The Hyperwall: A Geospatial Education Exhibit For The Science Museum Of Virginia, Alexander Walton 2019 University of Redlands

The Hyperwall: A Geospatial Education Exhibit For The Science Museum Of Virginia, Alexander Walton

MS GIS Program Major Individual Projects

Modern museums rely on technologically advanced platforms to attract visitors and convey information. The Science Museum of Virginia (SMV) proposed a new interactive geospatial education exhibit called the EarthLab Data Hyperwall to support their mission statement of “inspiring Virginians to enhance their lives through science.” A hyperwall/video wall is a visualization tool composed of a large screen array used for education and collaborative work. The SMV’s Hyperwall Exhibit consists of a high resolution video wall controlled by a connected, visitor-accessible touchscreen. The exhibit educates visitors on several environmental and climatic topics using interactive maps to increase comprehension. This ...


A Hidden Markov Model For Matching Spatial Networks, Benoit Costes, Julien Perret 2019 The University of Maine

A Hidden Markov Model For Matching Spatial Networks, Benoit Costes, Julien Perret

Journal of Spatial Information Science

Datasets of the same geographic space at different scales and temporalities are increasingly abundant, paving the way for new scientific research. These datasets require data integration, which implies linking homologous entities in a process called data matching that remains a challenging task, despite a quite substantial literature, because of data imperfections and heterogeneities. In this paper, we present an approach for matching spatial networks based on a hidden Markov model (HMM) that takes full benefit of the underlying topology of networks. The approach is assessed using four heterogeneous datasets (streets, roads, railway, and hydrographic networks), showing that the HMM algorithm ...


Evaluating Existing Manually Constructed Natural Landscape Classification With A Machine Learning-Based Approach, Rok Ciglic, Erik Strumbelj, Rok Cesnovar, Mauro Hrvatin, Drago Perko 2019 University of Ljubljana

Evaluating Existing Manually Constructed Natural Landscape Classification With A Machine Learning-Based Approach, Rok Ciglic, Erik Strumbelj, Rok Cesnovar, Mauro Hrvatin, Drago Perko

Journal of Spatial Information Science

Some landscape classifications officially determine financial obligations; thus, they must be objective and precise. We presume it is possible to quantitatively evaluate existing manually constructed classifications and correct them if necessary. One option for achieving this goal is a machine learning method. With (re)modeling of the landscape classification and an explanation of its structure, we can add quantitative proof to its original (qualitative) description. The main objectives of the paper are to evaluate the consistency of the existing manually constructed natural landscape classification with a machine learning-based approach and to test the newly developed general black-box explanation method in ...


Discovery Of Topological Constraints On Spatial Object Classes Using A Refined Topological Model, Ivan Majic, Elham Naghizade, Stephan Winter, Martin Tomko 2019 The University of Melbourne

Discovery Of Topological Constraints On Spatial Object Classes Using A Refined Topological Model, Ivan Majic, Elham Naghizade, Stephan Winter, Martin Tomko

Journal of Spatial Information Science

In a typical data collection process, a surveyed spatial object is annotated upon creation, and is classified based on its attributes. This annotation can also be guided by textual definitions of objects. However, interpretations of such definitions may differ among people, and thus result in subjective and inconsistent classification of objects. This problem becomes even more pronounced if the cultural and linguistic differences are considered. As a solution, this paper investigates the role of topology as the defining characteristic of a class of spatial objects. We propose a data mining approach based on frequent itemset mining to learn patterns in ...


Public, Private And Tribal Lands In Humboldt And Trinity Counties, Nate A. Douglass 2019 Humboldt State University

Public, Private And Tribal Lands In Humboldt And Trinity Counties, Nate A. Douglass

Humboldt Journal of Social Relations

This map titled “Public, Private and Tribal Lands in Humboldt and Trinity Counties” was a commissioned project by Dr. Yvonne Everett in the Environmental Science and Management Department at Humboldt State University. The purpose of the map was to depict the overlap in land ownership and native, pre-European territories. The most challenging part of the project was finding a way to successfully represent multiple land ownership layers while also distinctly calling out former aboriginal territories, all in one map. For this, bold dotted lines with soft concentric halos seemed to do the trick. These aboriginal territories were manually digitized from ...

This map displays exciting color gradients representing the variation of the elevation in both Yosemite and Zion National Parks. It was created utilizing United States Geological Survey (USGS) National Map 3DEP 1/3rd arc-second Digital Elevation Models and Adobe Photoshop.


