Tongass National Forest, USDA Forest Service, R10, Tongass National Fores 20190813 vector digital data 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. Estimated initation points for the landslide inventory of the Tongass National Forest Proclamation Boundary. Intended to accompany the polygon feature class named TongassLandslideAreas. Updated in FY 2019 20170605 This landslide inventory has been ongoing in GIS since 2001. It was hardcopy before 2001.

All of the landslides have unique identifiers. This feature class includes all lands within the Tongass National Forest and ajacent private lands. It does not include the Skagway area of Glacier Bay National Park. All landslides were digitized from hard copy air photos or heads-up on GIS ortho photos. The data check tool set was used to make sure that each slide had a unique identifier 20170605 Vector Entity point 12014 8.98315284119521e-009 8.98315284119521e-009 Decimal Degrees D North American 1983 GRS 1980 6378137.0 298.257222101 LSPoints09042018 ESRI ESRI TREATMENT Whether the landslide has been treated Field visits Y Yes, treated Internal N No, untreated Internal OBJECTID Internal feature number.

E is for Estimated dates. The all of the date field or just the year is filled in. Most of the E dates look like E00002005 or E000-1998 means estimated date before 1998.
