Multi-Scale Flow Mapping And Spatiotemporal Analysis Of Origin-Destination Mobility Data, Xi Zhu

Theses and Dissertations

Data on spatial mobility have become increasingly available with the wide use of location-aware technologies such as GPS and smart phones. The analysis of movements is involved in a wide range of domains such as demography, migration, public health, urban study, transportation and biology.

A movement data set consists of a set of moving objects, each having a sequence of sampled locations as the object moves across space. The locations (points) in different trajectories are usually sampled independently and trajectory data can become very big such as billions of geotagged tweets, mobile phone records, floating vehicles, millions of migrants, etc. …

Integrated Analysis Of The Value Of Wetland Services In Coastal Adaptation; Methodology And Case Study Of Hampton-Seabrook Estuary, New Hampshire, Paul Kirshen, Semra Aytur, David M. Burdick, Diane Foster, Tom Lippmann, Ellen Douglas, Sydney Nick, Chris Watson

Jackson Estuarine Laboratory

The present impacts from coastal storms and high tides grow significantly over time due to SLR even over the relatively short period to 2060. Hydrodynamic model simulations of storm surge with and without sea level rise scenarios show that although flooding and inundation increases with increasing subtidal forcing and higher sea level, dissipation of the tide and storm surge in the estuary channel somewhat limits the maximum inundation that might otherwise be expected in the back marsh areas. The estuary is dominated by high marsh, which lies high in the intertidal zone and by 2060 it will convert to mostly …

Remote Sensing Methods And Applications For Detecting Change In Forest Ecosystems, David James Gudex-Cross

Graduate College Dissertations and Theses

Forest ecosystems are being altered by climate change, invasive species, and additional stressors. Our ability to detect these changes and quantify their impacts relies on detailed data across spatial and temporal scales. This dissertation expands the ecological utility of long-term satellite imagery by developing high quality forest mapping products and examining spatiotemporal changes in tree species abundance and phenology across the northeastern United States (US; the ‘Northeast’).

Species/genus-level forest composition maps were developed by integrating field data and Landsat images to model abundance at a sub-pixel scale. These abundance maps were then used to 1) produce a more detailed, accurate …

Exploring Spatial And Temporal Variability Of Soil And Crop Processes For Irrigation Management, Javier Reyes

Theses and Dissertations--Plant and Soil Sciences

Irrigation needs to be applied to soils in relatively humid regions such as western Kentucky to supply water for crop uptake to optimize and stabilize yields. Characterization of soil and crop variability at the field scale is needed to apply site specific management and to optimize water application. The objective of this work is to propose a characterization and modeling of soil and crop processes to improve irrigation management. Through an analysis of spatial and temporal behavior of soil and crop variables the variability in the field was identified. Integrative analysis of soil, crop, proximal and remote sensing data was …

Cannabis In Cascadia: Impacts Of Legalization In The Region, Border Policy Research Institute

Border Policy Research Institute Publications

The policies regulating the use and sale of cannabis have historically been constructed differently in the United States and Canada, yet both countries had deemed recreational use to be illegal. Beginning in 2012, however, individual states in the U.S. began to legalize recreational cannabis, including Washington, Oregon, and most recently, California. In 2017, the Government of Canada passed similar legislation. If Canada’s legislation goes into effect in mid-2018, the West Coast of North America will become the only contiguous region where recreational consumption and sale of cannabis are permitted across multiple jurisdictions (see Map 1, next page). However, because cannabis …

Assessing Historical Planform Channel Change In An Altered Watershed With Quantification Of Error And Uncertainty Present In A Gis/Aerial Photography-Based Analysis; Case Study: Minnesota River, Minnesota, Usa., Devon Libby

All Graduate Theses, Dissertations, and Other Capstone Projects

Little is known about the historic planform channel change of the Minnesota River of south-central Minnesota, USA. This is despite research that demonstrates anthropogenic activities have altered the Minnesota River Basin's hydrology, land use, and climate. In addition, the threat of invasive carp infestation requires an understanding of Minnesota River planform change to assess mitigation strategies. This thesis focuses on the lower Minnesota River (LMR) by measuring planform channel change (lateral channel migration, width, and sinuosity) from 1937 to 2013. Analysis is conducted by utilizing remote/GIS analysis of historic aerial photographs. A secondary focus addresses and quantifies the inherent/introduced error/uncertainly …

