Use Of Unoccupied Aerial Vehicle (Drones) Based Remote Sensing To Model Platform Topography And Identify Human-Made Earthen Barriers In Salt Marshes, Joshua J. Ward

Masters Theses

Elevation is a foundational driver of salt marsh morphology. Elevation governs inundation and hydrological patterns, vegetation distribution, and soil health. Anthropogenic impacts at grand scales (e.g., rising sea levels) and local scales (e.g., infrastructure) have altered the elevation of the salt marsh surface, changing the topography and morphology of these ecosystems. This study establishes and assesses means to document and analyze these impacts using Unoccupied Aerial Vehicle (UAV) based remote sensing to model platform topography. This thesis’s first and primary study presents and compares methods of producing high-resolution digital terrain models (DTMs) with UAV-based Digital Aerial Photogrammetry (DAP) and Light …

Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek

Masters Theses

Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume …

Exchange And Social Interaction In The Tennessee River Valley: A Geospatial Approach To The Analysis Of Late Archaic Archaeological Sites, Justin S. Bailey

Masters Theses

The cultural manifestation known as the Shell Mound Archaic persisted in the lower Midwest and Midsouth region of the Eastern United States for over four millennia beginning in the Middle Archaic ca. 8900 cal BP and terminating at the end of the Late Archaic ca 3200 cal BP. A geospatial approach is applied to the analysis of exotic material exchange of the Late Archaic (ca. 5800-3200 cal BP) to assess how foraging peoples in the Tennessee River Valley interacted and persisted during this time. Exotic material items manufactured from copper, marine shell, steatite, and other nonlocal materials demonstrate distinct spatial …

Identifying Smokestacks In Remotely Sensed Imagery Via Deep Learning Algorithms, Kenneth Moss

Masters Theses

Locating smokestacks in remote sensing imagery is a crucial first step to calculating smokestack heights, which allows for the accurate modeling of dioxin pollution spread and the study of resulting health impacts. In the interest of automating this process, this thesis examines deep learning networks and how changes in input datasets and network architecture affect image detection accuracy. This initial image detection serves as the first step in automated object recognition and height calculation. While this is applicable to general land use classification, this study specifically addresses detecting smokestack images. Different dataset scenarios are generated from the massive Functional Map …

Planning For Industrial Land And Industrial Jobs: An Evaluation Of New York City's Industrial Business Zone Program, Jennifer Davis

Masters Theses

In recent years, industrial preservation policies, which aim to preserve urban industrial activity and industrial employment often through the preservation of industrial land, have emerged as a flashpoint in cities across the country that have implemented these policies. While critics contend that industrial preservation policies amount to smokestack chasing in “post-industrial” cities like New York City, industrial preservationists argue that such policies help to preserve well-paying, middle-class jobs and thus represent a tool to mitigate rising income inequalities in cities. Despite considerable attention to these policies, minimal research has evaluated the effectiveness of industrial preservation policies as land use and …

A Study On Modelling Spatial-Temporal Human Mobility Patterns For Improving Personalized Weather Warning, Yue Xu

Masters Theses

Understanding human mobility patterns is important for severe weather warning since these patterns can help identify where people are in time and in space when flash floods, tornados, high winds and hurricanes are occurring or are predicted to occur. A GIS (Geographic Information Science) data model was proposed to describe the spatial-temporal human activity. Based on this model, a metric was designed to represent the spatial-temporal activity intensity of human mobility, and an index was generated to quantitatively describe the change in human activities. By analyzing high-resolution human mobility data, the paper verified that human daily mobility patterns could be …

Spatial Patterns Of Drought Persistence In Xinjiang (A.R), China, Guzhaliayi Sataer

Masters Theses

Droughts have become one of the crucial hazards affecting Xinjiang, Northwest China, the biggest agricultural province and an important area for the grazing husbandry industry in China. Investigations about droughts in Xinjiang have been conducted from various perspectives by previous researchers. However, there are very few studies that focus on drought persistence and seasonal drought frequency. These issues are particularly important as they influence water resource management and forecasting, crop yields, agricultural development and energy consumption. Seasonal drought persistence describes how well drought conditions persist from one season to next season and is expressed as probability of persistence. In this …

Time Series Analysis Of Modis Ndvi Data With Cloudy Pixels: Frequency-Domain And Sizer Analyses Of Vegetation Change In Western Rwanda, Ephraim Robert Love

Masters Theses

Remote sensing is a valuable source of data for the study of human ecology in rural areas. In this thesis, I attempt to analyze the presence of a long-term trend indicative of post-resettlement adaptation in the vegetation signals of Western Rwanda. There is a dearth of research utilizing medium resolution imagery to study difficult environments, such as tropical-montane regions, where complex topography and cloud cover diminish image accuracy. I attempt to add to the extant literature on frequency-domain smoothing methods as well as the literature on human-environment interaction in tropical-montane regions by applying a harmonic filtering and smoothing algorithm to …

