Item type: Item , Zoning in Seattle(2018-05-17) Wettstein, Lily; Sawyer, KatlynThis poster discusses the history of multifamily and single family home zoning in Seattle since 1923 when the zoning of the city began. This poster uses historical maps of the city as well as a current map of zoning as it exists today. An analysis is done of family home zoning in Wallingford and Capitol Hill to compare development of two different neighborhoods and how it is connected to zoning policy.Item type: Item , Topography Changes of the University of Washington Bothell Campus(2018-05-17) Darwish-Elhaji, Safaa; Yang, MingyouThe City of Bothell provided historical topographical data of the University of Washington Bothell (UWB) campus for this group to analyze the changing landscape and elevation of the area. This poster analyzes topographical vector data of the UWB campus for the years 2000, 2008, and 2015. The data were collected by the City of Bothell using Orthoimagery and LiDAR data. Goals for this project included: 1) derive digital elevation models that most accurately represent the UWB campus topography using the Topo-to-Raster technique in an ArcMap environment and 2) compare changes in elevation over time. The intent is to account for the errors that may arise when interpolating three datasets that were collected using two different remote sensing techniques. A map algebra framework is used to compare changes in topography between 2000 and 2015. The campus has had several buildings and a new parking lot added in the time these data were collected, and this group expects to see the most changes in topography where there has been construction. Since the main UWB campus sits on a steep incline, this group expects to see erosion and the effects of compensating for this erosion, as having the most impact in shifting contour lines. Future work on this topic will include comparing vegetation coverage over the years and investigate how they relate to topographic and hydrological changes.Item type: Item , Stronger Communities, Healthier People(2018-05-17) Paine, ThomasThis poster looks at a suitability model, using ArcGIS Pro, for identifying the best places for community gardens. These gardens will be built on community members’ front lawns so that they can be readily available, especially in areas classified as food deserts. This poster focuses on Little Rock, Arkansas, as this is one of the most obese cities in the country. In addition to community gardens supplying healthy wholesome food to residents, it is also important to recognize that this activity provides neighbors the opportunity to actually get to know one another and helps build a stronger sense of community identity. This is a final project for Dr. Walter's course RE 370: Real Estate Data Modeling.Item type: Item , Rental Real Estate for Commuters(2018-05-17) Higgins, MitchellWestern Washington residents near the Seattle metropolitan area are running out of living options, and major cities near the Puget Sound are where many major employers are located. These employers were identified as Microsoft (Redmond), Boeing (Everett and Seattle), Amazon (Seattle), and the University of Washington (Seattle and Bothell). Although there are some vacancies in the city and surrounding area, price has driven many who are seeking to rent residential real estate to look outside of heavily urbanized areas. Some commuters who rent are doing so as they look for long term housing (buying) as they are often from out of state or even out of the country. Specified locations that proved to be consistently listed as undesirable were the cities of Everett, Redmond, and Seattle. Five metrics are used for a suitability analysis: Price, travel time, Schooling, crime, and population density.Item type: Item , China Linpan Landscape Ecology Assessment(2018-05-17) Wu, Shuang; Xu, FengyiThis study focuses on a unique agricultural landscape in Southwest China called Linpan. It has been used by the local residents for thousands of years and has been utilized for its high food productivity and high resiliency. However, during recent years of rapid urbanization in China, this landscape is under threat. Due to its uniqueness and outstanding ecological and social value, this talk analyzes how quickly this landscape is degrading, how to quantify the fragmentation of this landscape and what its relationship is to urbanization indicators such as road construction. Tools used include the GIS landscape metrics calculation package Fragstats.Item type: Item , Opportunity Index - King & Pierce Counties(2018-05-17) Acosta, MarvinThis poster examines the differences in the geography of opportunity between two major counties, King County and Pierce County, both located in Washington State. There are increasing rates of movement of individuals relocating from King County to Pierce County as a result of housing affordability pressures. This phenomenon led to the question of where opportunities were highest, and which county had higher opportunities overall.Item type: Item , Transit Oriented Development in the Palm Beaches(2018-05-17) Albee, Samuel JusticeWith the creation of the new Coastal Link Tri-Rail extension in South Florida, there is a large opportunity for the region to utilize space more efficiently and equitably. This project uses suitability analysis and GIS to examine and evaluate potential sites for strategic redevelopment and the construction of transit-oriented development. The South Florida area is largely dependent on car usage, even in the urban cores. The current commuter train is west of the most densely populated areas, however the new Coastal Link will run through the most densely populated areas, providing more connectivity within the region. Additionally, the new high-speed Brightline train will run on the same tracks, acting as an express service. With these new infrastructure projects, the traditionally sprawling South Florida has the opportunity to develop into a more sustainable and equitable region.Item type: Item , Remote Sensing(2018-05-17) Barton, IvanThe first Sentinel-2 satellite was sent to orbit in 2015 as part of the European Copernicus program. It provides free, high resolution Earth observation data on global scale, collecting an incredible amount of data (1.6 TB/orbit). In the past, image interpretation was done by human operators, but in the last few decades computer vision has played a significant role in mapping due to the increasing data volume. With object based image analysis (OBIA) the mapping quality could approach or even overtake the man-made maps with high resolution images. The first and most important step in OBIA is the image segmentation, wherein the image is taken apart into homogenous regions. The state of art image segmentation methods are not frequently used in satellite remote sensing. Most modern methods are data driven, which perform well in artificial environment, but fail in natural environment due to the lack of training data. Therefore the older, unsupervised image segmentation algorithms are preferred by users. There are several commercial and open source OBIA solutions for processing long time series in order to extract thematic information. However, all of them have strengths and weaknesses which limits their research and operational applications. To overcome this problem, we implemented a modified multiresolution image segmentation algorithm which could be utilized for Sentinel-2 data processed in High Performance Computing (HPC) environments.Item type: Item , Slides of 2018 UW GIS Symposium Lightning Talk Presentations(2018-05-17) Albertson, Ellie; Peterson, Hanna; Buschman, Victoria; Laidre, Kristin; Monroe, Michael; Parsons, Matthew; Flynn, Kian; Logsdon, Miles; Gaolach, CollenePowerPoint slides from the 2018 UW GIS Symposium Lightning Talk presentations on May 17, 2018.Item type: Item , Proceedings of the Second Annual UW GIS Symposium, May 17, 2018(2018-05-17) Parsons, Matthew; Flynn, Kian; Mundt, MadelineThe 2nd Annual University of Washington (UW) GIS Symposium was held on May 17, 2018 in the University of Washington Libraries’ Research Commons, an interdisciplinary space devoted to highlighting student research. This year’s symposium continued its mission of creating an opportunity for faculty, students, and staff across disciplines to come together and share their GIS-related research. [from Preface]
