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 …


Improvements In Multi-Tool Surveying Efficiency For Archaeological Geophysics, Caitlyn Marie Williams Dec 2011

Improvements In Multi-Tool Surveying Efficiency For Archaeological Geophysics, Caitlyn Marie Williams

Masters Theses

Conventional archaeological excavation methods are, by nature, extremely invasive and result in study areas being irrevocably altered for the sake of research. For this reason, near-surface geophysical techniques have been incorporated into archaeological investigations to aid in determining the locations of buried features with minimal damage to the site. The objective of this research was to perform a geophysical survey at an archaeological site on the Akrotiri Peninsula in Cyprus to locate evidence of a Roman naval base and to develop an improved data management workflow that will improve the usefulness of geophysical data to archaeologists.

Measuring Accessibility To Primary Care Physicians In The Nashville Metropolitan Statistical Area, Sami M. Almudaris Dec 2011

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 …

Automatic High-Fidelity 3d Road Network Modeling, Jie Wang Jul 2011

Automatic High-Fidelity 3d Road Network Modeling, Jie Wang

Computational Modeling & Simulation Engineering Theses & Dissertations

Many computer applications such as racing games and driving simulations frequently make use of 3D high-fidelity road network models for a variety of purposes. However, there are very few existing methods for automatic generation of 3D realistic road networks, especially for those in the real world. On the other hand, vast road network GIS data have been collected in the past and used by a wide range of applications, such as navigation and evaluation. A method that can automatically produce 3D high-fidelity road network models from 2D real road GIS data will significantly reduce both the labor and time needed …

Geologic Constraints On Rain-Fed Qocha Reservoir Agricultural Infrastructure, Northern Lake Titicaca Basin, Peru, Nathan M. Craig, Mark Aldenderfer, Paul Baker, Catherine Rigsby, :Luis Flores Blanco Jan 2011

Geologic Constraints On Rain-Fed Qocha Reservoir Agricultural Infrastructure, Northern Lake Titicaca Basin, Peru, Nathan M. Craig, Mark Aldenderfer, Paul Baker, Catherine Rigsby, :Luis Flores Blanco

Nathan M Craig

This paper reports new data on qocha ponds from the Rio PucaraeAzángaro interfluvial zone, northern Lake Titicaca Basin, Peru. Qocha are a little known form of Andean agriculture that developed around 800e500 B.C. and remain in use today. Prior estimates suggested that in the study area, there were more than 25,000 qocha. While most Andean sunken beds are excavated to reach groundwater, qocha are rain- fed ponds. How these rain-fed ponds functioned has been an open question, but one that is answered in part by research presented in this paper.We suggest that a thick impermeable stratum of clay that was …


Ground Truthing Of Remotely Identified Fortifications On The Central Coast Of Perú, Margaret Brown Vega, Nathan M. Craig, Gerbert Asencios Lindo Jan 2011

Ground Truthing Of Remotely Identified Fortifications On The Central Coast Of Perú, Margaret Brown Vega, Nathan M. Craig, Gerbert Asencios Lindo

Nathan M Craig

Remote imagery, including freely available satellite images viewed in Google Earth_ and historic aerial photographs, was used to identify anomalies in a 25,000 km2 macroregion encompassing 13 river valleys along the Peruvian coast. These anomalies, located atop hills and mountains, were hypothesized prehispanic fortifications. A sample of remotely identified anomalies was ground truthed in the Huaura and Fortaleza Valleys on the Central Coast of Perú. 140 positive anomalies were documented and assessed using a simple defensibility index. Our results significantly increase the number of fortifications identified in both valleys. We demonstrate the efficacy of this method for locating fortifications in …


Advancing Theory?: Landscape Archaeology And Geographical Information Systems, Di Hu Jan 2011

Advancing Theory?: Landscape Archaeology And Geographical Information Systems, Di Hu

Di Hu

This paper will focus on how Geographical Information Systems (GIS) have been applied in Landscape Archaeology from the late 1980s to the present. GIS, a tool for organising and analysing spatial information, has exploded in popularity, but we still lack a systematic overview of how it has contributed to archaeological theory, specifically Landscape Archaeology. This paper will examine whether and how GIS has advanced archaeological theory through a historical review of its application in archaeology.


Mapping Time, Edward L. Ayers Jan 2011

Mapping Time, Edward L. Ayers

History Faculty Publications

Our tools for dealing with terrestrial space are well-developed and becoming more refined and ubiquitous every day. GIS has long established its dominion, Google permits us to range over the world and down to our very rooftops, and cars and cell phones locate us in space at every moment. It is hardly surprising that geography and mapping suddenly seem important in new ways. Historians have always loved maps and have long felt a kinship with geographers. The very first atlases, compiled six hundred years ago, were historical atlases. But space and time remain uncomfortable—if ever-present and ever-active—companions in the human …


An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez Jan 2011

An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez

Open Access Theses & Dissertations

Crustal rupture structures reactivated in the course of the tectonic history of northern Mexico are the surface expressions of planes of weakness, in the form of simple or composite rectilinear features or slightly curved, defined as lineaments. Unless otherwise defined as strike-slip faults, lineaments are part of parallel and sub-parallel oblique convergent or oblique divergent tectonic zones cross cutting the Sierra Madre Occidental and northern Mexico, in a NW trend. These shear zones are the response to the oblique subduction of the Farallon plate beneath North America.

Kinematic analysis of five selected sites in northern Mexico, three basins and two …


Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein Jan 2011

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

Park Access And Distributional Inequities In Pinellas County, Florida, Kyle Ray Hirvela Jan 2011

Park Access And Distributional Inequities In Pinellas County, Florida, Kyle Ray Hirvela

USF Tampa Graduate Theses and Dissertations

Although environmental justice research has traditionally focused on environmental disamenities and health hazards, recent studies have begun to examine social inequities in the distribution of urban amenities such as street trees and parks that provide several direct and indirect health benefits to local residents. This thesis adds to this knowledge by evaluating distributional inequities in both distribution and access to parks in Pinellas County, the most densely populated and one of the most racially segregated counties in Florida. An important objective was to determine if neighborhoods with lower levels of park access are more likely to contain a significantly higher …


Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green Jan 2011

Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose for studying exurbanization is to evaluate the spatial spread of metropolitan areas into their immediate hinterlands through remote sensing satellite imagery. This includes addressing scholar's inability to define exurbia, along with plausible reasons people move into exurbia. In addition, determination will include consideration on the possibility that exurbia has become an extension of America's growing and increasingly independent suburbia or; recognize that exurbia exists, but within various geographic locations. In return to the former, an analytical approach was taken to investigate scholar's inability to provide a definition to this phenomena; as well as inconsistent results on the push …


Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal Jan 2011

Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal

Legacy Theses & Dissertations (2009 - 2024)

This thesis presents a brief overview of quantitative spatial analysis in archaeology with a discussion of the theoretical and methodological issues involved, and describes a set of methods for using Geographic Information System (GIS) software and spatial statistics for the assessment of archaeological resources. GIS has become a nearly ubiquitous and indispensable tool in many fields of resource management including archaeology. It is, however, applied by archaeologists most frequently for basic cartographic representations, large-scale regional analyses, or resource management data warehousing. Such applications underutilize the scale-independence of GIS, which is equally potent for intra-project data assessment. This thesis describes a …
