Faculty of Informatics - Papers (Archive)
While geographic information systems (GIS) can provide information on the static locations of critical infrastructure and evacuation routes, they do not provide the dynamically changing locations of things and people on the move. In contrast, radio frequency identification (RFID) wireless network technology can automatically identify and track the movement of assets (i.e., fire engines, ambulances, and rescue workers) and vulnerable citizens on the move (i.e., the elderly and the disabled), and hence providing local governments and communities with real-time information and enhanced decision-making capabilities, during chaotic disaster response operations (i.e., evacuation). Although the potential high impact and strategic value of …

Reclaiming A Sense Of Place: Geospatial Technologies And The Flat Rock Cemetery Project, Jeffrey Glover, Kathryn Jackson, Johnny Waits
Geosciences Faculty Publications
The Flat Rock community in southern DeKalb County, Georgia (just outside Atlanta) is one of the oldest continually-occupied African-American communities in Georgia. Although history shows that many African-American communities in the South were broken apart as former slaves migrated north in search of jobs and a more equitable life, Flat Rock remained an intact community. This was largely due to the efforts of individuals who were able to purchase land and later sell it in small parcels to fellow community members. Proximity—both to ancestors and significant places—is a cross-culturally important component to the creation of a sense of community. Placed …

Streamflow Prediction Using Gis For The Kentucky River Basin, Bakkiyalakshmi Palanisamy
University of Kentucky Doctoral Dissertations
The study was aimed at developing a simple methodology for flow prediction in ungauged basins using existing data resources. For this purpose, the streamflow measurements across the Kentucky River Basin located in Kentucky, USA were obtained from United States Geological Survey (USGS) archive. The flow transferring characteristics of the subbasins of the Kentucky River Basin were obtained by combining downstream and upstream stream gauges. The flow transferring function thus derived were related to watershed, channel and flow characteristics of the subbasins by multiple regression analysis. The gauge pairs were divided into two classes of subbasins representing Upper and Lower Kentucky, …

Assessing The Vulnerability Of Asian Megadeltas To Climate Change Using Gis, Colin D. Woodroffe
Assessing The Vulnerability Of Asian Megadeltas To Climate Change Using Gis, Colin D. Woodroffe
Faculty of Science - Papers (Archive)
Susceptibility of Asian megadeltas to climate change, including sea-level rise, is investigated using GIS. The Indus, Ganges-Brahmaputra-Meghna, Irrawaddy, Chao Phraya, Mekong, Red, Pearl, Changjiang, and Huanghe deltas began to form around 6000 years ago and have prograded since. The surface topography of active and abandoned delta plains is examined using digital terrain models derived from Shuttle Radar Topography Mission data and channel morphology is investigated using radar imagery. After delta plains are abandoned they become increasingly dominated by tidal processes. Population density is estimated using gridded world population data but highly variable local microtopography and uncertainty regarding future climate changes …
Modeling Geographic Awareness Of Road Networks For Consistency Verification, Ari Kassin
Modeling Geographic Awareness Of Road Networks For Consistency Verification, Ari Kassin
Open Access Theses & Dissertations
Problems related to transportation and inspection of valuable or sensitive assets such as commercial products and materials, cultural items and works of art, and hazardous materials share similarities and can be modeled by a core set of abstract entities including a payload, a vehicle, a driver, and an inspector. To make the load handling capabilities of security monitoring and inspection systems more scalable, security can be increased by reducing the variability of transportation routes to a finite set of authorized routes between trip origin and destination locations. Then trip anomalies, which are unexpected trip variations, can be used in inspection …

Estimation Of The Area Of Sealed Soil Using Gis Technology And Remote Sensing, Stanisław Białousz, Przemysław Kupidura
Estimation Of The Area Of Sealed Soil Using Gis Technology And Remote Sensing, Stanisław Białousz, Przemysław Kupidura
Przemysław Kupidura
Soil sealing can be defined as the destruction or covering of soil by buildings, constructions and artificial layers completely or partly impermeable (asphalt, concrete, etc.) It is the most intense form of land consumption and is essentially an irreversible process. Soil is sealed when agricultural or other biologically land is taken into the built environment. It is also a continuing process within existing urban areas, especially where urban population and the density of built structures is increasing and residual inner-city green zones are reduced. The paper concerns the methodology for an estimation of the area of sealed soil using GIS …

