Spatial Analysis Of A Bioterrorist Attack On Four Major United States Cities Using An Aerosolized Hemorrhagic Fever Virus, Kathryn Prinslow May 2011

Spatial Analysis Of A Bioterrorist Attack On Four Major United States Cities Using An Aerosolized Hemorrhagic Fever Virus, Kathryn Prinslow

Master's Theses

Before the attack on September 11,2001, the United States was very vulnerable to a biological attack. Since then, those responsible for the security of the United States Homeland Security have become more aware of the country's vulnerability. Biological agents have the potential to give small groups of people unprecedented power to terrorize, as indicate by the "Amerithrax" attack in 2001, and of all of these agents, none have more potential for destruction than Ebola Hemorrhagic Fever (EHF). This research uses one of the deadliest viruses that have not been eradicated to identify the number of fatalities in an outbreak affecting …


Utilization Of Geographic Information System For Research, Management, And Education In The Natural Resources Management Department At California Polytechnic State University, San Luis Obispo, David In Yun Feb 2011

Utilization Of Geographic Information System For Research, Management, And Education In The Natural Resources Management Department At California Polytechnic State University, San Luis Obispo, David In Yun

Master's Theses

Geographic Information System (GIS) is “an organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information” (ESRI, 1997a). The Natural Resources Management Department at California Polytechnic State University, San Luis Obispo, California, hereafter NRM, was one of the early users of GIS technology. Although GIS was primarily used as an educational tool, it was also used for cataloging and displaying resource information for management planning and research projects. As the computing technology advanced, GIS became more powerful and easier to use. NRM faculty and …


Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White Mar 2010

Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White

Master's Theses

Forest roads and stream channels are mapped using a variety of remote sensing and ground-based techniques. In densely forested areas, conventional remote sensing methods provide limited terrain information, while ground-based surveys can be time-consuming, difficult, and expensive. Light Detection and Ranging (LiDAR) is an airborne remote sensing technology used to create high-resolution digital elevation models (DEMs) of the earth’s surface. This study tests the accuracy of forest road and stream channel features mapped using LiDAR in the steep, forested terrain of California’s Santa Cruz Mountains. A conventional total station survey was used to determine centerline position and elevations along a …


Energetic Path Finding Across Massive Terrain Data, Andrew N. Tsui Jun 2009

Energetic Path Finding Across Massive Terrain Data, Andrew N. Tsui

Master's Theses

Before there were airplanes, cars, trains, boats, or bicycles, the primary means of transportation was on foot. Unfortunately, many of the trails used by ancient travelers have long since been abandoned. We present a software tool which can help visualize and predict where these forgotten trails might lie through the use of a human-centered cost metric. By comparing the paths generated by our software with known historical trails, we demonstrate how the tool can indicate likely trails used by ancient travelers. In addition, this new tool provides novel visualizations to better help the user understand alternate paths, effect of terrain, …
