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 ...

Plain And Plateau Country, Mansour M. Elbabour

Mansour M Elbabour

Some observers of the current Libyan scene wonder why the course of the country’s ongoing revolution differed so markedly, in both duration and style, from what happened in neighboring Tunisia and Egypt. The answer may lie in our understanding of Libya’s geography, equally different from its two neighbors.


Urban Climate And Challenges Of Tropical Cities, B E. Omogbai 2011 SelectedWorks

Urban Climate And Challenges Of Tropical Cities, B E. Omogbai

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This study examines the nature of urban climate, features and the challenges on the developing tropical cities in the 21st century. It argues that the use of principles of urban climate would help in providing comfortable living conditions and problem immune working environments for the inhabitants of tropical cities. The findings reveal that owing to poor environmental planning, inadequate geotechnical landscape surveys prior to the development of urban infrastructures, and non-adherence to the principles of urban climate, challenges of landscape degradation, excessive flooding of the built infrastructures, heat-island effects, and collapse of buildings have emerged. Suggested measures to avert these ...

Crime And Social Strain In Fairfax County, Va : Using Geographical Information Science To Test For Social Strain In The Aftermath Of The Great Recession, Jason D. Reyes

Geography and the Environment: Graduate Student Capstones

Robert Merton, through the Social Strain Theory, suggests that crime exists because of society’s demands do not meet individuals needs. The following study is a qualitative study that first explains what the Social Strain Theory is, then tests to see if this theory has any validity to one of the most affluent counties in the United States. This study compares Fairfax County’s socioeconomic variables with the their crime data during the Great Recession to uncover any trends or patterns for which Robert Merton would say are due to high amounts of Social Strain. The overall results of the ...

Geopolitics Of The Kaliningrad Exclave And Enclave: Russian And Eu Perspectives, Alexander Diener, Joshua Hagen 2011 Marshall University

Geopolitics Of The Kaliningrad Exclave And Enclave: Russian And Eu Perspectives, Alexander Diener, Joshua Hagen

Geography Faculty Research

Two U.S. political geographers examine a range of geopolitical issues associated with the shifting sovereignty of Russia's Kaliningrad Oblast (a part of the former German province of East Prussia) during the 20th century, as well as the region's evolving geopolitical status as a consequence of the European Union's enlargement to embrace Poland and Lithuania. They argue that Kaliningrad today can be considered a "double" borderland, situated simultaneously on the European Union's border with Russia as well as physically separated from Russia, its home country, by the surrounding land boundaries of EU states. Although technically neither ...


The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore 2011 University of Southern Mississippi

The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore

Master's Theses

There is renewed interest in disease surveillance due to the persistence of numerous vector-borne diseases. Though the life-history processes of disease vectors are known to dictate their distribution patterns, it has been hypothesized that vectors, such as local mosquito abundance, could be predicted from factors such as climate and land use/land cover. Remote sensing has been used as a supplement to traditional methods of mosquito surveillance and to map the spatial distribution of mosquito habitats. This, in turn, affords optimism for improved vector/disease management to identify the best use of remote sensing data and geo-statistical techniques to predict ...


The Role Of Landscape In The Distribution Of Deer-Vehicle Collisions In Two Counties In South-Central Mississippi, Jacob Jeremiah McKee 2011 University of Southern Mississippi

The Role Of Landscape In The Distribution Of Deer-Vehicle Collisions In Two Counties In South-Central Mississippi, Jacob Jeremiah Mckee

Master's Theses

The number of deer killed by vehicle collisions each year in the United States exceeds the number of deer killed annually through hunting. Deer-vehicle collisions (DVCs) have a vast negative impact on the economy, traffic safety, and general wellbeing of otherwise healthy deer populations. To mitigate DVCs, it is imperative to gain a better understanding of the factors that play a role in their spatial distribution. Much of the existing research has been inconclusive, pointing to a variety of factors that cause DVCs that are specific to study site and region. Very little DVC research has been undertaken in the ...


Land Cover Study In Iowa: Analysis Of Classification Methodology And Its Impact On Scale, Accuracy, And Landscape Metrics, Sarah Ann Porter 2011 University of Iowa

Land Cover Study In Iowa: Analysis Of Classification Methodology And Its Impact On Scale, Accuracy, And Landscape Metrics, Sarah Ann Porter

Theses and Dissertations

For landscapes dominated by agriculture, land cover plays an important role in the balance between anthropogenic and natural forces. Therefore, the objective of this thesis is to describe two different methodologies that have been implemented to create high-resolution land cover classifications in a dominant agricultural landscape. First, an object-based segmentation approach will be presented, which was applied to historic, high resolution, panchromatic aerial photography. Second, a traditional per-pixel technique was applied to multi-temporal, multispectral, high resolution aerial photography, in combination with light detection and ranging (LIDAR) and independent component analysis (ICA). A critical analysis of each approach will be discussed ...


A Production Method For Conversion Of Scanned Historic Aerial Imagery Into Orthophotos Using The Rational Function Model, Alexis Buchwald 2011 University of Redlands

A Production Method For Conversion Of Scanned Historic Aerial Imagery Into Orthophotos Using The Rational Function Model, Alexis Buchwald

MS GIS Program Major Individual Projects

Historical aerial photographs are a valuable resource for the Center for Conservation Biology because they offer land cover and land use data from the past at high spatial resolution. The imagery which the CCB currently holds, however, is not geo-referenced, so finding imagery for a particular site and using it in geographic software is difficult. A method was developed using the rational function model to convert scanned photos into imagery with a spatial reference system, while at the same time correcting for distortions caused by elevation changes. The rational function model uses a digital elevation model and a spatial reference ...

Other empirical data collected included the address(es) of the buildings, the number of stories and/or mailboxes, land use categories such as commercial or residential (including exclusive as well as mixed use categories), the name and type of business, and the spatial coordinates of the building (latitude/longitude). This data was collected in order to provide an objective "picture" of ...


Automatic High-Fidelity 3d Road Network Modeling, Jie Wang 2011 Old Dominion University

Automatic High-Fidelity 3d Road Network Modeling, Jie Wang

Computational Modeling and Simulation Engineering Theses & Dissertations

Many computer applications such as racing games and driving simulations frequently make use of 3D high-fidelity road network models for a variety of purposes. However, there are very few existing methods for automatic generation of 3D realistic road networks, especially for those in the real world. On the other hand, vast road network GIS data have been collected in the past and used by a wide range of applications, such as navigation and evaluation. A method that can automatically produce 3D high-fidelity road network models from 2D real road GIS data will significantly reduce both the labor and time needed ...

Make Farming Energy Efficient, William Moseley 2011 Macalester College

Make Farming Energy Efficient, William Moseley

William G Moseley

This op-ed argues that American agriculture must become more energy efficient if it is to remain globally competitive and ecologically sound. This issue is of critical importance to the nation's farmers who are likely to receive record high prices for their crops in 2011, but low profits because of skyrocketing input costs. The piece further questions why Democratic presidents, who have a history of pushing for energy efficiency and conservation, have continued to support high energy input agriculture. The article also challenges arguments suggesting that high-input agriculture is needed to feed the world.
