The Impact Of Management On The Movement And Home Range Size Of Indiana's Eastern Hellbender Salamanders, Emily B. Mccallen, Bart T. Kraus, Nick G. Burgmeier, Rod N. Williams

Purdue GIS Day

Eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) are a large, fully aquatic salamander species distributed throughout watersheds in the eastern United States. In Indiana, hellbenders were once found in tributaries of the Ohio River and the Wabash River but are now restricted to a single river in the southern portion of the state. Monitoring within the Blue River over twenty years has revealed a steady decrease in the total abundance of hellbenders and a shift towards older individuals in the age structure of the population. Concerned over the apparent lack of recruitment, the Indiana department of natural resources performed a series of …

Predicting U. S. Presidential Elections: From 1900 Until Today, Richard L. Hogan

Purdue GIS Day

This presentation is scheduled for the weekend before the presidential election of 2016. By then, we might all need a break from pollsters and predictions, although we still might be looking for some assurance that this will not be the end of Western Civilization as we knew it. Toward that end, a little historical perspective on presidential elections since 1900, complete with cool maps, of course, indicating partisanship by state, will illustrate several important hypotheses that the data suggest we might incorporate in our efforts to predict the future by explaining the past. Neither candidate has approved this message.

Gis In Archaeology: The Pedestrian Survey Of Dana Island In Turkey, Noah Kaye, Gunder Varinlioglu, Nicholas K. Rauh

Purdue GIS Day

An international team of archaeologists conducted a surface survey of the remains on Dana Island, ancient Pithussae, near Silifke in south Coastal Turkey. The island sits 2 km offshore and is uninhabited. Architectural remains of stone quarries, large cisterns, houses and churches extend approximately 1.6 km along its western coast. At the crest of the mountain that rises above the shore stands the remains of an Iron Age fortress incorporated into later Byzantine structures. Relying on a base map constructed of the Google earth view of the island, digitized topographical maps, and an aerial photograph from 1990, the pedestrian team …

How Gis Will Support Next Gen 9-1-1, Jim I. Sparks

Purdue GIS Day

While most practitioners have a general awareness that GIS will play a more prominent role in Next Generation 9-1-1, few have much definitive information about what that means for Indiana GIS. This presentation will provide background information and an introduction to the requirements that NG 9-1-1 will place on our location data. Time will be left for some discussion centered on the challenges that are ahead of us.

Spatial Analysis Of Landfills In Respect To Flood Events And Sea-Level Rise, Benjamin S. Taylor, Songlin Fei

Purdue GIS Day

Recently in the news, media coverage of flood events has garnered much attention due to tropical storms like Hurricane Matthew and the costly damages that resulted. Under climate change, events like sea-level rise (SLR) and flooding threaten infrastructure, which make it necessary for proper planning before, during, and after installation to mitigate risk. Studies in Austria and the UK have revealed that many landfills are located in flood zones as well as coastal areas effected by coastal erosion. In the U.S. however, there have not been publications on landfill locations related to flood events and SLR. The interest of gaining …

Introduction To The New Indiana Geospatial Coordinate System (Ingcs), Matthew Badger

Purdue GIS Day

The Indiana Geospatial Coordinate System (InGCS) was approved and adopted by INDOT in 2015 and will soon be the primary coordinate reference system used on INDOT survey and design projects. Other agencies and organizations in the geospatial arena are encouraged to make use of this system of low distortion projections as well. Many of the more widely used geospatial software vendors have since included the InGCS in their platforms to support their customers’ needs. Please refer to the InGCS webpage at www.in.gov/indot/InGCS.htm for additional information.

Speaker Bio: Matthew G. Badger, P.S. Matt has been a licensed Professional Surveyor in Indiana …

Analyzing The Native-Exotic Richness Relationship Using Native Beta Diversity, Gabriela C. Nunez-Mir, Songlin Fei

Purdue GIS Day

Invasion paradox, a change of direction in native-exotic richness relationships (NERRs) from negative at small scales to positive at large scales, has been shown to exist in many environments. A major explanation for these patterns is environmental heterogeneity, and to a lesser extent, species pool size. It is likely that a combination of these factors is producing these patterns and determines if and how they appear in certain environments. Beta diversity, which describes the heterogeneity of species composition among assemblages and as the scalar between local richness and regional richness (species pool size), could serve as a proxy for these …

Mapping Religion And Chinese Society, Jonathan E.E. Pettit

Purdue GIS Day

Over the past two decades, the Chinese government has enacted a series of regulations that have made the collection of geospatial data illegal, and have tried to use existing technologies (e.g., cell phone towers, online mapping programs) to avert attempts to map sensitive areas in China. This talks examines the recent work of Purdue graduate students at the Center on Religion and Chinese Society, who have developed a web-based GIS program that provides researchers worldwide a way to make and use accurate data on religious and demographic data in China.

