Displaced Spaniards Data Tables, Karl D. Qualls

Stalins Niños - GIS Maps

We have created a series of maps using Geographic Information System (GIS) in order to analyze and visualize the data from Memoria: en memoria de los combatientes españoles que cayeron luchando contra el fascismo y por la libertad junto al pueblo ruso en la Segunda Guerra Mundial, 1941-1945 (Madrid: Fundación Nostalgia, 2000), which is a record Spaniards displaced during the Spanish Civil War who then died in the USSR during the Second World War.

The process began with the creation of a master spreadsheet using Excel that was divided into two sheets--combat deaths and non-combat deaths—to mirror the structure ...


Deciphering Public Transit Ridership In Baton Rouge: Spatial Disaggregation Approaches, Xuan Kuai 2019 Louisiana State University

Deciphering Public Transit Ridership In Baton Rouge: Spatial Disaggregation Approaches, Xuan Kuai

LSU Doctoral Dissertations

Background: Surveys across the U.S. reveal that commuters driving personal vehicles spend a significant amount of time in traffic, while public transit, as an efficient commuting mode, has been largely underutilized.

Purpose: What causes a low public transit ridership? How could public transit ridership be explained by demographic, socio-economic and spatial characteristics of neighborhood? This study answers these questions by deciphering the relationships between public transit ridership and various factors in a medium-size city in southern U.S. – Baton Rouge, Louisiana.

Methods: Non-spatial and spatial data in a larger areal unit (e.g., block group) are used to infer ...


Impacts Of Spatial Patterns Of Rural And Exurban Residential Development On Agricultural Trends In The Intermountain West, Saleh Ahmed, Douglas Jackson-Smith 2019 Boise State University

Impacts Of Spatial Patterns Of Rural And Exurban Residential Development On Agricultural Trends In The Intermountain West, Saleh Ahmed, Douglas Jackson-Smith

Saleh Ahmed

In recent years, counties in the Intermountain West (Colorado, Idaho, Montana, Wyoming, and Utah) have experienced rapid population growth and housing development, and much of this growth is occurring outside of urban areas. Residential development often has negative impacts on farmlands, farm viability, and environmental services provided by working landscapes. We used county-level data to identify the association between the intensity and spatial patterns of residential settlement and trends in selected farm outcomes between 1997 and 2012 in the region. Results demonstrate that accounting for the spatial pattern or degree of fragmentation and clustering of rural and exurban residential development ...


The Importance Of Landscape Position Information And Elevation Uncertainty For Barrier Island Habitat Mapping And Modeling, Nicholas Matthew Enwright 2019 Louisiana State University and Agricultural and Mechanical College

The Importance Of Landscape Position Information And Elevation Uncertainty For Barrier Island Habitat Mapping And Modeling, Nicholas Matthew Enwright

LSU Doctoral Dissertations

Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism. As a result, natural resource managers are concerned with monitoring changes to these islands and modeling future states of these environments. Landscape position, such as elevation and distance from shore, influences habitat coverage on barrier islands by regulating exposure to abiotic factors, including waves, tides, and salt spray. Geographers commonly use aerial topographic lidar data for extracting landscape position information. However, researchers rarely consider lidar elevation uncertainty when using automated processes for extracting elevation-dependent habitats from lidar data ...


Open Source Mapping In Latin America: Collaborative Approaches In The Classroom And Field, Marie Price, Andrii Berdnyk, Sudie Brown 2019 George Washington University

Open Source Mapping In Latin America: Collaborative Approaches In The Classroom And Field, Marie Price, Andrii Berdnyk, Sudie Brown

Journal of Latin American Geography

Open source mapping platforms (such as OSM) are innovative tools that can enhance student learning and engagement in Latin American geography courses. Use of these tools can also facilitate new collaborations between students/scholars and communities responding to social and economic challenges in Latin America. In this paper we discuss use of these tools in three different educational settings. We begin by describing the work of YouthMappers, a new international network of open source mappers that formed in 2015 with chapters in Latin America. YouthMappers can be a resource for geography departments anywhere in the world interested in developing open ...


Lidar-Based Sinkhole Detection And Mapping In Knox County, Tennessee, J Clint Shannon, David Moore, Yingkui Li, Cathy Olsen 2019 University of Tennessee, Knoxville

Lidar-Based Sinkhole Detection And Mapping In Knox County, Tennessee, J Clint Shannon, David Moore, Yingkui Li, Cathy Olsen

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Sinkholes are one of the major causes of damage to roads, buildings, and other infrastructure throughout the US. Sinkholes near or on roads are especially costly and occasionally deadly. Knox County and much of East Tennessee are located within karst areas (comprised of porous and soluble limestone and dolomite), deeming it at risk for sinkholes. Currently, Knox County uses contour maps to manually identify sinkholes. Supported by a geographic information system (GIS), we developed a streamlined model to identify the locations and extents of potential sinkholes using 1.3-ft resolution LiDAR (Light Detection and Ranging) data and applied it to ...


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 ...
