GIS data of analysis results

Metadata Updated: November 12, 2020

This project resulted in an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work provides important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, was known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast was not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of recent habitat loss. Hotspots of change identified by the wide coverage of the mapping are available to provide guidance on selecting areas for monitoring or for more intensive research (e.g., terrain sensitivity analysis).

Note that the results for the 60 m time-series analysis should be considered more robust; they have a longer time-series with high data availability at the start of the study period and were the focus of algorithm development and evaluation. Zip files with the core results for the full time-series analysis (1972–2013) and the shorter time-series analysis (1985–2013) can be downloaded. Zip packages that include additional support rasters are also provided.
