A Pragmatic Gis-Oriented Ontology For Location Based Services, Jun Shen, Aneesh Krishna, Shuai Yuan, Ke Cai, Yuemin Qin

Faculty of Informatics - Papers (Archive)

With advances in automatic position sensing and wireless connectivity, location-based services (LBS) are rapidly developing, particularly in fields of geographic, tourism and logistic information systems. Currently, Web service has been viewed as one of most significant innovations in business industry, and designed on demand to provide spatial related information for LBS consumption. However, the traditional Web Service Description Language (WSDL) cannot meet those requirements, as WSDL is not able to support semantic content and information. In recent years, Ontology came up with an effective approach to enhance service description, automated discovery, dynamic composition, enactment, and other tasks such as managing …

Watershed land and hydrology are resources that are very important in agricultural development. Adequate and proper land use planning and management of these resources is of ultimate importance in sustainable development. In this study remote sensing and Geographic Information System (GIS) techniques were used to generate information on the current status and utilization potentials of the Kubili watershed and generate local specific micro watershed development plans for the area. The study revealed that about 33.25 per cent of the land cover is used for rain fed agriculture that lacks sufficient soil and moisture to support good yield. The drainage density …

Gis Aided Archaeological Research Of El Camino Real De Los Tejas With Focus On The Landscape And River Crossings Along El Camino Carretera., Jeffrey M. Williams

Faculty Publications

Many generations of indigenous pathways through the forests of eastern Texas have their origins obscured in antiquity. Utilized by early European explorers, these pathways became modified through heavy use and the expansions and improvements needed to accommodate easy passage of European horses and carts and finally the heavy wagons of Anglo-American settlers. The first road through Texas, El Camino Real de Los Tejas, utilized portions of these early trails.

El Camino Carretera (known as the cart road) is an early segment of El Camino Real de los Tejas that crossed the Sabine River at the boundary between Texas and Louisiana. …

The Decline Of Fowler's Toad (Bufo Fowleri) In Southern Louisiana: Molecular Genetics, Field Experiments And Landscape Studies, Laura Sanders Vogel

University of New Orleans Theses and Dissertations

Two of the most pervasive threats to species biodiversity are invasive species and habitat loss and degradation. Invasive species are often relatively insensitive to disturbance and many expand their range into disturbed and fragmented habitats. This dissertation uses an interdisciplinary approach to investigate how anthropogenic habitat disturbance is precipitating a range expansion in an invasive toad species, Bufo nebulifer, which is driving a decline in its native congener, B. fowleri. I employed a remote sensing and GIS study using historical data to compare changes in the two species distributions and habitat changes, a molecular genetic study to identify interspecific hybrids …

Mapping Better Business Strategies With Gis, Tin Seong Kam

Research Collection School Of Computing and Information Systems

The value of location as a business measure is fast becoming an important consideration for organisations. GIS (Geographical Information Systems), with its capability to manage, display, analyse business information spatially, is emerging as a powerful location intelligence tool. In the US, Starbucks, Blockbuster, Hyundai, and thousands of other businesses use census data and GIS software to help them understand what types of people buy their products and services, and how to better market to these consumers. For example, McDonald’s in Japan uses a GIS system to overlay demographic information on maps to help identify promising new store sites. Singapore Management …

An Interface Of Drainage Division For Modeling Wetlands And Riparian Buffers In Agricultural Watersheds

Journal of Spatial Hydrology

In a complex watershed, isolated wetlands, riparian wetlands and riparian buffers provide important functions such as flood attenuation and water quality improvement. For conservation purposes, it is critical to properly delineate drainage areas for these features such that their impacts on runoff, sediment and pollutant transport can be reasonably simulated. However, traditional methods for watershed delineation typically fill depressions or ignore riparian features in order to maintain the continuity of surface flow pattern. In this study we develop an ArcView geographic information system (GIS) interface for watershed delineation that accounts for wetlands and riparian buffers. Based on digital elevation model …

Are Home Values Affected By Sinkhole Proximity? Results Of A Hedonic Price Model, Spencer Fleury Ph.D.

Spencer Fleury Ph.D.

Though they lack the high profile and sheer destructive force of hurricanes, floods, and other natural hazards, sinkholes have on occasion generated significant damage to buildings, roads, and other human-built structures, and should be considered natural hazards in their own right. In sinkhole-prone areas where market insurance against sinkhole damage is available, economic theory suggests that homes located there should be valued somewhat lower than homes located in areas where sinkholes are rare or nonexistent, in recognition of both the risk faced by the homeowner in a sinkhole-prone area, and the cost of insuring one’s property against that risk. Working …

Use Of Geospatial Information And Remote Sensing Data To Support Improved Roadway Access Management, Reginald R. Souleyrette, P. E. Plazak, D. J. Plazak

Reginald R. Souleyrette

Urban and suburban roadways serve two distinct and sometimes conflicting purposes: providing mobility and allowing access to land and land developments. High-level urban roadways (e.g. arterials) should primarily serve mobility needs of travellers and goods. Low level, local roadways should primarily allow for land development access. Arterials that allow too much direct land access fail to function properly in terms of both traffic operations and safety. Such roadways are in need of access management. The operational and safety benefits of access management are impressive; access management has been shown to reduce crash rates on urban and suburban arterials by up …

