Enhancement Of Cots Gis Web Publishing Software, Jin Chen

University of New Orleans Theses and Dissertations

In the modern geographic information systems, COTS software has been playing a major role. Customizing COTS software is inevitable because large organizations' needs usually exceed COTS built-in functions. However, this is often a challenge to COTS users, since the source code of COTS is rarely available. In my thesis project, I have enhanced some functions of a GIS COTS product, ArcIMS, by taking advantage of this web publishing tool's well-thought architecture of services and its applications of the XML messaging technology. Multiple users now can access the same ArcIMS map service but with only constrained viewing power. Login dialog has …

The goal of the project is to create high-definition maps that will include the identification of mined areas and their socio-economic and security implications, as well as the development of GIS training capabilities so that the project can be locally supported.

A.M.I.S. And The Partitioning Of Preference, Ted H. Grossardt

Kentucky Transportation Center Presentations

This presentation reviews work by the researchers that combines group dialogic techniques with analytic hierarchy and GIS to bring the knowledge of large groups of people to bear on a highway routing problem. A significant question is how technical knowledge and local information can be combined, either dialogically or mathematically, to provide the most faithful and practical version of a collaborative preference surface, what we call the Analytic Minimum Impedance Surface, or AMIS. While all preferences can be summed directly for this purpose, it may be more accurate and effective to partition the preference contribution to the landscape by knowledge …

A Spatial Technique For Estimating Streambank Rosion Based On Watershed Characteristics

Journal of Spatial Hydrology

A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This technique relies on the use of data sets that are easily obtained and expressed as GIS data layers. The basis of this technique are statistical relationships between “lateral erosion rates” and watershed characteristics such as curve number, grazing animal density, topographic slope, soil erodibility, and degree of urban development. An algorithm for estimating streambank erosion was incorporated into a GIS-based watershed model. Simulated and observed sediment loads were compared for twenty-eight …

Spatially Distributed Watershed Mapping And Modeling: Gis-Based Storm Runoff Response And Hydroraph Analysis: Part 2

Journal of Spatial Hydrology

Advances in scientific knowledge and new techniques of remote sensing permit a better understanding of the physical land features governing hydrologic processes, and make possible efficient, large-scale hydrologic modeling. The need for land-cover and hydrologic response change detection at a larger scale and at times of the year when hydrologic studies are critical makes satellite imagery the most cost effective, efficient and reliable source of data. In this work, remotely-sensed data and geographic information system (GIS) tools were used to estimate the changes in runoff response for three watersheds (Etonia, Econlockhatchee, and S-65A sub- basins) in Florida. Land-use information from …

Construction Of Digital Elevation Models For Archaeological Applications, Jon B. Hageman, David A. Bennett

Anthropology Faculty Publications

The use of interpolation in archaeology is becoming common. As archaeologists incorporate geographic information systems (GIS) and computer mapping programs into their research, questions of interpolation become fundamental considerations in the representation and manipulation of topographic data. To date, however, few archaeologists have dealt with these questions. Uncritical use of interpolation algorithms can result in unrealistic representations of the landscape in a mapping program or can result in an inaccurate digital elevation model (DEM) used in a GIS. This, in turn, can lead to an ineffective predictive model of site location. By carefully selecting an interpolation algorithm that is well …

Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips

All Master's Theses

The settlement patterns of the prehistoric inhabitants of the Columbia Plateau were choreographed to match the cadence of the seasons, with movements timed to efficiently utilize available resources. Desert roots, such as lomatium and bitterroot, provided a primary source of dietary nutrition, yet the ideal conditions for exploiting these plant resources coalesced for a very limited time in any one location. It was therefore necessary to possess an intimate knowledge of the plants' lifecycles in order to effectively plan gathering activities. In order to predict the growth patterns and maturation rates of these desert root crops, a GIS model was …

Monitoring Harbor Dredging And Sedimentary Changes In Coastal Habitats Of The Santa Cruz Bight, California, Steven G. Watt

Capstone Projects and Master's Theses

A unique case-study was conducted in Santa Cruz, California that included an experimental harbor dredging event into the natural framework of a dynamic, coastal environment. The Santa Cruz Harbor was permitted to dredge mixed sand and mud sediment into the surf-zone at Twin Lakes Beach. This fine-grained dredging experiment is the first of its kind in California. A challenge to the EPA's "80/20" rule which states that dredged (non-toxic) sediment released into the surf-zone should contain at least 80% sand-sized material.

Development Of Gis As An Information Management System: A Case Study For The Burden Center, Zhitao Su

LSU Master's Theses

For a park site, it is very important and necessary to let the local planning authorities realize and understand the important aspects and benefits of the site and to establish the long-range development strategies for the location. In order to succeed during the planning process, the communication and information that flow among all the participants must be well organized. In this situation, a project-wide Geographic Information System (GIS) would be a good solution. The goal of this project is to explore the possibilities for administrative authorities to implement a GIS database system to support the site planning and management of …

Gateways Into The Atchafalaya: Developing A Framework For Water-Based Recreation In The Atchafalaya Basin Parishes, Steven Joseph Lumpkin

LSU Master's Theses

The term “gateways” has been used in many contexts as a means of providing entry or connection. Gateways are where people congregate to leave a realm of familiarity to one of uncertainty and adventure. They can also mark the entrance into an area of interest. Gateways may have a significant impact on an individual’s impression of a particular destination. This thesis provides arguments for using boating gateways into the Atchafalaya Basin (AB) region as the basis for a recreational framework that encompasses eight parishes. A common theme that exists in all eight AB parishes is their boat launches. They represent …

Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally

LSU Master's Theses

It is important to be able to predict the potential spread of water borne diseases when building dams or redirecting rivers. This study was designed to test whether the use of a growing degree day (GDD) climate model and remotely sensed data (RS) within a geographic information system (GIS), could be used to predict both the distribution and severity of Schistosoma haematobium. Growing degree days are defined as the number of degrees centigrade over the minimum temperature required for development. The base temperature and the number of GDD required to complete one generation varies for each species. A monthly climate …

Fractal Compression And Analysis On Remotely Sensed Imagery, Ke Xiao

LSU Doctoral Dissertations

Remote sensing images contain huge amount of geographical information and reflect the complexity of geographical features and spatial structures. As the means of observing and describing geographical phenomena, the rapid development of remote sensing has provided an enormous amount of geographical information. The massive information is very useful in a variety of applications but the sheer bulk of this information has increased beyond what can be analyzed and used efficiently and effectively. This uneven increase in the technologies of gathering and analyzing information has created difficulties in its storage, transfer, and processing. Fractal geometry provides a means of describing and …

Models For The Distribution Of Quaking Aspen In Geographic And Potential Evapotranspiration Spaces Relevant To The Book Cliffs (Utah), 2000-2002, Joseph O. Sexton

Aspen Bibliography

Quaking aspen is the most widely distributed tree species in North America and an asset to sociological, ecological, and hydrological land values in the western United States. In recognition of these values, land managers seek means to oppose a regional decline of aspen in the Intermountain West—a decline apparently in progress since the close of the Pleistocene and driven by climate change, fire suppression, and increasing ungulate densities. One location of special relevance to this decline is the Utah-Colorado Book Cliffs, a discrete boundary of quaking aspen’s geographic range and a potential biogeographic corridor between the sub-alpine communities of the …
