The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi
Department of Anthropology: Faculty Publications
There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

Design And Interpretation Of Intensity Analysis Illustrated By Land Change In Central Kalimantan, Indonesia, Robert Gilmore Pontius, Yan Gao, Nicholas M. Giner, Takashi Kohyama, Mitsuru Osaki, Kazuyo Hirose
Geography
Intensity Analysis has become popular as a top-down hierarchical accounting framework to analyze differences among categories, such as changes in land categories over time. Some aspects of interpretation are straightforward, while other aspects require deeper thought. This article explains how to interpret Intensity Analysis with respect to four concepts. First, we illustrate how to analyze whether error could account for non-uniform changes. Second, we explore two types of the large dormant category phenomenon. Third, we show how results can be sensitive to the selection of the domain. Fourth, we explain how Intensity Analysis' symmetric top-down hierarchy influences interpretation with respect …

A Suite Of Tools For Roc Analysis Of Spatial Models, Jean François Mas, Britaldo Soares Filho, Robert Gilmore Pontius, Michelle Farfán Gutiérrez, Hermann Rodrigues
Geography
The Receiver Operating Characteristic (ROC) is widely used for assessing the performance of classification algorithms. In GIScience, ROC has been applied to assess models aimed at predicting events, such as land use/cover change (LUCC), species distribution and disease risk. However, GIS software packages offer few statistical tests and guidance tools for ROC analysis and interpretation. This paper presents a suite of GIS tools designed to facilitate ROC curve analysis for GIS users by applying proper statistical tests and analysis procedures. The tools are freely available as models and submodels of Dinamica EGO freeware. The tools give the ROC curve, the …

Measuring The Temporal Instability Of Land Change Using The Flow Matrix, D. S.M. Runfola, Robert Gilmore Pontius
Geography
This article introduces the Flow matrix, which expresses the sizes of transitions among categories between two time points. We use the Flow matrix to create a metric R that measures the instability of annual change among time intervals that partition the time extent. Specifically, R is the proportion of change that would need to be reallocated to different time interval(s) to achieve uniform change during the time extent. This article computes R for 10 Long Term Ecological Research (LTER) sites and for seven case studies from published land change data. Of the 10 LTER sites analyzed, the Andrews site in …

Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin
Doctoral
The increasing availability of abundant geographically referenced information in the Geospatial Web provides a variety of opportunities for developing value-added LBS applications. However, large data volumes of the Geospatial Web and small mobile device displays impose a data visualization problem, as the amount of searchable information overwhelms the display when too many query results are returned. Excessive returned results clutter the mobile display, making it harder for users to prioritize information and causes confusion and usability problems. Mobile Spatial Interaction (MSI) research into this “information overload” problem is ongoing where map personalization and other semantic based filtering mechanisms are essential …

Using Dendrochronology To Identify An Unknown Earthquake, Douglas Metcalf, Dr. Matthew Bekker
Journal of Undergraduate Research
Geologists use various dating techniques to determine the ages of geologic phenomena. Dendrochronology- the analysis of annual growth-rings in trees- is one of these methods (Stoffel and Bollschwieler, 2008). Unlike other dating procedures, it can determine the exact years in which various events occurred. Such events include earthquakes, which produce distinct responses in tree-ring growth patterns (Jacoby, 1997).

Local Ordinances That Promote Physical Activity A Survey Of Municipal Policies In Utah, Trenton Robertson, Dr. Shuanna K. Burbidge
Journal of Undergraduate Research
The Utah Department of Health revisited a study published in 2003 in the American Journal of Public Health because they desire to understand how Utah cities are using local laws to encourage or discourage physical activity of residents. Since 2003 only Hawaii has conducted a similar study. We have had the chance and opportunity to refine and perfect methods previously used to research and analyze issues that many other states may use in the next decade.

