Mapping Covid-19: How Web-Based Maps Contribute To The Infodemic, Peter Mooney, Levente Juhasz

GIS Center

A proliferation of web-based maps have appeared depicting many different aspects of the spread of the novel coronavirus (SARS-CoV-2). In this commentary, we consider the usage of web-based mapping during the COVID-19 pandemic and argue that web maps have been widely misused for delivering public information on this fast moving, epidemiologically complex, and geographically unbounded process.

A Conceptual Agent-Based Model Of Farming Households’ Vulnerability To Winter Storms, Yiyi Zhang 2020 University of Northern Iowa

A Conceptual Agent-Based Model Of Farming Households’ Vulnerability To Winter Storms, Yiyi Zhang

International Journal of Geospatial and Environmental Research

Vulnerability assessments are implemented to identify regions and groups at risk and factors that need to be addressed to reduce vulnerability. Existing assessments have allowed multidimensional factors to be examined in various settings and adopted complex models to simulate human-environment-weather interactions. However, these models are far less accessible than traditional models due to model abstraction and there has been limited research detailing a formalized way to simulate the interactions between rural households and external changes in response to a specific extreme weather event. To supplement applied efforts in vulnerability assessments and address the challenge in communicating agent-based models, this study ...

Exploring The Archaeological And Geographical Past Of Fort Spokane: A Proposal, Hope Sands, Brian Buchanan

2020 Symposium Posters

This poster presents the project design of a student-led research project addressing the history and archaeological significance of Fort Spokane, a 19th century military fortification along Lake Roosevelt and south of Coolie Dam, Washington. Portions of the Fort were previously excavated, however, since then not much has been done in terms of archaeological research and key questions remain on the development and landscape history of the fort (Riser and DePuydt 2012). New methodologies and theoretical approaches make this an ideal time to reexamine the fort, and to address key questions on how the fort developed, why it was located where ...


Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou 2020 West Virginia University

Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou

International Journal of Geospatial and Environmental Research

This paper presents an exploratory spatial data analysis (ESDA) of road traffic crashes at different severity levels in West Virginia (WV). Although ESDA can support transportation safety decision-making by helping planners understand and summarize crash data, it is underutilized in practice. This paper describes the application of five representative easy-to-use method to identify crash patterns and high crash-risk counties in WV. Analysis of crash data from 2010 to 2015 indicated that traffic crashes in WV were not spatially correlated. However, crash severities were found to be positively correlated.

In the future, the city of Knoxville, Tennessee will be impacted by climate warming due to anthropogenic climate change. Yet, the ecosystem services provided by urban tree canopy in Knoxville’s urban forest can help mitigate the effects of climate warming. In addition to improving air quality, regulating water flow, and reducing noise pollution, Knoxville’s urban forest serves as a carbon sink and sequesters carbon dioxide on an annual basis. Utilizing methods for calculating carbon sequestration by trees in urban and suburban settings developed by the U.S. Energy Information Administration, the sequestration potential and its uncertainty is calculated ...


The Invasion Of The Southern Pine Bark Beetle, Matthew Shaughnessy 2020 SUNY Cortland

The Invasion Of The Southern Pine Bark Beetle, Matthew Shaughnessy

Transformations: Presentation Slides

The Southern Pine Bark Beetle is a pest that is native to the south eastern United States. Historically the population has been held to southern parts of the nation due to the harsher cold weather in the north. During the last twenty years there has been an increase in average annual temperatures on the east coast. This has allowed the species to move northward and afflict unprotected softwoods at a high rate. The objective of this project was to observe the movement of the Southern Pine Bark Beetles between 2012 and a population estimate for 2027 made by the USDA ...

Modeling Movement: A Machine-Learning Approach To Track Migration Routes After Displacement, Ethan Harrison 2020 William & Mary

Modeling Movement: A Machine-Learning Approach To Track Migration Routes After Displacement, Ethan Harrison

Undergraduate Honors Theses

Over the past decade, the number of individuals internally displaced by conflict (IDPs) has reached unprecedented levels. Humanitarian actors and first-responders face persistent information gaps in meeting the needs of these populations. Specifically, they face challenges in understanding where and how IDPs move after they are displaced, which is necessary to locate them in conflict-affected situations and provide them with life-saving assistance. In this paper, I propose a framework, using established machine-learning methods, to forecast the migration routes of these displaced populations (Chapter 1). In a case study of displacement in Yemen, my models predict 80% of IDPs' migration routes ...


Learning About Learning With Deep Learning: Satellite Estimates Of School Test Scores, Heather M. Baier 2020 William & Mary

Learning About Learning With Deep Learning: Satellite Estimates Of School Test Scores, Heather M. Baier

Undergraduate Honors Theses

Convolutional neural networks are deep-learning models commonly applied when analyzing imagery. Convolutional neural networks and satellite imagery have shown potential for the global estimation of key factors driving socioeconomic ability to adapt to global change. Unlike more traditional approaches to data collection, such as surveys, approaches based on satellite data are low cost, timely, and allow replication by a wide range of parties. We illustrate the potential of this approach with a case study estimating school test scores based solely on publicly available imagery in both the Philippines (2010, 2014) and Brazil (2016), with predictive accuracy across years and regions ...

280— Exploring The Geographic Distribution Of Childbed Fever Deaths In Mid-19th Century Rochester, Ny, Meaghan Parks

GREAT Day

Childbed fever, formally called puerperal fever or puerperal septicemia, is an infection typically contracted by women after childbirth. Historically, childbed fever was a serious threat to maternal health. Childbed fever is caused by exposure of open wounds or abrasions, which are common after giving birth, to group A and B Streptococcal bacteria. Ignaz Semmelweis discovered that hand washing using a chlorinated solution reduced cases of childbed fever in 1847. This project reviews the instances of death from childbed fever in Rochester, New York from 1837-1860 and later from 1907-1919 and attempts to determine which areas of the city had the ...

216— Using Rochester’S Family Public Housing In The “Crescent Of Poverty” As A Catalyst For A Solar Initiative, Christopher Miller

GREAT Day

Both the climate crisis and poverty rates in US cities have increased rapidly, with few solutions. This research examines the relative solar potential in public housing developments in Rochester, NY, specifically in the area of concentrated poverty called the “Crescent of Poverty.” Also examined are societal benefits that an inclusive solar/sustainability movement provides for Rochester. Rochester is a mid-sized, diversely populated city with an overall poverty rate >30% and a childhood poverty rate >50% (Murphy, 2018). These alarming rates have contributed to the creation of the “Crescent of Poverty”, where the majority of family public housing developments are located ...
