Finding, Organizing, And Creating Spatial Data, Sarah Watson 2017 University of Kentucky

Finding, Organizing, And Creating Spatial Data, Sarah Watson

Research Data and Scholarly Communications Committee Workshops

To produce a compelling and attractive map, it is necessary to have quality data. However, finding quality data and using it to prepare maps can be quite challenging. This workshop will begin with a review of different types of spatial data, how to access it, and strategies for understanding and organizing it. We will then focus on creating our own data by georeferencing scanned paper maps. Georeferencing involves assigning geographic coordinates to images (e.g., maps, aerial photos) that lack a defined coordinate system. Georeferencing helps us locate where an image is located in the world so we can effectively ...

P01. Examining The Community Food Environments For Elementary School-Aged Children In The City Of London And Middlesex County, Ontario, Catherine Dubreck

Western Research Forum

Background: Childhood obesity is a growing public health issue. In Canada, one in four children/youth are overweight or obese. Research suggests diet plays a crucial role in childhood obesity, and that prevalence rates of overweight or obesity among children in a neighborhood may relate to area socioeconomic characteristics and other environmental factors. The community nutrition environment (e.g., the type, location, and accessibility of food outlets) can influence dietary habits.

Methods: Using ArcGIS, public and private elementary school addresses were geocoded, food outlets were mapped, and both junk food outlet density and the modified retail food environment index were ...

3d Tool Evaluation And Workflow For An Ecological Approach To Visualizing Ancient Socio-Environmental Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto, Shona Sanford-Long, Jack Kerby-Miller 2017 University of Nebraska-Lincoln

3d Tool Evaluation And Workflow For An Ecological Approach To Visualizing Ancient Socio-Environmental Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto, Shona Sanford-Long, Jack Kerby-Miller

Anthropology Faculty Publications

Architectural reconstructions are the centerpieces of ancient landscape visualization. When present, vegetation is relegated to the background, resulting in underutilized plant data—an integral data source for archaeological interpretation—thus limiting the capacity to take advantage of 3D visualization for studying ancient socio-environmental dynamics. Our long-term objective is to develop methods of 3D landscape visualization that have value for examining changes in land use and settlement patterns. To begin to work toward this objective, we have (1) identified 3D tools and techniques for vegetation modeling and landscape visualization, (2) evaluated the pros and cons of these tools, (3) investigated biological ...

Journal of Spatial Information Science

This paper presents a methodology of mapping population-centric social, infrastructural, and environmental metrics at neighborhood scale. This methodology extends traditional survey analysis methods to create cartographic products useful in agent-based modeling and geographic information analysis. It utilizes and synthesizes survey microdata, sub-upazila attributes, land use information, and ground truth locations of attributes to create neighborhood scale multi-attribute maps. Monte Carlo methods are employed to combine any number of survey responses to stochastically weight survey cases and to simulate survey cases' locations in a study area. Through such Monte Carlo methods, known errors from each of the input sources can be ...

Trajectory Data Mining: A Review Of Methods And Applications, Jean Damascène Mazimpaka, Sabine Timpf 2016 University of Augsburg

Trajectory Data Mining: A Review Of Methods And Applications, Jean Damascène Mazimpaka, Sabine Timpf

Journal of Spatial Information Science

The increasing use of location-aware devices has led to an increasing availability of trajectory data. As a result, researchers devoted their efforts to developing analysis methods including different data mining methods for trajectories. However, the research in this direction has so far produced mostly isolated studies and we still lack an integrated view of problems in applications of trajectory mining that were solved, the methods used to solve them, and applications using the obtained solutions. In this paper, we first discuss generic methods of trajectory mining and the relationships between them. Then, we discuss and classify application problems that were ...


Enhancing Building Footprints With Squaring Operations, Imran Lokhat, Guillaume Touya 2016 IGN - COGIT team

Enhancing Building Footprints With Squaring Operations, Imran Lokhat, Guillaume Touya

Journal of Spatial Information Science

Whatever the data source, or the capture process, the creation of a building footprint in a geographical dataset is error prone. Building footprints are designed with square angles, but once in a geographical dataset, the angles may not be exactly square. The almost-square angles blur the legibility of the footprints when displayed on maps, but might also be propagated in further applications based on the footprints, e.g., 3D city model construction. This paper proposes two new methods to square such buildings: a simple one, and a more complex one based on nonlinear least squares. The latter squares right and ...


Mixed Map Labeling, Maarten Löffler, Martin Nöllenburg, Frank Staals 2016 Utrecht University

Mixed Map Labeling, Maarten Löffler, Martin Nöllenburg, Frank Staals

Journal of Spatial Information Science

Point feature map labeling is a geometric visualization problem, in which a set of input points must be labeled with a set of disjoint rectangles (the bounding boxes of the label texts). It is predominantly motivated by label placement in maps but it also has other visualization applications. Typically, labeling models either use internal labels, which must touch their feature point, or external (boundary) labels, which are placed outside the input image and which are connected to their feature points by crossing-free leader lines. In this paper we study polynomial-time algorithms for maximizing the number of internal labels in a ...

Spatial Distribution Of High Obesity Rates In South Carolina, Tom Bennett 2016 Furman University

Spatial Distribution Of High Obesity Rates In South Carolina, Tom Bennett

Earth and Environmental Sciences Presentations

In 2015, the rate of adult obesity in South Carolina was nearly 32%, which places South Carolina as the 13th worst state when it comes to the prevalence of adult obesity. Along with overall rates of adult obesity, South Carolina has the 8th highest high school student obesity rate with 16.3% of high school students being obese. These statistics are troubling because obesity is a primary cause of Type II Diabetes, high blood pressure, and many other negative health effects. These health care issues then affect supply and demand for health care, advertising, physical exercise, and many other market ...


