical motions are not often utilized due to their complicated origin and sometimes large uncertainties. This …
The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz
The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz
Publications and Research
This paper aims to advance two objectives: (1) identify and explore greenhouse gas emissions from urban areas in Asia at the regional level; and (2) explore covariates of urban greenhouse gas emissions. We use the Emissions Database for Global Atmospheric Research estimates for carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride from 14 source activities for the year 2000, which are allocated on a 1/108 global grid. We extract emissions for 3535 urban extents all with populations over 50,000, accounting for approximately 91% of the region’s urban population. We use regression analysis to associate emissions with urban area and growth, …
Mapping And Assessing Urban Impervious Areas Using Multiple Endmember Spectral Mixture Analysis: A Case Study In The City Of Tampa, Florida, Fenqing Weng
USF Tampa Graduate Theses and Dissertations
The advance in remote sensing technology helps people more easily assess urban growth. In this study, the utility of multiple endmember spectral mixture analysis (MESMA) is examined in a sub-pixel analysis of Landsat Thematic Mapper (TM) imagery to map urban physical components in Tampa, FL. The three physical components of urban land cover (LC): impervious surface, vegetation and soil, were compared using the proposed MESMA with a traditional spectral mixture analysis (SMA). MESMA decomposes each pixel to address the heterogeneity of urban LC characteristic by allowing the number and types of endmembers to vary on a per pixel basis. This …
Quasi‐Hidden Markov Model And Its Applications In Cluster Analysis Of Earthquake Catalogs, Zhengxiao Wu
Quasi‐Hidden Markov Model And Its Applications In Cluster Analysis Of Earthquake Catalogs, Zhengxiao Wu
Research Collection School of Economics
We identify a broad class of models, quasi-hidden Markov models (QHMMs), which include hidden Markov models (HMMs) as special cases. Applying the QHMM framework, this paper studies how an earthquake cluster propagates statistically. Two QHMMs are used to describe two different propagating patterns. The “mother-and-kids” model regards the first shock in an earthquake cluster as “mother” and the aftershocks as “kids,” which occur in a neighborhood centered by the mother. In the “domino” model, however, the next aftershock strikes in a neighborhood centered by the most recent previous earthquake in the cluster, and therefore aftershocks act like dominoes. As the …

Spatial Analysis Of Fatal Automobile Crashes In Kentucky, William Nathan Oris
Masters Theses & Specialist Projects
Fatal automobile crashes have claimed the lives of over 33,000 people each year in the United States since 1995. As in any point event, fatal crash events do not occur randomly in time or space. The objectives of this study were to identify spatial patterns and hot spots in FARS (Fatal Analysis Reporting System) fatal crash events based on temporal and demographic characteristics. The methods employed included 1) rate calculation using FARS points and average daily traffic flow; 2) planar kernel density estimation of FARS crash events based on temporal and demographic attributes within the data; and 3) two case …
Measuring Accessibility To Primary Care Physicians In The Nashville Metropolitan Statistical Area, Sami M. Almudaris
Measuring Accessibility To Primary Care Physicians In The Nashville Metropolitan Statistical Area, Sami M. Almudaris
Masters Theses & Specialist Projects
The growing concern for the shortage of primary care physicians (PCPs) prompted a government legislation to designate areas where shortage in the delivery of primary care services occurs. The implemented systems (e.g., HPSA, MUA, and MUP) analyze utilization of health services within confined administrative units and fail to account for spatial interactions that occur across administrative borders. This research examines the spatial accessibility to PCPs and the underlying demographic and socioeconomic settings. With the Nashville Metropolitan Statistical Area (MSA) as a study area, this study utilized data from the U.S. Census 2000 and 2010, as well as the known locations …

Sensitivity Analysis On Mapping Evapotranspiration At High Resolution Using Internal Calibration (Metric), Venkata Naga Ravi Kumar Choragudi
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
Mapping EvapoTranspiration at high Resolution using Internal Calibration (METRIC) is most widely used to quantify evapotranspiration (ET) spatially and temporally. It is essential to inspect the model’s response to errors in various parameters used in the model. Landsat 5 images from May 30 2009, July 1 2009 and a Landsat 7 image from September 27 2009 are used in this study. Fourteen different fields composed of Corn, Soybeans, Alfalfa are randomly chosen for each crop type.
Two kinds of errors are addressed in this study. One, with the errors that are transferred and potentially compensated by calibration (Global error) and …
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Graduate Theses and Dissertations
The impacts of an April 2007 spring freeze event on the productivity of deciduous broadleaf forest were analyzed using geographic information system (GIS) tools. Forest productivity was modeled using the Enhanced Vegetation Index (EVI), as recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor. Measures of spatial autocorrelation were used to quantify the degree of spatial congruence between a map depicting the severity of the freeze event, and maps modeling forest productivity throughout the year. The results show a geographic correlation between the unseasonably low minimum temperatures sustained during the freeze and the unusually low forest productivity that followed. …

