DGGS collected and processed the lidar data and conducted the landslide susceptibility mapping for this project with funds from the Federal Emergency Management Agency (FEMA) Cooperating Technical Partners (CTP) Program, grant number CTP EMS-2021-CA-00014-01. We thank our reviewers, Dennis Staley (U.S. Geological Survey) and Nealey Sims (DGGS), for their thoughtful comments and suggestions, which improved the quality of this product. We also thank Bretwood Higman for sharing his unpublished landslide mapping of the Cordova area, which we incorporated into our inventory.
The purpose of this geodatabase is to give communities, planners, and emergency managers a consistent, openly available baseline for identifying where slope failures are most likely to threaten people and infrastructure. By helping prioritize areas for detailed investigation before development or disaster occurs, the data support safer land-use decisions, reduce potential losses, and strengthen the resilience of Alaska communities, which face growing landslide hazards from severe storms and retreating glaciers. The data are intended for regional, community-scale use at the published map scale of 1:25,000 and are not suitable for site-specific, regulatory, engineering, or legal purposes.
