Global Population Distributions And The Environment : Discerning Observed Global And Regional Patterns., Jeremiah J. Nieves

Electronic Theses and Dissertations

Between 1990 to 2015, numerous groups used ancillary data about the environment surrounding populations to more accurately map global populations from standard census data. No comprehensive study has been undertaken to characterize the observed relationships between population density and ancillary data. Better understanding these relationships may produce more accurate population maps, focus resources on new datasets with a high probability of modelling importance, and lead to expanded end-user applications. This study examined these relationships by extracting variable importances from 36 independently run, country-specific population models from the WorldPop project’s population data. Covariate data describing urban/suburban extents were found to be …

Technique Comparisons For Estimating Fragility Analysis In The Central Mid-West, Kimberly Ann Walker

Masters Theses & Specialist Projects

Climate change studies and examinations of increasing sea levels and temperatures show storm intensity and frequency are increasing. As these storms are increasing in intensity and frequency, the effects of these storms must be monitored to determine the probable damages or impacts to critical infrastructure [2, 35]. These storms suddenly create new demands and requirements upon already stressed critical infrastructure sectors [1]. A combined and interdisciplinary effort must be made to identify these stresses and to mitigate any failures. This effort is needed so that the 21st Century Smart Grid is robust and resilient enough to ensure that the grid …

A General Method To Normalize Landsat Reflectance Data To Nadir Brdf Adjusted Reflectance, David P. Roy, Hankui Zhang, Junchang Ju, Jose Luis Gomez-Dans, Philip E. Lewis, Crystal Barker B. Schaaf, Qingsong Sun, Jian Li, Haiyan Huang, V. Kovalskyy

GSCE Faculty Publications

The Landsat satellites have been providing spectacular imagery of the Earth's surface for over 40 years. However, they acquire images at view angles ±7.5° from nadir that cause small directional effects in the surface reflectance. There are also variations with solar zenith angle over the year that can cause apparent change in reflectance even if the surface properties remain constant. When Landsat data from adjoining paths, or from long time series are used, a model of the surface anisotropy is required to adjust all Landsat observations to a uniform nadir view (primarily for visual consistency, vegetation monitoring, or detection of …

Past Meets Future: Combining Gis, 3d Technologies, And Legacy Data To Reanalyze Ceramics At Copan, Honduras, Stephanie Sterling, Heather Richards-Rissetto, René Viel

Public Participatory Gis And The Geography Of Inclusion, Steven M. Radil, Junfeng Jiao

Research Collection College of Integrative Studies

Public participatory geographic information systems (PPGIS) have been advanced as a means to include those who have been traditionally excluded from numerous place-specific governance activities, including planning and policymaking and as a way to resolve some of the long-standing tensions between critical traditions in human geography and the ever-expanding field of GIS. Despite the rapid adoption of participatory GIS by academics, government officials, and planning professionals, there are few guidelines of best practices for PPGIS researchers and practitioners to draw on and little effort has been made to understand how and in what ways PPGIS efforts are (or perhaps are …

Application Of Spatial And Descriptive Analysis Methods To Determine Relationship Between Hardware Subsidies And The Sanitation Marketplace, Danielle Devuyst

USF Tampa Graduate Theses and Dissertations

Sanitation marketing is an emerging approach of strengthening the local private sector to implement scalable and sustainable improved sanitation coverage in developing countries, specifically among the poor. It encourages the enhancement of sanitation market supply and demand by developing distribution infrastructure and stimulating consumer interest. Unlike interventions that provide hardware subsidies to initiate sanitation demand, financial support for sanitation marketing is used exclusively for the research and development of the market; this encourages the private sector to become independent and self-sufficient. Qualitative data suggests that while sanitation marketing projects have been successful at implementing replicable and sustainable sanitation coverage, they …

A Model Of The Effects Of Deforestation On Local Climate In The North Cascades, Monica R. H. Jasper

Geography and the Environment: Graduate Student Capstones

Changes in areal extent of land cover types may lead to alterations in the surface energy budget that contribute to anthropogenic climate forcing. This study examines the effects of deforestation in the Cascade Range on local temperature. Temperature sensors were installed in 14 forest stands, taking measurements for one year. Estimated tree age, circumference, and species were recorded to calculate stand density index. Satellite imagery was used to calculate shade fraction from spectral mixture analysis, which is a proxy for canopy structure and density. These data were used to construct seasonal cycles of temperature to model variation with stand density …

Towards Integrated Historical Climate Research: The Example Of Atmospheric Circulation Reconstructions Over The Earth, R. Allan, G. Endfield, V. Damodaran, G. Adamson, M. Hannaford, F. Carroll, N. Macdonald, N. Groom, J. Jones, Fiona Williamson, E. Hendy, P. Holper, J. Pablo, L. Hughes, L. Arroyo-Mora, R. Bickers, A.-M. Bliuc

Research Collection College of Integrative Studies

Climate change has become a key environmental narrative of the 21st century. However, emphasis on the science of climate change has overshadowed studies focusing on human interpretations of climate history, of adaptation and resilience, and of explorations of the institutions and cultural coping strategies that may have helped people adapt to climate changes in the past. Moreover, although the idea of climate change has been subject to considerable scrutiny by the physical sciences, recent climate scholarship has highlighted the need for a re-examination of the cultural and spatial dimensions of climate, with contributions from the interpretive humanities and social sciences. …

A Statistical Assessment Of Maritime Socioeconomic Indicators For The European Atlantic Area, Javier Fernandez-Macho

Journal of Ocean and Coastal Economics

Ever since the introduction into marine and maritime policy strategies worldwide of the relatively new concept of Blue Growth there has been an increasing interest in developing integrated systems of indicators for the maritime economy.

