Naturalized Daily Streamflow Reconstruction For The Upper Wabash River, Sanoar Rahman, Laura C. Bowling

Purdue GIS Day

During the 1960s, the United States Army Corps of Engineers constructed a number of dams in the Upper Wabash watershed in Indiana, primarily for flood control, hydropower and recreation. In order to investigate the impact of other environmental changes, such as changes in land management and climate on streamflow, it is necessary to reconstruct what the natural flow of the impounded river would be without the influence of the upstream reservoirs.

Indiana Freshwater Use Projection And Spatial Analysis For Renewable Water Supply, Sanoar Rahman, Laura Bowling

Purdue GIS Day

Often, when governmental and non-governmental entities attempt to make plans for future water supply and environmental flows they fall into the trap of developing strategies for specific locations rather than working together and approaching a problem from a basin or regional scale. The problem persists when lack of knowledge of local situations and confining management plans with city and county lines merge together. The purpose of this study is to project future water use and then to reveal if there is any pattern in renewable water supply in Indiana to provide a basis for policy makers and stakeholders to consider …

Ethnographic Collector, Gideon Singer

Purdue GIS Day

Ethnography can be enhanced by utilizing both ArcGIS Online and Arc Collector. Throughout 2015, I have designed and utilized the Ethnographic Collector web map to record qualitative observations, spatial records, and multi-media attachments. Data was recorded while conducting pilot research on the e-waste landscape of Tippecanoe County, Indiana and a class ethnography project on the neighborhood of New Chauncey. The Ethnographic Collector has augmented qualitative data collection via participant observation and go-along interviews and can likely be utilized in tandem with participatory GIS.

Characterizing And Mapping The Field Scale Spatial Variability Of Surface Horizon Soil Properties And Water Content With Noninvasive Em38, Ryan W.R. Schroeder, Robert Austin, Joshua Heitman, Adam Howard

Purdue GIS Day

The spatial variability of physical soil properties at the field scale is increasingly important in agriculture and natural resource management. Changes in topography, parent material, management practices, erosion/deposition rates, etc. can influence the variability of the soil’s physical properties and help guide management and land use plans. The Geonics EM38 is a noninvasive geophysical sensor which is used to measure the apparent electrical conductivity (ECa) of the soil through electromagnetic induction – primarily influenced by clay content, soil moisture content, and salinity. Soil moisture has been found to be a significant contributor to ECa and is therefore useful in determining …

China's Nine-Dashed Map: Continuing Maritime Source Of Geopolitical Tension, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The South China Sea (SCS) is becoming an increasingly contentious source of geopolitical tension due to its significance as an international trade route, possessor of potentially significant oil and natural gas resources, China’s increasing diplomatic and military assertiveness, and the U.S.’ recent and ongoing Pacific Pivot strategy. Countries as varied as China, Taiwan, the Philippines, Indonesia and other adjacent countries have claims on this region’s islands and natural resources. China has been particularly assertive in asserting its SCS claims by creating a nine-dash line map claiming to give it de facto maritime control over this entire region without regard to …

Les Rues Des Tableaux. Géographie Du Marché De L'Art Parisien (1815-1955), Léa Saint-Raymond, Félicie De Maupeou, Julien Cavero

Artl@s Bulletin

Continuation of a first socioeconomic analysis of the "art dealers" in Paris between 1815 and 1955 (Artl@s Bulletin 2, no. 2), this paper presents the results of a spatial study of the Parisian art market at that time. Departing from serial geographical data given by a homogeneous source, the Bottin du commerce, we mapped a 140 years spatial evolution of the "art dealers", using a geocoding system with composite locators. The article exposes the spatial dynamics of this market and studies them in a multi-scalar way, making the connection between the global evolution of the Parisian economy and …

A Research-Based Model For Digital Mapping And Art History: Notes From The Field, Paul B. Jaskot, Anne Kelly Knowles, Andrew Wasserman, Stephen Whiteman, Benjamin Zweig

Artl@s Bulletin

Most digital mapping in art history today divides the research process from the visualization aspects of the project. This problem became the focus of a summer institute that Paul Jaskot and Anne Kelly Knowles ran at Middlebury College with the support of the Samuel H. Kress Foundation. Our article both reports on the institute and suggests how research questions can complement digital mapping methods. We conclude with three case studies of spatial questions in art history and discuss the Fellows’ use of GIS to explore examples from Qing Dynasty China, medieval Gotland, and contemporary New York City.

Waste And Duplication In Nasa Programs: The Need To Enhance U.S. Space Program Efficiency, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The U.S. Government faces acute budgetary deficits and national debt problems in the Obama Administration. These problems have been brought about by decades of unsustainable government spending affecting all agencies including the National Aeronautics and Space Administration. (NASA). An outgrowth of this fiscal profligacy is the presence of wasteful and duplicative programs within NASA that prevent this agency from achieving its space science and human spaceflight objectives. These problems occur due to mismanagement of these programs from NASA and the creation of these programs by the U.S. Congress and congressional committees. This occurs because congressional appropriators tend to be more …