Mapping Trends In Bike Theft On Furman Campus From 2001 To 2016, Tindall Ouverson 2016 Furman University

Mapping Trends In Bike Theft On Furman Campus From 2001 To 2016, Tindall Ouverson

Earth and Environmental Sciences Presentations

The Furman University Police Department categorizes bike thefts as "bike larcenies" in their reporting system. However, most bike thefts on a college campus are not for monetary gain but as a means of transportation for opportunistic students. Though the goal of student bike thieves may be to get to class on time, the United States Department of Justice classifies them as "joyriders". Campus bike theft is a concern because it results in a monetary loss for students.


Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler 2016 Furman University

Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler

Earth and Environmental Sciences Presentations

Looking at the entire soundscape and studying its spatial variability can often give us important information about the health of the ecosystem. However, most previous studies only measure sound intensity, and are therefore limited in their depiction of the soundscape. Another tool for mapping soundscapes is SPreAD-GIS. This tool models sound propagation in an area. However, previous studies have only used it to evaluate the effects of noise pollution, but not applied it towards depicting the soundscape as a whole. I mapped the soundscape of Furman University’s campus using sound intensity as well as many different soundscape indices in ...


The Impact Of Organic Farms: Biodiversity And Climate Change Resilience In The Southeast, Josie Newton 2016 Furman University

The Impact Of Organic Farms: Biodiversity And Climate Change Resilience In The Southeast, Josie Newton

Earth and Environmental Sciences Presentations

Resilience to climate change serves as an indicator of the effectiveness of organic farming practices. Resilience means that an area is able to return to a stable state after a disturbance. In this context, it means that the area is able to function regularly even in the face of climate change, an instance that affects species health and biodiversity. By mapping the locations of organic farms across the southeastern United States along with the resilience scores of areas as evaluated by The Nature Conservancy and comparing this map to farm locations and biodiversity measures, we are able to determine the ...

Lgbtq+ Affirming Locations Of Greenville County, C.J. Lane

Earth and Environmental Sciences Presentations

This project explores the LGBTQ+ Affirming Locations of Greenville county. An LGBTQ+ affirming location is best summarized by this response, “It's a comfortable and welcoming place where it doesn't only feel like LGBT+ people are just being tolerated”. This response was taken from a survey I sent out to LGBTQ+ Groups in the Greenville area and shows why it is important to identify locations in the Greenville county area. With people coming out and looking for support it is important for to know where they will not be discriminated against. The goal is to make a viewable map ...


Mapping The Impact Of Intensive Rotational Grazing On Soil Fertility Over Time On Greenbrier Farms In Pickens County, South Carolina, Emily Kirby 2016 Furman University

Mapping The Impact Of Intensive Rotational Grazing On Soil Fertility Over Time On Greenbrier Farms In Pickens County, South Carolina, Emily Kirby

Earth and Environmental Sciences Presentations

Intensive rotational grazing (IRG) is a management technique that involves a more intentional management approach which includes increased paddock numbers, shorter grazing periods, larger livestock presence per acre, and longer periods of rest on pastures. Potential advantages of this management technique include improved forage quality, greater yield, decreased erosion, stable production during adverse growing condition, and improved soil fertility. This study collects and analyzes data to understand the impact of rotational grazing on soil fertility as measured by SOC (soil organic carbon) and SON (soil organic nitrogen) on Greenbrier Farms in Easley, South Carolina. This study analyzes the transition from ...


Habitat Quality Modeling For Bird Species At Furman University, Emma Cook 2016 Furman University

Habitat Quality Modeling For Bird Species At Furman University, Emma Cook

Earth and Environmental Sciences Presentations

In rapidly urbanizing areas, such as Greenville County in Upstate South Carolina, it is important to study habitat use and quality across land cover types in order to maximize conservation. Habitat fragmentation is a threat to many species of birds in areas with increasing development, especially those species that utilize larger forest patches for nesting and foraging. While land cover type and patch size are extremely important factors in determining habitat quality for birds, recent research has shown that the matrix of surrounding landscape proves to be very important as well. The landscape matrix, sometimes called landscape mosaic, considers the ...


Examining The Active Transportation - Built Environment Relationship In London, Ontario, Douglas M. Rivet 2016 The University of Western Ontario

Examining The Active Transportation - Built Environment Relationship In London, Ontario, Douglas M. Rivet

Electronic Thesis and Dissertation Repository

Research on the relationship between the built environment and active transportation has accelerated and expanded over the past 20 years. This growth is in large part due to continuing evidence of rising rates in obesity and Type-2 diabetes that coincides with decreasing rates of physical activity across all ages in the post-industrial world. Walking more is a simple solution to increasing rates of physical activity. While for most people walking is possible throughout the day, there has been a decrease in the use of walking as a means of transportation. This study examines environmental determinants of active transportation from two ...


Public Transit Equity Analysis At Metropolitan And Local Scales: A Focus On Nine Large Cities In The Us, Greg P. Griffin, Ipek N. Sener 2016 Texas A&M Transportation Institute

Public Transit Equity Analysis At Metropolitan And Local Scales: A Focus On Nine Large Cities In The Us, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Recent studies on transit service through an equity lens have captured broad trends from the literature and national-level data or analyzed disaggregate data at the local level. This study integrates these methods by employing a geostatistical analysis of new transit access and income data compilations from the Environmental Protection Agency. By using a national data set, this study demonstrates a method for income-based transit equity analysis and provides results spanning nine large auto-oriented cities in the US. Results demonstrate variability among cities’ transit services to low-income populations, with differing results when viewed at the regional and local levels. Regional-level analysis ...