The Marnet project has been a recent attempt to develop a comparative maritime socioeconomic framework for the European Atlantic area and its database contains a large number of socioeconomic indicators for many maritime activities at different territorial levels that provide the information needed to help analyze and compare the maritime economy of the European Atlantic regions.

However, there are still many gaps with respect to …

Is The Closest Facility The One Actually Used? An Assessment Of Travel Time Estimation Based On Mammography Facilities, Jennifer Alford-Teaster, Jane M. Lange, Rebecca A. Hubbard, Christoph I. Lee, Jennifer S. Haas, Xun Shi, Heather A. Carlos, Louise Henderson, Deirdre Hill, Anna N. A. Tosteson, Tracy Onega

Dartmouth Scholarship

Characterizing geographic access depends on a broad range of methods available to researchers and the healthcare context to which the method is applied. Globally, travel time is one frequently used measure of geographic access with known limitations associated with data availability. Specifically, due to lack of available utilization data, many travel time studies assume that patients use the closest facility. To examine this assumption, an example using mammography screening data, which is considered a geographically abundant health care service in the United States, is explored. This work makes an important methodological contribution to measuring access--which is a critical component of …

Cruising The Canal: A Methodological Approach To Assessing Trail Conditions Along The Hennepin Canal Parkway, Alyssa Clarida

Geography: Student Scholarship & Creative Works

Trail conditions in the United States are degrading and trail systems do not receive enough funding to repair them in a timely manner. Park managers often conduct trail assessments to collect trail condition data. They use this data to make timely and judicious decisions regarding trail repairs. However, many trail assessments are time consuming, costly, and require high levels of expertise. This project creates a trail assessment methodology that can be applied to a trail with limited funds. The final methodology was efficient, succinct, accurate, and simple to conduct. It uses a problem based methodology where every instance of degradation …

Airborne Lidar Acquisition, Post-Processing And Accuracy-Checking For A 3d Webgis Of Copan, Honduras, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Maria Grazia Spera, Michael Auer, Nicolas Billen, Lukas Loos, Laura Stelson, Markus Reindel

Department of Anthropology: Faculty Publications

Archaeological projects increasingly collect airborne LiDAR data to use as a remote sensing tool for survey and analysis. Publication possibilities for LiDAR datasets, however, are limited due to the large size and often proprietary nature of the data. Fortunately, web-based, geographic information systems (WebGIS) that can securely manage temporal and spatial data hold great promise as virtual research environments for working with and publishing LiDAR data. To test this and to obtain new data for archaeological research, in 2013, the MayaArch3D Project (www.mayaarch3d.org) collected LiDAR data for the archaeological site of Copan, Honduras. Results include: 1) more accurate archaeological maps, …

Computationally Inexpensive Landsat 8 Operational Land Imager (Oli) Pansharpening, Hankui Zhang, David P. Roy

GSCE Faculty Publications

Pansharpening algorithms fuse higher spatial resolution panchromatic with lower spatial resolution multispectral imagery to create higher spatial resolution multispectral images. The free-availability and systematic global acquisition of Landsat 8 data indicate an expected need for global coverage and so computationally efficient Landsat 8 pansharpening. This study adapts and evaluates the established, and relatively computationally inexpensive, Brovey and context adaptive Gram Schmidt component substitution (CS) pansharpening methods for application to the Landsat 8 15 m panchromatic and 30 m red, green, blue, and near-infrared bands. The intensity images used by these CS pansharpening methods are derived as a weighted linear combination …

The concentration of supermarkets in the City of Huntington has led to a service gap in the outlying census block groups of the study area. Supermarket access is concentrated in the City of Huntington and may provide a positive outcome for families living within the city. The study assesses the impact of the implementation of a supermarket shuttle on supermarket access within the study area, through spatial analysis of supermarkets, transportation networks, and census block groups. The transportation network data and census block …

Reaching The Water's Edge: Assessing Riverfront Accessibility In The Quad Cities Area, Lorraine Stamberger

Geography: Student Scholarship & Creative Works

In river towns across the United States, a slow transformation is taking place as aging and abandoned industrial infrastructure is being replaced by new riverfront uses. Consequently, the urban American riverfront has become a battleground, with municipalities, developers, and large corporations fighting over this contested land. Although riverfronts offer a wealth of benefits for the public such as therapeutic river views and abundant recreational opportunities, studies have shown that public interests and access are often overlooked in the waterfront development process. The purpose of this research is to understand the level of access people in the Quad Cities community have …
