Comparing Individual Perceptions Of Food Desert With Quantitative Measures In Omaha, Nebraska., Hector N. Samani, Bradley Bereitschaft Mar 2020

Comparing Individual Perceptions Of Food Desert With Quantitative Measures In Omaha, Nebraska., Hector N. Samani, Bradley Bereitschaft

UNO Student Research and Creative Activity Fair

Food deserts have been linked to an increase in chronic diseases such as obesity and diabetes, due to lower access to affordable and healthy foods. The United States Department of Agriculture (USDA) outlines various methods and variables for defining food deserts, in attempts to standardize what constitutes a food desert or their characteristics. The USDA identifies the state of Nebraska as having both rural and urban food deserts, with an increase of food insecurity from 1.1% – 3.0% between 2007 and 2012 and warns of further increase of food deserts and its impact if measures are not taken. However, there …


Assessing Boreal Peat Fire Severity And Vulnerability Of Peatlands To Early Season Wildland Fire, Laura Bourgeau-Chavez, Sarah L. Grelik, Michael Billmire, Liza K. Jenkins, Eric S. Kasischke, Merritt R. Turetsky Feb 2020

Assessing Boreal Peat Fire Severity And Vulnerability Of Peatlands To Early Season Wildland Fire, Laura Bourgeau-Chavez, Sarah L. Grelik, Michael Billmire, Liza K. Jenkins, Eric S. Kasischke, Merritt R. Turetsky

Michigan Tech Publications, Part 1

Globally peatlands store large amounts of carbon belowground with 80% distributed in boreal regions of the northern hemisphere. Climate warming and drying of the boreal region has been documented as affecting fire regimes, with increased fire frequency, severity and extent. While much research is dedicated to assessing changes in boreal uplands, few research efforts are focused on the vulnerability of boreal peatlands to wildfire. In this case study, an integration of field data collection, land cover mapping of peatland types and Landsat-based fire severity mapping was conducted for four early season (May to mid-June) wildfires where peatlands are abundant in …


Urban Heat In Tropical Kuala Lumpur: Microclimate, Outdoor Thermal Comfort And Mitigation By Land-Cover Modification, Chng Saun Fong Feb 2020

Urban Heat In Tropical Kuala Lumpur: Microclimate, Outdoor Thermal Comfort And Mitigation By Land-Cover Modification, Chng Saun Fong

Student Works (2020-2029)

Urban heat island (UHI) is an urban warming phenomenon characterized by steep urban-rural temperature difference. Rapid land-use change in the urbanization process has introduced urban morphologies with impermeable surfaces and materials which causes higher heat retention in city centres. The emergence of urban hotspots is a growing concern due to the impact on the urban microclimate and human population. The comprehension of the multi-dimensional impact of UHI has become imperative to ensure good urban liveability especially in tropical cities where it is hot and humid annually. Hence, this study aims to explore the complex nexus of urban heat in terms …


Is Geographical Remoteness An Economic Disadvantage?, Jiaxuan Lu Jan 2020

Is Geographical Remoteness An Economic Disadvantage?, Jiaxuan Lu

Undergraduate Economic Review

Is the geographical location of a country deterministic to its level of economic development? Although economic geographers have been searching the answers to this question for decades, incongruities between different opinions still exist. This paper takes both theoretical and empirical approaches to provide a systematic answer to this question. Firstly, this paper uses industry-level gravity model of international trade to demonstrate that not all countries are negatively affected by geographical remoteness. Secondly, it employs a panel data of 83 countries from 2000 to 2017 and substantiates that while geographical remoteness decreases income levels and trade balances in OECD countries, it …


Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu Jan 2020

Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu

LSU Master's Theses

Urban land use and land cover (LULC) mapping has been one of the major applications in remote sensing of the urban environment. Land cover refers to the biophysical materials at the surface of the earth (i.e. grass, trees, soils, concrete, water), while land use indicates the socio-economic function of the land (i.e., residential, industrial, commercial land uses). This study addresses the technical issue of how to computationally infer urban land use types based on the urban land cover structures from remote sensing data. In this research, a multispectral aerial image and high-resolution LiDAR topographic data have been integrated to investigate …

Pass The Faa Drone Pilot Test—Remote Pilot Exam Preparation 2020, Nicolas R. Malloy Jan 2020

Pass The Faa Drone Pilot Test—Remote Pilot Exam Preparation 2020, Nicolas R. Malloy

Textbooks and Manuals Series

Part 107 is the subdivision of Subchapter F of Chapter 1 of Title 14 that pertains to small unmanned aircraft systems (sUAS). To legally fly a small unmanned aircraft for non-hobby, non-recreational use, remote pilots must abide by these regulations. This book is intended to explain the Part 107 regulations in a short and easy to read format. Additionally, this book also covers other areas of knowledge required by the FAA, including airspace and requirements, weather, loading and performance, and operations. Readers also have access to a series of sample test questions. Because the FAA does not provide specific test-questions …


Geomorphology And Chronology Of Sand Stringer Deposition Beyond The Ice Margin: Southeastern Minnesota And Western Wisconsin, Usa, Richard J. Mataitis Jan 2020

Geomorphology And Chronology Of Sand Stringer Deposition Beyond The Ice Margin: Southeastern Minnesota And Western Wisconsin, Usa, Richard J. Mataitis

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose of this Master’s thesis is to investigate linear, aeolian deposits termed “sand stringers” located within western Wisconsin and southeastern Minnesota. Previous research has investigated their spatial distribution, and to a minor extent, their composition and absolute age. However, further sedimentological and absolute age data are needed from a greater distribution of sand stringers to understand their formation and depositional chronology. To build on previous research we 1) remotely mapped the spatial distribution and orientation of sand stringers in western Wisconsin and southeastern Minnesota, 2) collected absolute age data using optically stimulated luminescence (OSL) from four stringers in western …


Examining Spatial Inequities In Green Space Distribution And Access Around The Historic City Of Savannah, Georgia., Chiamaka F. Chimah Jan 2020

Examining Spatial Inequities In Green Space Distribution And Access Around The Historic City Of Savannah, Georgia., Chiamaka F. Chimah

College of Graduate Studies: Theses & Dissertations

Green space supports recreational activities and environmental sustainability which has proven to aid physical and social well-being as well as environmental health. However, spatial inequities are observed in the distribution and accessibility of urban green space. This norm identified as an environmental justice issue has left racial minorities and people of low socioeconomic status at a disadvantage. This study adopted a geospatial approach to assess green space quantity, quality, and accessibility, and generate a green space index. This research assessed the relationship between racial structure, socioeconomic characteristics and green space inequities in all municipalities in Chatham County, Georgia with a …


Remote Sensing Approaches To Predict Forest Characteristics In Northwest Montana, Ryan P. Rock Jan 2020

Remote Sensing Approaches To Predict Forest Characteristics In Northwest Montana, Ryan P. Rock

Graduate Student Theses, Dissertations, & Professional Papers

Remote sensing can be utilized by land management organizations to save money and time. Mapping vegetation using either aerial photographs or satellite imagery and the applications for forest management are of particular interest to the Montana Department of Natural Resources. In 2018, the organization began a pilot program to test the incorporation of raster analysis of remotely sensed data into their inventory program and had limited success. This analysis identified two areas of improvement: the selection method of inventory plots and the imagery used for classification and metrics. This study found that selecting inventory plots using a generalized random tessellation …
