Surface Modeling Topsoil Distribution On A Reclaimed Coal-Mine Site At Blackmesa Mine Complex, Kayenta, Arizona, Janine Ferarese

Geography and the Environment: Graduate Student Capstones

A necessary precursor to ensure proper vegetation growth on reclaimed coal-mine areas is even distribution of topsoil. This capstone discusses development of surface models to describe the accurate determination and visualization of the distribution of topsoil. Prediction surfaces from topsoil-depth point samples were created using the surface interpolation methods, Inverse Distance Weighted and Kriging. The validity and accuracy of each method was assessed to determine the best method to evaluate actual topsoil distribution at a coal mining site. The model can be utilized by non- spatially trained personnel working in the mining arena as an aid in assessing how appropriately …

From Lakes To Plants: Spatial Assessment Of Vegetation Dynamics Along 52 Disappearing Lakes In The Boreal Forests Of Alaska From 1984-2009 In The Yukon Flats Wildlife Refuge, Steve Ewest

Geography and the Environment: Graduate Student Capstones

A spatial assessment of vegetation change along the areas of shrinking lakes was conducted in 2011. The analysis utilized Landsat TM/ETM imagery bands 3 and 4 to calculate NDVI (normalized difference vegetation index) from 1984 to 2009 and applied cell and zonal statistics to measure the change as well as create an animation of the change. Also, three 30 meter bands and the zonal averages for the maximum values were assessed. The band in the 60-90 buffer bands has the greatest ratio amount of the maximum vegetation values when compared to the 0-30 meter and the 30-60 meter buffered bands. …

Farm Fragmentation: Mapping The Status And Trends Of Agricultural Lands In Colorado, Gabrielle Friedman

Geography and the Environment: Graduate Student Capstones

Statistical spatial analysis was used in this research to assess the factors contributing to the downsizing of farms as well as overall farm size choice in Colorado. The areas of research focus will be the spatial effects and the economic landscape. This work will challenge the common belief that large, corporate farms are swallowing up small farms in a consolidation effort. Further, the analysis will quantify and visualize the status of agricultural lands in Colorado. The research will help to inform the theoretical understanding of agricultural decision processes within the context of economic and spatial factors.

High School Graduation And Dropout Rates In The Pikes Peak Region Of Colorado: A Spatial Analysis Of School Proximity To Military Installations, Rachel Orlicky

Geography and the Environment: Graduate Student Capstones

The purpose of this project was to examine graduation and dropout rates for high school students to determine if a correlation could be found with respect to the relative school distance from a military installation in the Pikes Peak region. Spatial analysis and Ordinary Least Squares analysis were used to build a linear regression model to predict student graduation and dropout rates. The results for the total student population for graduation rates and for dropout rates showed no statistically significant correlation with respect to the relative proximity to a military installation. Detailed analysis revealed that several minority and gender subgroups …

Mapping In Philanthropy: Exploring The Use Of Mapping In Foundation Grantmaking, Jim Casey

Geography and the Environment: Graduate Student Capstones

Foundations provide grants to nonprofit organizations in our communities, who then provide services locally. Choosing which nonprofit to fund, and which not to fund is difficult. This study examines current uses and upcoming uses of mapping and Geographic Information Systems (GIS) as part of funding decisions made by foundations. Foundations engaged in strategic funding, especially that which targets specific populations are more likely to use GIS and geospatial analysis in funding decisions. Grantmaking in response to proposals requires less strategic analysis and calls for mapping much less by comparison. As a field, nationally foundations and nonprofits have identified many uses …

A Gis Model To Predict Feral Pig (Sus Scrofa) Habitat On Vandenberg Air Force Base, California, Brian Schnick

Geography and the Environment: Graduate Student Capstones

The applicable Natural Resource area of this project is animal control and wildlife management, as wild pigs can be quite destructive to landscapes (Campbell, et al., 2010) (McCann, et al., 2008). Geographic Information System (GIS) predictive models have proven to be useful in regards to other mammals (Travaini, et al., 2007), raptors (Bustamante, et al., 2004), and pest species such as locusts (van der Werf, et al., 2005). Pigs are often nocturnal and bed down in heavy cover, hindering direct observation. Additionally, Vandenberg Air Force Base (VAFB) encompasses over 400 square kilometers. Therefore, predictive modeling is an appropriate method for …

Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo

Geography and the Environment: Graduate Student Capstones

Meteorologists are continually working toward a greater understanding of which atmospheric environments are most conducive for tornado development. This Capstone project analyzed tornado occurrences across Texas, Oklahoma, Arkansas and Louisiana during the period 1950 through 2009 to determine if any correlation exists between the location and frequency of tornado activity and the phases of the El Nino-Southern Oscillation, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. While it was determined that no phase of any of the oscillations studied was significantly more dominant over the other(s) concerning frequency, this project does identify some spatial shifts in tornado activity depending …

Determining Heritage Oak Tree Susceptibility To Sudden Oak Death Using Gis Risk Analysis, Michelle M. Guzdek

Geography and the Environment: Graduate Student Capstones

Sudden Oak Death (SOD), caused by the pathogenic water mold Phytophthora ramorum, has killed hundreds of thousands of oak trees in the California coastal regions, with redwood-tanoak forests being hit the hardest (Shoemaker et al., 2007). The term “sudden oak death” is used to describe the disease, because of how rapidly the pathogen has killed otherwise healthy tanoaks, virtually in a matter of weeks (COMTF 2010). SOD was first reported in California in 1994 and is believed to have originated from infected nursery or ornamental plants, but the source has never been identified (Mascheretti et al. 2008).

Once potential wind harvesting areas have been identified, concluding analysis will determine the amount of energy generated in efforts to offset current energy use. Harvesting wind has dated back to the 7^th century and is looked at as a mature technology (Edwards 2003). Over the past few decades, public attitudes towards wind harvesting is becoming …

Gis Applications For Coal Mine Subsidence In The State Of Colorado, Charles J. Strickler

Geography and the Environment: Graduate Student Capstones

The state of Colorado has an extensive history of subsurface coal mining. Due to the widespread extraction of coal, numerous subsidence events have occurred, causing both costly and potentially dangerous conditions. The two most common types of underground coal mines in Colorado are slope and shaft mines, which are prone to roof collapse that can propagate to the surface in the form of sinkholes and troughs. Sinkholes and troughs can occur over prolonged periods of time or as instantaneous events, which may leave landowners little reaction time and expensive repairs. As of January 2010, no spatial database existed that covered …