Tweets About Tornado Warnings: A Spatiotemporal And Content Analysis, Raelene C. Campbell

Theses and Dissertations

Throughout the United States, tornadoes frequently occur throughout the entire year. With each tornado there is a tornado warning that the National Weather Service (NWS) issues with a goal of protecting life and property. By using social media, these messages quickly reach the public. By analyzing Twitter data, this study aims to gain a spatiotemporal understanding of tweets, including when and where they most frequently occur. Most tweets occur within the warning time (temporal) and inside the warning polygon (spatial). To gain a better understanding of the information the tweet contains, a content analysis shows key warning characteristics such as …

Cemetery Management In A Gis Framework: A Case Study Of Woodland Hills Memorial Park, Maureen Schmidt

All Graduate Theses, Dissertations, and Other Capstone Projects

his paper aims to examine the potential uses and applications of geospatial technologies for cemetery management. The Woodland Hills Memorial Park in Mankato, Minnesota, was used as a case study. The hard copy, handwritten records of the Woodland Hills Memorial Park were converted to digital formats, and then combined with GPS gathered data using GIS. The traditional method of storing and keeping these records is time consuming, as the curator must hand write all the information into the physical books. The maps of the park are also hand-drawn, which makes their examination and upkeep tedious. By creating digital copies of …

Modeling Pre-Settlement Wetlands In Northern Minnesota, Johnathon T. Salfer

All Graduate Theses, Dissertations, and Other Capstone Projects

Modern land use has dramatically altered the native landscape across much of Minnesota and the United States. “Manifest Destiny” has ingrained the idea in American society that wetlands and related lands of “low value” need to be tamed and made profitable. In many places, wetlands have been drained and removed so that agriculture can take over. In recent years, people have begun to see the unintended consequences of this method, and importance is now being given to natural wetlands through various government projects and programs. Using National Wetlands Inventory (NWI) data, Drainage Index (DI) values calculated from Soil Survey Geographic …

Effects Of Manual And Mechanical Ammophila Arenaria Removal Techniques On Coastal Dune Plant Communities And Dune Morphology, Monique R. Silva Crossman

Cal Poly Humboldt theses and projects

The removal of invasive species as part of the restoration process can allow natives organisms to rebound. An ecosystem that incurs damages from invasive species is coastal sand dunes, which are dynamic systems. Some coastal sand dunes on the west coast of the United States have been invaded by Ammophila arenaria. The invasive grass, A. arenaria, is thought to alter and stabilize foredune morphology and reduce populations of native species. The objectives of my research are to examine the effects that manual and mechanical A. arenaria removal techniques have on coastal sand dune morphology and vegetative cover over time. …

Virunga: Guns, Gorillas, And The Construction Of Transnational Natures, Adriana Disilvestro

Honors Theses

The recent western media attention surrounding Virunga National Park in the Democratic Republic of Congo, has brought up significant scholarly questions about the discursive portrayal of “ideal” Natures. In this thesis, I undertake a discursive analysis of western media materials about Virunga National Park in order to understand how ideas of Nature are transnationally constructed. In order to do this, undertake an analysis of the western oriented discursive material associated with three socio-political processes within the park: green militarization, gorilla trekking, and the ecotourist industry. Ultimately, I conclude that the discursive material portrays a highly spectacularized and commodified “ideal” nature, …

Data: Pre-Fire Disturbance History Modulates Relationships Between Ground Cover And Post-Fire Conifer Regeneration, Nathan Gill, Dan Jarvis, Tom Veblen, John Rogan, Dominik Kulakowski

Student Works

Understory vegetation and ground cover drive many important ecosystem processes, including tree seedling regeneration. The exact effect of ground cover on tree seedling establishment, survival, and growth depends on biophysical context. In subalpine forests, this context is largely determined by disturbances such as beetle outbreak, blowdown, and fire. Compounded disturbances that overlap in short succession can alter stand properties and trajectories in ways that are not predictable from the additive impact of individual disturbances. The aim of this study is to examine how compounded Dendroctonus rufipennis (spruce beetle; SB) outbreak followed by fire and compounded wind blowdown followed by fire …
