Early Detection Of Mountain Pine Beetle Damage In Ponderosa Pine Forests Of The Black Hills Using Hyperspectral And Worldview-2 Data, Kyle Edward Mullen
Early Detection Of Mountain Pine Beetle Damage In Ponderosa Pine Forests Of The Black Hills Using Hyperspectral And Worldview-2 Data, Kyle Edward Mullen
All Graduate Theses, Dissertations, and Other Capstone Projects
A leading cause for mortality in the pine forests of western North America, the mountain pine beetle, has impacted over 400,000 acres of ponderosa pine forest in the Black Hills of South Dakota since 1996. Methods aimed at earlier detection, prior to visual manifestation of a mountain pine beetle damage in the tree crown, have not been successful because of the overlap and variability of spectral response between the initial stages of attack (green-attacked) and non-attacked tree crowns. Needle-level reflectance spectra was measured from green-attack and non-attack ponderosa pine trees in early spring following an infestation and analyzed using a …
Land Cover Mapping And Change Analysis At The Tensleep Preserve In Wyoming, Tyler Richard Grupa
Land Cover Mapping And Change Analysis At The Tensleep Preserve In Wyoming, Tyler Richard Grupa
All Graduate Theses, Dissertations, and Other Capstone Projects
Mapping land cover and land cover change are important, especially for land managers who protect natural lands and generate restoration projects. Accurate land cover assessment of rangelands can be difficult because the spectral difference between plant species may be minimal. The goal of this research is to map the land cover in the Tensleep Preserve and highlight change that has occurred over the past twenty-three years using the Feature Analyst extension. The land cover change map will highlight significant changes and Feature Analyst will accurately identify different land covers using historical aerial photographs and ground truthing data collected in 2013. …
Cleaning Up Minnesota's Archeological Record With Maid: The Minnesota Archeological Integrated Database, Andrew Allen Brown
Cleaning Up Minnesota's Archeological Record With Maid: The Minnesota Archeological Integrated Database, Andrew Allen Brown
All Graduate Theses, Dissertations, and Other Capstone Projects
Minnesota archeologists face many difficulties in conducting archeological research and managing the state's cultural resources such as a lack of standardized data formats and field/lab procedures, a lack of a centralized data repository, and insufficient existing databases. The purpose of this thesis is to build the foundation for a database system that addresses these difficulties along with being efficient and effective for entering, managing, and analyzing archeological data produced in the field and in the lab. The Minnesota Archeological Integrated Database is being built to be a long-lasting, constantly evolving system to be used by archeologists and cultural resource managers …
