Estimation Of Forest Interior Condition In Southern Appalachian Mountains Using Airborne Lidar Data, Gang Shao, Songlin Fei, Buddhika D. Madurapperuma, Guofan Shao
Purdue GIS Day
Sustainability of forest ecosystem requires maintenance of forest cover and forest interior conditions. Sustaining forest cover supplies ecosystem goods and services and maintains biomass and carbon and nitrogen storage. Forest interior supports ecosystem functioning and provides particular physical and biological environments for plant and animal species that depend on a type of habitat isolated from non-forest land cover areas and prohibit the infestation of invasive species. Land cover maps derived from satellite imagery were broadly applied to assess spatial patterns of forest ecosystem and its dynamic. However, existing land cover maps at landscape scale are insufficient to provide information of …

This study examines how the vertical structure of forests and the variation in forest canopy tree composition relates to where forest plant invasions occur at a regional scale. We used LiDAR data on vertical structure of forests collected across 16 counties of western North Carolina, and Forest Inventory and Analysis (FIA) abundance data of invasive plant species and canopy tree species from 575 plots. We found that nearly one third of these plots were invaded by at least one invasive plant species (range = 1 to 8 species). We derived canopy gaps/clear-cut areas of the study site using LiDAR data …

Python Tool For Managing Hydrologic Soil Data, Ilyas Orazbek
Purdue GIS Day
As a water runoff crosses different kinds of soil, it collects chemicals from those lands. We've designed a python-based tool that estimates the amount of chemicals that get collected into the water stream. This could help us determine the impact of construction on the water quality of streams in the area.

Beyond Gis: The Promise Of Spatial Humanities, David J. Bodenhamer
Beyond Gis: The Promise Of Spatial Humanities, David J. Bodenhamer
Purdue GIS Day
Geospatial technologies such as Geographic Information Systems (GIS) have facilitated the (re)discovery of space for humanists. Yet until recently GIS has had only limited ability to move us beyond a map of geographical space into a richer, more evocative concepts of place based on history and memory. Over the past few years, GIScientists have made advances in spatial multi-media, in GIS-enabled web services, geo-visualization, cyber geography, and virtual reality that provide capabilities far exceeding the abilities of GIS on its own. This presentation will explore how the convergence of technologies, including but not limited to GIS, has led to the …

The Emerging American Empire: Republican Capitalist Development In The Usa, 1830-1930, Richard Hogan
The Emerging American Empire: Republican Capitalist Development In The Usa, 1830-1930, Richard Hogan
Purdue GIS Day
Capital Accumulation, territorial expansion, and the rise and fall of political party systems mark the history of the American Empire, 1830-1930. During this time, the USA emerged from colonial dependency at the edge of the British Empire (after the War of 1812) and established a bipartisan political system (after the election of Jackson in 1828), which was destroyed by the irrepressible conflict between institutionalized Slavery and the challenge of Abolitionism, 1830-1860, culminating in the Civil War. After the election of 1860, a new bipartisan system and renewed industrial capitalist expansion (especially after the political storm from Reconstruction to Populism, 1876-1896) …

Tablet-Based Mobile Gis Approaches To Archaeological Data Collection, Ian Lindsay
Tablet-Based Mobile Gis Approaches To Archaeological Data Collection, Ian Lindsay
Purdue GIS Day
Over the past 15 years, archaeological research in northern Armenia has documented the unique evolution of prehistoric complex societies in the South Caucasus, where complex, fortress-centered institutions emerged during the Late Bronze Age (c.1500-1150 BC) not from settled farming villages—as is more typical of archaic states—but from mobile herding communities. As the costs of archaeological fieldwork continue to rise, resulting in shorter and more intensive field seasons, researchers are leveraging new technologies to improve the efficiency and accuracy of data collection in the field. An increasingly popular solution in archaeology is the use of “paperless” site recording strategies that enhance …

From Social Media Data To Human Behavior Patterns: Analyzing Spatio-Temporal Dynamics Of Tweets In Midwest College Towns, Yue Li, Jie Shan
Purdue GIS Day
Twitter, the most popular micro-blogging site, having over 500 million registered users as of 2012 and creating over 340 million tweets per day, has caught the attention of socio-geographic researchers. With its availability from mobile phones, Twitter allows users to send messages with their geographic coordinates. Thus, with respect to the huge quantity and large diversity of crowds publishing tweets, massive valuable geosocial knowledge can be extracted, which can provide important implications for various applications, such as human geography, urban science, location-based services, targeted advertising, content delivery networks, and social media research. This study aims to uncover human behavior patterns, …
