Gis Applications To Glaciology: Construction Of The Mount Rainier Glacier Database, Jeremy Laurence Mennis
Gis Applications To Glaciology: Construction Of The Mount Rainier Glacier Database, Jeremy Laurence Mennis
Dissertations and Theses
This thesis explores the application of Geographic Information Systems (GIS) to glaciology through the construction of a GIS database of glaciers on Mount Rainier, Washington (the Database). The volume and areal extent of these glaciers, and the temporal change to each, are calculated as a demonstration of GIS analytical capabilities. Data for Carbon, Cowlitz, Emmons, Nisqually, Tahoma, and Winthrop glaciers for the years 1913 and 1971 are derived from historic topographic maps. The Database includes two and three-dimensional representations of glacier geometry, such as glacier extent and topography, as well as surface features, such as debris cover. A test of …
Managing Oregon’S Aquatic Resources : A Dynamic Segmentation Application, Keith Andrew Hupperts
Managing Oregon’S Aquatic Resources : A Dynamic Segmentation Application, Keith Andrew Hupperts
Dissertations and Theses
Many of Oregon's salmon, the cultural icon of the region, are imperil. Salmon runs ranging from the Snake River to the Oregon coast, from chinook to coho to steelhead to cut-throat are being protected or candidates for protection under the federal Endangered Species Act of 1973. As Oregon's salmon decline natural resource agencies, such as Oregon Department of Fish and Wildlife (ODFW), are seeing substantial funding cutbacks. In order to compensate for lost personnel and rising work-loads, ODFW is increasingly turning to new technologies, such as Geographic Information Systems (GIS). This thesis describes the creation of a dynamic segmentation GIS …
