Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles

Masters Theses & Specialist Projects

Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …

Assessing Uncertainty In Volunteered Geographic Information For Emergency Response, Michael Camponovo

Geography ETDs

This research project examines data produced by volunteers through the Ushahidi web platform in response to the earthquake that struck Haiti in January 2010. Volunteers translated messages submitted by victims in Haiti, categorized each message based on its content, and georeferenced each message on a dynamic web based map. When categorizing the data, volunteers were able to assign up to 8 main and 42 subcategories to each message. Initial inspection of the attribute data produced by the volunteers indicated a strong discrepancy between the contents of the messages submitted by the victims and the corresponding attributes assigned to those messages …

Restraurant Regions : An Ecological Community Based Model Of Restaurant Chain Distribution In The United States, Stephen Griego

Geography ETDs

The scope of this paper is an exercise in regional identification within the geography of the United States. This paper applied a hierarchical clustering methodology to analyze the distribution of restaurants in the landscape. The clustering model utilized in this study is commonly used in analysis of ecological communities. Each restaurant chain was treated as an individual biological species, and the clustering software analyzed it as such. The individual restaurant chain locations were treated as individual samples in the environment. Wards (1963) algorithm was used to group the individual restaurant chain locations into related clusters using simple correlation as the …

Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin

Doctoral

The increasing availability of abundant geographically referenced information in the Geospatial Web provides a variety of opportunities for developing value-added LBS applications. However, large data volumes of the Geospatial Web and small mobile device displays impose a data visualization problem, as the amount of searchable information overwhelms the display when too many query results are returned. Excessive returned results clutter the mobile display, making it harder for users to prioritize information and causes confusion and usability problems. Mobile Spatial Interaction (MSI) research into this “information overload” problem is ongoing where map personalization and other semantic based filtering mechanisms are essential …

This fort was an 18th century French trading post in the St. Joseph River valley located in southwestern Michigan and northwestern Indiana. This study expands our current understanding of the change and continuity of the Euro- American and Native American settlement patterns in the valley during the periods immediately prior to, during, and after the abandonment of Fort St. Joseph through the use of geographic information systems (GIS) and statistical analyses.

Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner

Masters Theses

Three separate storage technologies able to serve gridded data were selected for comparison of performance in terms of providing speed and expandability to a crop disease forecasting system. The three storage technologies chosen were PostgreSQL (a relational database management system), MongoDB (NoSQL system), and netCDF files. Speed tests were performed for each by running two different crop disease risk forecasting models requiring data of different spatiotemporal resolutions. Multiple trials were done using different storage hardware. Systems were then qualitatively compared for expandability by noting the process involved in adding successive crop disease forecasting models.

It was found that due to …

Gis-Based Flood Analysis For Adequate Flood Mitigation In An Unplanned Urban Area; The Case Of Pikine Dagoudane In Dakar County, Senegal, Sokhna Helene Diop

Masters Theses

Since 1989, Pikine Dagoudane, in the suburbs of Dakar City has faced several flooding events, resulting in economic loss, environmental degradation and severe disturbance of the social life of the residents. The mitigation programs implemented have not appeared to provide any relief since 2000. Review of the existing literature on the crisis has revealed that the general scale of the studies, and the insufficient attention to some of the major factors could be accounted for such little efficiency. This thesis applies a different approach, based on a small area and focusing mainly on topographic characteristics, to provide a better understanding …

Tax Increment Financing (TIF) is one of the most widely used economic development tools in the nation. In 2008, Charleston, South Carolina, designated the Cooper River Bridge neighborhood (CRBN) as its fourth TIF district. The planning process is now underway, and many large redevelopment projects have already started construction. Private investors will receive funding to develop vacant lots and revitalize dilapidated properties, and the City will benefit economically from new property taxes added to the revenue roll. City officials have anticipated the economic change this TIF district will provide, but have they properly anticipated the changes that will occur to …

Integrating Spatial Modeling Into Recreational Planning In Parks And Protected Areas, John Beeco

All Dissertations

Understanding the utility of space in natural area resources is of growing importance as recreation in these areas increases and availability of land remains stagnant. Space utility is of particular importance to multiple use forests which may have multiple recreation demands, minimum acceptable levels of biophysical impacts, sensitive ecological areas, and/or timber harvesting and mineral extraction strategies for the generation of revenue. In order to holistically consider space and protected area management, three factors must be better understood: a) methods and spatial analysis tools that can help with managerial and planning decisions, b) how space affects the relationship between use …

Site Location Modeling And Prehistoric Rock Shelter Selection On The Upper Cumberland Plateau Of Tennessee, Lucinda M. Langston