Wal-Mart Versus Meijer: A Spatial And Economic Analysis Of Supercenter Competition In Michigan, Christopher J. Washebek

Masters Theses

My research will examine the spatial and demographic strategies of supercenter firms in the State of Michigan, namely those operated by Meijer, Inc. and Wal-Mart, Inc. The competitive nature of retailing in Michigan shifted heavily in 2000 when Wal-Mart brought its Supercenter format to Michigan, making it a direct competitor to Meijer, who has operated in Michigan since 1962. Within seven years, Wal-Mart expanded its Michigan Supercenter operations from one in 2000 to forty-five in 2007. In many cases, small towns throughout the state are supporting both Meijer and a Wal-Mart Supercenter. Heavy competition of this nature between two supercenter …

This study compares and analyzes the spatial patterns of infant mortality (IM) for 1940 and 2000 using county-level socio-economic variables in the Industrial Belt, assesses the changes in IM as an indicator of the living standards for the population over time and space, and explains the changes. The region was delineated using 1940 employment data. OLS, spatial regression, and exploratory spatial data analysis were used on IM (the dependent variable) and socio-economic variables to study the standard of living in the region. Some important factors were statistically significant in the various models including: minority population, levels of industrialization, and urbanization …

Hyperspectral Remote Sensing Of Gull Lake Water Quality Summer Of 1998, Jill Downing

Masters Theses

Suspended sediments derived from surface runoff can cause deterioration in aquatic ecosystems by reducing sunlight penetrating through suspended solids to reach subsurface biological organisms. It can also have an adverse effect on recreational, agricultural, and industrial uses. Monitoring the spatial distribution of suspended sediments is important in resource management of surface waters. Field spectrometry has been applied successfully toward establishing relationships between spectral response and water quality parameters including suspended sediment concentrations. The objective of this research was to develop possible correlations between hyperspectrum and water quality attributes of depth, turbidity, and nutrients of an inland freshwater lake in southwest …

Spatial And Temporal Variations Of Cloud-To-Ground Lightning In Southern Michigan, Michael A. Crimmins

Masters Theses

Lightning has a profound impact on many aspects of modern day society. Understanding its temporal and spatial distributions is fundamental in learning to coexist with its destructive power. This study surveyed the spatial and temporal distribution of cloud-to-ground lightning over southern Michigan using data provided by the Detroit Edison Company. Flash density and 'lightning day' maps were produced for every year of the 1985 to 1995 study period and then averaged to determine long term trends. A temporal analysis determined the distribution of lightning from the inter-annual down to the diurnal scale.

The spatial analysis indicates both deficiencies in the …

Spatial And Ethnic Patterns Of Real Estate Control Affecting Upward Mobility Of Immigrants In A Nineteenth Century Industrial Community, Debra S. Alfonso

Masters Theses

The subject of immigrant success has previously been analyzed in the context of ethnic characteristics, individual heroism, worker solidarity, and advancement of industrialization. Most immigrants start at the bottom of the social-economic ladder. The mechanisms of advancement vary depending on both ethnic values and the constraints of the socioeconomic system. The key variable is normally thought to be advancing occupational status.

The problem addressed is how did recent immigrants to a 19th century steel-town obtain home ownership and advancement in spite of declining industrial wages. Using a GIS system to link and analyze geographic and historical records I was able …

Diversity And Spatial Structure Of Revitalization In The Vine Neighborhood In Kalamazoo, Michigan: 1980-1990, Lotta M. Jarnefelt-Burns

Masters Theses

Neighborhood revitalization, a process of turning an old, often run-down urban neighborhood into a fashionable and attractive place to live, has been studied in major cities in Europe, Australia and the United States. This process is a controversial combination of various social and economic changes since the late 1960s, and its magnitude and parameters have been disputed. This thesis zeroes in on one neighborhood that appears to be revitalizing, the Vine neighborhood in Kalamazoo, Michigan. The census data from 1980 and 1990 generally conflict with the revitalizing image of the area. In order to address this conflict, this research analyses …

The Relationship Of Crime Patterns To Social And Ecological Conditions In Grand Rapids, Michigan: 1980-1990, Christine L. Mcgavin

Masters Theses

The spatial distribution of the relationship between crime rates and urban ecology in Grand Rapids, Michigan over time is the focus of this study. Urban ecology can often be measured by indicators of social disorganization. Five crimes (larceny, burglary, robbery, aggravated assault, and homicide) were regressed with several indicators of social disorganization. The independent variables were poverty, transience, family disorganization, the percentage of youth in the population, race, and household density. Both violent and property crimes were strongly related to race while specific crimes were related to poverty, family disorganization, the percentage of youth in the population, and transience. Property …
