Characterizing Clustering Models Of High-Dimensional Remotely Sensed Data Using Subsampled Field-Subfield Spatial Cross-Validated Random Forests, Andrew B. Whetten
Characterizing Clustering Models Of High-Dimensional Remotely Sensed Data Using Subsampled Field-Subfield Spatial Cross-Validated Random Forests, Andrew B. Whetten
International Journal of Geospatial and Environmental Research
Clustering models are regularly used to construct meaningful groups of observations within complex datasets, and they are an exceptional tool for spatial exploratory analysis. The clusters detected in a recent spatio-temporal cluster analysis of leaf area index (LAI) in the Columbia River Basin (CRB) require further investigation since they are only derived using a single greenness metric. It is of great interest to further understand how greening indices can be used to determine separation of sites across an array of remotely sensed environmental attributes. In this prior work, there are highly localized minority clusters that were detected to be most …

The Spatial Patterns Of Pluvial Flood Risk, Blue-Green Infrastructure, And Social Vulnerability: A Case Study From Two Alaskan Cities, Arun K. Pallathadka, Heejun Chang, Idowu Ajibade
International Journal of Geospatial and Environmental Research
Flooding is a serious form of natural hazard in Alaska, USA. Two of Alaska’s biggest cities, Anchorage and Fairbanks, have experienced flooding of varying magnitude since the cities were first settled in the early 20th century. Although flood mitigation measures such as blue-green infrastructure (BGI) are rising in prominence, the spatial relationship of BGI, urban pluvial flood (UPF) zone, and social vulnerability remains understudied. This study delineates the UPF zone of Anchorage and Fairbanks using the Blue Spot modeling and correlates it with the distribution of BGI at Census Block Group (CBG) scale, focusing on underlying social vulnerability using a …
Measuring Spatio-Temporal Responses To Hurricane Matthew Employing Twitgis, Seungil Yum
Measuring Spatio-Temporal Responses To Hurricane Matthew Employing Twitgis, Seungil Yum
International Journal of Geospatial and Environmental Research
This study explores spatio-temporal responses to Hurricane Matthew across the US states by analyzing Twitter data. This study finds that people in different states and periods respond differently to Hurricane Matthew. For instance, people in the Midwest and Northeast regions show a high proportion of tweets in the pre-hurricane period. Those in the Southeast region demonstrate a high proportion of those in the hurricane period, and those in the West region show a high proportion of those in the post-hurricane period. This study also finds that people increase long distance trips (over 100 km) and decrease short distance trips (within …

Geological Lineament Assessment From Passive And Active Remote Sensing Imageries, Ainyyafiatty Arifin, Nor A. Adnan
Geological Lineament Assessment From Passive And Active Remote Sensing Imageries, Ainyyafiatty Arifin, Nor A. Adnan
International Journal of Geospatial and Environmental Research
Lineament is any extensive linear feature on the Earth’s surface that can be identified when there is a change in the topographical data. The advancement of technologies in remote sensing and Geographical Information Sciences (GIS) lead to the various studies and methods in mapping lineaments due to the availability of data from small to large scale areas. Lineament can be extracted from remote sensing data either with manual, semi-automatic or automatic image processing techniques that incorporate in numerous remote sensing and GIS software. Manually digitizing or tracing the aerial photograph is a subjective method as the lineament will be interpreted …

International Journal of Geospatial and Environmental Research
The availability of watershed delineation that has been generated from DEM data is difficult to obtain and the accessibility of DEM data which are unrestricted and precise are hard to obtain in Malaysia. The aim of this study is to examine the accuracy of watershed delineation between Digital Elevation Model (DEM) from ASTER and SRTM in Johor State Malaysia. In this study, free online data sources from USGS website are used to delineate watershed from ASTER and SRTM satellite imageries. The hydrological modelling tool namely ArcSWAT is utilized to delineate watersheds for both DEM datasets. Both DEM data that had …
Travel Time Patterns Of Students With Special Needs To Special Education Integrated Program-Based Schools In Johor Bahru, Malaysia: An Initial Finding, Nurul Hawani Idris, Nur Afiqah Ahmad Bakhtiar, Mohamad Hafis Izran Ishak
Travel Time Patterns Of Students With Special Needs To Special Education Integrated Program-Based Schools In Johor Bahru, Malaysia: An Initial Finding, Nurul Hawani Idris, Nur Afiqah Ahmad Bakhtiar, Mohamad Hafis Izran Ishak
International Journal of Geospatial and Environmental Research
Education for all has been a global priority to ensure that all students have equal access to high-quality education regardless of disability or minority status. In Malaysia, the special education integrated programme (SEIP) is designed to close the inequality gap by integrating special education into existing government and vernacular schools. Numerous studies examine the travel patterns of regular students to school, resulting in a dearth of research on the travel patterns of special needs students to formal school. Thus, this paper uses spatial analysis to demonstrate the travel patterns of students with special needs to SEIP schools. This paper demonstrated …

This work is a compilation of several research projects undertaken by the author. Each research effort identifies a problem that has been addressed traditionally using methods that are significantly costly, to such an extent that, in general, funding, convenience, and practicality are primary limiting factors to their effective implementation. In each case, the author has been able to either build upon existing, less expensive alternatives, or even invent novel approaches. The fundamental recurring research question is, can creative, even novel, computational approaches make more efficient use of resources to interpret or present data in such a way as to make …
An Internatural Communication Study Of Identity Within Nonprofit Animal Shelters, Samentha Emily Sepúlveda
An Internatural Communication Study Of Identity Within Nonprofit Animal Shelters, Samentha Emily Sepúlveda
Theses and Dissertations
In a two-part study of this dissertation project, I relied on qualitative research methods to examine the stories of animal shelter employees and volunteers—stories about animal shelters, animal sheltering, and shelter animals—to analyze communication processes that shape staff-identity, organizational-identity, and organizational identification. This project was guided by the communicative constitution of organizations (CCO) approach, which frames communication as not simply something that happens within an organization, but rather argues organization happens in communication. Furthermore, contributing to internatural communication research, this project explored identity and identification from a “more-than human” perspective. Relating CCO and internatural communication to research in this dissertation …
Bottom-Up Understanding Of Informal Settlements: Perspectives Of Urban Slum Dwellers In Nima, Ghana., Bernard Apeku
Bottom-Up Understanding Of Informal Settlements: Perspectives Of Urban Slum Dwellers In Nima, Ghana., Bernard Apeku
Theses and Dissertations
More than a quarter of the world’s population lives in informal settlements which house a rapidly growing proportion of the inhabitants of cities in sub-Saharan Africa, such as Accra, Ghana, and in the Global South more generally. However, scholars have shown that the urban planning and urban redevelopment strategies that affect these settlements are top-down in character with minimal resident participation. These prevailing planning and redevelopment strategies are based on the outsiders’ perceptions of informal neighborhoods, rendering them quite inefficient. Therefore, to develop workable policies and strategies that will improve the living condition of informal urban settlers, it is important …
