Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari 2019 Selected Works

Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari

Alice Fornari

Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as ...

Wildfire Activity And Land Use Drove 20th‐Century Changes In Forest Cover In The Colorado Front Range, Kyle Rodman, Thomas T. Veblen, Sara Saraceni, Teresa B. Chapman

Geography Graduate Contributions

Recent shifts in global forest area highlight the importance of understanding the causes and consequences of forest change. To examine the influence of several potential drivers of forest cover change, we used supervised classifications of historical (1938–1940) and contemporary (2015) aerial imagery covering a 2932‐km2study area in the northern Front Range (NFR) of Colorado and we linked observed changes in forest cover with abiotic factors, land use, and fire history. Forest cover in the NFR demonstrated broad‐scale changes 1938–2015 and overall cover increased 7.8%, but there was notable spatial variability and many sites also experienced ...


Using Gis And Remote Sensing To Map Grassroots Sustainable Development For A Small Ngo In Nepal, Suzanne C. Walther, Elizabeth M. Dengenis, Krishna Gurung 2019 University of San Diego

Using Gis And Remote Sensing To Map Grassroots Sustainable Development For A Small Ngo In Nepal, Suzanne C. Walther, Elizabeth M. Dengenis, Krishna Gurung

International Journal of Geospatial and Environmental Research

Geographic information systems, through analysis and visualizations, can aid in pursuing and improving sustainable development. Thousands of Non-Governmental Organizations (NGOs) in developing countries provide a wide range of services and local organizations with fewer resources must often be more efficient to offer their services effectively. The accessibility of spatial data for assessment and, in turn, improved planning could enable these organizations to increase efficiency, thereby maximizing aid and sustainable development, as well as the number of people helped in a variety of ways. Focusing on mapping outreach and quantifying land use for a locally run NGO in Nepal, this study ...

Implications Of Dam Removal: Modeling Streamflow In Lansing, Michigan Using The Soil And Water Assessment Tool, Ryan J. Filbin, Laiyin Zhu, Lisa Dechano-Cook, Lei Meng

International Journal of Geospatial and Environmental Research

This paper uses hydrologic modeling methods to determine the effects of dam removal in Lansing, Michigan, on the streamflow of the Grand River, flooding risks, and flood mitigation strategies. In Michigan, more than one-half of the state’s dam infrastructure is more than 50 years old, and more than one-third are classified as having a moderate-to high-risk potential. Lansing, Michigan, contains two moderate-to high-risk dams along the Grand River that are a significant hazard to the surrounding community in the event of structural failure. This research utilizes the Soil and Water Assessment Tool (SWAT) to model the impacts of the ...


Geospatial Analysis Of Care And Mortality In The 2014 Liberia Ebola Outbreak, Marion Carlton Kinkade 2019 Walden University

Geospatial Analysis Of Care And Mortality In The 2014 Liberia Ebola Outbreak, Marion Carlton Kinkade

Walden Dissertations and Doctoral Studies

The Ebola outbreak in West Africa in 2014 to 2016 had more than 28,000 suspected, probable, and confirmed cases. It was the largest Ebola outbreak in history. Of the 28,000 cases in the three Ebola-affected countries, Liberia had 10,000 cases with almost 5,000 deaths. The Ebola Virus Disease (EVD) entered Liberia along the border of Guinea and moved to the capital city of Monrovia where the virus spread. Ebola Treatment Units (ETUs) were constructed throughout the response in locations where there were available facilities versus distance to care challenges. This study examined the association of distance ...

Assessing The Causal Impact Of Chinese Aid On Vegetative Land Cover In Burundi And Rwanda Under Conditions Of Spatial Imprecision, Robert Marty, Seth Goodman, Michael Lefew, Carrie B. Dolan, Ariel Benyishay, Daniel Runfola

Arts & Sciences Articles

There has been considerable debate regarding the efficacy of international aid in meeting the dual goals of human development and environmental sustainability. Many donors have sought to engage with this challenge by introducing environmental safeguard and monitoring initiatives; however, evidence on the success of these interventions is limited. Evaluating aid is a particular challenge in the case of donors that do not disclose information on the nature, geographic location, or extents of their interventions. In such cases, new methods that extract and geoparse data on the activities of opaque donors through the manual interpretation of thousands of news and other ...


The Role Of Mining Ponds In The Hungarian Greenway Network, Ildikó M. Bugyi, Nóra H. Horváth, Dalma Varga 2019 Szent István University, Department of Landscape Protection and Reclamation

The Role Of Mining Ponds In The Hungarian Greenway Network, Ildikó M. Bugyi, Nóra H. Horváth, Dalma Varga

Proceedings of the Fábos Conference on Landscape and Greenway Planning

The aim of our research is to present the current state of mining ponds, wetlands (created by mining activity in Hungary) and to give support to the mining ponds’ nature protection importance and their role in green infrastructure.

