All-Inclusive List of Electronic Theses and Dissertations

The objective of this research is to develop cost-effect and accurate methods to identify optimal restorable drained wetland cropland sites. Landsat Thematic Mapper (TM) data analysis was used to identify the potential cropland candidate sites in the initial step. The result of digital TM data analysis shows that the overall classification accuracy in identifying classes of potential restoration candidate hydric soils is 86.7%. This accuracy shows that the TM data digital analysis is a cost-effective method for identifying poorly drained cropland hydric soils potentially suitable for wetland conversiOn. To support multi-factorial analysis in the final site screening, a Spatial Decision …

Gis Enhancements Using Gps Technology, Marc R. Beckel

Dissertations and Theses

Global Positioning System (GPS) technology is a viable tool for the collection and creation of Geographic Information System (GIS) databases. Organizations have turned their attention to using this tool to develop new databases for their existing GIS. The integration of these new GPS derived databases with older existing databases leads to both technical and organizational repercussions. With the integration of GPS derived data, an organization's existing GIS requires enhancements to GIS databases and the organization must be prepared to manage the integration.

This thesis examines the technical issues that occur due to integration and conflation of GPS data in an …

Monitoring Cattle Behavior And Pasture Use With Gps And Gis, L. W. Turner, M. C. Udal, B. T. Larson, S. A. Shearer

Management and Monitoring of Farm Animals Collection

Precision agriculture is already being used commercially to improve variability management in row crop agriculture. In the same way, understanding how spatial and temporal variability of animal, forage, soil and landscape features affect grazing behavior and forage utilization provides potential to modify pasture management, improve efficiency of utilization, and maximize profits. Recent advances in global positioning system (GPS) technology have allowed the development of lightweight GPS collar receivers suitable for monitoring animal position at 5-min intervals. The GPS data can be imported into a geographic information system (GIS) to assess animal behavior characteristics and pasture utilization. This paper describes application …

Spatial Modeling In Emergency Medical Systems: Analysis Of A Regional Trauma System With Two Centers, Christopher A. Bangs

Dissertations and Theses

The allocation of trauma patients to one of two trauma centers based on multiple criteria presents significant challenges in modeling network-based solutions for Emergency Medical Services (EMS). Capabilities in a desktop Geographic Information Systems (GIS) include spatial analysis and map visualizations that contribute to improved understanding of EMS and the trauma allocation. Using a common desktop GIS application and a statistical analysis application, key spatial and temporal characteristics of both penetrating and blunt trauma are described, and the EMS allocation system is analyzed.

As a sub-group of all emergencies, trauma-system patients represent the most severely injured. Understanding the spatial-temporal distributions …

Crop-Raiding Elephants And Conservation Implications At Way Kambas National Park, Sumatra, Indonesia, Philip J. Nyhus, Sumianto, Ronald Tilson

Faculty Scholarship

Crop raiding by wild elephants is one of the most significant sources of park–people conflict in Sumatra, Indonesia. The distribution, impact and conservation implications of elephant crop-raiding in 13 villages that border Way Kambas National Park in southern Sumatra were studied for 18 months. The data are based on rapid village and field assessments, data logs maintained by village observers and a quantitative household survey. Elephants raided crops year-round at a mean rate of 0.53 elephants per day for the entire study area. The frequency of crop raiding was related to vegetation type along the park border, the size and …

Using Gis To Model The Timbershed Of A Wood Based Manufacturing Facility, Robert Brewington, Richard A. Williams, Jeffery Earl

Journal of the Arkansas Academy of Science

A geographic information system (GIS) is an excellent tool for determining timber procurement zones. This study focuses on the procurement zones of two wood processing facilities in Arkansas, one in Fort Smith and one near Menifee. Since the two mills began operation in 1995, there have been questions about the long-term effect on the hardwood timber resource of the region. The "wood basket" for these mills must first be determined before their effects can be studied. Transportation from the harvest site to the primary processing facility accounts for a large portion of the total mill-delivered cost for raw material and …

Field Interpretation Of Latitude And Longitude In Arkansas: A Portable Coordinate Projection, William R. Teague

Journal of the Arkansas Academy of Science

Two- and three-dimensional coordinate systems are fundamental to most quantitative mapping applications. The Geodetic, Universal Transverse Mercator (UTM),and State Plane systems have traditional roles in various science, surveying, and government agency engineering applications. The coordinates of three-dimensional Geodetic system are latitude, longitude, and height above ellipsoid (HAE).Because of its ability to cope with the intrinsically three dimensional character of the earth's surface, the Geodetic system is capable of supporting precise relative positioning and very high accuracy computations of distance between any two positions on or near the earth's surface. The two-dimensional UTMand State Plane systems are extremely useful for the …

Method To Predict The Potential Regional Long-Term Timber Supply Using Gis And Other Publicly Available Data, Jeffery Earl, Richard A. Kluender, Robert Brewington

Journal of the Arkansas Academy of Science

While the global demand for wood products is on the rise, timber production has shifted from the Pacific Northwest to the southeastern United States in recent times. The increase in harvesting makes accurate assessment of the South's wood supply essential. Anew method is proposed for looking at the potential supply of raw woody material. The test area was three southeastern Arkansas counties. A geographic information system (GIS) using ArcView software incorporates two sources of public information. First, Forest Inventory and Analysis (FIA) data from the USDA Forest Service were queried to find land areas and volumes by timber type, as …

Shoreline Bluff Failures: A Gis Assessment Of Susceptibility And Risk For Lake Erie's North Central Shore (Ontario), Nathan Joel Badger

Theses and Dissertations (Comprehensive)

One of the characteristic features of the north shore of Lake Erie is its steep, eroding bluffs. Combined with an increase in human presence and pressures at the shoreline, the failure of these slopes has become hazardous. Over the past two decades alone, slope failures have been responsible for millions of dollars of damage to shoreline property, as well as the deaths and near deaths of a number of individuals. Despite the seriousness of this hazard, few studies have identified specific hazard areas and their associated risk of failure along Lake Erie's north shore, and other reaches in the Great …

Working Towards A Cartographic Lexicon: The Role Of Units, Structure, Content, And Expression In Geographic Information, Michael Charles Fabbri

Theses and Dissertations (Comprehensive)

This thesis was conceived from an interdisciplinary perspective towards the advancement of cartographic research and geographic education. The primary focus is to understand the cognitive process of cartographic communication as an approach both to improvements in design and to teaching and learning of the cartographic language. Specifically, it attempts to understand more about how the map functions. It accepts that the map is a functional graphic display, whose main purpose is to represent, communicate, and store geographical information, which allows a focus on what that geographical information is conceptually. The essential goal of map use is geographic comprehension, and if …
