Polarimetric SAR (POLSAR) provides a rich set of information about objects on land surfaces. However, not all information works on land surface classification. This study proposes a new, integrated algorithm for optimal urban classification using POLSAR data. Both polarimetric decomposition and time-frequency (TF) decomposition were used to mine the hidden information of objects in POLSAR data, which was then applied in the C5.0 decision tree algorithm for optimal feature selection and classification. Using a NASA/JPL AIRSAR POLSAR scene as an example, the overall accuracy and kappa coefficient of the proposed method reached 91.17% and 0.90 in the L-band, much higher …

The goal of this research was to evaluate the extent of land use change occurring in the Sebago lake watershed of southern Maine. The primary data set used was Landsat 7 Near Infrared satellite imagery of the region which was analyzed with ESRI’s ArcGIS soQware. Data was clipped to the Portland Water District’s sub watershed shape file and analyzed with the soQware’s image analysis ‘difference’ tool which calculates the differences in pixel values between to raster datasets. The 2013 Landsat reclassifica-on was compared to 1987, 1995 and 2009 reclassifica-ons. NOAA’s Habitat Priority Planner plugin tool was also u-lized in order …

Field size distributions and their changes have not been studied over large areas as field size change datasets are not available. This study quantifies agricultural field size changes in a consistent manner using Landsat satellite data that also provide geographic context for the observed decadal scale changes. Growing season cloud-free Landsat 30 m resolution images acquired from 9 to 25 years apart were used to extract field object classifications at seven sites located by examination of a global agricultural yield map, agricultural production statistics, literature review, and analysis of the imagery in the US Landsat archive. High spatial resolution data …

The Perpetual Uncertainty Of Civil Society: Case Study Of An Anti-Hunger Organization In South Africa, Daniel N. Warshawsky
Geography Faculty Publications
South Africa has one of the most active civil societies in the world, with more than 85,000 registered civil society organizations (CSOs). However, the growth of CSOs in post-apartheid South Africa does not necessarily imply that the sector is strong. While it is true that the demise of the apartheid regime increased democratic representation within South Africa, CSOs have experienced a series of institutional challenges which have weakened their organizational stability. This has included increased oversight by the state, inefficient and inconsistent funding from government, fickle demands by private donors, and competition from other sectors. Through an in-depth case study …

Automated Segmentation, Detection And Fitting Of Piping Elements From Terrestrial Lidar Data, Yun-Ting Su
Open Access Dissertations
Since the invention of light detection and ranging (LIDAR) in the early 1960s, it has been adopted for use in numerous applications, from topographical mapping with airborne LIDAR platforms to surveying of urban sites with terrestrial LIDAR systems. Static terrestrial LIDAR has become an especially effective tool for surveying, in some cases replacing traditional techniques such as electronic total stations and GPS methods. Current state-of-the-art LIDAR scanners have very fine spatial resolution, generating precise 3D point cloud data with millimeter accuracy. Therefore, LIDAR data can provide 3D details of a scene with an unprecedented level of details. However, automated exploitation …

The photographs of On Nine Mile were made to explore my developing relationship with the place I now inhabit. They compare the reality of a place against preconception and actual experience versus idealized expectations. I made this work to help understand a landscape to which I was transplanted and to which I had no connection. This exhibition is comprised of photographs taken at a section of untilled prairie called Nine Mile that most closely resembled my visual preconception of the Great Plains. I grew up in the Pacific Northwest surrounded by the mountains, forests, and shoreline that typify the landscape …

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-Wildlife Conflict In Selela Village, Nicole Chlebek, Laura Stalter
Independent Study Project (ISP) Collection
The beastly journey of long-distance migration for the African Elephant (Lexodonta Africana) is important for upholding their connections between diminishing protected areas, especially in northeastern Tanzania. However, human development is encroaching into these corridors, creating a human-elephant conflict, which can ruin livelihoods of villagers, depending on the extent of conflict. This study focused on exploring the hypothesized human-elephant conflict on the Selela corridor, specifically in Selela village, as well as GPS (Global Positioning System) mapping evidence of elephant travel along the projected Selela elephant corridor connecting Ngorongoro Conservation Area (NCA), to Selela Forest Reserve (SFR), and finally to Manyara Ranch. …

