Accuracy Evaluation Of The Canadian Openstreetmap Road Networks, Hongyu Zhang, Jacek Malczewski 2018 The University of Western Ontario

Accuracy Evaluation Of The Canadian Openstreetmap Road Networks, Hongyu Zhang, Jacek Malczewski

International Journal of Geospatial and Environmental Research

Volunteered geographic information (VGI) has been applied in many fields such as participatory planning, humanitarian relief and crisis management. One of the reasons for popularity of VGI is its cost-effectiveness. However, the coverage and accuracy of VGI cannot be guaranteed. The issue of geospatial data quality in the OpenStreetMap (OSM) project has become a trending research topic because of the large size of the dataset and the multiple channels of data access. This paper focuses on a national study of the Canadian OSM road network data for the assessment of completeness, positional accuracy, attribute accuracy, semantic accuracy and lineage. The ...


Temporal And Spatiotemporal Investigation Of Tourist Attraction Visit Sentiment On Twitter, Jose J. Padilla, Hamdi Kavak, Christopher J. Lynch, Ross J. Gore, Saikou Y. Diallo 2018 Old Dominion University

Temporal And Spatiotemporal Investigation Of Tourist Attraction Visit Sentiment On Twitter, Jose J. Padilla, Hamdi Kavak, Christopher J. Lynch, Ross J. Gore, Saikou Y. Diallo

VMASC Publications

In this paper, we propose a sentiment-based approach to investigate the temporal and spatiotemporal effects on tourists' emotions when visiting a city's tourist destinations. Our approach consists of four steps: data collection and preprocessing from social media; visitor origin identification; visit sentiment identification; and temporal and spatiotemporal analysis. The temporal and spatiotemporal dimensions include day of the year, season of the year, day of the week, location sentiment progression, enjoyment measure, and multi-location sentiment progression. We apply this approach to the city of Chicago using over eight million tweets. Results show that seasonal weather, as well as special days ...


The Impacts Of Green Spaces On Crime In New York City, Matthew Edward Iannone Jr. 2018 Fordham University

The Impacts Of Green Spaces On Crime In New York City, Matthew Edward Iannone Jr.

Student Theses 2015-Present

From the early 1960s through the mid-1990s, crime in New York City ran rampant. With a gradually dwindling police during this time, a high unemployment rate, and an rapidly increasing metropolitan population, crime peaked in the early 1990s, with the murder rate hitting a record-high of 2,245 in 1990. When Mayor Rudy Giuliani took office in 1994 and appoint Bill Bratton as the NYPD police commissioner, these rates immediately plunged. Numerous factors may have contributed to this sudden decline in crime: the police force grew significantly through the 1990s, more criminals were placed and held in prison, and the ...

The Devil You Don’T Know: A Spatial Analysis Of Crime At Newark’S Prudential Center On Hockey Game Days, Justin Kurland, Eric Piza 2018 Institute for Security and Crime Science - University of Waikato

The Devil You Don’T Know: A Spatial Analysis Of Crime At Newark’S Prudential Center On Hockey Game Days, Justin Kurland, Eric Piza

Journal of Sport Safety and Security

Inspired by empirical research on spatial crime patterns in and around sports venues in the United Kingdom, this paper sought to measure the criminogenic extent of 216 hockey games that took place at the Prudential Center in Newark, NJ between 2007-2016. Do games generate patterns of crime in the areas beyond the arena, and if so, for what type of crime and how far? Police-recorded data for Newark are examined using a variety of exploratory methods and non-parametric permutation tests to visualize differences in crime patterns between game and non-game days across all of Newark and the downtown area. Change ...

Out-Group Threat Or Inter-Group Contact Theory? Out-Group Attitudes And Interaction In Times Of Diversity Growth, Annette Jacoby 2018 The Graduate Center, City University of New York

Out-Group Threat Or Inter-Group Contact Theory? Out-Group Attitudes And Interaction In Times Of Diversity Growth, Annette Jacoby

All Dissertations, Theses, and Capstone Projects

Much attention has been devoted to the presumed negative effect of diversity growth on various dimensions of attitudes and interaction between different racial and ethnic groups. However, whether the claims hold true is unclear- there is a considerable controversy over the impact of changing diversity on societal behavior. With ongoing migration, the United States are becoming more and more ethnically diverse but a sound debate on racial and ethnic composition and its consequences for inter-group interactions and attitudes towards others has not yet been possible due to a lack of causally-oriented panel studies.

In this study, two important features are ...

GSCE Faculty Publications

A consistent dataset delineating and characterizing changes in urban environments will be valuable for socioeconomic and environmental research and for sustainable urban development. Remotely sensed data have been long used to map urban extent and infrastructure at various spatial and spectral resolutions. Although many datasets and approaches have been tried, there is not yet a universal way to map urban extents across the world. Here we combined a microwave scatterometer (QuikSCAT) dataset at ~1 km posting with percent impervious surface area (%ISA) data from the National Land Cover Dataset (NLCD) that was generated from Landsat data, and ambient population data ...

Assessment Of Spatiotemporal Fusion Algorithms For Planet And Worldview Images, Chiman Kwan, Xiaolin Zhu, Feng Gao, Bryan Chou, Daniel Perez, Jinag Li, Yuzhong Shen, Krzysztof Koperski, Giovanni Marchisio

Electrical & Computer Engineering Faculty Publications

Although Worldview-2 (WV) images (non-pansharpened) have 2-m resolution, the re-visit times for the same areas may be seven days or more. In contrast, Planet images are collected using small satellites that can cover the whole Earth almost daily. However, the resolution of Planet images is 3.125 m. It would be ideal to fuse these two satellites images to generate high spatial resolution (2 m) and high temporal resolution (1 or 2 days) images for applications such as damage assessment, border monitoring, etc. that require quick decisions. In this paper, we evaluate three approaches to fusing Worldview (WV) and Planet ...


Accounting For Spatial Autocorrelation In Modeling The Distribution Of Water Quality Variables, Lorrayne Miralha 2018 University of Kentucky

Accounting For Spatial Autocorrelation In Modeling The Distribution Of Water Quality Variables, Lorrayne Miralha

Theses and Dissertations--Geography

Several studies in hydrology have reported differences in outcomes between models in which spatial autocorrelation (SAC) is accounted for and those in which SAC is not. However, the capacity to predict the magnitude of such differences is still ambiguous. In this thesis, I hypothesized that SAC, inherently possessed by a response variable, influences spatial modeling outcomes. I selected ten watersheds in the USA and analyzed them to determine whether water quality variables with higher Moran’s I values undergo greater increases in the coefficient of determination (R²) and greater decreases in residual SAC (rSAC) after spatial modeling. I compared non-spatial ...

Modeling The In-State Geographic Market Changes Of South Dakota Public University Enrollments, 2006 To 2015, John Green 2018 South Dakota State University

Modeling The In-State Geographic Market Changes Of South Dakota Public University Enrollments, 2006 To 2015, John Green

Electronic Theses and Dissertations

The spatial nature of how high school students choose a college has become an integral part of the recruitment process at universities across the country. In South Dakota, the impact of distance on enrollment at state operated institutions influences the geographic footprint of each university. Between 2006 and 2015, the nature of those enrollment numbers and geographic footprints changed within the state, creating enrollment stagnation or decline at state run institutions. This research paper addresses the geographic nature of those enrollment declines, models the college enrollment decision of students in the state, and applies those findings towards potential enrollment projections ...
