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 …

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) …

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 …

Functional Approach To Simulating Short Rotation Woody Crops In Process Based Models, Tian Guo, Bernard Engel

Purdue GIS Day

Short rotation woody crops (SRWC) such as hybrid poplar have great potential as a biofuel feedstock. Biomass yields and yield stability at potential sites are important considerations when such SRWC is widely planted. To simulate poplar growth accurately, the functional components and parameters of hybrid poplar Tristis #1 (Populus balsamifera L. × P.tristis Fisch) were determined, and related algorithms improved in ALMANAC and SWAT based on improved simulation of leaf area and plant biomass as well as biomass partitioning. The improved tree growth simulation was applied to hybrid poplar plots in Wisconsin, and the modeled biomass yield, and LAI were …

China's Nine-Dashed Map: Maritime Source Of Geopolitical Tension, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The South China Sea (SCS) is becoming an increasingly contentious source of geopolitical tension due to its significance as an international trade route, possessor of potentially significant oil and natural gas resources, China’s increasing diplomatic and military assertiveness, and the U.S.’ recent and ongoing Pacific Pivot strategy. Countries as varied as China, Taiwan, the Philippines, Indonesia and other adjacent countries have claims on this region’s islands and natural resources. China has been particularly assertive in asserting its SCS claims by creating a nine-dash line map claiming to give it de facto maritime control over this entire region without regard to …

Automatic Extraction Of Plots From Geo-Registered Uas Imagery Of Crop Fields With Complex Planting Schemes, Anthony A. Hearst

Open Access Theses

Complex planting schemes are common in experimental crop fields and can make it difficult to extract plots of interest from high-resolution imagery of the fields gathered by Unmanned Aircraft Systems (UAS). This prevents UAS imagery from being applied in High-Throughput Precision Phenotyping and other areas of agricultural research. If the imagery is accurately geo-registered, then it may be possible to extract plots from the imagery based on their map coordinates. To test this approach, a UAS was used to acquire visual imagery of 5 ha of soybean fields containing 6.0 m2 plots in a complex planting scheme. Sixteen artificial targets …

Evaluating Intensity As A Controller Function For Nextgen Scenarios With Increased Capacity, Caitlin Anne Surakitbanharn

Open Access Theses

Automated separation assurance is the most mature concept to handle increasing airspace traffic and capacity needs, yet the system lacks a way to pre-emptively identify aircraft separation problems. The intensity control measure looks to find situations where if an aircraft pair makes an unplanned change in heading or altitude at the wrong moment, an unrecoverable situation arises. This research analyzes static, open loop air traffic data in an en-route sector to determine how many high intensity aircraft pairs (HIP) exist per minute, and if the intensity measure is a safely manageable function for air traffic controllers. It is found that …

Development Of A Real Time Bistatic Radar Receiver Using Signals Of Opportunity, Nicholas Rainville

Open Access Theses

Passive bistatic radar remote sensing offers a novel method of monitoring the Earth's surface by observing reflected signals of opportunity. The Global Positioning System (GPS) has been used as a source of signals for these observations and the scattering properties of GPS signals from rough surfaces are well understood. Recent work has extended GPS signal reflection observations and scattering models to include communications signals such as XM radio signals. However the communication signal reflectometry experiments to date have relied on collecting raw, high data-rate signals which are then post-processed after the end of the experiment. This thesis describes the development …
