Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman

Earth and Soil Sciences

Liquefaction of soils in response to earthquake shaking is a pressing issue in the state of California. Using Geographic Information Systems, Geological and lithology layers, along with criteria in order to separate out the data into four risk categories, a liquefaction risk assessment map was created for San Luis Obispo and Marin Counties. The accuracy of these maps was then assessed using liquefaction occurrences for San Luis Obispo County, and it was determined that while the map is somewhat accurate, in order to obtain a greater amount of accuracy and increase the usefulness of these maps, more data would need …

Lower Tropospheric Temperature Variability Over The Usa: A Gis Approach, Souleymane Fall, Dev Niyogi, Gilbert L. Rochon

GIS Day

We use the high resolution North American Regional Analysis (NARR) dataset to build for the United States a Temperature Change Index (TCI) based on four contributing variables derived from the layer-averaged temperature and lapse rate of the 1000mb - 700mb layer (near-surface to 3000 meters) for the 1979-2008 period. The analysis uses Geographic Information Systems (GIS) methods to identify distinct regional patterns based on aggregate temperature trends and variability scores. The resulting index allows us to identify and compare regions that experience high (low) temperature trends and variability that are referred to as hot spots (cold spots). The upper Midwest …

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, …

‘Buried Beneath The Waves’: Using Gis To Examine The Physical And Social Impact Of A Historical Flood, Mathew Novak, Jason Gilliland

Geography & Environment Publications

Natural disasters such as floods can periodically disturb and destroy the built and social fabric of communities. Despite their importance, specific ramifications of natural disasters can be overlooked in local histories due to a paucity of data. In this article we bring together several disparate sources of data within a historical geographic information system (HGIS) to study certain physical and social details of the flood which devastated the Town of London West, Canada on 11 July 1883. The integration of historical and contemporary data sources allow for the construction of a three-dimensional model of where the flood likely occurred. With …

An Analysis Of The Changing Land Use And Its Impact On The Environment Of Anyigba Town, Nigeria, Olarewaju Oluseyi Ifatimehin, Salihu Danlami Musa

Olarewaju Oluseyi Ifatimehin

Urbanization is a process that always initiates the continual transformation of land from one use to the other. Land transformation is presently being experienced in and around fast growing towns, like Anyigba in Kogi State. This study used Remote sensing and GIS techniques to identify, mark, and measure the extent of the various land uses from the Land use map of 1995 and Nigeriasat 1 imagery of 2006. The study revealed that there have been tremendous transformation in the various land uses, with the built-up area expanding more than other land uses with 398.4%. Gaining 167 ha, 613.45 ha, 159.62 …

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …

Gremo: A Gis-Based Generic Model For Estimating Relative Wave Exposure, Austen Pepper, Marjetta L. Puotinen

Faculty of Science - Papers (Archive)

Wave exposure plays a major role in shaping the ecological structure of nearshore communities, with different community types able to survive and/or thrive when typically exposed to different levels of wave energy. This can be quantified by taking direct field measurements with wave buoys over time and then manipulating the data to derive typical conditions. However, taking these measurements is only feasible for very limited areas due to logistical constraints, and generating them with numerical wave models can also be expensive to run and may require data inputs that are either lacking or are highly uncertain. Instead, the relative differences …

Geophysical Survey Of Greenwood Cemetery, Orlando, Florida, Dennis Wardlaw

Electronic Theses and Dissertations

Advances in geophysical and remote sensing technology, specifically with ground penetrating radar (GPR) and geographic information systems (GIS), have led to increased use for archaeological research within cemeteries. Because of its non-invasive manner and high resolution of subsurface anomalies, GPR is ideal for surveying areas with marked or unmarked graves within cemeteries. Using a GIS assists cemetery research by facilitating integration of datasets and projection of spatial data. What has not been attempted to this point is systematic attempting to correlate detection rates of marked graves using a GPR with the time frame of the grave while incorporating the data …

The Driving Force: A Comparative Analysis Of Gang-Motivated, Firearm-Related Homicides, Christa Polczynski

Electronic Theses and Dissertations

The knowledge of gang homicides is constantly increasing, but one aspect of gangs rarely studied is drive-by shootings (Dedel 2007; Hutson, Anglin, and Pratts 1994; Hutson, Anglin, and Eckstein 1996; Polczynski 2007; Sanders 1994; Sugarmann and Newth 2007). In this paper are comparative analyses of gang-motivated, firearm-related homicides perpetrated through a drive-by shooting to those which are not perpetrated through a drive-by shooting, by spatial and regression analyses. The data used for the analyses are a combination of incident variables, such as victim, offender, and incident characteristics, as well as social and economic characteristics of the communities in which the …

Reconstructing Landscape At Chavin De Huantar, Peru : A Gis-Based Approach, Daniel A. Contreras

Daniel A. Contreras

The landscape around the prehistoric Peruvian ceremonial center of Chavin de Huantar has undergone extensive geomorphic and anthropogenic change since the beginning of monumental construction at the site in approximately 1200 BCE. Archaeological and geomorphic stratigraphy from the site and its near periphery provide the data necessary to characterize these changes in detail. This paper reports on the use of GIS-based interpolation tools to approximate a complex prehistoric land surface using unevenly scattered point data. Such an interpolated surface serves as the basis for the reconstruction of the pre- Chavin landscape and assessment of landscape change contemporary with the site.
