A Critical Spatial Econometric Counter Analysis of the Impact of New Toxic Facilities on Local Wages
Hegemonic assumptions and industry claims regarding the benefits of new toxic industrial facilities on local wages are tested and challenged. Analysis is performed by applying GIScience and Spatial Econometric methods within a critical framework. A call is made to develop more broadly the practice …

Geospatial Framework for the Use of Natural Resource Extraction in Public Private Partnerships
Resources for the maintenance and expansion of existing highway infrastructure are scarce. Public Private Partnerships (PPP) are feasible solutions to the concern of lagging investment. PPP are increasingly used for the procurement of services and goods, because of their flexibility and ability to …

Enhancing Coastal Community Resilience in North Carolina: Monitoring Erosion and Nature-based Solution Efficacy on a Fetch-limited Barrier Island
Fetch-limited barrier islands protect low-lying coastal communities like those in eastern North Carolina. They are natural barriers against powerful waves and storm impacts. However, coastal storms can subject barrier islands to elevated water levels and forceful waves, overwhelming their …

Extent of Alabama's terrestrial nature reserve system in representing ecosystem diversity: a coarse filter gap analysis
… do not effectively represent ecosystem diversity and biodiversity. In this study, Alabama's public and private reserve lands were analyzed to see how representative they were of biodiversity. The spatial distribution and characteristics of Alabama's nature reserves were examined using gap …

Assessing the relationship between high lightning events and storm mode in Northern and Central Alabama
Lightning is a dangerous and deadly hazard, yet it is often underestimated by the public and excluded from severe weather watches and warnings used by the National Weather Service. Previous studies have analyzed the relationship of lightning and storm intensity in relation to severe weather, but …

Characterizing Boreal Forest Fire Disturbance Boundaries Through Space And Time In Ontario
… resources but is increasingly threatened by wildland fires, which are becoming more frequent and affecting larger areas due to climate change. In response, this thesis compares wildland fire boundaries derived from vegetation index slopes with those provided by BorealDB a newly developed database …

Forest fragmentation mapping, change detection, and gas well site identification in remotely sensed imagery: the role of spatial resolution
This research focuses on identifying optimal data and methods for detecting and quantifying land cover/land use change associated with natural gas drilling in Appalachia. Airborne and satellite remote sensing provides a tool for examining land cover changes. Although change detection has been used …

Model Development and Incorporation of GIS Tools for Floodplain Management
… reduce flood damage to critical infrastructure and to protect the life and health of individuals from flooding. A major component of this effort is the monitoring of flood control structures such as dams because the potential failure of these structures may have catastrophic consequences. In …

Game day emergency: a flow and vector based GIS stadium evacuation model
The U.S. Department of Homeland Security has deemed anti-terrorism evacuation planning and simulation critically important for sport stadium security. In this study, a flow based geographic information system (GIS) vector evacuation model was built in ArcMap. The model was developed to compute a …

Exploring the utility of a GIScience approach to modeling invasive species: A case study of Ailanthus altissima
… the potential for integration of remotely sensed and GIS data into an agent-based modeling environment in order to model seed dispersal and subsequent establishment of windborne seeds. In order to explore the applicability of agent-based modeling to predicting seed dispersal, a case study was …

Scale and texture in digital image classification
This thesis is a theoretical and empirical study on textural properties of digital images. Spatial information exists at a hierarchy of scales and texture is a consequence of the objects in that hierarchy. Within-class texture results from the spatial arrangement of objects at the next finer level …

Assessing the cumulative impact of disturbance on canopy structure and chemistry in Appalachian forests
… a range of disturbance events over time, from stand-replacing disturbances, such as clear cuts, to ephemeral disturbances, such as insect outbreaks. By understanding the cumulative impact of disturbances on canopy structure and chemistry, we can gain insight into management strategies, assess a …

Interoperability between the StraboSpot graph database and GIS software– A Malpais Mesa Use Case
Geographic Information Systems (GIS) have been used by field geoscientists for decades to digitally collect data with several benefits: observations can be made in the field at a map independent scale while using multiple basemaps, the burdensome task of digitizing handwritten field notes and maps …
