Spatial Pattern Analysis Of Agricultural Soil Properties Using Gis, Corrin Jared Mccarn
Spatial Pattern Analysis Of Agricultural Soil Properties Using Gis, Corrin Jared Mccarn
Theses and Dissertations
Agricultural soil properties exhibit variation over field plot scales that can ultimately effect the yield. This study performs multiple spatial pattern analyses in order to design spatially dependent regression models to better understand the interaction between these soil properties. The Cation Exchange Capacity (CEC) and Calcium-Magnesium Ratio (CaMgR) are analyzed with respect to Calcium, Magnesium, and soil moisture values. The CEC and CaMgR are then used to determine impact on the yield values present for the field. Results of this study show a significant measure of model parsimony (0.979) for the Geographically Weighted Regression (GWR) model of the CEC with …
Evaluating Long-Term Land Cover Changes For Malheur Lake, Oregon Using Envi And Arcgis, Ryan Joseph Woods
Evaluating Long-Term Land Cover Changes For Malheur Lake, Oregon Using Envi And Arcgis, Ryan Joseph Woods
Theses and Dissertations
Land cover change over time can be a useful indicator of variations in a watershed, such as the patterns of drought in an area. I present a case study using remotely sensed images from Landsat satellites for over a 30-year period to generate classifications representing land cover categories, which I use to quantify land cover change in the watershed areas that contribute to Malheur, Mud, and Harney Lakes. I selected images, about every 4 to 6 years from late June to late July, in an attempt to capture the peak vegetation growth and to avoid cloud cover. Complete coverage of …
Women Workin’ It In Gis: A Mixed Methods Study Of Underrepresentation And The Gendered Experience Among Female Gis Practitioners, Livia M. Betancourt Mazur
Women Workin’ It In Gis: A Mixed Methods Study Of Underrepresentation And The Gendered Experience Among Female Gis Practitioners, Livia M. Betancourt Mazur
Theses and Dissertations
Through novel empirical research, this thesis explores the experience of women working in the professional field of geographic information systems (GIS), adding to GIS literature, as well as to academic geography and wider science, technology, engineering and mathematics (STEM) discourses, addressing gaps in these bodies of knowledge.
Transportation And Sanitation Drivers Of Land Use/Land Cover Change: Loss Of The Jamaica Bay Wetlands, Margaret Joy Cytryn
Transportation And Sanitation Drivers Of Land Use/Land Cover Change: Loss Of The Jamaica Bay Wetlands, Margaret Joy Cytryn
Theses and Dissertations
This thesis presents an analysis (1830-2014) of the historical events of land use/land cover change in the Jamaica Bay estuary, identification of the agents of change, and a perspective on the potential drivers of transportation and sanitation in land use/land cover change.
A Gis Analysis Of Sidewalk Infrastructure In Starkville, Ms, Robert Devon Bise
A Gis Analysis Of Sidewalk Infrastructure In Starkville, Ms, Robert Devon Bise
Theses and Dissertations
Sidewalks provide many community services, yet not much geospatial research exists regarding sidewalks, especially in Mississippi. The purpose of this thesis was to use geographic information systems to inventory and map sidewalks for Starkville, MS and to compare sidewalk availability and quality to 2010 US census block demographics. In Starkville, sidewalks served 28% of the census block population, which classifies the city as “Car-Dependent” according to a Walk Score criteria. Majority minority census blocks and majority white census blocks had similar proportions of sidewalks. However, 97% of “Excellent” quality and 64 more sections of ADA compliant sidewalks were within majority …
Utilizing Remote Sensing Imagery To Monitor Vegetation Change Within World Heritage Sites, Mimi Eve Hatzis
Utilizing Remote Sensing Imagery To Monitor Vegetation Change Within World Heritage Sites, Mimi Eve Hatzis
Theses and Dissertations
ABSTRACT
World Heritage sites provide a glimpse into the stories and civilizations of the past. There are currently 1007 unique World Heritage properties with 779 being classified as cultural sites, 197 as natural sites, and 31 falling into the categories of both cultural and natural sites (UNESCO & World Heritage Centre, 1992-2015). However, of these 1007 World Heritage sites, at least 46 are categorized as in danger and this number continues to grow. These unique and irreplaceable sites are exceptional because of their universality. Consequently, since World Heritage sites belong to all the people of the world and provide inspiration …
Effects Of Physical Characteristics Of Urban Storm Sewersheds On Water Quality In Bloomington, Il, Alicia Terese O'Hare
Effects Of Physical Characteristics Of Urban Storm Sewersheds On Water Quality In Bloomington, Il, Alicia Terese O'Hare
Theses and Dissertations
Increasing urbanization has consequences for surface water quality. Stormwater is a large component of urban water degradation that is poorly understood. Precipitation is quickly transported via underground pipes, from the land to the stream without following water's natural flow path. Studies have correlated detention ponds with improved water quality and impervious surface cover with degraded water quality. However, other physical characteristics within a storm sewer shed including the presence of sump pumps, area and pipe miles may also affect the stormwater quality. We chose 18 storm sewer systems in Bloomington, IL. We measured pH, temperature, conductivity, dissolved oxygen, chloride, nitrate, …