This research topic is very important, partly because of the lack of data related to mining ponds, but also because wetlands and their connecting blue and green infrastructure are playing a more important role today in reducing the effects of climate change.

A GIS analysis was made using data from the national mining register, the CORINE Land Cover and Agricultural Parcel Identification ...


Boom And Decline: When Greenways Link Low And High Ses Neighborhoods, Margaret Bryant 2019 Center for the Urban Environment, Department of Landscape Architecture, State University of New York College of Environmental Science and Forestry

Boom And Decline: When Greenways Link Low And High Ses Neighborhoods, Margaret Bryant

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Social and economic inequalities in American cities mean that “booming cities” all have neighborhoods that are not thriving, and “declining cities” are likely to have some areas that are booming. Disadvantaged urban neighborhoods with high numbers of people living in poverty exist in all cities, but they are more pervasive in declining cities. Greenways, linear features in the urban landscape, cut across neighborhoods with varying levels of socioeconomic status (SES), depending on their design and place-specific characteristics. Where greenways link wealth to poverty, interesting concerns, issues, and opportunities arise. This paper reviews existing research on phenomena associated with this particular ...

Landscape, Ecological And Visual Impacts Of A Stream Restoration In Hungary, Zsombor Boromisza, Attila Gergely, Eszter Jákli, Cai Xuecheng

Proceedings of the Fábos Conference on Landscape and Greenway Planning

In the course of the preparation for the restoration of the Váli-stream, an environmental impact assessment (EIA) and, as a part of it, foundational wildlife and landscape protection studies were carried out. The goal of the study is to reveal the significant impacts of a planned stream restoration on wildlife protection, and later on, to propose mitigation measures on the adverse effects. The other main goal of the study is to evaluate the intervention’s effects on the landscape, regarding the landscape character, land use, landscape structure and scenery as well.

Interlinking People And Nature Through The Technologized Urban Greenway, Dorottya Bekesi

Proceedings of the Fábos Conference on Landscape and Greenway Planning

The project area is located along the Danube River in Budapest, and as a peninsula, has a significant role in the city on an ecological level. In my research, I present the project from the industrial revolution up to the present day. In my concluding remarks, various design ideas for implementation on the peninsula and in its neighborhood were demonstrated.

The abandoned Népsziget with its industrial site holds a lot of potential for cultural and environmental development. When it comes to city planning in Budapest the main issue is the decrease of greenfield territories in the suburban areas while the ...


On The Coastline: The Genesis Of Green Infrastructure Towards A Future Sustainable Landscape For The City Of Maputo, Mozambique, Ana Beja da Costa, Luis Ribeiro 2019 LEAF, Instituto Superior de Agronomia, Universidade de Lisboa

On The Coastline: The Genesis Of Green Infrastructure Towards A Future Sustainable Landscape For The City Of Maputo, Mozambique, Ana Beja Da Costa, Luis Ribeiro

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Cities in Africa, where the most remarkable forthcoming developments in the overall pattern of urbanization are expected, and quite notably in Sub-Saharan cities such as Maputo, experience accelerating population increases that stress urban infrastructures beyond capacity, and increase pressure on existent valuable ecosystems. In the city’s coastal plains, the recently constructed Maputo ring road and Katembe bridge are drawing urban development towards the last stretch of vacant land of the Municipality, compromising the flood plains and mangrove ecosystems.

This paper aims to refine the planning discourse by systematizing urban strategies associated to green infrastructure functions, having mangrove wetlands as ...


Considering The Non-Programming Geographer's Perspective When Designing Extracurricular Introductory Computer Programming Workshops, Thomas R Etherington 2018 The University of Maine

Considering The Non-Programming Geographer's Perspective When Designing Extracurricular Introductory Computer Programming Workshops, Thomas R Etherington

Journal of Spatial Information Science

Computer programming is becoming an increasingly important scientific skill, but geographers are not necessarily receiving this training as part of their formal education. While there are efforts to promote and support extracurricular introductory computer programming workshops, there remain questions about how best to deliver these workshops. Therefore, as part of a recent introductory programming extracurricular workshop I organized for non-programing geographers, I tried to understand more about their perceptions of computer programming. I identify that one of the most important aspects for geographers to learn to computer program is to have training that is domain specific to ensure that the ...


