Title

Assessment of atmospheric errors on GPS in the Arctic

Description

GPS is used throughout the world for navigation and positioning. Growing interest in the Arctic region predominantly due to a reduction in ice coverage suggested that an investigation should be carried out on region-specific errors in GPS for high accuracy users.

Title

Improving the Accuracy of ASTER data for Glacial change in Antarctica

Description

Through collaboration with the British Antarctic Survey (BAS) the research was applied to a test site located on the western Antarctic Peninsula at Pourquoi Pas Island. This encompassed a glacier system, extending over an area of 86 km2, and providing a variety of terrain types over which to investigate the approach. In addition to an ASTER DEM, a high-accuracy DEM, derived from aerial
photography captured at the same time as the ASTER data, was available for the site. This provided a strong basis for the validation exercise, as any systematic offsets between the datasets will be due to registration deficiencies rather than terrain change.
