Accuracy Assessment Of Measuring Linear And Areal Features In Aerial Imagery, I-Kuai Hung, David L. Kulhavy, Daniel R. Unger, Reid A. Viegut, Yanli Zhang, Nicholas C. Schiwitz Dec 2023

Accuracy Assessment Of Measuring Linear And Areal Features In Aerial Imagery, I-Kuai Hung, David L. Kulhavy, Daniel R. Unger, Reid A. Viegut, Yanli Zhang, Nicholas C. Schiwitz

International Journal of Geospatial and Environmental Research

As part of natural resource education in the Arthur Temple College of Forestry and Agriculture at Stephen F. Austin State University (SFASU), students were instructed to take areal and linear measurements of grounds remotely using available platforms including aerial orthomosaic derived from UAS (unmanned aerial system) acquired imagery, Google Earth Pro, and Pictometry. The onscreen measurement was conducted at five different map scales, 1/1000, 1/2000, 1/3000, 1/4000, and 1/5000. Accuracy of the measurements was assessed by comparing the onscreen measurements to ground truth data verified with a measuring tape. Results show that measurements based on the UAS were more accurate …

Big Data Applications And Challenges In Giscience (Case Studies: Natural Disaster And Public Health Crisis Management), Amir Masoud Forati Dec 2023

Big Data Applications And Challenges In Giscience (Case Studies: Natural Disaster And Public Health Crisis Management), Amir Masoud Forati

Theses and Dissertations

This dissertation examines the application and significance of user-generated big data in Geographic Information Science (GIScience), with a focus on managing natural disasters and public health crises. It explores the role of social media data in understanding human-environment interactions and in informing disaster management and public health strategies. A scalable computational framework will be developed to model extensive unstructured geotagged data from social media, facilitating systematic spatiotemporal data analysis.The research investigates how individuals and communities respond to high-impact events like natural disasters and public health emergencies, employing both qualitative and quantitative methods. In particular, it assesses the impact of socio-economic-demographic …

Beyond Borders: Representations Of Refugees And Place In Clarkston, Georgia, Sarah Ryniker Aug 2023

Beyond Borders: Representations Of Refugees And Place In Clarkston, Georgia, Sarah Ryniker

Theses and Dissertations

In the last thirty years, socio-political shifts within the city of Clarkston, Georgia, have led to an evolution in representations of the city and of its many refugee and immigrant populations. This dissertation examines the site-specific effects of the evolving policies and practices of refugee resettlement and integration within the city of Clarkston and the emerging immigrant gateway of the South. While the city itself has transformed, so have its representations of refugees, challenging imaginative geographies and complicating the mainstream dichotomic racial imaginative geographies and socio-political representation of the U.S. South. Using qualitative methods, I analyze materials from four years …

Comparing Drone2map Versus Pix4dmapper When Creating Orthophoto Mosaics Over Homogeneous Land Features, Victoria Williams, Daniel R. Unger, David Kulhavy, I-Kuai Hung, Yanli Zhang Jul 2023

Comparing Drone2map Versus Pix4dmapper When Creating Orthophoto Mosaics Over Homogeneous Land Features, Victoria Williams, Daniel R. Unger, David Kulhavy, I-Kuai Hung, Yanli Zhang

International Journal of Geospatial and Environmental Research

This study evaluated two popular software packages currently used within the natural resources profession to create orthophoto mosaics: Drone2Map and Pix4Dmapper. Of particular concern was how effective these two software packages would perform in creating orthophoto mosaics over a city park in East Texas consisting of forest, open grass, and urban concrete surrounding a lake. Two drone flights over the city park were conducted. One flight was at 76 meters (250 feet) above ground with a single pass configuration. The other flight was at 122 meters (400 feet) above ground with a double pass configuration. Upon the completion of each …

Visibility And Intervisibility: A Viewshed Analysis Of The Oneota Component Of The Lake Koshkonong Locality, Rebekah Joy Gansemer May 2023

Visibility And Intervisibility: A Viewshed Analysis Of The Oneota Component Of The Lake Koshkonong Locality, Rebekah Joy Gansemer

Theses and Dissertations

This research was conducted to analyze the visual relationship between Oneota village sites, Late Woodland habitations, and mound sites during a period of time that saw all of these groups living contemporaneously on Lake Koshkonong. My research seeks to not only understand what and who Oneota sites could see on the landscape, but also who might have been able to see them. This research adds to the discussion of Lake Koshkonong Oneota relationships with contemporaneous groups during the 11th-15th centuries.This study focuses on four sites within the Lake Koshkonong Locality that date to the Oneota period: Crescent Bay Hunt Club …

Black Autonomy As A Form Of Resistance And A Symbol Of Rebellion: A Comparative Study Of Robbins, Illinois, And Milwaukee Bronzeville (1920-1970), Nateya Taylor May 2023

Black Autonomy As A Form Of Resistance And A Symbol Of Rebellion: A Comparative Study Of Robbins, Illinois, And Milwaukee Bronzeville (1920-1970), Nateya Taylor

Theses and Dissertations

Black towns and segregated Black neighborhoods are two examples of majority Black communities that were formed because of the racial discrimination African Americans faced. Previous research has examined majority Black communities from a deficit model; however, this paper highlights the assets of autonomy and resistance in two majority Black communities in the Midwest: Robbins, Illinois, and Milwaukee Bronzeville. This paper compares Robbins, Illinois, a Black town, and Milwaukee’s Bronzeville neighborhood, a segregated Black community, to answer the questions: How did African Americans in Robbins, Illinois, and Milwaukee Bronzeville use autonomous practices to navigate racial discrimination between 1920 and 1970? What …