Hobet Mine Mountaintop Removal, Brian Murphy 2019 Humboldt State University

Hobet Mine Mountaintop Removal, Brian Murphy

Humboldt Journal of Social Relations

The Hobet Coal Mine is located in West Virginia, and was an active mining site for 41 years. At the time, it was one of the largest surface coal mines in the United States. The impacts of this particular mine are especially pronounced because of the sheer scale of alteration to the landscape caused by removing the peaks of mountains to retrieve the coal. The once verdant and biodiverse mountains have been obliterated, and when the coal is removed, the remaining earth is filled into nearby valleys, creating a flat plateau. This terrain has been destroyed, poisoned, and exploited by ...


Northern Appalachian Land Cover, Joshua Shindelbower 2019 Humboldt State University

Northern Appalachian Land Cover, Joshua Shindelbower

Humboldt Journal of Social Relations

This map was created using a combination of GIS, photo editing, and graphic design software after an inspiring road trip through the area. It shows the wide diversity of land cover across the region, and a key weak point in the Appalachian Mountains, known as “The Gaps of the Allegheny,” which allowed European immigrants to move toward fertile land deposited by millions of years of erosion. The reader can see that there is very little unused space in the region. Nearly every non-urban inch of land has been occupied for agricultural purposes, down to the thinnest sliver valleys. This map ...


Ball Court Map, Adam Wall 2019 Humboldt State University

Ball Court Map, Adam Wall

Humboldt Journal of Social Relations

This is a composite map of Structure 30 (STR 30), an ancient Mesoamerican ballcourt in Belize, excavated and documented as an archaeological site by Humboldt State University students and alumni. Each demarcated square or rectangle corresponds to a separate excavation map; field notes were consolidated and digitized individually, then pieced together based on alignment and overlaid atop an outline of the entire structure. Satellite imagery of the site was used as a reference to ensure accuracy. By this method, the previously isolated pockets of data, inherent to individual field notes, instead become parts of a greater whole, allowing a fuller ...


Dos Hambres To Gran Cacao Archaeological Mapping, Michael McDermott 2019 Humboldt State University

Dos Hambres To Gran Cacao Archaeological Mapping, Michael Mcdermott

Humboldt Journal of Social Relations

This map displays the spatial relationships and distribution of residential features throughout a portion of the Maya hinterlands near the site of Dos Hombres in Northwest Belize. Combining high resolution LiDAR data with detailed archaeology field data has allowed for accurate mapping of the features in this Mayan landscape. A unique aspect of this particular site is the presence of a causeway or “sacbe” which was used by the ancient Mayan people to distribute resources and move throughout their environment. The background terrain was created by manipulating the LiDAR data to generate a unique visualization that displays the human modified ...


The Southern California Coast, Gilbert Trejo 2019 Humboldt State University

The Southern California Coast, Gilbert Trejo

Humboldt Journal of Social Relations

The purpose of this map was to create a landscape view of my home region of Southern California that adequately displayed the complexity of it’s natural and man-made terrain. One of the challenges I faced was the amount of labeling in the greater Los Angeles (LA) area. I decided to not include any city borders because moving around LA feels more like moving across various neighborhoods and regions than crossing from one city to another. Slanting the text provided more space without making it too difficult to read. The orientation creates a more interesting layout than the usual north-up ...


Salmon Of The Klamath, Melissa Collin 2019 Humboldt State University

Salmon Of The Klamath, Melissa Collin

Humboldt Journal of Social Relations

The Klamath is a diverse bioregion widely known for its abundant population of salmon. It extends through the states of Oregon and California, and has a drainage basin of over 15,000 square miles that flows into the Klamath River. The three most prevalent species of salmon in the region (Coho, Steelhead, and Chinook) have all experienced sharp declines in populations since the mid-20th century. This is due to human activity such as commercial fishing, logging, dams, and urban development that has altered the salmon’s historic migration. This map aims to visualize the various waterways and water bodies that ...


Conflicts On The Klamath, Massimo Lambert-Mullen, Hop Norris 2019 Humboldt State University

Conflicts On The Klamath, Massimo Lambert-Mullen, Hop Norris

Humboldt Journal of Social Relations

Conflicts on the Klamath is a collaboration between Massimo Lambert-Mullen, a Humboldt State University Geography alumnus, and Hop Norris, a local artist, activist, and water protector based out of Crescent City, California. The inspiration behind this infographic is the complex and rich contemporary history of the Klamath river, including the establishment of reservations and the construction of dams, roads, and monuments that disrupt the flow of salmon and disrespect sacred sites. It is a politically motivated piece that means to convey the cultural and ecological importance of salmon and criticize government and settler actions to disenfranchise local Yurok, Hoopa, and ...


