From The Abacus To Big Data: The Evolution Of Data-Driven Planning In The U.S. And Where The Field Will Be Headed, Keuntae Kim

Journal of Comparative Urban Law and Policy

The nature of planning involves a set of decision-making processes to fulfill people’s needs and expectations of where they live, work, and play. Dealing with the nature of planning—complexity, uncertainty, and disagreement—requires specific tools to explore various aspects of the built environment as a whole. Various types of data have been extracted, transformed, and loaded to describe the past and current conditions of the built environment, and planners have developed and applied data-driven planning tools to explore the knowns and unknowns of the urban futures and transform them into a set of actions based on the goals with consensus. This …

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

School of Natural Resources: Dissertations, Theses, and Student Research

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …

Toward Global Localization Of Unmanned Aircraft Systems Using Overhead Image Registration With Deep Learning Convolutional Neural Networks, Rachel Linck

Graduate Theses and Dissertations

Global localization, in which an unmanned aircraft system (UAS) estimates its unknown current location without access to its take-off location or other locational data from its flight path, is a challenging problem. This research brings together aspects from the remote sensing, geoinformatics, and machine learning disciplines by framing the global localization problem as a geospatial image registration problem in which overhead aerial and satellite imagery serve as a proxy for UAS imagery. A literature review is conducted covering the use of deep learning convolutional neural networks (DLCNN) with global localization and other related geospatial imagery applications. Differences between geospatial imagery …

Red Wolf Reintroduction: Land Ownership And Protection Status Analysis, Anna Frisbie

Environmental Studies Senior Seminar Projects

Red wolves (Canis rufus) are critically endangered, and currently the only wild population exists in northeast NC (“Red Wolf,” FWS, n.d.). Here, I use geospatial analysis to investigate the potential for another wild population to establish in the Delmarva Peninsula. I consider land ownership and protection status because these factors influence local public support (Nie, 2001; Naughton-Treves et al., 2003; Berger-Tal et al., 2020), as well as reintroduction success (Carroll et al., 2003; Wolf & Ripple, 2018). I compare the ownership and protection status of land in the Delmarva Peninsula to that in the Albemarle Peninsula, where the red wolf …

Possible Location For Us Embassy In Copenhagen, Denmark, Danny Jang

Symposium of Student Scholars

The purpose of this research is for students to experience using GIS in a professional setting for a public organization. Copenhagen, Denmark hosts numerous embassies for other countries including the USA which was established nearly a century ago! After going through a couple of public opinions left by the locals (Google review), it would be nice if another location was established to assist both USA and Denmark’s bureaucratic needs. The population has surged compared to the numbers from when the building was established, which also changed the geospatial environment that was established when the building was opened. This research will …

Social Vulnerability, Diabetes, And Obesity In Georgia, Danny Jang

Symposium of Student Scholars

This project examines factors of health geography and population geography by examining the spatial correlation between diabetes and obesity prevalence among the population of Georgia. Diabetes and obesity are closely linked together, however, they are still far apart in various aspects which can be from personal to environmental impacts like geographical locations. This research attempts to investigate diabetes and obesity prevalence by examining the SVI of given counties of a state. This project uses data from the Atlanta-based Centers for Disease Control and Prevention (CDC) and Opendata (which can be found on ESRI). Future studies can examine these health factors …

A Street-Based Simulation Approach To Evaluating Crime Theories And Deterrence Efficacy In Baton Rouge, Louisiana, Shaun Edward Williams

LSU Doctoral Dissertations

Criminology of place and deterrence strategy evaluations share separate yet similar paths towards incorporating microgeographic units of analysis within deterrence strategies. These transitions have been underway since Weisburd’s 2015 criminology of place work and Kennedy’s 1997 Ceasefire publication for deterrence strategy evaluation. Rather than purely theoretical or practical challenges serving as agents of change, scale appropriateness can arguably be pinpointed as the foundation for change in both areas. Microplace offers improved insight into the study of crime and place dominated by areal designs. This status quo has hampered evaluation but has not slowed the flow of resources to support strategy …

The Role Of Physical Geographic Features In Video Games, Dexter Ferguson

Theses

This thesis examines how physical geographic features affect individuals when interacting with video game environments. There are very few studies on the geography of video games. I aim to bridge the gap between game studies and geography, a naturally occurring link. The observation of elements such as the geography of an area is critical when exploring an individual’s perception of a video game environment. Individuals interact with the geography of their location on a day-to-day basis, whether it be physical or human geography; how they can relate a video game’s geography to the real world dramatically affects their immersion. An …

The Spatial Organization Of Pre-Colonial African Kingdoms: The Empires Of Ethiopia & Mali, Victoria O. Alapo

Department of Geography: Dissertations, Theses, and Student Research

Pre-Colonial kingdoms in Sub-Saharan Africa were many, and were organized in unique ways. The old Empires of Ethiopia and Mali were selected for this research because of their antiquity and for their contrasts: Ethiopia was an official Christian Empire for about two millennia, while Mali was the quintessential Sub-Saharan Islamic kingdom. Also, both empires possessed documentation written by traditional Africans, in the form of ancient indigenous manuscripts, which predate the colonial period (i.e., the coming of Europeans) by several centuries. In addition, the research analyzes work that has been done by historians and other academics, and incorporates the reports of …

Spatial Downscaling Of Goes-R Land Surface Temperature Over Urban Regions: A Case Study For New York City, Abdou Bah, Hamidreza Norouzi, Satya Prakash, Reginald Blake, Reza Khanbilvardi, Cynthia Rosenzweig

Publications and Research

The surface urban heat island (SUHI) effect is among the major environmental issues encountered in urban regions. To better predict the dynamics of the SUHI and its impacts on extreme heat events, an accurate characterization of the surface energy balance in urban regions is needed. However, the ability to improve understanding of the surface energy balance is limited by the heterogeneity of surfaces in urban areas. This study aims to enhance the understanding of the urban surface energy budget through an innovation in the use of land surface temperature (LST) observations from remote sensing satellites. A LST database with 5–min …

Unraveling The Geographies Of The U.S. Public Education System: An Analysis Of Scale, Segregation, And Hegemony, Olivia Ildefonso

Dissertations, Theses, and Capstone Projects

Other than one or two studies that focus on specific state-wide systems of public education, there has been no accounting for how the U.S. public education system came about in relation to space and scale. My dissertation research seeks to fill in this gap. Through focusing on the development of public education in the North and the South, I provide a foundation for understanding the grounded and contested processes of scale production that largely determined the U.S. public education system’s design and function.

In each of the seven chapters, I detail how fights over the structure and purpose of public …

Detecting And Visualizing Observation Hot-Spots In Massive Volunteer-Contributed Geographic Data Across Spatial Scales Using Gpu-Accelerated Kernel Density Estimation, Guiming Zhang

Geography and the Environment: Faculty Scholarship

Volunteer-contributed geographic data (VGI) is an important source of geospatial big data that support research and applications. A major concern on VGI data quality is that the underlying observation processes are inherently biased. Detecting observation hot-spots thus helps better understand the bias. Enabled by the parallel kernel density estimation (KDE) computational tool that can run on multiple GPUs (graphics processing units), this study conducted point pattern analyses on tens of millions of iNaturalist observations to detect and visualize volunteers’ observation hot-spots across spatial scales. It was achieved by setting varying KDE bandwidths in accordance with the spatial scales at which …
