Locating A Wildlife Corridor For The Wild Tiger In India, Carmen George

Geography and the Environment: Graduate Student Capstones

The tiger (Panthera Tigris) has been on the ICUN red list of endangered species since 1972. In the early 20^th century, 100,000 wild tigers roamed Asia and today approximately 3,600 remain. India is home to over half of the remaining wild tigers and continues to struggle in creating effective conservation plans. Poaching, habitat destruction and prey depletion are several primary causes of tiger population degradation and remain major barriers to rejuvenation of healthy populations in the wild. Wildlife corridors are essential to the process of repairing fragmented habitats. Through the use of GIS and remote sensing this …

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 …

Mapping The Impact Of Famine On The Volga And Black Sea German Enclaves, 1891-1934, Amber N. Nickell

Purdue GIS Day

Using ArcGIS software and the ArcGIS online story mapping function, this project maps population growth and decline over time in the ethnic German Volga and Black Sea Enclaves in the Russian Empire (later the USSR) and overlays that population data with maps of famine zones during the 1891/2, 1921/22, and 1932/33 famines in order to answer the following questions. Where were the enclaves in relation to the famine regions? What impact did the famines have on ethnic German populations in the region? How did the Volga colonies fare in relation to national estimates during naturally occurring famines? During the manmade …

Launch Of Geodata Portal @ Purdue Libraries, Nicole Kong, Weichang Tang

Purdue GIS Day

With more than two years’ efforts, Purdue University Libraries are launching the Geodata Portal @ Purdue on this year’s GIS Day celebration. This geodata portal allows geospatial information users to search for information by two simple criteria: where and what, which greatly reduced the geospatial information access barrier for researchers and learners. Users can preview map, preview metadata, and download maps from the portal. Currently, our portal include data from: (1) open data at all the collaborating universities, including Tufts, Harvard, MIT, and Berkley; (2) data from IndianaMap; (3) Purdue open access map collection: historic aerial photos, topo maps, and …

Extended Capability To Support Multiple Watersheds In Stepl Web, Larry Theller, Kean Jye Tan

Purdue GIS Day

The STEPL model is a web-based spreadsheet tool designed for the estimation / of pollutant load and to analyze how creation or practicing certain sustainable / activities will reduce pollution in a watershed. For example, leaving a strip of / grass between a farm field and a water feature like stream of lake, will have an / estimated impact on the amount of soil and fertilizer which runs off in to the / river. / The model uses soil properties database, precipitation database and other / factors to make an estimate of pollution reduction after an action. It can then …

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.

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 …
