QA/QC Attribute check 1: All field values are consistent with the domains listed in the SLIDO-4.0 Appendix D: Update Procedure. This check was a general attribute check. Attribute check 2: Field Unique_ID does not contain any duplicates. This check was performed to ensure all records have only one primary key. Attribute check 3: Historical Landslide Points feature class is fully attributed when applicable and available. This check is performed because most attributes are housed in this feature class.

The Historic Landslide Point feature class is a complete compilation of all published or known historic landslide deposits as center points within the state of Oregon (see accompanying report for souces); with the exceptions of landslides smaller than 100 square meters (1,075 square feet) which may not be identified due to the resolution of the lidar data and air photos used in this project area, and/or landslides older than 1929.
While compiling the data where previously mapped landslide inventories are available, landslides have been inspected and confirmed. This check is for cross referencing current landslide mapping with historical mapping. Data has not been altered from original publications, so errors may still exist. Null values indicate that no information about that specific attribute was available at that time.
Historic landslide points were manually placed and may not display a high level of horizontal accuracy.
Lineage maps were used as base maps in the following manner: 1) to compare the mapping against previous work; 2) identifying geologic units; and 3) reference materials.
