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.

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.

Human Mobility Patterns Probability Measurement: An Example Using Twitter Data At Purdue, Yuqian Huang

Purdue GIS Day

Nowadays, social tools are really important to people's daily lives. And it is also valuable to data researcher that Twitter, Facebook and other social tools are emerging as a key resource of free and open volunteered geographic information (VGI). And this research is trying to take advantages of twitter data around Purdue campus. It tracks the most active twitter users in order to find out their behavior patterns and to provide probability of when and where the users will show up.

Summer Internships In Software Engineering In Abe, Larry Theller

Purdue GIS Day

We discuss the various software engineering projects which were assigned to a group of 8 undrgrad computer science interns who worked in Agricultural and Biological Engineering this summer. All projects involved mapping, mobile apps, REST services or online map-based decision support services. All students completed soem ESRI Virtual Campus training.

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 …

Habitat Selection Of Wolverines: A Geospatial Analysis Of Wolverine Movements In Southwest Montana, Bryn Karabensh

Geography and the Environment: Graduate Student Capstones

Wolverine research in the contiguous United States is not abundant and understanding of the ecology of this species is not fully understood in this ecosystem. Specifically lacking in research is data regarding wolverine movements. This paucity of data and analysis inhibits the ability to effectively develop and implement conservation and management strategies. This paper seeks to identify patterns and habitat preferences of wolverines with respect to their movements. Specifically, do they avoid roads and clear-cuts zones from timber harvest and do they display a preference to topography features during movements? Using GPS locations of wolverines a regression analysis was applied. …

Applying Voronoi Tessellations As A Non-Orthogonal Grid Methodology To Inform Public-Private Mix Efforts In Nigeria: An Examination Of The Distribution Of Private Healthcare Providers In Six States And The Covariates Underlying Their Utilization, Trinadh Dontamsetti

USF Tampa Graduate Theses and Dissertations

TB care and prevention is led by the public sector, but many TB symptomatics first seek care in the private sector, highlighting the importance of engaging these facilities. This report examines basic TB epidemiology (such as the gap in case finding that could be addressed in part via private sector activities), health-seeking behaviors (HSB) and diagnostic delays, the size of the private sector, activities of professional societies, and financing. It examines the potential utility of integrating Voronoi tessellations as a GIS-based method for informing and improving Public-Private Mix (PPM) efforts throughout six states in Nigeria. Further, it explores a potential …

Selection Of A Reanalysis Meteorological Product For Use In Solar Resource Assessment, Anthony Lopez

Geography and the Environment: Graduate Student Capstones

The U.S. Department of Energy’s National Renewable Energy Laboratory and collaborators are updating the National Solar Radiation Database with the next-generation satellite-based solar resource assessment known as the Physical Solar Model (PSM). This is part of an effort to achieve NREL and DOE’s goal to make solar energy technologies cost competitive with other forms of energy in the United States. Required in this effort is the selection of an appropriate meteorological reanalysis product- that provides critical inputs for solar energy estimation. This analysis quantitatively and qualitatively assessed the spatial and temporal accuracy of three meteorological reanalysis products using ground measurements. …

Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart

Sinkhole Conference 2015

Karst groundwater contamination presents great challenges for efficient monitoring because of rapid, discrete transport and the diversity of contaminants. Here a low cost approach is described and applied to Hidden River Cave, Kentucky, where a long history of contamination has been experienced. Local knowledge was acquired through informal interviews and coupled with observations of contaminant residues, faunal distributions and fluorescence spectra in the cave. The resulting patterns were interpreted using Google Earth and Street View to identify specific contaminant sources in the affected sub-catchment of the cave. Despite success in matching contaminant sources with the contamination history and pattern, the …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …

Online Mapping Tools For Geolocating Amish Settlements, Andrew M. Wilson, Brian J.B. Lonabocker, Megan E. Zagorski

Environmental Studies Faculty Publications

This technical note demonstrates the value of using online mapping tools as a method of geolocating Amish settlements. Primarily using freely available Bing and Google maps and published lists of the addresses of Amish ministers, we geolocated 1,362 Amish households in Ohio and 1,203 in Pennsylvania, representing about 10% of Amish households in those states. From these data we were able to derive a population density map of the Amish across Ohio and Pennsylvania. We caution that our map is merely a model and based on several assumptions, but the product is a finer resolution map of Amish distribution than …
