A Parallel Computing Approach To Fast Geostatistical Areal Interpolation, Qingfeng Guan, Phaedon Kyriakidis, Michael Goodchild 2011 University of Nebraska - Lincoln

A Parallel Computing Approach To Fast Geostatistical Areal Interpolation, Qingfeng Guan, Phaedon Kyriakidis, Michael Goodchild

Geography Program: Faculty Publications

Areal interpolation is the procedure of using known attribute values at a set of (source) areal units to predict unknown attribute values at another set of (target) units. Geostatistical areal interpolation employs spatial prediction algorithms, i.e., variants of Kriging, which explicitly incorporate spatial autocorrelation and scale differences between source and target units in the interpolation endeavor. When all the available source measurements are used for interpolation, i.e., when a global search neighborhood is adopted, geostatistical areal interpolation is extremely computationally intensive. Interpolation in this case requires huge memory space and massive computing power, even with the dramatic improvement introduced by …

Social Disorganization And Sex Offenders In Minneapolis, Mn: A Socio-Spatial Analysis, Joseph Koncur

All Graduate Theses, Dissertations, and Other Capstone Projects

Using a combination of techniques stemming from the spatial analysis approach of Geography, structural-functionalist theory in Sociology, and an ecological perspective of Criminology, this thesis addresses where sex offenders reside and why. Analyses were performed using the twin cities of Minneapolis and St. Paul, Minnesota as a typical urban setting. The study fuses multiple disciplines work on the complex social problem of released risk level III sex offender management in a spatially-conscious, micro-scale analysis attempting to understand the distribution of released offenders and the relevance of social disorganization theory in explaining their distribution. Socio-economic status and family disruption are tested …


Minnesota River Basin Flood Mapping And Impact Assessment, Willy J. Mekeel 2011 Minnesota State University - Mankato

Minnesota River Basin Flood Mapping And Impact Assessment, Willy J. Mekeel

All Graduate Theses, Dissertations, and Other Capstone Projects

South Central Minnesota has experienced frequent flooding in the past because of the relatively flat topography, low elevation, and large amounts of snow melt in the spring. When these events happen, there is a large economic impact and potential health hazards to residents of the area. Having up-to-date flood zone maps can help residents be better prepared for emergency situations. Using Geographic Information Science (GIS), flood zone maps can be updated frequently in a more time efficient and inexpensive manner. Using a 30-meter digital elevation model (DEM) Compound Topographic Index (CTI) and Stream Power Index (SPI) layers were calculated for …


Development Of A Web-Based Geographic Information System For Arctic Science, George Walker Johnson 2011 University of Texas at El Paso

Development Of A Web-Based Geographic Information System For Arctic Science, George Walker Johnson

Open Access Theses & Dissertations

Environmental science is a large field of study that requires the acquisition of data for decision making in solving environmental issues. Leveraging desktop geographic information systems (GIS) and web-based GIS (WebGIS) systems for assisting in the problem solving processes can benefit both the research community and policy makers for decision making activities. Ensuring interoperability between desktop, web, and server GIS is essential for maximizing access, sharing and manipulation of data. Interoperability is maximized through the adoption of best practices, use of open standards, and utilization of Spatial Data Infrastructures (SDI). While many of the interoperability challenges such as infrastructure, data …

Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green 2011 Minnesota State University - Mankato

Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose for studying exurbanization is to evaluate the spatial spread of metropolitan areas into their immediate hinterlands through remote sensing satellite imagery. This includes addressing scholar's inability to define exurbia, along with plausible reasons people move into exurbia. In addition, determination will include consideration on the possibility that exurbia has become an extension of America's growing and increasingly independent suburbia or; recognize that exurbia exists, but within various geographic locations. In return to the former, an analytical approach was taken to investigate scholar's inability to provide a definition to this phenomena; as well as inconsistent results on the push …


Gis Maps And The Amazon Borderlands, David S. Salisbury 2011 University of Richmond

Gis Maps And The Amazon Borderlands, David S. Salisbury

Geography and the Environment Faculty Publications

With training, GIS can be used by all sectors of Latin American society and is the mapping tool of choice for institutions ranging from the Inter-American Development Bank to remote communities in the Amazon rain forest. Geographic information systems are thus a tool of the powerful and the marginalized and the official and the unofficial. [...] In this chapter, we see how GIS maps can improve our ability to analyze conflict over resources and allow additional participation in the process of mapping, but we also confront some of the many political and technical challenges that must be overcome to construct …


Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal 2011 University at Albany, State University of New York

Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal

Legacy Theses & Dissertations (2009 - 2024)

This thesis presents a brief overview of quantitative spatial analysis in archaeology with a discussion of the theoretical and methodological issues involved, and describes a set of methods for using Geographic Information System (GIS) software and spatial statistics for the assessment of archaeological resources. GIS has become a nearly ubiquitous and indispensable tool in many fields of resource management including archaeology. It is, however, applied by archaeologists most frequently for basic cartographic representations, large-scale regional analyses, or resource management data warehousing. Such applications underutilize the scale-independence of GIS, which is equally potent for intra-project data assessment. This thesis describes a …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein 2011 University of South Florida

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

Road-Based Landscape Metrics For Quantifying Habitat Fragmentation, Rebecca Whitehead Loraamm 2011 University of South Florida

Road-Based Landscape Metrics For Quantifying Habitat Fragmentation, Rebecca Whitehead Loraamm

USF Tampa Graduate Theses and Dissertations

Landscape metrics measure the composition and configuration of habitats within landscapes; often the goal is to measure fragmentation. While a variety of existing metrics characterize the connectivity and contiguity of habitat patches, most do not explicitly consider the fragmenting effects of roads in their formulations. This research develops a set of new landscape metrics that explicitly quantify how roads disconnect and break apart habitat patches. This research introduces the following four metrics to consider the fragmenting effects of transportation networks: (1) Number of Connected Patches, a measure of connectivity; (2) Euclidean Nearest Neighbor-Roads, a measure of proximity; (3) Road Density, …


The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza 2011 University of South Florida

The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …


An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez 2011 University of Texas at El Paso

An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez

Open Access Theses & Dissertations

Crustal rupture structures reactivated in the course of the tectonic history of northern Mexico are the surface expressions of planes of weakness, in the form of simple or composite rectilinear features or slightly curved, defined as lineaments. Unless otherwise defined as strike-slip faults, lineaments are part of parallel and sub-parallel oblique convergent or oblique divergent tectonic zones cross cutting the Sierra Madre Occidental and northern Mexico, in a NW trend. These shear zones are the response to the oblique subduction of the Farallon plate beneath North America.

Kinematic analysis of five selected sites in northern Mexico, three basins and two …


Integrating Custom Mapping And Structure Preplanning With Gis For Emergency Responders, Zachary M. Hittie 2010 James Madison University

Integrating Custom Mapping And Structure Preplanning With Gis For Emergency Responders, Zachary M. Hittie

Masters Theses, 2010-2019

Accurate information can mean the difference between life and death for emergency responders and the people they serve. At the Harrisonburg Fire Department, laptops with customized databases for street maps and building preplans are one source of information for first responders. Another available resource is a Geographic Information System for the City of Harrisonburg and Rockingham County. However, ESRI’s ArcGIS® software is far from user-friendly in a mobile atmosphere. The objective of this research is to develop new software that integrates the ArcGIS® tool suite with custom street map files and structure preplan databases into a single application on a …
