Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert
Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert
Electronic Theses and Dissertations
Migration plays a key role in determining the health and success of cities, counties, and countries. It also plays a key role in determining the health and wellbeing of the individuals and families that undergo a migration event. This has led many scholars to map and study global migration patterns to understand how and why people move. While migration data are powerful, the origin-destination (O-D), tabular format of the data can be hard to interpret. To make O-D data more powerful, geographers can lean on computer cartography and new geovisualization techniques to help decision makers make sense of large, complex …
Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis
Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis
Graduate Theses and Dissertations
The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …
Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller
Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller
Geography ETDs
Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …
The Image From The Road: Towards Mapping The Phenomenological, Rachel Anna Smith Loerts
The Image From The Road: Towards Mapping The Phenomenological, Rachel Anna Smith Loerts
Graduate Theses and Dissertations
An area of focus, used in early and contemporary forms of cognitive geography research, is the ‘cognitive map’, a concept that suggests “that people hold a map-like database in their minds to which they can add and use to tackle geographical tasks”. Kevin Lynch, an urban planner in the 1960s, was an early adopter of the cognitive map approach to reveal spatial cognition, what or how people see their environment, specifically cognition of the urban environment. Lynch’s research aimed to develop empirical methods, to identify how people make spatial relationships. Contemporary tools like machine learning are now considered relevant for …
Increasing Accessibility For Map Readers With Acquired And Inherited Color Vision Deficiencies: A Re-Coloring Algorithm For Maps, Gretchen M. Culp
Increasing Accessibility For Map Readers With Acquired And Inherited Color Vision Deficiencies: A Re-Coloring Algorithm For Maps, Gretchen M. Culp
Dissertations, Theses, and Capstone Projects
Approximately 8% of the male population suffer from an inherited form of color vision deficiency (CVD). Age, diabetes, macular degeneration, cataracts and glaucoma result in eye defects including an acquired form of CVD. Inherited CVD is marked by a difficulty in discerning red from green, while acquired CVD is marked by a difficulty in discerning blue from green. A recent review of the cartographic literature revealed a deficit in studies on accessible maps for readers with the acquired form of CVD. In addition, research on accessible maps for readers with the inherited form of CVD was restricted to the design …
Mapping And Analyzing Historical Sanborn Maps Of San Luis Obispo From 1905 And 1950, Troy A. Lawson
Mapping And Analyzing Historical Sanborn Maps Of San Luis Obispo From 1905 And 1950, Troy A. Lawson
Social Sciences
This project was conducted to map, analyze, and determine historical changes in the city of San Luis Obispo, California. Sanborn maps from 1905 and 1950 were drawn showing streets, parcels, creeks, and buildings of the city. These publications had limited use because they were in a physical format without any geographic reference. Here, these maps were digitized into a GIS format to analyze building trends and identify cultural and historical buildings not on the City’s list of Historic and Culturally Contributing Buildings, as well as published online on the City of San Luis Obispo’s website and on ArcGIS Online. Additionally, …
Mapping Xenophobic Violence In South Africa: Modeling Spatial Relationships Between Group Grievances And Opportunities To Measure The Propensity For Xenophobic Violence, Eric Holder
Graduate Theses and Dissertations
Xenophobia can be defined as the hatred or fear of foreigners or strangers or of their politics or culture (Ngwane et al., 2008). This sentiment reached its tipping point in urban areas across the Republic of South Africa in May 2008 when mass, widespread and systematic attacks against African non-nationals took place across the country. Although previous research agrees on who played the various roles during this crisis event (Everatt, 2010), little research has been carried out to create a predictive model to assess where future violence could occur based on a set of conflict indicators. The purpose of this …
Topological Equivalence And Similarity In Multi-Representation Geographic Databases, Joao Argemiro De Carvalho Paiva
Topological Equivalence And Similarity In Multi-Representation Geographic Databases, Joao Argemiro De Carvalho Paiva
Electronic Theses and Dissertations
Geographic databases contain collections of spatial data representing the variety of views for the real world at a specific time. Depending on the resolution or scale of the spatial data, spatial objects may have different spatial dimensions, and they may be represented by point, linear, or polygonal features, or combination of them. The diversity of data that are collected over the same area, often from different sources, imposes a question of how to integrate and to keep them consistent in order to provide correct answers for spatial queries. This thesis is concerned with the development of a tool to check …