Geospasial Indonesia: The Utilization Of Spatial Data Through Geographic Information Systems Across Indonesia In Various Environmental Contexts, Kaitlyn Bretz

Independent Study Project (ISP) Collection

Spatial planning and mapping in Indonesia have had a precarious history for the past several decades. Laws controlling the creation of maps for land use planning have fluctuated greatly between executive administrations and the country is still struggling to create a single, unified national map. With the One Map Policy the future of mapping is optimistic, but in the meantime spatial data analyses are lacking. Geographic information systems (GIS) is a computerized system for the capture, storage, querying, analysis, and display of spatial data, and is used predominately by the government, private companies, and nongovernmental organizations (NGOs) across Indonesia. Community …

Women In The Gis Profession, Livia Betancourt-Mazur, Jochen Albrecht

Publications and Research

In many technical professions, women are underrepresented. While a gender imbalance also has been assumed to exist in the realm of professional GIS, no data existed to corroborate it. The original survey presented here was developed by the authors to add both quantitative and qualitative research about the numbers and current experience of women in GIS to address this knowledge gap. A total of 484 women responded to the survey, providing a healthy sample size and a reliable and informative data set.

A key finding is that some 42 percent of women are, overall, not grossly underrepresented in the GIS …

Merging Volunteered Geographic Information Systems, James Mcandrew

Geography and the Environment: Graduate Student Capstones

This project determines how two different systems based on geographic user-generated content can work together to allow the content to be made more accessible. This project’s objective is to determine the technical and social issues involved with allowing information to be transferred between systems.

Specifically, this project works with information from two volunteer systems: 1) The United States Geological Survey’s National Map Corps, 2) A global volunteer mapping project called OpenStreetMap.

This project discusses the history of both systems and how they have dealt with importing data in the past. It reviews what has worked well with previous imports and …

Variability Of Lacustrine Sediment Proxy Responses To Late Holocene Climate Change As Modified By Lake Specific Processes: A Review Of Ecological And Geophysical Processes Across Northern And Eastern Iceland, Mallory Mintz

Independent Study Project (ISP) Collection

Consistenly-deposited lake sediments provide some of the highest resolution records of local and global climates in the past, offering the potential to better understand modern climate change in the context of past climate variability. In relating proxies to their respective climate regimes, the environmental cues that the specific proxies reacted to must be isolated from the general noise of possible local influences. In this investigation, biogenic silica (BSi), total organic carbon (TOC), δ13C values, and carbon: nitrogen ratios were analyzed between lakes through northern Iceland, to review possible complicating factors specific to the use of lacustrine proxies in the interpretation …

Proxy Dating In Iceland Testing The Validity Of Silene Acaulis As A Phytometric Proxy, Madelyn Grant

Independent Study Project (ISP) Collection

Climate change is causing drastic changes in the cryosphere, particularly in the Arctic region where average warming is 1.9 times greater than in the rest of the world due to Arctic amplification. Understanding the response of essential climate variables such as glaciers and ice caps to rapid Arctic warming is essential to predicting future changes in the Arctic region and around the world. Proxy dating methods can help construct a record of warming-induced glacial retreat in areas where long-term monitoring systems are not in place. In Arctic regions, the cushion plant Silene acaulis represents one of the only feasible proxies …

Investigating Effects Of Climate Change On Glaciers And Proglacial Landscapes In Southeast Iceland: Fluvioglacial Behavior Of Sólheimajökull And Seljavallajökull, Roberta B.C. Miller

Independent Study Project (ISP) Collection

The Seljavallajökull glacier, part of the Eyjafjallajökull glacier system, and Sólheimajökull, part of the Mýrdalsjökull glacier system, are two glaciers that extend into valleys in the southeast part of Iceland. Due to climate warming, both of these glaciers are part of a melting ice cap. They are located nearby to one another, and Sólheimajökull has been extensively studied for its outwash plain sedimentology, retreat history, pro-glacial geomorphology and has been steadily monitored by the Glaciological Society of Iceland. Seljavallajökull has also been monitored by this group, but it has not been studied for sediment profiles and landscape chronology as Sólheimajökull …
