2024 KEFJ Pedersen Lagoon Landslide SfM Imagery and GNSS

Published by National Park Service | Department of the Interior | Catalog Last Checked: August 01, 2026 at 03:58 AM | Dataset Last Updated: May 21, 2025 at 12:00 AM
Orthomosaics and Digital Surface Models of Pedersen Lagoon, the toe of Pedersen Glacier, and surrounding areas in Kenai Fjords National Park. These data were collected using Structure from Motion techniques on August 9, 2024 in response to the August 7 landslide and tsunami that flowed water into the Kenai Fjords Glacier Lodge. GNSS ground control was conducted on August 12 and 13 collecting run-up heights, visible features for horizontal accuracy assessment, and vertical check points.
