Mapping The Landscape For Archaeological Detection, Preservation, And Interpretation: A Case Study In High Resolution Location Modeling From The Blue Mountains Of Northeastern Oregon, Trent Skinner
UNLV Theses, Dissertations, Professional Papers, and Capstones
Archaeological location modeling (ALM) is an important tool in most survey strategies, and has contributed substantially to economizing efforts to locate and characterize the archaeological record. The increasing availability of high resolution (<3m) airborne light detection and ranging (lidar) data has the potential to refine the application and ultimately the role of ALM. This research tests the precision and accuracy gained by incorporating lidar derived data into an ALM. The site records and other environmental data used in this study were all generated over the last four decades by the resource specialists of the Malheur National Forest. The Weights-of-Evidence (WofE) probability method (Bonham-Carter 1994) was used to produce two ALMs; one based on a 10m digital elevation model (DEM) created from satellite imaging, and the second from a 3m resolution lidar derived DEM. Independent variables (e.g., slope, aspect, distance to water, etc.) commonly used in ALM were largely replaced by index variables (e.g., slope position classification, topographic wetness index, etc.). The final models were classified into areas of high, medium, and low archaeological potential, then cross-validated against a reserved random dataset. Models were then compared using the Kvamme gain statistic and site to area frequency ratio. The 3m model demonstrated a significant improvement over the results obtained from the 10m model and the current probability model used in the study area. A number of factors including model resolution, statistical methodology, and the character of the independent and dependent variables all contributed to the increase in precision and accuracy. The incremental improvement in modeling efficiency demonstrated here will create time and cost saving in the management and preservation of cultural resources, and ultimately contribute to a better understanding of patterns of past human land use.

Gis Investigation Of Crime Prediction With An Operationalized Tweet Corpus, Anthony J. Corso, Abdulkareem Alsudais
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Social media as the de facto communication channel is being used to disseminate one’s diurnal self-revelations. This profound discovery often contains double-talk, peculiar insights, or contextual information about real-world events. Natural language processing is regularly used to uncover both obvious and latent knowledge claims within disclosures published amid the complex environment. For example, a perpetrator with first-hand knowledge of their criminal incident uses social media to post critical information about it. A geographic information system (GIS) is capable of large-scale point data analysis and possesses methods that enable dataset processing, evaluation, and automatic spatial visualization. Such an artifact—fused with traditional …

Geographic Information Systems (Gis) And Predictive Modeling Of Body Disposal Sites, Annemarie Catherine Gundel
Geographic Information Systems (Gis) And Predictive Modeling Of Body Disposal Sites, Annemarie Catherine Gundel
Masters Theses
Homicide victims are often discovered by accident or located through witness testimony, both of which are unreliable methods. Moving a victim’s body from the scene of the crime to a secondary disposal site may further complicate their discovery, delaying recovery, identification, and evidence collection. Homicides are exponentially more difficult to investigate, solve, and prosecute without a body. In the medicolegal context, a body disposal site prediction model is an alternative to relying on luck or witness testimony. Predictive models were created using body disposal data collected from the Office of the Chief Medical Examiner (OCME), Connecticut, to explore the feasibility …
Using Mobile Geographic Information Systems To Improve Operational Efficiency, Data Reliability, And Access In Mine Action, Paul Rittenhouse, Lindsay Aldrich
Using Mobile Geographic Information Systems To Improve Operational Efficiency, Data Reliability, And Access In Mine Action, Paul Rittenhouse, Lindsay Aldrich
The Journal of Conventional Weapons Destruction
The inherently complex field of mine action, with its many political, financial, and physical considerations, is also a spatial, data-driven field; and as a result, geographic information systems (GIS) stand to play a major role. Spatial data can help address questions such as: Where are the hazardous areas and what has been cleared or cancelled? Where have teams already surveyed? Where should they go next? How many square meters have been cleared? Due to the complexities surrounding assigning tasks and prioritization, standard operating procedures (SOP), quality assurance/quality control (QA/QC) and database design, GIS often gets limited to high-level planning, database …

A Landscape Of Water And Waste: Heritage Legacies And Environmental Change In The Mesabi Iron Range, John Baeten
A Landscape Of Water And Waste: Heritage Legacies And Environmental Change In The Mesabi Iron Range, John Baeten
Dissertations, Master's Theses and Master's Reports
This dissertation explores the intersection between mining technology, industrial heritage, and environmental history, using iron mining in the Mesabi Range of the Lake Superior Iron District as its core case study. What impact did technological shifts in iron mining and ore processing have on the environment of the Lake Superior basin? How did the environmental changes wrought from low-grade iron ore mining and processing, such as the expansion of open-pits and the production of tailings, affect different communities in Minnesota’s Mesabi Range? And finally, how have the environmental legacies of iron mining been remembered and memorialized, or ignored and forgotten?
Evaluating The Potential Of A Geospatial/Geostatistical Methodology For Locating Rain-Derived Infiltration And Inflow Into Wastewater Treatment Systems In The Minneapolis/St. Paul Metropolitan Area, Minnesota, Usa, Vinson Aaron Williams
All Graduate Theses, Dissertations, and Other Capstone Projects
A significant issue facing municipal wastewater treatment infrastructure (WWTI) is how to manage infiltration and inflow (I/I). I/I of rain and ground water permeate into WWTI after precipitation events, periods of groundwater table rise, and percolation from surrounding surface waters. This can create discharges above the infrastructure's flow capacity, increase costs for processing the wastewater and add undesired stress to aging wastewater networks. In an attempt to assess this problem cost and time inefficient approaches have commonly been applied. This study utilizes a new and more radical methodology to try and make WWTI management more efficient. This study applies ArcGIS …