Investigating Urban Sprawl Using Remote Sensing And Gis Technology, Przemysław Kupidura
Przemysław Kupidura
The paper concerns the analysis of urban sprawl. The presented example of Lomianki – the municipality situated in the neighbourhood of Warsaw – capital city of Poland, shows dynamic changes of rural-urban fringe, called sub-urbanization. This kind of process is characterized by incoherence of spatial structure, disproportions between development of built-up areas and transport network, underdevelopment of service built-up areas and public spaces and mixing of urban and rural structures. Such a dynamic development leads also to an increasing of area of sealed (impermeable) zones, what is very important due to water economics. The multi-temporal dataset of aerial and satellite …

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 …

Relationship Of Reef Fish Assemblages And Topographic Complexity On Southeastern Florida Coral Reef Habitats, Brian K. Walker, Lance K. B. Jordan, Richard E. Spieler
Marine & Environmental Sciences Faculty Articles
Reef fish assemblage relationships with in situ and lidar topographic measurements across the seascape were analyzed to evaluate the possibility of using lidar metrics as a proxy for prediction models. In situ topographic complexity (i.e., linear rugosity) was measured from 346 point-count fish surveys spanning the reef seascape. Lidar topographic measurements (i.e., surface rugosity, elevation, and volume) were obtained from a high-resolution lidar bathymetric dataset of each survey's footprint. The survey sites were characterized by an independently derived benthic habitat map. Reef fish abundance and species richness appeared to increase with increasing topographic complexity. Although significant, the relationship was weak. …

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, …

Shore Status, Evolution, And Storm Vulnerability Assessments For George Washington Birthplace National Monument, C. Scott Hardaway Jr., Donna A. Milligan, Kevin P. O'Brien, Christine A. Wilcox
Reports
The shoreline at the George Washington Birthplace National Monument (GEWA) is eroding and vulnerable to storms. Recent storms, such as Hurricane Isabel and Tropical Storm Ernesto impacted the region in 2003 and 2006, respectively. Large losses of the bank prompted the National Park Service to determine the vulnerability of the shore and its associated cultural, natural and archeological resources. This project maps the existing shoreline along the Potomac River and at the Memorial House on Popes Creek, provides an assessment of shore and bank dynamics, determines the rate of shoreline change between 1937 and 2007, and presents an analysis of …
Using Gis To Locate Areas For Growing Quality Coffee In Honduras, Ellen Mickle
Using Gis To Locate Areas For Growing Quality Coffee In Honduras, Ellen Mickle
Department of Environmental Studies: Undergraduate Student Theses
Abstract Small-scale coffee producers worldwide remain vulnerable to price fluctuations after the 1999-2003 coffee crisis. One way to increase small-scale farmer economic resilience is to produce a more expensive product, such as quality coffee. There is growing demand in coffee-producing and coffee-importing countries for user-friendly tools that facilitate the marketing of quality coffee. The purpose of this study is to develop a prototypical quality coffee marketing tool in the form of a GIS model that identifies regions for producing quality coffee in a country not usually associated with quality coffee, Honduras. Maps of areas for growing quality coffee were produced …

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr
Dr. Fanan Ujoh
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 …

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 …
Development Of A Gis Database For Water Resources Management In Ajman Emirate, Uae., Mohammad Rehan Yusuf
Development Of A Gis Database For Water Resources Management In Ajman Emirate, Uae., Mohammad Rehan Yusuf
Theses
The lack of freshwater resources represents a major constraint against the sustainable development in arid and semi-arid regions. Because of the scarcity and randomness nature of rainfall in arid regions, surface water resources are almost absent. Groundwater resources are always under stress and in many cases do not suffice the water demands for different sectors. Desalination plants are widely constructed to substitute for the water shortage. The UAE, including Ajman emirate, is witnessing a rapid development in the industrial, commercial, construction and agricultural fields which has led to a tremendous increase in water demands.
Proper management of the limited water …

Some humans spend a tremendous amount of effort to change landscapes from a “natural” state to a “developed” state for a variety of desirable economic uses, such as urban, agriculture, transportation, and mining. Others spend a tremendous amount of effort to prevent such development in order to conserve the landscapes for a variety of important environmental uses, such as biodiversity maintenance, carbon storage, water filtration, and landslide prevention. It would be efficient in theory if a society were to focus its development efforts at locations that give the largest economic utility per area developed, and to focus its conservation efforts …

A spatial information system (SIS) is critical to the hosting, querying, and analyzing of spatial data sets. The increasing availability of three-dimensional (3D) data (e.g. from aerial and terrestrial laser scanning) and the desire to use such data in large geo-spatial platforms have been dual drivers in the evolution of integrated SISs. Within this context, recent patents demonstrate efforts to handle large data sets, especially complex point clouds. While the development of feature-rich geo-systems has been well documented, the implementation of support for 3D capabilities is only now being addressed. This paper documents the underlying technologies implemented for the support …
