The Billion Object Platform (Bop): A System To Lower Barriers To Support Big, Streaming, Spatio-Temporal Data Sources, Devika Kakkar, Ben Lewis, David Smiley, Ariel Nunez Sep 2017

The Billion Object Platform (Bop): A System To Lower Barriers To Support Big, Streaming, Spatio-Temporal Data Sources, Devika Kakkar, Ben Lewis, David Smiley, Ariel Nunez

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

With funding from the Sloan Foundation and Harvard Dataverse, the Harvard Center for Geographic Analysis (CGA) has developed a big spatio-temporal data visualization platform called the Billion Object Platform or "BOP". The goal of the project is to lower barriers for scholars who wish to access large, streaming, spatio-temporal datasets. Since once archived, streaming data gets big fast, and since most GIS systems don't support interactive visualization of millions of objects, a new platform was needed. The BOP is loaded with the latest billion geo-tweets and is fed a real-time stream of about 1 million tweets per day. The CGA …


Spatial Analysis Of Tornado Warning System Understanding And Relationship With Tornado Occurrence, Chesnea A. Skeen Jun 2017

Spatial Analysis Of Tornado Warning System Understanding And Relationship With Tornado Occurrence, Chesnea A. Skeen

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Tornadoes present a significant threat to life and property. The National Weather Service watch and warning system warns the public of tornadoes. If these warnings are not heeded by the public, the potential fatalities and destruction of property cannot be minimized. Thus, to prevent further loss of life and property, it is necessary to understand how the public understands the watch and warning system, as well as how they react. This paper aims to understand the correlation between understanding of watches and warnings and the occurrence of tornadoes, as well as how understanding varies spatially. Survey data were collected from …


Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets Jun 2017

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …


Snow And Non-Snow Events Based Winter Traffic Crash Pattern Analysis And Developing Lake Effect Snow Induced Crash Count Prediction Model, Bandhan Dutta Ayon Jun 2017

Snow And Non-Snow Events Based Winter Traffic Crash Pattern Analysis And Developing Lake Effect Snow Induced Crash Count Prediction Model, Bandhan Dutta Ayon

Masters Theses

This study aims to (i) find the spatial-temporal traffic crash pattern and (ii) develop a statistical model for predicting LES induced traffic crash counts. Three southwest Michigan counties: Allegan, Kalamazoo and Calhoun are selected to conduct this study. Snow and non-snow event based comparative analysis are conducted using Getis-Ord Gi* statistic to identify high density crash cluster locations in the study area. While several new and oscillating hot spots are detected in Allegan during snow, no hot spot is detected during non-snow events based analysis. In Kalamazoo, traffic crashes do not exhibit much difference in spatial-temporal trend during snow or …

Optimizing Stadium Evacuation By Integrating Geo-Computation And Affordance Theory, Joslyn Jane Zale May 2017

Optimizing Stadium Evacuation By Integrating Geo-Computation And Affordance Theory, Joslyn Jane Zale

Dissertations

The purpose of this project was to optimize football stadium evacuation time by integrating geo-computation with affordance theory from perceptual psychology to account for evacuee characteristics: age, gender, physical fitness, alcohol consumption, and prior experience attending football games at The University of Southern Mississippi (USM), evacuating from large, outdoor public places, and with hazard events.

According to the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act, football stadiums are part of the country’s critical infrastructure warranting special government protection. Evacuation modeling was identified as an important component of game day emergency …


Mapping Community Space And Place In Mto Wa Mbu, Tanzania Through Surveys And Gis, Jessica Craigg Apr 2017

Mapping Community Space And Place In Mto Wa Mbu, Tanzania Through Surveys And Gis, Jessica Craigg

Georgia College Student Research Events

Cities throughout the African continent have been developing at an unprecedented pace, many of them due to the influence of the tourism industry. This is particularly true in Tanzania, a country famous for its national parks and their draw to tourists who help provide money for development. However, the only way to get the whole story on how to spend this money is through the experiences and needs of the people themselves. This study focuses on a small town in northeastern Tanzania, Mto wa Mbu, situated near Lake Manyara National Park, and its people’s perceptions of the park and community. …


Terror And Territory: A Spatio-Temporal Analysis Of Isil, Robert Riley Strider Jan 2017

Terror And Territory: A Spatio-Temporal Analysis Of Isil, Robert Riley Strider

Theses, Dissertations and Capstones

The Islamic State of Iraq and the Levant (ISIL), alternatively the Islamic State of Iraq and Syria (ISIS), is one of many non-state organizations that resulted from the extensive foreign intervention in the Middle East leading up to current conflicts there. Like the wider network that it used to be part of, ISIL is considered to be a great threat to modern first world countries. Using data from the Global Terrorism Database (GTD), this paper analyzed the relationship between the amount of territory ISIL held from June 2014 to December 2015 and the attacks it carried out in that time, …


Participatory Web Gis Design – A Sustainable Recreation Decision Support System For Missoula County, Nathanael R. Wold Jan 2017

Participatory Web Gis Design – A Sustainable Recreation Decision Support System For Missoula County, Nathanael R. Wold

Graduate Student Theses, Dissertations, & Professional Papers

Sustainable recreation ensures that local communities benefit from the effects of recreation. A recreation decision support system (RDSS) is a common way for people to gather information about an area they are about to visit. This research explores: 1) how well can local representatives’ knowledge concerning appropriate recreation behaviors be incorporated into a WebGIS that will serve as a RDSS, 2) what layers, activities, and information do participants want to include in a RDSS, and 3) how well does the ArcGIS Online perform in incorporating representatives’ knowledge of areas of significance for a RDSS?

Recreationalists in Missoula County, Montana, have …


Using Geospatial Analysis For High School Environmental Science Education: A Case Study Of The Jane Goodall Institute's Community-Centered Conservation Approach, Madison G. Vorva Jan 2017

Using Geospatial Analysis For High School Environmental Science Education: A Case Study Of The Jane Goodall Institute's Community-Centered Conservation Approach, Madison G. Vorva

Pomona Senior Theses

Given my experiences as a young conservation advocate, I saw a need to teach students the importance of interconnectedness, cultural awareness and systems-thinking skills through a spatial lens. I believe these skills are required for holistic, equitable and sustainable conservation decision-making in local and international contexts. This thesis uses geospatial tools to teach conservation ecology vocabulary and concepts from high school environmental science curriculum in two online resources. The purpose of my lesson plan is to show students how conservationists address complex conservation and land-use challenges using the Jane Goodall Institute’s community-centered conservation approach as a case-study. My hope is …