Electronic Theses and Dissertations

Using data collected from 2 archaeological surveys of the Upper Cumberland Plateau (UCP), Pogue Creek Gorge and East Obey, a site location model was developed for prehistoric rock shelter occupation in the region. Further, the UCP model was used to explore factors related to differential site selection of rock shelters. Different from traditional approaches such as those that use (aspatial) logistic regression, the UCP model was developed using spatial logistic regression. However, models were also generated using other regression-based approaches in an effort to demonstrate the need for a spatial approach to archaeological site location modeling. Based on the UCP …

Masters Theses

The State of Michigan offers a unique retail environment that offers a diverse arena for firms to interact and compete in. The state has many cities of different size and a multitude of retail chains that operate within them. Over the past two decades this competition has become even stiffer with the rapid growth of big box retailers. In spite of this general notion there are often the less known stories of small retailers that have been able to compete and survive big box retailing. This research aims to assess how a smaller retail chain, GameStop in this case, is …

An Empirical Assessment Of The Performance And Competitive Effects Of Los Angeles County Charter Schools, Sam Trachtman

Undergraduate Economic Review

This paper evaluates the performance of charter elementary schools in Los Angeles County in three ways. First, I compare charter school performance to public school performance, controlling for a number of key characteristics. Second, I study the characteristics that appear to influence charter school success as compared to public school success. Third, I study the “competitive effect” of charter schools, examining how geographical proximity to charter schools affects the performance of traditional public schools. I find evidence that, ceteris paribus, traditional public schools score higher than charter schools, except in majority African American schools. Further, I find that the opening …

Beijing’S Water Crisis: A Historical Analysis Of Beijing’S Waterways Using Geographic Information Systems, Rebecca Tisherman

Environmental Studies Honors Papers

Beijing has a complex system of waterways inside the city of 20 million people, while the rivers just outside of the city run dry most of the year. Geographic Information Systems was used to analyze the historical changes of the waterways, geo-cover, precipitation, and other factors that have affected the water supply to the city. The manmade canals in the city expanded with urbanization until 1983 when there were canals in every corner of the city. The water became too polluted for human use, so canals were slowly converted to culverts. Groundwater was depleted over time as well, so the …

A Study Of Habitat Selection By Blanding's Turtles (Emydoidea Blandingii) In Dutchess County, New York, Shannon Rauch

Legacy Theses & Dissertations (2009 - 2024)

The Blanding's turtle (Emydoidea blandingii) is a New York State-listed threatened species with several disjunct populations located throughout the state. Blanding's turtles require a variety of habitat types including ponds, wetlands, vernal pools, and the surrounding uplands. Preserving these habitat complexes is necessary to ensure the persistence of Blanding's turtle populations, but this is becoming increasingly challenging in some locations due to significant development pressure. Key components of habitat protection are identifying preferred habitat types and gaining a better understanding of the variables that influence habitat selection. Previous landscape-level studies of turtles have found that land cover type, wetland type, …

Modeling Bedrock Mining Hotspots Within The Ouachita National Forest, Arkansas, Stephanie H. Mehlhope

Theses and Dissertations--Geography

This study, concentrating on the Ouachita Mountain Range in western-central Arkansas, extends prior work on treethrows and their influence on soil development in the region by supplying a method of determining hotspots of bedrock mining by treethrow. Binary logistic regression analysis was employed to determine the abiotic and biotic factors that are highly correlated with the rate of bedrock detachment found in uprooted rootwads from three study sites within the Ouachita National Forest. The produced logistic regression models suggest topographic factors, tree specific characteristics, as well as the local geology and soil characteristics all have a significant effect upon the …

Re-Placing Sprawl: Mapping Place In An American Suburb, Ryan M. Cooper

Theses and Dissertations--Geography

In the post-World War II era land development in the United States has largely been focused on the expansion away from urban centers and out into the surrounding suburbs. While the development of suburbs began with utopian ideals of spiritual wholeness, their actual manifestation on the American landscape has been subject to harsh critiques about their long-term economic and environmental feasibility, fostering of social alienation, and general placelessness. In this thesis I address the criticism of suburbs as placeless, asking ―What are the particular practices of place-making in North American suburbs?‖ Examining interviews, cognitive map surveys, participant observation, archival materials, …

Coastal Inundation Due To Sea Level Rise And Extreme Sea State And Its Potential Impacts: Çukurova Delta Case, Özlem Si̇mav, Dursun Zafer Şeker, Cem Gazi̇oğlu

Turkish Journal of Earth Sciences

With the rising sea level becoming a more pressing issue to coastal areas, a comprehensive analysis has been conducted to assess the vulnerability of the Çukurova Delta under the projected inundation by the end of the century. The level of inundation was estimated from a multimission satellite altimetry sea level anomaly and significant wave height data between September 1992 and February 2012. Superposed to the clear annual oscillation with 6.2 cm amplitude peaking around the beginning of October, the mean sea level signal exhibits a positive trend of 3.4 ± 0.1 mm/year over the altimetric data period. The extreme wave …
