Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou
International Journal of Geospatial and Environmental Research
This paper presents an exploratory spatial data analysis (ESDA) of road traffic crashes at different severity levels in West Virginia (WV). Although ESDA can support transportation safety decision-making by helping planners understand and summarize crash data, it is underutilized in practice. This paper describes the application of five representative easy-to-use method to identify crash patterns and high crash-risk counties in WV. Analysis of crash data from 2010 to 2015 indicated that traffic crashes in WV were not spatially correlated. However, crash severities were found to be positively correlated.

Predicting Northern Bobwhite Habitat In Semiarid Rangeland Using Landsat Imagery, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Multiple studies have attempted to model northern bobwhite (Colinus virginianus) distribution using classified remotely sensed imagery in combination with pattern recognition software. These models tend to be more accurate in humid subtropical regions. To identify bobwhite habitat in subhumid and semiarid rangeland, we performed our own classification on 4 LANDSAT scenes of Clay County, Texas, from July and December 2015. Stands of mature little bluestem (Schizachyrium scoparium) provide excellent bobwhite nesting cover and could be identified using LANDSAT imagery. Habitat was scored from 0 to 1.0 based on estimated range health, presence of little bluestem, and …

Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover
Journal of Geospatial Applications in Natural Resources
Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …

Using Gis And Remote Sensing To Analyze Lake Level Rise Of Étang Saumâtre, Haiti, Helenmary M. Hotz, Alan D. Christian
International Journal of Geospatial and Environmental Research
Haiti is the poorest country in the western hemisphere and is beset by catastrophic events of natural and anthropogenic origins. Therefore, Haiti is vulnerable to and ill-equipped to manage these events. Since 2004, the incidence and intensity of tropical storms over the island of Hispaniola has resulted in loss of life and been the catalyst for forced migration of the population, resulting in contamination of water and health issues, i.e. cholera. Our research uses GIS and Remote Sensing to address the potential flooding hazard to population and agriculture abutting the closed basin lake Étang Saumâtre. Our analysis of Landsat imagery …

Predicting Changes Of Rainfall Erosivity And Hillslope Erosion Risk Across Greater Sydney Region, Australia, Xihua Yang, Bofu Yu, Xiaojin Xie
International Journal of Geospatial and Environmental Research
Rainfall changes have significant effect on rainfall erosivity and hillslope erosion, but the magnitude of the impact is not well quantified because of the lack of high resolution rainfall data. Recently, the 2-km rainfall projections from regional climate models have become available for the Greater Sydney Region (GSR) at daily time step for the current (1990-2009) and future (2040-2059) periods. These climate projections allow predicting of rainfall erosivity changes and the associated hillslope erosion risk for climate change assessment and mitigation.
In this study, we developed a daily rainfall erosivity model for GSR to predict rainfall erosivity from the current …

The goal of this paper is to address the spatial disparity of health care access using a network-based health accessibility index method (NHAIM) in a Geographic Information System (GIS) environment. Ensuring a desired level of accessibility for patients is the …
Solar And Topographical Breeding Habitat Preferences Of Two Damselflies Calopteryx Aequabilis And Calopteryx Maculata, Christopher St. Andre
Solar And Topographical Breeding Habitat Preferences Of Two Damselflies Calopteryx Aequabilis And Calopteryx Maculata, Christopher St. Andre
Undergraduate Review
As the global climate changes many species are forced to adapt, but if the climate changes beyond their tolerance levels they can face extinction1. Scientists need to work fast in order to mitigate these extinctions. Using field observations of species’ habitats coupled with the use of geographic information systems (GIS), researchers can model the locations of ideal habitats. Using these models, scientists can work to improve conservation efforts by raising the populations of dwindling species or predicting locations to place new subpopulations. Data used in GIS are spatially explicit, so stored within individual data sets and information systems are locational …