Surface Modeling Topsoil Distribution On A Reclaimed Coal-Mine Site At Blackmesa Mine Complex, Kayenta, Arizona, Janine Ferarese
Geography and the Environment: Graduate Student Capstones
A necessary precursor to ensure proper vegetation growth on reclaimed coal-mine areas is even distribution of topsoil. This capstone discusses development of surface models to describe the accurate determination and visualization of the distribution of topsoil. Prediction surfaces from topsoil-depth point samples were created using the surface interpolation methods, Inverse Distance Weighted and Kriging. The validity and accuracy of each method was assessed to determine the best method to evaluate actual topsoil distribution at a coal mining site. The model can be utilized by non- spatially trained personnel working in the mining arena as an aid in assessing how appropriately …

The City of Richmond and the Virginia Department of Transportation proposed to rehabilitate the Gambles Mill Trail connecting the University of Richmond (UR) to the intersection of Huguenot and River Road. Planners envision this trail as a sustainable model for the reduction of nutrient and sediment flow and as a vital path in a city-wide network of bike and pedestrian trails. Meanwhile, UR also proposes to rehabilitate the corridor in their new Master Plan. Nevertheless, until now, no substantive studies exist on the trail or the corridor linking the trail to the south side of the James River through the …
Beyond The Epsilon Band: Polygonal Modeling Of Gradation/Uncertainty In Area-Class Maps, Barry Kronenfeld
Beyond The Epsilon Band: Polygonal Modeling Of Gradation/Uncertainty In Area-Class Maps, Barry Kronenfeld
Faculty Research and Creative Activity
A spatial modeling technique is proposed to represent boundary uncertainty or gradation on area-class maps using a simple polygon tessellation with designated zones of indeterminacy or transition zones. The transition zone can be conceptualized as a dual of the epsilon band, but is more flexible and allows for a wide range of polygonal configurations, including polygons with sinuous boundaries, spurs, three-way transition zones, and null polygons. The model is specified using the medial axis to capture the general shape characteristics of a transition zone. Graph theoretic representation of an extended version of the medial axis captures key junctions in both …

Continuity Of Landsat Obersvations: Short Term Considerations, Michael A. Wulder, Joanne C. White, Jeffrey G. Masek, John Dwyer, David P. Roy
GSCE Faculty Publications
As of writing in mid-2010, both Landsat-5 and -7 continue to function, with sufficient fuel to enable data collection until the launch of the Landsat Data Continuity Mission (LDCM) scheduled for December of 2012. Failure of one or both of Landsat-5 or -7 may result in a lack of Landsat data for a period of time until the 2012 launch. Although the potential risk of a component failure increases the longer the sensor's design life is exceeded, the possible gap in Landsat data acquisition is reduced with each passing day and the risk of Landsat imagery being unavailable diminishes for …

Re-Evaluating Vietnam’S Nghe-Tinh Soviets (1930-1931) Using A Historical Gis: Some Preliminary Observations, David W. Del Testa
Faculty Journal Articles
The Nghe-Tinh Soviets of 1930-1931, a rebellion against colonial authority in north-central and central colonial Vietnam, has received extensive analysis by a variety of commentators and scholars, both Vietnamese and not. Most scholars, Vietnam and internationally, settled on some view of immiseration combined with the presence of pro-communist organizers as the motive forces for the rebellion, but a few have favored questions of political dissatisfaction and local empowerment as underlying motivations for revolt. Until recently, examining the rebellion on a gross scale in order to test either theory has proven difficult, with a surfeit of information but no easy way …

'The Earth Is Crying Out In Pains Of Childbirth': Bauxite Mining And Sustainable Rural Development In The Brazilian Atlantic Forest, Lena R. Connor
Environmental Analysis Program Mellon Student Summer Research Reports
In 2003, residents of the Serra do Brigadeiro Territory, a rural region of Southeastern Brazil in one of the few remaining patches of the Atlantic Forest, learned of a large number of bauxite concessions in their territory given by the federal government to the prominent Companhia Brasileira de Alumínio (CBA), Brazil’s largest aluminum producer. Because the region prides itself on its small-scale agriculture and its lush natural environment, the mining has been the source of much contention in the community. Introduced to the topic by the international conservation non-profit and research center, Iracambi, I spent two months in the territory …