Distribution And Habitat Characterization Of The Florida Burrowing Owl In Non-Urban Areas, Mark S. Mueller

USF Tampa Graduate Theses and Dissertations

The full geographic distribution and habitat use of the Florida Burrowing Owl, a state "Species of Special Concern," is not well-understood, particularly in remote, non-urban areas. This thesis aimed to expand and improve knowledge about non-urban burrowing owls. We first compiled databases of historic sighting observations. Fieldwork verified and updated existing breeding observation point records and also yielded new breeding locations. Using a GIS, we characterized observed land use, landcover, relevant soil attributes, projected future land use and managed area status for selected points. We quantified landcover within biologically-determined buffer distances around burrows from our own field-verified records. Using standard …

Hydrolgeologic Groundwater Sensitivity And Vulnerability Mapping In South Central Kentucky, Andrea Croskrey

Masters Theses & Specialist Projects

Groundwater sensitivity (Ray and O'dell 1993 a) refers to the inherent ease with which groundwater can be contaminated based on hydrogeologic characteristics. We have developed digital methods for identifying areas of varying groundwater sensitivity for a ten county area of south-central Kentucky relevant to a scale of 1: 24,000. The study area includes extensive limestone karst sinkhole plains, with groundwater that is generally extremely sensitive to contamination. Digitally Vectorized Geologic Quadrangles (DVGQs) were combined with elevation data to both identify hydrogeologic groundwater sensitivity regions and to identify zones of "high risk runoff where contaminants could be transported in runoff from …

Standardizing Geospatial Information For New England Conservation Lands: Data Capture Methods And Technology, Richard Sutton, Sam Merrill

GIS Applications

In 2002 The New England Environmental Finance Center and Applied Geographics issued the Feasibility Study for a GIS Inventory of New England Conservation Lands 1 describing the conservation lands data status throughout EPA Region 1 (New England). This report identified stakeholders and technologies participating in the maintenance of conservation lands data within this region. In the four years since that initial report dramatic changes have occurred in the technical means by which geographic data are delivered from their respective repositories. These changes have been most pronounced and obvious in the area of web mapping services. Web mapping services are software …

Estimating Spatial Sediment Delivery Ratio On A Large Rural Catchment

Journal of Spatial Hydrology

Soil erosion and sediment yield from catchments are key limitations to achieving sustainable land use and maintaining water quality in streams, lakes and other water bodies. Controlling sediment loading requires the knowledge of the soil erosion and sedimentation. However, sediment yield is usually not available as a direct measurement but estimated by using a sediment delivery ratio (SDR). An accurate prediction of SDR is important in controlling sediments for sustainable natural resources development and environmental protection. There is no precise procedure to estimate SDR, although the USDA has published a handbook in which the SDR is related to drainage area. …

Modeling For Management In A Compliance World, Christopher D. Dore, Luann Wandsnider

Department of Anthropology: Faculty Publications

In practice, compliance-driven cultural resource “management” and its requirements for resource location, evaluation, impact assessment, and mitigation manifests a fundamentally different use of geospatial predictive modeling than do research-oriented investigations. This difference primarily results from the lack of an iterative research design. In research-oriented modeling, iterations of model building and model testing gradually build a more robust model and lead to an increased understanding of the variables that condition human spatial behavior in the past. In a compliance environment, spatial models are rarely built and evaluated; rather, once built, they are applied in a single iteration. An assumption is made …

As a newly independent country, East Timor is faced with a number of significant international opportunities, together with some obligations that it must fulfil, including the delimitation of its international boundaries. Similarly, for Indonesia, with 10 maritime neighbours, the delimitation of maritime boundaries is a significant challenge. This paper describes a preliminary study on the delimitation of the Indonesia - East Timor maritime boundary, with a focus on technical aspects. Geospatial data has been obtained from the Indonesian government and processed with …

Delineating Hurricane Vulnerable Populations In Orleans Parish, Louisiana, Stephanie Pedro

LSU Master's Theses

Since settlement first began, equality issues between different social classes have been evident in the location of where residents settled in New Orleans. This research seeks to answer the question: What socioeconomic indicators are prevalent in the areas most-at-risk to flooding which could inhabit populations least able to evacuate? I will use Census 2000 block group data from the socioeconomic sample data (SF3) collected in 2000, along with other economic and GIS data from the New Orleans region to statistically represent the distribution of risk by selecting indicators predicted to be in flood zones from a classification tree analysis. Then, …

Voting With Your Hands: Gis And Experiential Learning, Jeremy W. Donald

Library Faculty Research

Experiential learning is a trend in liberal arts colleges. Students are increasingly asked to learn by tackling problems beyond the classroom, often in the context of the local community. This can mean knowing how to apply technology and quantitative data to analyze and understand a problem, and GIS is a powerful tool for place- and data-based analysis. In concert with the chairs of the Political Science and Sociology departments, the GIS librarian at Trinity University developed a plan for teaching GIS in a semester-long flagship course on election statistics and redistricting in Bexar county. Course design provided users with early …