Uganda is a beautiful country filled with an extensive amount of natural resources, one of the most profound being wetlands. It is said that these wetlands are a crucial source of food and water for almost 3 million people (NEMA, 2012 and Oguttu et.al, 2008). They also provide many more invaluable socioeconomic benefits for the country. As Uganda experiences increasing development as well as a rapidly increasing population, the wetlands become increasingly necessary, at the same time they become increasingly threatened. It is written in the 1995 Ugandan constitution that Ugandan policy is aimed at ensuring sustainable development for the …

Non-Compliance In Marine Reserves: Measuring The Drivers Of Behavior Among Recreational Fishermen Within The Great Barrier Reef Marine Park, Nick Manning

The Great Barrier Reef Marine Park (GBRMP) provides outstanding ecological, cultural, social, and economic services to the number of communities that use it. Most of the park is regulated via a zoning system designed to protect its biodiversity and ensure the sustainable use of its resources (GBRMPA, 2004). Like any social institution, zoning regulations rely heavily on compliance in order to be effective. Recreational fishing on the GBRMP accounts for most of the noncompliance behavior associated with zoning (Arias and Sutton, 2013). Thus, understanding fishers compliance behavior is central to understanding how to best manage these areas. Using results from …

Placeness: Mongolia A Call For The Creation Of A Human Impact Assessment, C. Winston Kies
Independent Study Project (ISP) Collection
Sense of place, place-‐based identities, and “placeness” are fundamental ways through which human beings understand their physical place in the world. The means by which most Mongolians—and indeed most human beings—strive for placeness is fairly simple. First, one decides what location will become their place. Their place may be predetermined (i.e. a birthplace) or chosen (based on the wildlife, the scenery, the neighborhood, etc.). Once one has a place, sense of place necessarily follows. One’s place becomes the standard by which locations are understood, and by which one understands oneself. The latter process constitutes the formation of place-‐based identities, which …

Himalayan communities stand precariously in an era of phenomenological uncertainty. Climate change is merely a lens through which we may observe and begin to understand such localized modern complexities. The people of the Tarap Valley in Dolpo, Nepal have experienced an increase in avalanches, snow leopard attacks and unpredictable precipitation patterns in recent years. In upper Mustang, Nepal, people have endured the harshest winter in generations and suffered from reduced water access. Environmental, climatic and weather related changes in both Himalayan districts have severely impacted traditional livelihoods and led some to adopt modern means of adaptation. Despite the scientific evidence …

The Impact Of Bus Rapid Transit Implementation On Residential Property Values: A Case Study In Reno, Nv, Steven Thomas Ulloa
USF Tampa Graduate Theses and Dissertations
Since literature that evaluates the impacts that Bus Rapid Transit (BRT) has on surrounding property values is limited, this research contributes to this research by investigating if proximity to a BRT station has an effect, either positive or negative, on residential housing values. Further, it investigates if the nature and extent of this effect varied during different stages of implementation of the BRT system and different housing market conditions. Fluctuations in sale prices were mitigated based on a six month moving median. Four hedonic price models were then used to evaluate the influence of independent variables on the dependent variable, …

Hurricane risk characteristics are examined across the U. S. Gulf of Mexico coastline using a hexagonal tessellation. Using an extreme value model, parameters are collected representing the rate or λ (frequency), the scale or σ (range), and the shape or ζ (intensity) of the extreme wind distribution. These latent parameters and the 30-year return level are visualized across the grid. The greatest 30-year return levels are located toward the center of the Gulf of Mexico, and for inland locations, along the borders of Louisiana, Mississippi, and Alabama. Using a geographically weighted regression model, the relationship of these parameters to sea …
