Provenance Tracking In A Commons Of Geographic Data, David B. Mccurry

Electronic Theses and Dissertations

Advancement in digital archiving technologies provides researchers with a multitude of methods for sharing their research and data digitally with others. However, when acquiring data from others directly or indirectly the law often imposes an assumption of copyright in the dataset acquired. This creates a difficult legal situation affecting future use and creation of derivative works from the data. A digital commons may be defined as a shared resource in which creators of contributed materials (data) grant a legal right for all others to use the material under the provisions of an open-access license. This thesis hypothesizes that an approach …

Combining Geospatial And Temporal Ontologies, Kripa Joshi

Electronic Theses and Dissertations

Publicly available ontologies are growing in number at present. These ontologies describe entities in a domain and the relations among these entities. This thesis describes a method to automatically combine a pair of orthogonal ontologies using cross products. A geospatial ontology and a temporal ontology are combined in this work. Computing the cross product of the geospatial and the temporal ontologies gives a complete set of pairwise combination of terms from the two ontologies. This method offers researchers the benefit of using ontologies that are already existing and available rather than building new ontologies for areas outside their scope of …

Gis Analysis For Abu Dhabi Schools, Shaima Hassan Hammadi

Theses

Geographic Information Systems (GIS) have become an indispensable tool in many fields of study and research. GIS is useful for choosing sites, targeting market segments, planning infrastructure facilities and responding to emergencies. GIS is internationally used for the educational sector in different aspects such as planning schools allocation and managing educational resources. This thesis investigated the spatial distribution of schools in Abu Dhabi with respect to population density and service areas, generated prospective locations for constructing new schools based on the current and future demand using multi-criteria decision rules, developed a road network system that helps in finding shortest and …

Semantic Interoperability Of Geospatial Ontologies: A Model-Theoretic Analysis, James A. Farrugia

Electronic Theses and Dissertations

People sometimes misunderstand each other, even when they use the same language to communicate. Often these misunderstandings happen when people use the same words to mean different things, in effect disagreeing about meanings. This thesis investigates such disagreements about meaning, considering them to be issues of semantic interoperability. This thesis explores semantic interoperability via a particular formal framework used to specify people’s conceptualizations of a given domain. This framework is called an ‘ontology,’ which is a collection of data and axioms written in a logical language equipped with a modeltheoretic semantics. The domain under consideration is the geospatial domain. Specifically, …

Geospatial Informational Security Risks And Concerns Of The U.S. Air Force Geobase Program, Scott A. Bryant

Theses and Dissertations

Technological advancements such as Geospatial Information Systems (GIS) and the Internet have made it easier and affordable to share information, which enables complex and time sensitive decisions to be made with higher confidence. Further, advancements in information technology have dramatically increased the ability to store, manage, integrate, and correlate larger amounts of data to improve operational efficiency. However, the same technologies that enable increased productivity also provide increased capabilities to those wishing to do harm. Today’s military leaders are faced with the challenge of deciding how to make geospatial information collected on military installations and organizations available to authorized communities …

Internet Protocol Geolocation: Development Of A Delay-Based Hybrid Methodology For Locating The Geographic Location Of A Network Node, John M. Roehl

Theses and Dissertations

Internet Protocol Geolocation (IP Geolocation), the process of determining the approximate geographic location of an IP addressable node, has proven useful in a wide variety of commercial applications. Commercial applications of IP Geolocation include market research, redirection for performance enhancement, restricting content, and combating fraud. The potential for military applications include securing remote access via geographic authentication, intelligence collection, and cyber attack attribution. IP Geolocation methods can be divided into three basic categories based upon what information is used to determine the geographic location of the given IP address: 1) Information contained in databases, 2) information that is leaked during …

Scotland: The New Melting Pot?, Alexandria Rovatsos

Theses, Dissertations and Capstones

Discussion of population issues increasingly centers on the low fertility rates common in much of the developed world. As a result of these low fertility rates and increased longevity, populations across much of Europe are getting older and in many cases declining in size. In response, governments with low fertility rates have implemented a variety of policies to maintain their population. While many countries have tried to boost fertility, Scotland had opted for a less popular approach, i.e. pro-immigration. This thesis focuses on Scotland and the policy implemented by the government to combat low fertility.

Estimation Of The Effects Of Vegetation On Local Climate Using Gis And Remote Sensing Data, Won Hoi Hwang

Theses, Dissertations and Capstones

As one of the effective methods to control urban temperatures, the effects of trees and other vegetation have come into focus. Geographic Information System (GIS) and remote sensing data, Digital Orthophoto Quarter-Quadrangle (DOQQ) and Landsat Thematic Mapper (Landsat TM), have been applied in this study to analyze the UHI. The effect of road-side trees on local micro-climate was examined with in-situ temperature measurement and simulated shade. Regression analyses revealed significant negative slopes for all time periods. This trend continued throughout the entire night until sunrise the next morning. The relationship between thermal patterns and vegetation distributions was investigated using the …

An Analytical Overview Of The Factors Influencing Housing Accessibility Of Bangladeshi Immigrants In Kitchener-Waterloo, Farzana Afreen Propa

Theses and Dissertations (Comprehensive)

This study explores Bangladeshi immigrants’ settlement experiences in Kitchener-Waterloo (K-W) and alyses their housing history, housing search process, barriers and discrimination in accessing housing in the area. It reveals the factors that influence Bangladeshi immigrants housing accessibility in K-W. It also summarises recommendations to support and improve their housing situation. Qualitative research methods were used to collect and document the findings of the research.

The study findings reveal Bangladeshi immigrant households in K-W have comparaitvely higher levels of education compared to mainstream population and better employment condition compared to other Bangladeshi immigrants living in Toronto or Montreal. Many of these …
