资源简介：
This is the point feature class for theonce-over landslide inventory of the Tongass National Forest. Most of the landslide polygons were digitized on the 1998 to 2010 ortho photos in GIS. Many of them were age bracketed using air photos back to the 1929 Navy Trimegon photos. It includes both field and photo interpreted landslides. This is only the point layer with initiation points for debris avalanches, debris torrents, combination debris avalances-debris torrents, slumps, rock fall initiated failures, and rotational failures.