Towards Harmonizing Property Measurement Standards, Abdullah Kara, Volkan Çağdaş, Ümit Işıkdağ, Bülent Onur Turan 2018 The University of Maine

Towards Harmonizing Property Measurement Standards, Abdullah Kara, Volkan Çağdaş, Ümit Işıkdağ, Bülent Onur Turan

Journal of Spatial Information Science

Area and volume values of buildings and building parts have been used in many applications including taxation, valuation and land use planning. Many countries maintain a national standard for representing the measurements of floor areas in buildings. The national standards generally use similar basis for measuring building floor areas, in fact, areas specified in national standards often have semantic differences. Therefore, a number of international standards have been developed for harmonizing floor area measurements; however, they also have differences. This study aims at harmonizing the floor areas defined in the international property measurement standards by revealing the semantic relations between ...

Hyper-Local Geographically Weighted Regression: Extending Gwr Through Local Model Selection And Local Bandwidth Optimization, Alexis Comber, Yunqiang Wang, Yihe Lü, Xingchang Zhang, Paul Harris 2018 The University of Maine

Hyper-Local Geographically Weighted Regression: Extending Gwr Through Local Model Selection And Local Bandwidth Optimization, Alexis Comber, Yunqiang Wang, Yihe Lü, Xingchang Zhang, Paul Harris

Journal of Spatial Information Science

Geographically weighted regression (GWR) is an inherently exploratory technique for examining process non-stationarity in data relationships. This paper develops and applies a hyper-local GWR which extends such investigations further. The hyper-local GWR simultaneously optimizes both local model selection (which covariates to include in each local regression) and local kernel bandwidth specification (how much data should be included locally). These are evaluated using a measure of model fit. The hyper-local GWR approach evaluates different kernel bandwidths at each location and selects the most parsimonious local regression model. By allowing models and bandwidths to vary locally, this approach extends and refines the ...


Georeferencing Places From Collective Human Descriptions Using Place Graphs, Hao Chen, Stephan Winter, Maria Vasardani 2018 The University of Melbourne

Georeferencing Places From Collective Human Descriptions Using Place Graphs, Hao Chen, Stephan Winter, Maria Vasardani

Journal of Spatial Information Science

Place descriptions in everyday communication or in online text provide a rich source of spatial knowledge about places. Such descriptions typically consist of references to places and spatial relationships between them. An important step to utilize such knowledge in information systems is georeferencing the referred places. Beside place name disambiguation, another challenge is that a significant proportion of place references in such descriptions are not official place names indexed by gazetteers, thus cannot be resolved easily. This paper presents a novel approach for georeferencing places from collective descriptions using place graphs, regardless of whether they are referred to by gazetteered ...

Towards Place-Based Exploration Of Instagram: Using Co-Design To Develop An Interdisciplinary Geovisualization Prototype, Catherine Emma Jones, Daniele Guido, Marta Severo

Journal of Spatial Information Science

An abundance of geographic information is hidden within texts and multimedia objects that has the potential to enrich our knowledge about the relationship between people and places. One such example is the geographic information embedded within user-generated content collected and curated by the social media giants. Such geographic data can be encoded either explicitly as geotags or implicitly as geographical references expressed as texts that comprise part of a title or image caption. To use such data for knowledge building there is a need for new mapping interfaces. These interfaces should support both data integration and visualization, and geographical exploration ...

The Evacuation Of Phnom Penh During The Cambodian Genocide: Applying Spatial Video Geonarratives To The Study Of Genocide, James A. Tyner, Andrew Curtis, Sokvisal Kimsroy, Chhunly Chhay 2018 Kent State University

The Evacuation Of Phnom Penh During The Cambodian Genocide: Applying Spatial Video Geonarratives To The Study Of Genocide, James A. Tyner, Andrew Curtis, Sokvisal Kimsroy, Chhunly Chhay

Genocide Studies and Prevention: An International Journal

On April 17, 1975 Khmer Rouge soldiers began the forcible evacuation of Phnom Penh, Cambodia’s capital city. The evacuation has been the subject of considerable debate surrounding the Cambodian genocide and remains a topic of prime importance toward the understanding of Khmer Rouge policy and practice. In this field note, we present a geographically-informed account of the evacuation in order to provide a more fine-grained analysis of Khmer Rouge practice. More specifically, employing spatial video geonarratives, we provide a systematic investigation of the evacuation, as retraced by six evacuees. In so doing we contribute also to the emergent use ...


Managing Electric Utility Assets For The City Of Aspen, Colorado, Hamish Henderson 2018 University of Redlands

Managing Electric Utility Assets For The City Of Aspen, Colorado, Hamish Henderson

MS GIS Program Major Individual Projects

This project describes how an electric network can be modeled in GIS. In particular it will look at the City of Aspen’s electric distribution network. The City of Aspen, Colorado has a small underground electric network that has historically only been understood by a few individuals. These individuals are nearing retirement which has sparked a need for a transfer of knowledge. Over the last few years, the electric network has been slowly moved into a GIS database with a built in Geometric Network. The City of Aspen wants to move all of its utility assets, water, storm water and ...