Historic Landmarks And Points Of Interest In Mendocino Ca, Jeremy McFarland 2019 Humboldt State University

Historic Landmarks And Points Of Interest In Mendocino Ca, Jeremy Mcfarland

Humboldt Journal of Social Relations

The Earth’s ocean ties all people together in more ways than one. For centuries, people have been drawn to the ocean for its vast openness and array of resources. Maritime heritage is the protection and preservation of humankind’s past and century old stories of cultures’ use of the ocean. By understanding individual connections to the ocean, more may be inspired to care for it. This map was developed to visualize the unique transition between land and sea, and capture the historic connection of this seascape town.


Book Review, Stanton Morse 2019 Texas State University

Book Review, Stanton Morse

Humboldt Journal of Social Relations

Overall, Making Spatial Decisions Using ArcGIS Pro: a Workbook is an excellent text for college-level students who have had a formalized introduction to ArcGIS Pro. The authors expertly provide an expansive list of methods and applicable knowledge yet to be had from previous versions. Surely, the text is not perfect, but what it lacks can be remedied by knowledgeable instruction. Kathryn Keranen and Robert Kolvoord succeed in offering a new lens to view the bright future of ArcGIS Pro to those of us still reluctant to entirely switch.


Cartographies Of Debt: Auto Title Loans And Spatial Inequality, Michihiro C. Sugata 2019 Humboldt State University

Cartographies Of Debt: Auto Title Loans And Spatial Inequality, Michihiro C. Sugata

Humboldt Journal of Social Relations

Despite being a decade removed from the 2008 Financial Crisis, an alarming number of Americans are turning to alternative finance service providers (AFSP) for “short term” loans. These loans typically carry triple digit interest rates and can contribute to exacerbating the financial precarity of the borrowers. This article investigates the relationship between the spatial distribution of the AFSP industry and considers the impacts of this saturated presence on the individuals who live in these neighborhoods. Using the Phoenix metropolitan area as a site of exploration, I examine where the industry has pooled and look at the descriptive characteristics of those ...


A Geographic Account Of Economic, Health, And Educational Disparities In Hartford’S Sheff Region, Casey D. Cobb 2019 University of Connecticut

A Geographic Account Of Economic, Health, And Educational Disparities In Hartford’S Sheff Region, Casey D. Cobb

Humboldt Journal of Social Relations

In the current study, I use geographic techniques to examine the distribution of key housing, economic, health, and educational indicators in metropolitan Hartford. I focus in particular on factors that bear upon the lives of children in this area, also known as the Sheff region—a reference to the long-standing Sheff v. O’Neill school desegregation lawsuit. The results reveal substantial disparities in the geographic distribution of important resources and outcomes across the racially and economically stratified region. Despite earnest school desegregation efforts, the opportunities, access, and resources available to children in municipalities across the metro Hartford region remain starkly ...

Mapping Maya Hinterlands: Lidar Derived Visualization To Identify Small Scale Features In Northwestern Belize, Jeremy Mcfarland, Marisol Cortes-Rincon Ph.D.

Humboldt Journal of Social Relations

This paper will discuss the processes and methods of relief visualization of LiDAR-derived digital elevation models (DEM’s) and classification of secondary data to identify archaeological remains on the ancient Maya landscape in northwestern Belize. The basis of the research explores various Geographic Information System (GIS) and cartographic techniques to visualize topographical relief. Graphic terrain maps assist archaeologists with predictive settlement patterns. The Relief Visualization Toolbox (RVT 1.3) aids to visualize raster DEM datasets in the predictive identification and interpretation of small-scale archaeological features. This dataset and methodology can be utilized to answer questions of population estimates, mobility costs ...


Agent-Based Models In Supporting Pedestrian Transportation Planning And Design, Nicholas A. Perdue 2019 Humboldt State University

Agent-Based Models In Supporting Pedestrian Transportation Planning And Design, Nicholas A. Perdue

Humboldt Journal of Social Relations

Agent-based models offer a new approach to understanding human-urban interactions in transportation systems, allowing individual entities within a system to be characterized with cognitive and behavioral properties. This paper discussed the role of agent-based representations of pedestrian transportation systems, detailing the underlying assumptions and techniques behind different types of pedestrian models and illustrating the differences between aggregate and individual agent representations. It then turns attention to the case study and the development of a cognitive pedestrian model as a way to illustrate the spectrum of potential spatial behaviors that are enabled by material changes to the transportation network. The paper ...
