Theses and Dissertations (Comprehensive)
During the summer months of July and August 1989, approximately 23 years after a photogrammetric survey on August 22, 1966, Peyto Glacier, a glacier selected for study during the International Hydrologic Decade (IHD) 1965-74, was re-surveyed using terrestrial geodetic surveying techniques. The volumetric and morphologic change of Peyto Glacier, Alberta from 1966 to 1989 is estimated through a combined application of digital cartometry, digital geodetic survey and Triangulated Irregular Network (TIN) digital terrain modeling and analysis. Changes in glacial volume, areal extent, teriminus position, percentage basin glaciation, slope, and aspect for the 23 year interval are shown. Additionally, a 1:10000 …
