A Gis Analysis To Identify Historical, Contemporary, And Spatial Housing Discrimination In Denver, Colorado, Ian Sharkey
A Gis Analysis To Identify Historical, Contemporary, And Spatial Housing Discrimination In Denver, Colorado, Ian Sharkey
Geography and the Environment: Graduate Student Capstones
This study analyzes the relationship between housing discrimination and equity within the City of Denver. This study creates a discrimination index by combining (1) historical Discrimination, (2) contemporary segregation, and (3) housing inequity data into an index to compare the Denver Department of Health and the Environment (DDPHE) 2020 equity index using a local bivariate analysis. This study found a negative linear relationship between the created and Denver equity indexes. The variables used for the discrimination index can explain some of the relationships, but future studies should use more variables for a discrimination index.
Using Gis To Identify Barriers To Access On The Rtd W Line In Denver, Colorado, Tristan Johnson
Using Gis To Identify Barriers To Access On The Rtd W Line In Denver, Colorado, Tristan Johnson
Geography and the Environment: Graduate Student Capstones
Denver, Colorado has a long history of public transportation usage beginning with horse-drawn streetcars in 1871. As the automobile began to flourish however, the use of public transportation has languished. In 2013, the W light rail line opened serving the West Denver area. As Denver has moved toward a more transit-oriented growth model, this rail line can create a more vibrant future. Using GIS, a better understanding of the barriers to access for light rail travel is obtained and considering key variables outputs are created to assist policy makers in utilizing the W line. By using GIS to address population …
Modeling Vegetation Cover At Mount St Helens Using Highly Correlated Vegetation Indices, Sara Livingston
Modeling Vegetation Cover At Mount St Helens Using Highly Correlated Vegetation Indices, Sara Livingston
Geography and the Environment: Graduate Student Capstones
The eruption of Mount St. Helens in 1980 devastated the landscape and obliterated all ground vegetation within a 620 km2 blast zone radius. The destructive forces of the lateral blast, debris avalanche, tephra plume, and lahar flow created a complex mosaic of disturbance zones, that subsequently yielded various rates of landscape recovery. Remote sensing is an efficient method for monitoring landscape-scale changes by recording the distinct spectral reflectance of vegetation. Based on statistically significant correlations between Vegetation Indices and vegetation parameters, an empirical model can be developed for vegetation cover predictions. This capstone analysis found that NDVI holds the strongest …
Analyzing The Production And Use Of Fossil Fuels: A Case For Data Mining And Gis, Alejandro Conde
Analyzing The Production And Use Of Fossil Fuels: A Case For Data Mining And Gis, Alejandro Conde
Geography and the Environment: Graduate Student Capstones
As technology progresses and data grows both larger and more complex, techniques are being developed to keep up with the exponential growth of information. The term “data mining” is a blanket term used to describe an approach to find anomalies and correlations in a large dataset. This approach involves leveraging data mining software to manipulate and prepare data, apply statistics to quantify trends and characteristics in the data from a high level, and potentially apply advanced techniques like machine learning to identify patterns that wouldn’t be apparent otherwise. In this case study, data mining aided a GIS in displaying substantial …
Detecting And Visualizing Observation Hot-Spots In Massive Volunteer-Contributed Geographic Data Across Spatial Scales Using Gpu-Accelerated Kernel Density Estimation, Guiming Zhang
Geography and the Environment: Faculty Scholarship
Volunteer-contributed geographic data (VGI) is an important source of geospatial big data that support research and applications. A major concern on VGI data quality is that the underlying observation processes are inherently biased. Detecting observation hot-spots thus helps better understand the bias. Enabled by the parallel kernel density estimation (KDE) computational tool that can run on multiple GPUs (graphics processing units), this study conducted point pattern analyses on tens of millions of iNaturalist observations to detect and visualize volunteers’ observation hot-spots across spatial scales. It was achieved by setting varying KDE bandwidths in accordance with the spatial scales at which …
Bicycles And Transit: Weather Or Not: A Study On The Effect Of Weather And Air Quality On Bicycle-Transit, Bicycle, Rail Transit Counts In Denver, Christiana M. Fairfield
Bicycles And Transit: Weather Or Not: A Study On The Effect Of Weather And Air Quality On Bicycle-Transit, Bicycle, Rail Transit Counts In Denver, Christiana M. Fairfield
Electronic Theses and Dissertations
The movement of people and goods within metropolitan areas is critically important to the operational efficiency and functionality of cities. This study explores the influence of local weather conditions and the air quality index on bicycle-transit user in Denver, Colorado. Based on bicycle-transit having two key components, bicycle and transit, the effect of local weather conditions and the air quality index is also explored with bicycle use and rail-transit usage. Key findings include: (1) the most significant variable across all three modes is temperature, (2) for bicycle-transit and bicycle use, there is a steady increase in ridership as temperatures increase …
Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz
Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz
Electronic Theses and Dissertations
Understanding youth relationships with nature—what nature is, where nature is located, and why nature is meaningful—is important for a range of contemporary issues, from promoting health and well-being to advancing a sustainable future. Relationships with nature are profoundly influenced by the lived experiences of youth, as they form social connections, have fun, learn, and go about their lives across an array of places—residences, schools, trip destinations, and places in between. One key to exploring youth relationships with nature, therefore, is engaging youth to document their experiences of nature in relation to specific places and developing methods that support them to …
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 …
Care Infrastructure Accessibility And The Gender Wage Gap – A Way To Improve Women’S Ability To Equitably Engage In The Paid Labor Market?, Julia Schinnenburg
Care Infrastructure Accessibility And The Gender Wage Gap – A Way To Improve Women’S Ability To Equitably Engage In The Paid Labor Market?, Julia Schinnenburg
Electronic Theses and Dissertations
World-wide, women are less integrated into the labor force than men and if they are, they earn considerably less on average. This unequal treatment of women results in negative consequences for all members of society, as it harms women’s financial realities and also affects women’s care receivers due to a lack of resources that women can spend on their care giving. The research presented analyses how much the institution of better accessible care infrastructure could improve women’s ability to work for pay and decrease their daily workloads. The extent to which improved care infrastructure accessibility affects women’s lives is determined …
