Processing Procedures - DF026:

Description:

DF02601: This landslide data was developed through an iterative process that included multiple phases of GIS screening, field data collection, inventory comparisons, and peer reviews. For this final release of the data, further processing by GIS software was done to improve data quality. The following tasks were completed:

• the county boundary file was corrected to remove small 'no data' areas , and checked for topology.
• the Oregon coast shoreline was improved using a NOAA-developed shoreline file obtained from the Oregon Department of Land Conservation and Development.
• a 100-meter westward buffer was applied to the new shoreline along the entire Oregon coast.
• a 100-meter buffer was applied beyond the perimeter of each county data file (and subsections) to ensure data continuity.
• very small polygons (less than 450 square meters) were removed.
