Computational Modeling & Simulation Engineering Theses & Dissertations

New capabilities in agent based model (ABM) environments are opening the door to the creation of ABM that may incorporate high-quality, real world environment data in the form of Geospatial Information System (GIS) files . In the past, GJS environments were only possible through extensive software development efforts focused on specific model applications.

This thesis explores the value and issues of using GIS data to provide an ABM environment. It examines the ability of ABM development environments (DE) to support GIS environment data. The selected ABM DE is then used to model population behavior in an environment defined by authoritative …


Wavelet Analysis For Aboveground Biomass Estimate In Temperate Deciduous Forests, Xiaofang Wei Aug 2008

Wavelet Analysis For Aboveground Biomass Estimate In Temperate Deciduous Forests, Xiaofang Wei

All-Inclusive List of Electronic Theses and Dissertations

The ever-increasing concentration of anthropogenic greenhouse gases (C02, CH4, and CFCs) has been identified as a likely (greater than 90% confidence) cause of the observed increase of global mean temperatures since the mid-20th century (IPCC, 2007). The effect of human-induced climate change could be unprecedented and far-reaching. Carbon sequestration into trees and forests is an effective and inexpensive way for mitigating the C02 level in the atmosphere. Hence, accurate measurement of biomass will be of great importance to global carbon cycle and climate change. This study performed a wavelet-based forest aboveground biomass estimation approach in a temperate deciduous forest, the …

"Sustainable Development": Critical Concepts In Geography, Tyler Vick May 2008

"Sustainable Development": Critical Concepts In Geography, Tyler Vick

Geography Masters Research Papers

This paper reviews significant geographic contributions to academic literature in the arenas of conservation, environmental thought, and "sustainable development", in order to understand why geographers have not been more central contributors to the sustainable development movement. A review of geographic literature reveals no lack of understanding on the "sustainable development" concept. However, the disciplines' contributions are lacking in numbers relative to published articles and in developing research and practical methods for directly benefiting the "sustainable development" movement. In fact, only a handful of geographers have made multiple literary contributions on the topic of "sustainable development."

The discipline of geography is …


Comparing Pixel- And Object-Based Classification Methods For Determining Land-Cover In The Gee Creek Watershed, Washington, Tyler Vick May 2008

Comparing Pixel- And Object-Based Classification Methods For Determining Land-Cover In The Gee Creek Watershed, Washington, Tyler Vick

Geography Masters Research Papers

This study analyzes land-cover types in the Gee Creek Watershed of southern Washington using the pixel-based and object-based image analysis approaches. Landsat imagery has traditionally been used for pixel-based classification and change detection in land-cover studies. In recent years, the availability of high-resolution satellite and aerial imagery have enabled for land-cover classification to occur at scales not possible using traditional Landsat imagery. High-resolution aerial imagery of 1 meter or greater has become readily available for free. Yet, commonly found black and white (or panchromatic) aerial imagery is without the multiple spectrum bands found in Landsat imagery, thereby limiting the accuracy …


Automated Vector-To-Raster Image Registration, Boris Kovalerchuk, Peter Doucette, Gamal Seedahmed, Robert Brigantic, Michael Kovalerchuk, Brian Graff May 2008

Automated Vector-To-Raster Image Registration, Boris Kovalerchuk, Peter Doucette, Gamal Seedahmed, Robert Brigantic, Michael Kovalerchuk, Brian Graff

Computer Science Faculty Scholarship

The variability of panchromatic and multispectral images, vector data (maps) and DEM models is growing. Accordingly, the requests and challenges are growing to correlate, match, co-register, and fuse them. Data to be integrated may have inaccurate and contradictory geo-references or not have them at all. Alignment of vector (feature) and raster (image) geospatial data is a difficult and time-consuming process when transformational relationships between the two are nonlinear. The robust solutions and commercial software products that address current challenges do not yet exist. In the proposed approach for Vector-to-Raster Registration (VRR) the candidate features are auto-extracted from imagery, vectorized, and …

Not Your Father’S Border: An Examination Of The Border In Northern Ireland And Its Relevance To The Global Change In The Importance Of World Borders, Aaron Patterson Jan 2008

Not Your Father’S Border: An Examination Of The Border In Northern Ireland And Its Relevance To The Global Change In The Importance Of World Borders, Aaron Patterson

Theses, Dissertations and Capstones

Humanity has long maintained barriers separating specific entities from others. Ranging from cultural, religious, financial, and racial differences among a few others, the reasoning behind borders has remained a purely human endeavor. But our current golden age of technology has somewhat shrunk, or at least reassessed the necessity for borders. The boundaries of today, while many remain in the same locations as in the past, are vastly different from the borders created by previous generations. Globalization, a relatively new term, has made communication simple and fast. The noticeable result has been, of course, better communication between locations, and thus easing …

Through federal regulations, metropolitan planning organizations (MPOs) are mandated to perform public outreach and impact assessment. Although there are some established parameters, the quality and effectiveness of public outreach efforts vary widely, and in many instances information dissemination becomes the central focus of public outreach efforts. However, information dissemination, although essential, is not as effective as a two-way process of public involvement in which members of the public may provide feedback to shape agency initiatives. Research conducted for the Ferry Parking and Landside Access Study is used to describe best practices in public outreach, focusing on socio-economic and community impact …

Geo-Ontology Tools – The Missing Link, Jochen Albrecht, Laxmi Ramasubramanian, Brandon Derman Jan 2008

Geo-Ontology Tools – The Missing Link, Jochen Albrecht, Laxmi Ramasubramanian, Brandon Derman

Publications and Research

Numerous authors have presented ontology building tools that have all been developed as part of academic projects and that are usually adaptations of more generic tools for geo-spatial applications. While we trust that these tools do their job for the special purpose they have been built, the GIScience user community is still a long way away from off-the-shelf ontology builders that can be used by GIS project managers. In this article, we present a comparative study of ontology building tools described in some twenty peer-reviewed GIScience journal articles. We analyze them from the perspective of two application domains, crime analysis …

The urban landscape is an interspersed mixing of residences, shops, theaters, parks, natural areas, and a multitude of other uses. From the early days of the central markets, to the planned downtown, to the heavily planned super-regional shopping complexes, commercial landscapes evolve. There has been considerable research conducted on analyzing the commercial structure of urban environments in an attempt to better understanding the nature of retailing and its resultant impacts on the geography of the city.

This research has three broad goals: a) to develop a technique that makes operational, in a systematized and objective manner, an approach to analyzing …


Using Gis To Optimize The Design And Implementation Of The Rtk Reference Network In Abu Dhabi, Mustafa Abdulla Almusawa Dec 2007

Using Gis To Optimize The Design And Implementation Of The Rtk Reference Network In Abu Dhabi, Mustafa Abdulla Almusawa

Theses

Several challenging applications and construction works demand real-time measurements for positioning at the centimeter-level accuracy. This positioning accuracy can be obtained by using a Global Positioning System (GPS) roving unit and employing a single reference station (base-station) or through utilizing the service of multiple reference stations forming a Real-Time Kinematics (RTK) Reference Network.

The limitation of the single reference approach is that measurement errors are distance dependent and good accuracy can be only obtained when distances are less than 10 kms. In addition, this method requires a nearby Geodetic Control Point (GCP). Recently, RTK reference networks are widely established in …

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. …
