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.

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.

The Potential Of Forest Biomass Inversion Based On Vegetation Indices Using Multi-Angle Chris/Proba Data, Qiang Wang, Yong Pang, Zengyuan Li, Guoqing Sun, Erxue Chen, Wenge Ni-Meister

Publications and Research

Multi-angle remote sensing can either be regarded as an added source of uncertainty for variable retrieval, or as a source of additional information, which enhances variable retrieval compared to traditional single-angle observation. However, the magnitude of these angular and band effects for forest structure parameters is difficult to quantify. We used the Discrete Anisotropic Radiative Transfer (DART) model and the Zelig model to simulate the forest canopy Bidirectional Reflectance Distribution Factor (BRDF) in order to build a look-up table, and eight vegetation indices were used to assess the relationship between BRDF and forest biomass in order to find the sensitive …

How Mature Capitalism Turns Pollution Into Diamonds: Malagnogenesis And The Reverse-Engineering Of Harm Into Risk, Kevin P. Martyn

USF Tampa Graduate Theses and Dissertations

In recent years, there has been a great deal of debate about the pervasiveness and persistence of neoliberal thinking. In the context of the post-2008 ‘great recession’ the resilience of neoliberalism is particularly confounding. To begin to unravel the ways in which neoliberalism is situated relative to risk, this study identifies an increasingly important neoliberal knowledge practice: malagnogenesis. Malagnogenesis is proposed herein as the production of ignorance that normalizes harm for and amongst marginalized populations. To shed light on the phenomena of malagnogenesis, this study investigated the history of leaded gasoline in the U.S. To that end, I …

Differential Heating In The Indian Ocean Differentially Modulates Precipitation In The Ganges And Brahmaputra Basins, Md Shahriar Pervez, Geoffrey M. Henebry

GSCE Faculty Publications

Indo-Pacific sea surface temperature dynamics play a prominent role in Asian summer monsoon variability. Two interactive climate modes of the Indo-Pacific—the El Niño/Southern Oscillation (ENSO) and the Indian Ocean dipole mode—modulate the amount of precipitation over India, in addition to precipitation over Africa, Indonesia, and Australia. However, this modulation is not spatially uniform. The precipitation in southern India is strongly forced by the Indian Ocean dipole mode and ENSO. In contrast, across northern India, encompassing the Ganges and Brahmaputra basins, the climate mode influence on precipitation is much less. Understanding the forcing of precipitation in these river basins is vital …

Rapid Land Cover Map Updates Using Change Detection And Robust Random Forest Classifiersrapid Land Cover Map Updates Using Change Detection And Robust Random Forest Classifiers, Konrad J. Wassels, Frans Van Den Bergh, David P. Roy, Brian P. Salmon, Karen C. Steenkemp, Bryan Macalister, Derick Swanepoel, Debbie Jewitt

GSCE Faculty Publications

The paper evaluated the Landsat Automated Land Cover Update Mapping (LALCUM) system designed to rapidly update a land cover map to a desired nominal year using a pre-existing reference land cover map. The system uses the Iteratively Reweighted Multivariate Alteration Detection (IRMAD) to identify areas of change and no change. The system then automatically generates large amounts of training samples (n > 1 million) in the no-change areas as input to an optimized Random Forest classifier. Experiments were conducted in the KwaZulu-Natal Province of South Africa using a reference land cover map from 2008, a change mask between 2008 and …

Separability Analysis Of Sentinel-2a Multi-Spectral Instrument (Msi) Data For Burned Area Discrimination, Haiyan Huang, David P. Roy, Luigi Boschetti, Hankui Zhang, Lin Yan Dr., Sanath Sathyachandran Kumar, Jose Gomez-Dans, Jian Li

GSCE Faculty Publications

: Biomass burning is a global phenomenon and systematic burned area mapping is of increasing importance for science and applications. With high spatial resolution and novelty in band design, the recently launched Sentinel-2A satellite provides a new opportunity for moderate spatial resolution burned area mapping. This study examines the performance of the Sentinel-2A Multi Spectral Instrument (MSI) bands and derived spectral indices to differentiate between unburned and burned areas. For this purpose, five pairs of pre-fire and post-fire top of atmosphere (TOA reflectance) and atmospherically corrected (surface reflectance) images were studied. The pixel values of locations that were unburned in …

Independent Study Project: Investigation Into The Implications Of Zooarchaeological Studies For Climate Reconstruction In The North Atlantic; Zooarchaeological Research At The Agricultural University Of Iceland, Reykjavík, Hazel Cashman

Independent Study Project (ISP) Collection

Zooarchaeology, the study of animal remains from archaeological sites, is crucial to the understanding of human interaction with the environment in the North Atlantic region and in Iceland, where the archaeological record is quite rich (Dugmore et al., 2005). Since its inception, zooarchaeology has drawn methods and concepts from both the natural and social sciences, as well as from history and the humanities, to inform an interdisciplinary understanding of the interactions between humans and their environments and the consequences of these interactions for humans and animals (Reitz and Wing, 2008). In this way, zooarchaeology can inform discussions about historical anthropogenic …

What Is The Taste Of Co2? The Sustainability Of Icelandic Food Systems In The Face Of Climate Change, Molly Peek

Independent Study Project (ISP) Collection

Food security in the arctic and subarctic is an area of growing research and concern as climate change continues to alter the availability of traditional foods eaten in remote areas, especially as shipping food has questionable sustainability and contributes to rising CO2 levels. Previous research has noted changes in the Icelandic diet making it more reliant on foreign imports, although there is still strong localized agriculture. Because of its geothermal activity, Iceland has a unique advantage over other highlatitude countries in growing food with a minimal carbon footprint, although that potential is unequal throughout the country. This study utilized available …

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 …

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 …