Dendroarchaology: Using Tree Rings To Document Utah’S Historic Pioneer Structures, Robert Karl, Dr. Matthew Bekker
Journal of Undergraduate Research
Pioneer history is a heritage of Utah. Utah was founded on the premise of pioneers venturing from the east and settling throughout Utah. Very few of these historic pioneer structures have been dated in the state of Utah and for many of these structures there exists only a rough idea of when they were built. Other structures have been dated but the information is unpublished and therefore unavailable to the general public and the scientific community. And, though the use of tree rings in archaeology has a rich history in the southwestern United States , most research has focused on …

Trends In The Spatial Distribution And Characteristics Of Korean-Americans, Megan Knowles, Dr. J. Matthew Shumway, Ruth Kerry
Journal of Undergraduate Research
In Human Geography minimal research has been done regarding the immigration and spatial distribution of Korean-Americans. Historically there has been a detectable relationship between the degree of spatial concentration of a specific population and their degree of social assimilation. Few studies have been conducted regarding Korean-Americans as a separate ethnic group, and these studies most often focus on economic, health, and cultural aspects of the community and tend to be more local in scale.

Arizona v. California at 50: The Legacy and Future of Governance, Reserved Rights, and Water Transfers (Martz Summer Conference, August 15-16)
The Colorado River is an economic, environmental and cultural lifeline of the southwestern United States, and the allocation of its scarce waters are a source of ongoing controversy. This year marks the 50th anniversary of the Supreme Court decision in Arizona v. California. While the case was an important landmark in the still-evolving relationship between these two Lower Basin states, it remains most relevant today by the way in which it clarified federal rights and responsibilities. This is especially true in the areas of federal (including tribal) reserved rights, the role of the Interior Secretary in Lower Basin water …

Investigating The Housing Market For Student Tenants Surrounding An Urban University, Olivia M. Dobbs Ms.
Honors College Theses
The private housing market for students around Wayne State University, an urban campus in Detroit, Michigan, stands in a fast-changing period. The area has grown economically from institutional and medical center investment in the past few years, causing occupancy and rents to rise. This follows years of disinvestment that allowed rent rates to fall to comfortable rates for students. The University has published its interest in developing the “campus life” including more off-campus private market housing for students, while developers see potential for even higher rents for young professionals. This study assesses the current perceptions of a sample of rental …

A Paleoenvironmental Investigation Of Eolian Influx In Lacustrine Sediments Of The Southern Rocky Mountain Region, Rebecca L. Brice
Electronic Theses and Dissertations
Potential indications of long-term trends in paleoclimate, specifically winds, in the Southern Rocky Mountain region of the United States were tested using lacustrine sediment from South Blue Lake in the Wet Mountains of Colorado. This study builds upon existing eolian and lacustrine research, and investigates paleowind in a location not yet studied in this manner. Variability in sediment laminae, particle size, and mineralogy show similar patterns during the mid-Holocene warm period (ca. 5500 cal. yr BP - ca. 6000 cal. yr BP). These patterns indicate a warmer, drier, windier period that is contrasted by a less variable period in the …

The Use Of The Ostracode Cyprideis Americana (Sharpe) As A Proxy For Salinity In Bahamian Lake Systems, Rachel E. Bowles
Masters Theses & Specialist Projects
Ostracodes, bi-valved crustaceans, are potentially excellent proxies for salinity.They are abundant, react to changes in salinity, and secrete low-magnesium calcite shells that preserve information about their host water chemistry. Changes in valve trace element concentration, stable isotope composition, and sieve pore shape values have been linked to changes in salinity. This study analyzed the response of the euryhaline ostracode, Cyprideis americana, to salinity in six lakes from two Bahamian islands across two seasons. The purpose of this work was to determine which compositional and morphological variables in C. americana are the most useful for paleosalinity reconstructions.Ostracode and water samples were …

Banking On The Impossible: The Political Life Of Wetlands In Southern Louisiana, Michael Kantor
Geography and the Environment - Theses
Wetland banking is an increasingly prominent environmental governance strategy in the United States. Associated with larger trends toward the financialization of ecosystem services, wetland banking acts as a mode of social regulation while stabilizing a particular regime of accumulation. Its use by the Army Corps of Engineers and the Environmental Protection Agency to regulate the development of wetlands has certain implications for the distribution of and access to land, water, and capital. This thesis investigates a particular wetland development project in southeastern Louisiana and its relation to a local wetland bank, the Army Corps of Engineers, and a multinational oil …
